Lungs are one of the most important organs of the human body, without lungs people can not breathe, so the health of the lungs is also the basis of human survival. The modern living environment air pollution, coupled with people smoking, staying up late and other bad habits, the lungs have great damage. And when the lungs start to have disease, people will also have some relative reaction in life.

The most important symptom is the difficulty in breathing in the throat and respiratory tract, which is the most common and the most important symptom of lung disease, and the difficulty in breathing can be judged to be related to pneumonia to a certain extent.

When people have a cold and fever, due to the body's low immunity, people will have a cough, and when there is no disease, but always cough, especially in the middle of the night coughing sleep, with the existence of lung disease has a lot to do with the timely medical care.

Blood in the sputum, there are some people in the lungs have a disease, will occur after coughing up sputum, and if the sputum with blood, it is often more serious lung disease, do not rule out is lung cancer and other diseases, this situation should be timely attention.

Chest pain, which is a symptom of many lung diseases, is characterized by severe lateral chest pain, often pinprick-like, aggravated by coughing or deep breathing, and may radiate to the shoulder or abdomen. In the case of lower lobe pneumonia, it may irritate the septal pleura and cause severe abdominal pain, which is easily misdiagnosed as acute abdomen.

When the above symptoms appear, do not take it lightly, especially men, to smoke less or do not smoke. Keep the indoor environment ventilated, try to wear a mask when you go out in bad air, and use an air purifier if you have the conditions, as well as do regular medical checkups to detect abnormalities in time.

The lungs are the respiratory organs of the body and are the place of gas exchange, where air is exchanged through the lungs and oxygen enters the bloodstream, which then flows back to the heart. Through the beating of the heart, blood is transported throughout the body for use by the tissues and organs of the body.

Therefore, the most important sign of lung disease is hypoxia. After the lack of oxygen, all the regulatory and compensatory mechanisms in life will regulate respiration, deepen the movement, and increase the respiratory rate so as to ensure the supply of oxygen to the body. Therefore, the most important manifestations of lung disease are shortness of breath, shortness of breath, chest tightness, and in severe cases, even dyspnea.

In addition, when there is inflammation and infection in the lungs and other diseases, the lesions can irritate the pleura, and because there are a large number of pain sensory nerves distributed in the pleura, chest pain and chest tightness can also occur. And when there is a lesion in the lungs, the lesion compresses the normal lung tissues and trachea bronchi, and it causes an irritating cough. When there is an inflammatory infection in the lungs, there will be the presence of sputum, so coughing and sputum are also the most common clinical manifestations. When infections and neoplastic lesions in the lungs invade the tracheobronchial tubes and the vascular capillaries of the lungs, they can cause blood in the sputum or hemoptysis.

Chinese medicine on the physiological function of the lung is summarized as: Division breathing, the main line of water, towards the hundred veins, the main section. Open orifice in the nose, and the large intestine for the table, outside the skin and hair, and the natural world is closely linked, vulnerable to external aggression, and intolerance of natural cold, heat, dryness and dampness of the invasion of all evils, so the lungs for the "delicate viscera," as the name.

(A) the characteristics of lung lesions: from the internal medicine of Chinese medicine in the lung system of disease evidence is divided into a cold, cough, croup, wheezing, carbuncle, lung labor, lung distension, lung impotence, eight categories. In each category and according to the different symptoms, divided into various types of evidence.

Common symptoms are mainly cough, asthma, cough phlegm, chest pain, four main symptoms. Such as cough and dry cough and cough spit yellow, white, red thick or thin sputum. Wheezing, but also divided into solid wheezing and false wheezing and so on the difference.

(b) Lung pathology leads to the pathology of other organs and organs: for example, the lung opens the orifices in the nose, nasal pathology, nasal congestion, runny nose, sneezing, nasal abyss, epistaxis, etc. The lung is responsible for the skin and hair, and many skin diseases are related to lung pathology. The lungs are responsible for skin and hair, and many skin diseases are related to lung pathology, such as rubella, eczema, facial acne, etc. The lungs and the large intestine are the exterior and interior of the body. Lung and large intestine as the table, habitual constipation. The lungs regulate the water channels, and many edema diseases are cured by lung therapy.

Chinese medicine to the lung physiology and pathology of the understanding of both the modern medical physiological function of the respiratory system and pathological changes. Also includes digestion, five senses nose, skin, and heart, liver, spleen and kidney are closely related. People are organic whole, so the identification of lung disease, we must use a holistic concept, look ask smell cut diagnostic methods, pick up the eight outline of yin and yang, cold and heat, respectively, class evidence of the lung system of disease diagnosis and treatment, precise selection of drugs, in order to achieve the effect of the beam.

Imaging for Health, I'm Dr. Dahai, an imaging physician, and I'm happy to be here to answer your questions.

What is the reaction if there is a disease in the lungs? Here is an explanation with actual cases.

• Case 1

Male, 86 years old, primary causeDyspnea, cyanosis of the lipsHe is unable to sit upright in the clinic and reports no other significant symptoms. Chest CT presentation is shown below.

A large amount of fluid accumulated in the right thoracic cavity and the lung tissue was compressed to the hilum, causing severe pulmonary dysfunction and depriving the body of oxygen.

• Case 2

Male, 30 years old, primary causecough with sputumtrimestersputum with blood in itThree-day visit: Chest CT presentation is shown below:

Cavity formation and dissemination along the airways, which is the imaging manifestation of tuberculosis, and later sputum test positive for Mycobacterium tuberculosis, tuberculosis in addition to the above mentioned symptoms haveLow-grade fever, night sweats, and lethargy.

• Case 3

Female, 76 years old, primary causeHigh fever, chills, cough and sputumThe patient was seen and the chest CT presentation is shown below.

A large, dense shadow in the lower lobe of the left lung is a sign of pneumonia, which, in addition to the above symptoms, canChest pain, difficulty breathing.

• Case 4

Female, 73 years old, primary causechest tightness and shortness of breathThe patient was seen and the chest CT presentation is shown below.

Decreased density in both lungs and a barrel-shaped chest are signs of emphysema.

Combine these with a few actual cases that occur when there is disease in the lungs:Coughing and coughing up sputum, blood in sputum, hemoptysis, chest tightness and shortness of breath, dyspnea, chest pain, fever, chills, fatigue, and emaciation.Due to individual variability, the same lung disease may present different symptoms, and different lung diseases may present the same symptoms, which requires the clinician to confirm the diagnosis by combining relevant auxiliary examinations and clinical symptoms.

I am the imaging department doctor sea, regularly share health knowledge, like plus attention oh!

What is the reaction if you have a lung disease?

People are not unfamiliar with the new crown pneumonia, the new crown pneumonia is a kind of lung disease, the new crown pneumonia belongs to the viral infection, is a kind of lung infection, the main manifestations of a dry cough, fatigue, fever in severe cases can be shortness of breath, respiratory distress and even the emergence of multiple organ failure, such as the kidneys, the heart, the liver and so on.

Lung infection is only one type of lung disease, besides lung viral infection, there are also lung bacterial infection, mycoplasma infection, chlamydia infection, fungal infection, parasitic infection, asthma, tuberculosis, lung abscess, bronchodilatation, emphysema, chronic obstructive pulmonary disease, mantle bronchitis, cor pulmonale, pulmonary arterial hypertension, interstitial lung disease, pulmonary tuberculosis, pneumoconiosis and so on.

These lung diseases can present with one or more of these manifestations as follows.

Coughing up sputum, very common, cough can be irritating dry cough, episodic dry cough, high pitched and loud dry cough, no sputum or not much sputum and coughing up sputum, sputum can be yellow pus sputum, white frothy sputum, white mucus sputum, rusty sputum, jam-like sputum, coffee-colored sputum, pink frothy sputum.

Hemoptysis of varying severity, either intermittent or continuous or persistent blood in sputum, hemoptysis can also be seen.

Shortness of breath or even difficulty breathing, vague pain in the chest, dull pain in the chest, vague pain in the chest or mild or severe pain in the chest.

Wheezing sounds can be heard, such as in patients with bronchial asthma, chronic obstructive pulmonary disease, or lung cancer.

Cyanosis or cyanosis of the nail beds of the mouth and lips, heart failure due to lung disease can also cause bilateral lower extremity edema, jugular vein rages, and barrel chest can be seen in patients with chronic chronic obstructive pulmonary disease. If lung disease causes pneumothorax, tracheal displacement can be seen.

In addition, some patients with lung diseases can also develop drumstick fingers, called pestle fingers, which are most commonly seen in chronic lung abscess, pyothorax, bronchiectasis, lung cancer and other diseases.

As can be seen from the previous section, there are many lung diseases, in real life, the more common lung diseases include lung infections, chronic bronchitis, emphysema, chronic obstructive pulmonary disease, chronic pulmonary heart disease, bronchial asthma, lung cancer, pneumoconiosis, bronchiectasis, lung nodules, etc., mainly coughing and coughing up phlegm and wheezing and shortness of breath or even the emergence of, chest pain, blood in the sputum, dyspnea, cyanosis of lips and mouth and nail beds, double lower limb Edema and pestle finger and other manifestations, but specific to a lung disease, and have their own characteristics, such as mantle bronchitis is mainly manifested by repeated coughing and wheezing and even shortness of breath, and complications of lung infection can appear chills and fever, and lung cancer is mainly manifested by irritating dry cough, blood in the sputum, and the disease progresses wheezing, shortness of breath, chest pain and even dyspnea, emaciation and weight loss and other manifestations, and people are more familiar with new crown Pneumonia is to fatigue, fever, dry cough, severe patients with shortness of breath dyspnea and even multi-organ dysfunction, and bronchial asthma is in contact with cold air, allergens, physical and chemical factors stimulation, upper respiratory tract infections after coughing, wheezing chest tightness shortness of breath and even dyspnea, the sense of dying, often recurring episodes, so the lung disease specific to a particular disease have their own characteristics.

The lung is the main gas, the lung qi propagation and purging, can maintain the normal physiological function of the lung. Pathological changes in the lungs affecting the qi in and out of the Xuan-Di, will appear to cough, asthma-based respiratory system diseases.

1, lung gas deficiency: lung main gas, Division of respiration, lung gas deficiency is shortness of breath, coughing, lazy voice low, sputum more sparse, fear of cold sweating, easy to catch a cold.

2, lung yin deficiency: yin deficiency fire inflammation, lung loss of purging, then dry cough without phlegm or less phlegm, heat injury to the fluid is dry mouth and throat, throat itching mute, false fire forcing the leakage of Jin night sweating.

3, wind-cold bundle lungs: wind-cold bundle surface, the lungs are not declared, then cough sputum, nasal congestion and runny nose, shortness of breath. When wind-cold invades the surface of the muscles, there will be bad cold, fever, headache and body pain.

4. Wind-heat multiplying the lungs: if wind-heat offends the lungs or cold depresses the lungs and turns it into heat, there will be cough, yellow sputum, dry mouth and yellow urine. If heat injures the lung channels or blood heat is carried away, epistaxis or coughing up blood is the result.

5, dry heat injury to the lungs: fluid is burned, the lungs are not declared, then dry cough without sputum, dry nose and throat. Dryness injures the skin and hair, then fever, headache, body Chu.

6, phlegm obstruction of the lungs: phlegm obstruction in the lungs, lung qi can not be declared, then coughing, phlegm.

Lung main purging, adjusting the waterway, urinary fluency and often with the lung gas purging function. In addition, the lungs and is the organ of the voice, lung lesions, often affecting the voice changes, and even hoarseness, so that "the lungs main voice".

Lungs are one of the most important organs of the human body, with the environmental pollution coupled with smoking and other bad habits, resulting in the lungs have also become the most prone to various diseases. When the lungs do not appear a variety of diseases, the body will also appear a variety of corresponding reaction, then, specifically what reaction? Let's learn together.

First, let's understand the role of the lungs

The lungs are located in the chest cavity and are divided into the left and right lungs. The main physiological function is gas exchange, capable of exchanging oxygen from the air to the blood, and then expelling carbon dioxide from the blood through the body in the form of gas. The mucosal surface of the lungs is rich in immunoglobulins and immune cells, which together play a role in inhibiting pathogens entering the airways. The mucous membrane of the respiratory tract also secretes mucus, and through the constant movement of the cilia responsible for its surface, the harmful pathogens and dust in the airways are continuously expelled from the body in the form of phlegm, which forms coughing up phlegm. Therefore, the main physiological function of the lungs is to continuously inhale oxygen and expel the carbon dioxide produced by the body's metabolism at any time in order to maintain the normal life activities of the human body.

Why are the lungs susceptible to various germs?

Because the lungs through the trachea and the outside world the same, breathing air every moment contains bacteria, although most disease-causing pathogens are the body's nasal cavity, pharyngeal cavity to the filter, but there are still many pathogens with the air into the depths of the lungs, when the body's immunity is low will be infected with the cure.

What are the reactions that occur when there is a disease in the lungs?

1. CoughPeople with bad lungs are prone to cough symptoms, and the cough is more stubborn. Many people take cough medication directly to treat cough symptoms. For the cough that cannot be relieved repeatedly, it may be caused by certain lung tumors, and it is best to go to the hospital for appropriate examination. The first stage is an irritating dry cough, which leads to coughing up milky white mucus sputum or sputum with blood. Common symptoms of pneumonia are mainly manifested by coughing up mucus tenacious sputum or rust-colored sputum, or pus-like sputum, and the amount of sputum increases into the subsiding period, and the sputum is yellow and thinner.

2. blood transfusionPeople with bad lungs may have blood in sputum or even hemoptysis, such as bronchial dilatation, tuberculosis, lung cancer, etc., some patients will have varying degrees of hemoptysis, if you find the symptoms of hemoptysis, you must immediately seek medical attention, it may be caused by certain lung lesions, and it should not be taken lightly.

3. Chest tightness and shortness of breathIn fact, there are more causes of chest tightness and shortness of breath, the most common is lung disease, when feeling much less physical strength, a little exercise, climbing stairs, panting, coming up for air, indicating a decline in lung capacity, may be caused by bad lungs. Severe lung disease may cause dyspnea and require continuous oxygen intake.

4. Chest painLungs are located in the chest cavity, if there is a problem with the lungs, people will have chest pain symptoms appear. For example, tuberculous pleurisy, lung cancer, pneumonia, pneumothorax, pulmonary embolism, etc., may have varying degrees of chest pain. If you feel that the chest location is always hidden pain or stabbing pain, it is best to check immediately, it may be a problem with the lungs.

5. FeverIn the case of certain infections, such as pneumonia, tuberculosis, lung abscess, or fungal infection, patients also have fever. Patients with advanced lung cancer will have cancerous low-grade fever due to the increased metabolism of tumor cell necrosis.

6. Skin changesPeople with poor lungs have skin that is prone to dryness, roughness, dark spots, emaciated and dull face, flaky skin, enlarged pores, and burnt, lustreless hair. People with poor lung function will have cyanosis of the lips and mouth and blue skin.

7. Pestle FingerPeople with bad lungs grow thick, hammer-like fingers at the end, which is called pestle finger. This is called pestle finger. Pestle finger is an enlargement of the ends of the fingers or toes due to a lack of oxygen supply in the blood, which makes the ends of the fingers or toes thicken, hypertrophied and enlarged in a pestle shape. Among lung diseases, pestle finger is most common in lung tumors and chronic obstructive pulmonary disease.

How to Prevent Lung Disease

1. Cessation of smoking

Cigarettes are the most damaging thing to our lungs, and quitting smoking is essential to preventing lung disease.

2. Reduce occupational dust and chemical inhalation

(a) Labor protection should be provided to those who are exposed to occupational dust, such as workers in coal mines, metal mines, the cotton textile industry, the chemical industry and certain mechanical processes.

3. Reduce indoor air pollution

(a) Make every effort to avoid burning biofuels in poorly ventilated spaces, such as wood cooking, indoor heating, passive smoking, etc.; and

4. Actively prevent and treat upper respiratory tract infections

Spring is the high season of influenza, this time to pay attention to timely vaccination, avoid going to crowded places, keep the air in the room fresh, and actively treat upper respiratory tract infections.

5. Strengthening exercise

In normal times to actively participate in some physical exercise, each effectively improve the body's immunity, can timely prevent the occurrence of lung disease.

Finally summarize: when the lungs appear above all kinds of symptoms, you need to be alert to the possibility of lung disease, need to go to the hospital in time to do the appropriate examination, chest X-ray, lung CT, sputum culture, lung function and other tests can help diagnosis. Especially long-term smokers or people exposed to dust relief, it is more important to go to the hospital regularly for medical checkups to prevent the occurrence of lung diseases.

Lungs are our respiratory organs, which are connected to the outside world, but at the same time, they are also very delicate, as long as they are subjected to some injuries, there will be some obvious manifestations, and based on these manifestations, we can know whether the lungs are healthy or not. So, when the lungs have a disease, what will be the reaction?

First, cough or phlegm

When there is a disease in the lungs, the most obvious change is coughing or coughing up sputum, which is mainly due to inflammatory changes in the lungs, perhaps lung heat and lung dryness are too prevalent to easily stimulate the lung tissues and trachea bronchial tubes, which in turn causes irritating coughing in the lungs. Especially when there is an inflammatory infection in the lungs, which we often refer to as pneumonia, it is easy to produce phlegm, and through the action of coughing it is possible to cough up these inflammatory secretions from the lungs, which leads to coughing up phlegm.

So, when there is a disease in the lungs, it tends to produce coughing and sometimes even coughing up sputum. We can also initially determine what kind of disease it is by the color trait of the sputum, etc., such as coughing up rust-colored sputum, yellow sputum, green sputum, etc., and we can also use sputum culture to determine what kind of bacterial infection this is caused by.

Second, blood in sputum

Normally, even if a normal person coughs up sputum occasionally, the sputum will not have blood in it, and it is usually clear sputum. However, if there is blood in the sputum, then we should pay attention to the situation, which may be the lung tissue has been more serious lesions, invading the trachea bronchus and the blood vessels of the lungs capillaries.

If the situation of coughing up blood is a little more serious, then it may be a serious damage to the tissues, resulting in bleeding from small blood vessel damage in the lungs, such as lung cancer, tuberculosis, these diseases may be normal sputum with blood, or even coughing up blood. This kind of situation must be timely attention.

Third, shortness of breath, shortness of breath, chest tightness

Lungs are the main respiratory, the place where oxygen and carbon dioxide are exchanged. If there is damage to the lungs and there are certain serious diseases, the normal function of the lungs will be affected, and at this time it is easy to suffer from hypoxia, that is, we don't inhale enough oxygen, which causes us to suffer from shortness of breath, shortness of breath, and chest tightness.

This situation after we exercise a little, such as climbing stairs, climbing mountains, running, etc., will feel particularly insufficient gas than normal people, often climbing 2 or 3 floors of stairs will appear shortness of breath, shortness of breath, chest tightness. This is because the lungs can not travel the normal gas exchange, insufficient oxygen can only be obtained by speeding up the respiratory rate to get more oxygen, thus shortness of breath, shortness of breath, if the oxygen is not enough to provide the body's needs, it is easy to chest tightness. When the lack of oxygen is severe, even dyspnea may occur.

Fourth, chest pain

When chest pain occurs, it often indicates that the lung tissue has been seriously damaged, sometimes it is a vague pain, often in the form of pinprick pain, sometimes even radiating to the shoulder or abdomen, and this pain is worsened with coughing or deep breathing.

When chest pain occurs, you should pay attention to it, which may be caused by pleurisy or lung cancer.

In general, the lungs are a relatively delicate organ in our body, and there are many diseases in life that can cause changes in the lungs, through which we can detect certain lung diseases in time. For example, in this case of new crown pneumonia, many patients will have symptoms such as fatigue, dry cough, fever, etc. When these symptoms appear we should go to the hospital in time for relevant examinations, a clear diagnosis and early treatment.

How does a disease in the lungs react? The lungs are important organs in the human body, with two lungs, left and right. The oxygen that the body breathes in is exchanged through the alveoli, absorbing oxygen into the blood and expelling carbon dioxide. Therefore, once the lungs are not functioning well, conditions such as lack of oxygen will occur.

Diseases of the lungs include infectious lesions, neoplastic lesions and non-infectious neoplastic diseases. These include bacterial pneumonia, viral pneumonia, fungal pneumonia, bronchiectasis, lung cancer, misshapen tumors, tuberculosis, Langerhans' cytosis, and other diseases.

What happens when there is a problem with the lungs?

What is being talked about here would be what symptoms the body would have if there is a lesion in the lungs. In the case of small lesions, the body may not be able to feel them. Common symptoms of lung disease include the following.

1. Coughing up phlegm

Coughing up phlegm is the most common symptom of lung disease and can occur in almost all lung diseases. There is no specificity to this symptom, but coughing up sputum is the first thing to suspect that there may be a lung problem. If a young person has a cough for more than a month, a radiograph should be taken to rule out tuberculosis. If an elderly person has a prolonged cough and sputum, it is important to check for lung cancer. However, coughing up sputum is not necessarily caused by lung disease.

2. Hemoptysis, blood in sputum

Hemoptysis is the presence of blood in the sputum when coughing, not the blood vomited. Diseases that can cause hemoptysis include bronchiectasis, pulmonary embolism, tuberculosis, lung cancer, and so on. Many people are nervous when hemoptysis occurs, and this is when a CT of the chest is needed to rule out the above lesions. If there is no problem with the CT, it may be caused by coughing under the mucous membrane of the trachea, and if there is no problem with the CT, there is no problem with the lungs.

3.unable think calmly

Fever is a symptom of a respiratory infection, which includes lung disease. New Crown is a viral infection that can cause fever. Other bacterial, viral and fungal infections can also cause fever. Infections of organs throughout the body can cause fever, so the presence of fever does not necessarily mean that there is a problem with the lungs.

4.chest pain

Chest pain is also a symptom of lung disease and can manifest itself in rib fractures, pleural pulls, lung cancer, pneumonia, neuralgia, myocardial infarction, and more.

Today wrote about a slice of a 46 year old female that presented with having chest pain for a week, noticeable when breathing. the CT slice came out as a right rib fracture. She was asked if she had any trauma, if she had fallen and hit anything, and she said no. She may have touched something and not cared. She said no. She might have touched something but she did not care about it, but she did not know that she had fractured her rib. Generally speaking, rib fractures will heal with conservative treatment. If the dislocation is obvious, internal fixation is needed.

5.dyspnea

When dyspnea occurs, it means that there is not enough oxygen in the lungs and there may be hypoxia. For example, dyspnea may occur in the elderly with chronic obstructive pulmonary disease, pulmonary embolism, lung cancer causing metastasis and massive pleural effusion, massive pericardial effusion, and heart problems.

Care for your lungs, don't smoke

Smoking is harmful to health. People who smoke are prone to emphysema, a severe form of emphysema that can lead to respiratory failure. Smoking also tends to induce cancer. So, for your health and ours, care for your lungs and please do not smoke.

First of all the human lungs are the main purification of gases and provide oxygen to all parts of the body, and there are many lung diseases, such as bacterial infections, viral infections, parasitic infections, etc., and they can lead to the emergence of pneumonia, tuberculosis, lung abscess, lung cancer, asthma, chronic bronchitis, pulmonary heart disease and other diseases.

Below, Dr. Ma answers the question of what kind of reaction can occur when there is a disease in the lungs.

1. Cough

Cough which is a common symptom of lung diseases, mainly due to bacterial infection, tumor stimulation, allergic substances and other stimulation of bronchial tubes, resulting in spasm, so there will be coughing symptoms, coughing is obvious in some lung diseases, while some diseases are not obvious, especially below the lung segment of the tumor cough is less obvious.

2. Coughing up sputum

Coughing up sputum which is also a common symptom of lung diseases, mainly due to various factors leading to lung infections, so there will be some purulent secretions produced, which means that the common symptom is a cough accompanied by coughing up sputum.

3, Coughing up blood

Coughing up blood and sputum with blood is the most common symptom of lung cancer, but some lung inflammation leads to violent coughing and there will be some blood, mainly because coughing leads to bronchial capillary rupture and bleeding, so the symptom of coughing up blood needs to consult the doctor in time.

4. Chest pain

Everyone has felt the feeling of chest pain caused by coughing, because the most common symptom of respiratory tract infection and lung disease is coughing and coughing up phlegm, and too much phlegm can not be coughed up is going to appear chest tightness, and severe coughing chest pain, but lung cancer can also lead to the feeling of chest pain.
