Patients with ketoacidosis initially present with generalized weakness, loss of appetite . Nausea, vomiting, and also other symptoms such as cool stomach. Patients can also have fever, severe thirst, particularly increased urination, mental depression, and even. Dry skin, dry lips, and deep eye sockets are caused by the patient's reduced intake of food and water, as well as accelerated respiration due to acidosis and infection, leading to severe water loss in the body. Patients with severe ketoacidosis also have a ketone odor (i.e. rotten apple smell) in their breath. Because the patient's blood sugar is high and urine output increases, sugar is bound to bring out a large amount of water when it is excreted from the urine, so severe dehydration and hypovolemia can occur. And because the ketone body is acidic, can cause vasodilation, so further aggravate the reduction of blood volume, blood pressure reduction, serious cases can occur shock . Blood pressure cannot be measured. In addition, a large number of acidic ketone bodies can also destroy the patient's internal environment, resulting in cardiac failure, renal failure, cerebral cell edema and so on. All these seriously threaten the patient's life. Since ketoacidosis is a fatal and dangerous complication, the success of its rescue depends on whether it can be diagnosed and treated in time. Therefore, once a patient develops the above symptoms, he or she should be sent to the emergency room of a hospital immediately for examination and treatment. Family members are advised to bring along the patient's previous medical records, as well as various examination reports. For example, blood sugar, electrocardiogram, etc., and tell the doctor in time.
