Possible causes of strong intestinal flatulence after meals include gastritis, indigestion, etc., which need to be dealt with according to the cause, and the general treatment includes the use of acid-suppressing drugs, gastric power-promoting drugs and other medications. 1. Gastritis: This includes acute and chronic gastritis and other diseases caused by various reasons, such as Helicobacter pylori infection, long-term alcohol consumption, autoimmune factors, etc., which cause flatulence after meals. If the infection is caused by Helicobacter pylori, it can generally be treated with medications such as omeprazole, bismuth potassium citrate and clarithromycin. 2. Dyspepsia: Possible triggers of dyspepsia include irregular meals, inappropriate dietary behaviors such as consuming too many sweets or fats, and mental stress, etc. The main symptom is a feeling of fullness and bloating after meals. Gastric stimulants such as domperidone can be used to promote gastrointestinal motility. In addition, you need to eat regularly and participate in more exercise. 3. Imbalance of intestinal flora: Possible causes include long-term use of antibiotics, immune factors, intestinal inflammation and so on. Due to the imbalance of intestinal flora, there may be an increase in intestinal gas production, resulting in intestinal flatulence after meals. Therefore, reasonable use of antibiotics is needed, and ecological agents such as bifidobacteria and lactobacillus can be used to regulate the intestinal flora. When intestinal flatulence occurs after meals, it is recommended to go to a regular hospital in time to find out the cause and actively treat it.
