At present, domestic and foreign treatment of hepatitis B does not have a drug special drug, the traditional injection, oral drugs can only inhibit the replication of the virus, can not be completely cured. Chen has been suffering from hepatitis B for more than a year, and after treatment with Chinese and Western drugs, he has three positive hepatitis B “two pairs of half” surface antigen (HBsAg), e antibody (HBeAb), core antibody (HBcAb), which is commonly known as “small triplet”, and normal liver function, but still The three positives of HBeAb, HBcAb, and HBcAb are commonly known as “small triple-positive”. Xiao Chen did not pay attention to it and thought it was still a symptom of hepatitis. Once, Chen’s symptoms worsened and he had to go to the doctor. The doctor suggested a gastroscopy. As a result, the gastroscopy diagnosed chronic superficial gastritis. Xiao Chen did not understand why having hepatitis B would cause chronic gastritis? The doctor explained that it was due to damage to the gastric mucosa caused by the hepatitis B virus, which is a generalized virus that invades the gastric mucosa as its common extrahepatic damage in addition to the liver. The incidence of hepatitis B complicating gastric mucosal damage is as high as 100%. The mucosal lesions are diffuse and extensive, mainly in the fundus and body of the stomach. The incidence of hepatitis B combined with chronic gastritis is 70% to 80%. The incidence of combined peptic ulcer disease is about 30%. The presence of hepatitis B virus in the epithelial cells of the gastric mucosa causes an inflammatory response due to the deposition of hepatitis B antigen-antibody immune complexes in the cells, thus weakening and destroying the barrier protection of the gastric mucosa. With hepatitis B, the dysfunction of gastric acid formation is disturbed, resulting in excessive gastric acid, which damages the gastric mucosa and is associated with the development of gastric feeder ulcers. Immune dysfunction, which produces autoimmune response, leads to damage of gastric mucosa. Impaired liver function decreases the inactivation of hormones by the liver and reduces the amount of albumin, which weakens the ability to repair the gastric mucosa. Caused by drug stimulation. Patients with hepatitis B, especially those with chronic hepatitis B, need to take medication for a longer period of time. Patients are eager to heal, often taking too many types of drugs, or several drugs at the same time, ignoring the interaction between drugs can produce stimulation of the gastric mucosa. Some drugs themselves have an irritating effect on the gastric mucosa, especially some bitter-cold herbs that have a certain irritating effect on the stomach. Some chronic hepatitis B patients have varying degrees of cirrhosis and portal hypertension, which slow down gastric blood flow and cause damage to the gastric mucosa due to ischemia, hypoxia and nutritional disorders. When patients with hepatitis B have gastrointestinal symptoms, such as upper abdominal discomfort, vague pain in the middle and upper abdomen, bloating, acid reflux, poor nausea, nausea and vomiting, they are often mistaken for symptoms of hepatitis itself, which should be noticed and gastroscopy should be done promptly to clarify whether they are accompanied by gastric mucosal damage. Hepatitis B patients, in the treatment of liver disease when taking hepatoprotective drugs, we should try to avoid taking drugs that irritate and damage the gastric mucosa, according to the condition, disease duration, age and gastroscopy observation results, consider the use of metformin (cimetidine), aluminum thioglycollate, gentamicin and digestive aid drugs taken orally, so as to improve the patient’s digestive function, reduce or subside the symptoms of the digestive tract. Pure Chinese medicine Gastric Su Punch has good effect on gastric mucous membrane damage caused by chronic hepatitis B. It can inhibit gastric acid secretion, reduce gastric enzyme activity and enhance gastric peristalsis, which has obvious protective effect on gastric mucous membrane. At the same time, avoiding the stimulation of spicy food in the diet and quitting smoking and drinking will be beneficial to the protection of liver and stomach. The above is the introduction of the symptoms of hepatitis B. I believe that you have understood the symptoms of hepatitis B, and should do a good job of prevention and care measures in daily life to stay away from the disease.
