Not necessarily. The typical symptom of asthma is episodes of expiratory dyspnea with rales. However, there are a number of clinical conditions that are similar to asthma exacerbations, the most common being dyspnea due to left heart failure, this is particularly similar but treatment focuses on improving cardiac function. Others are chronic obstructive pulmonary disease, upper airway obstruction (foreign bodies, bronchial stenosis due to lung cancer), allergic bronchopulmonary aspergillosis, and others.

There are also asthma that manifests itself only as a cough; asthma with only symptoms of chest tightness; asthma that flares up during exercise; and asthma caused by taking aspirin.

It is not possible to say that you have asthma just because you have the typical characteristics of croup.

Asthma is an allergic disease. The full name of asthma is actually bronchial asthma. Bronchial asthma is one of the more complex diseases. This chronic disease is very likely to make the patient airway plateau reaction, airway plateau reaction is characterized by: sharp wheezing, chest tightness, dry cough, and plateau airway hypersensitivity reaction appeared in the cough is often in the early morning or in the middle of the night the patient syndrome sleepy time period. Bronchial asthma is not serious patients can generally be cured on their own.

Bronchial asthma can recur at certain times, such as the change of seasons or when the cold air comes down from the south. If the patient is in the stage of bronchial asthma attack, then there will be: chest tightness, dyspnea, shortness of breath, dry cough. In fact, bronchial asthma is not completely without signs in the pre-exacerbation phase, the pre-exacerbation signs include: cold symptoms and red and itchy eyes. The duration of an attack can be as short as a few minutes or as gradual as a few days, it is not certain. The only thing that is certain is that a severe bronchial asthma attack can be life threatening, with severe symptoms of breathlessness and hypoxia.

Bronchial asthma is divided into three phases according to the severity of its onset: acute exacerbation, chronic persistence, and clinical remission; and three levels according to the severity of the exacerbation: grading of severity, grading of level of control, and grading of severity of the acute exacerbation.

Asthma is a serious global disease that affects people of all ages and in all countries of the world. The prevalence of asthma is increasing in most countries, especially in the pediatric population. Although hospitalization and mortality rates for asthmatics have declined in some countries, asthma continues to be a burden on health care systems and reduces social productivity, especially in children, and the impact on families can be devastating.

According to the latest medical guidelines, a diagnosis of asthma needs to be supported by evidence in the following areas:

1 Past and family history

Having respiratory symptoms during childhood, having previous allergic rhinitis or eczema, or a previous family history of asthma or allergies increases the likelihood of asthma.

2 Physical Examination

A routine physical examination should be performed on patients with asthma, a particularly unique physical characteristic of asthma.

3 Pulmonary function demonstrates reversible expiratory airflow limitation

Asthma is characterized by reversible restriction of expiratory airflow and changes in expiratory lung function over time and to a greater extent than in healthy individuals. With asthma, lung function varies between completely normal and severely obstructed in the same patients. Poorly controlled asthma showed a greater degree of change in lung function than well-controlled asthma.

4 Other inspections

4.1 Bronchial excitation test

In some patients, airflow limitation may be absent from the initial evaluation. Variable airflow limitation is a key component in establishing the diagnosis of asthma, one of which is the bronchial provocation test, which evaluates airway hyperresponsiveness

4.2 Allergenicity tests

The presence of allergies increases the likelihood that patients with respiratory symptoms will develop allergic asthma, but is not asthma-specific nor present in all phenotypes of asthma.

4.3 Exhaled gas nitric oxide

Nitric oxide exhalation in eosinophilic asthma while in nonallergic conditions (e.g., eosinophilic bronchitis and allergic rhinitis) and is not considered a useful diagnosis for asthma.

Therefore, asthma cannot be diagnosed by symptoms alone, but requires a combination of many test results and the exclusion of other diseases before a clinical diagnosis of asthma can be made.

A relative of mine used to 🈶️ have asthma, and then heard 🉑️ that it could be an allergic reaction, and needed to go to the hospital to see what caused the asthma. I realized that it was due to pork allergy, since then 2⃣️0 years do not eat pork, never asthma. (For reference only, each person's situation is different)
