Elderly people with severe cases of epigastric diarrhea mainly because he is prone to the following complications: 1. Acute viral myocarditis: medically called viral myocarditis, is one of the most dangerous complications of epigastric diarrhea. Some of the vomiting and diarrhea can be caused by viruses, the most commonly caused myocarditis virus is the coxsackievirus enterovirus, which can directly enter the myocardial cells causing damage, but also can cause the body to produce certain harmful substances, such as damage to the myocardial cells leading to myocardial degeneration, but also involving the pericardium, endocarditis, if the invasion of the heart pacing system is life-threatening; 2, cerebrovascular accident is also caused by acute vomiting and diarrhea in the elderly can not be neglected Complications, because vomiting and diarrhea make a large amount of water and sodium, potassium, calcium, magnesium and other cations in the body from the stool, water loss makes the body in a dehydrated state, so that the blood volume is reduced, blood viscosity increased, blood slow, easy to form thrombosis and block the blood vessels, so that the coronary artery blockage caused by angina pectoris and myocardial infarction. Cerebrovascular obstruction caused by ischemic stroke, sodium, potassium, calcium, magnesium is an important cation in the body, in addition to maintaining the blood acid-base balance, to maintain nerve conduction function and heartbeat rhythm, has a pivotal role, the lack of serious heart rhythm disorders and sudden death; 3, hypoglycemia vomiting and diarrhea appetite often decline, will also be prone to hypoglycemic reaction, when the body needs to break down the liver glycogen stored to When the blood sugar decreases, the elderly will easily experience a series of symptoms of hypoglycemia, such as fatigue, sweating, palpitations, pallor and fainting. Normal blood glucose concentration is 3.9-6.2mmol/L, when blood glucose concentration is lower than 3mmol/L, mental symptoms will appear and even coma will cause sudden death, so hypoglycemia is also a serious complication caused by vomiting and diarrhea; 4. Dehydration and acidosis are also the main causative factors of acute vomiting and diarrhea, usually carbon dioxide produced by metabolism in the body is discharged through breathing, and the rest of the waste needs to be In case of dehydration, the amount of urine is reduced due to water loss in the body, and in severe cases, there is even no urine, which reduces the discharge of metabolic wastes in the body and causes the accumulation of toxic symptoms in the body, whose clinical manifestations, in addition to respiratory changes, can also show fatigue and weakness and neurological symptoms; 5. Recurrent recurrence of gastric disease: the digestive function of the body is also reduced after vomiting and diarrhea. The intestinal antiviral ability also decreases, making the gastrointestinal function more burdened, which can lead to recurrence of gastrointestinal disease. These are the common acute vomiting and diarrhea brought about by the very serious hazards.
