What causes gastric mucosal shedding?

Under normal circumstances, gastric mucosal shedding may be caused by various factors such as aging, stress response, Helicobacter pylori infection, acute gastritis, and autoimmune gastritis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician.

1. Aging

As people age, the regenerative capacity of the gastric mucosa gradually declines, which may lead to increased susceptibility to damage and shedding of the gastric mucosa. Maintaining a healthy lifestyle—such as quitting smoking, limiting alcohol consumption, eating regular meals, and avoiding excessive fatigue—can reduce the risk of gastric mucosal injury.

2. Stress Response

During periods of stress, increased levels of stress hormones such as adrenaline and cortisol are released in the body. These hormones can suppress blood flow to the gastric mucosa, leading to ischemia and malnutrition of the mucosal tissue, thereby causing gastric mucosal shedding. Learning to manage stress through relaxation techniques like deep breathing and yoga is beneficial.

3. Helicobacter pylori Infection

Helicobacter pylori infection primarily occurs in individuals with weakened immune systems. The bacteria colonize the gastric mucosa and produce toxins that disrupt its normal structure and function, resulting in mucosal damage and shedding. Symptoms may include stomach pain and bloating. Under medical supervision, patients may be treated with medications such as omeprazole enteric-coated capsules, lansoprazole enteric-coated tablets, and bismuth potassium citrate capsules.

4. Acute Gastritis

Acute gastritis may be triggered by factors such as medication use or stress. The gastric mucosa becomes inflamed due to irritation from bacteria, viruses, or chemical substances, leading to local tissue damage and mucosal shedding. This condition is often accompanied by symptoms such as vomiting and loss of appetite. Patients are advised to take medications such as hydrotalcite tablets, sucralfate chewable tablets, or domperidone tablets under the guidance of a healthcare professional to alleviate symptoms.

5. Autoimmune Gastritis

Autoimmune gastritis is a type of gastritis caused by an abnormal immune response, in which the body produces antibodies targeting gastric parietal cells. These antibodies bind to the cells, damaging the gastric mucosa and causing it to shed. Symptoms may include anemia and weight loss. Under a doctor's instructions, patients may take medications such as metronidazole tablets, mosapride citrate tablets, or clarithromycin capsules to relieve symptoms.

In daily life, maintain a light diet, avoid spicy and irritating foods, and engage in appropriate physical exercise.
