Chronic gastritis can cause dysfunction of the gastrointestinal tract, leading to bad breath. Additionally, it can manifest symptoms of indigestion such as pain and acid reflux in the upper abdomen, and decreased appetite. Atrophic gastritis may present with anemia and diarrhea. The primary treatment principles for chronic gastritis should focus on eliminating the cause, reducing recurrence of inflammation, and improving the patient's quality of life. Medications that inhibit gastric acid secretion, protect the gastric mucosa, and promote gastrointestinal motility are used for treatment.

How to treat dry heaving in chronic gastritis?

Patients with chronic gastritis who experience dry retching should consider whether it is due to insufficient gastrointestinal motility or excessive secretion of gastric acid. It is recommended to avoid overly spicy and irritating foods, eat regularly and in proper amounts, and maintain a pleasant mood without being disturbed by anxiety, sadness, and anger. Eating more fresh vegetables and fruits rich in vitamins is also advisable. At the same time, try to avoid using drugs that damage the gastric mucosa, such as hormones, antirheumatics, and non-steroidal anti-inflammatory drugs, etc.

Does chronic gastritis cause nausea?

Chronic gastritis generally does not manifest with nausea; the main symptoms are indigestion, such as decreased appetite, acid reflux, and pain in the upper abdomen. Chronic atrophic gastritis may also present with anemia and diarrhea. More severe cases can lead to vomiting blood and black stools. The primary causes are directly related to Helicobacter pylori infection and chronic damage to the gastric mucosa. Treatment mainly involves protecting the gastric mucosa, suppressing gastric acid secretion, and eradicating Helicobacter pylori infection.

Does chronic gastritis require medication?

Chronic gastritis often has no clinical symptoms, but this condition still requires medication treatment. The duration of medication must be long-term and regular, primarily focusing on drugs that suppress gastric acid secretion and protect the gastric mucosa. If the inflammation is relatively significant, antibiotics can be chosen; in cases of Helicobacter pylori infection, a triple therapy, which includes two antibiotics and a gastric mucosa protective agent, can be opted for. Additionally, it is crucial to pay attention to daily life routines, eat a light diet, avoid raw, greasy, and fried foods, and rest well to gradually recover from gastritis.

What should I do if chronic gastritis flares up?

If chronic gastritis flares up, patients need not be overly anxious. Standard treatment can quickly cure chronic gastritis. Following an acute flare-up of chronic gastritis, the first step involves using medications such as magnesium carbonate, aluminum sucrose sulfate, and aluminum-magnesium suspension to protect the gastric mucosa. Then, use H2 receptor antagonists or proton pump inhibitors to suppress stomach acid secretion and increase the pH level inside the stomach. Sometimes, traditional Chinese medicine is also quite effective in treating chronic gastritis, such as Qi Stagnation Stomach Pain Granules, Wen-Wei Shu, Yang Wei Shu Capsules, and Xiang Sha Yang Wei Pills. (Please use medication under the guidance of a doctor.)

What should someone with chronic gastritis eat normally?

For patients with chronic gastritis, we recommend avoiding irritant foods and opting for foods that cause less irritation to the stomach. Avoid overly acidic or sweet foods. It is suggested that patients keep foods like steamed buns and soda crackers, which are alkaline, on hand. Try to avoid consumption of raw, cold, hard, or hot foods, as well as tea, coffee, and substances like tobacco and alcohol, which are highly irritating to the stomach.
