Introduction
In general, common causes of frequent flatulence include improper diet, excessive air swallowing, functional dyspepsia, irritable bowel syndrome, and ulcerative colitis. If discomfort symptoms occur, it is recommended to seek timely medical consultation and treatment at a正规 hospital. In daily life, one should develop good eating habits, chew food thoroughly and eat slowly, reduce intake of gas-producing foods, and avoid carbonated beverages.
Generally, the main causes of frequent flatulence include improper diet, excessive swallowing of air, functional dyspepsia, irritable bowel syndrome, and ulcerative colitis. If discomfort occurs, it is recommended to seek timely diagnosis and treatment at a正规 hospital. Detailed analysis is as follows:
1. Improper Diet
Consuming excessive gas-producing foods such as legumes, onions, and sweet potatoes may lead to increased gas production in the intestines due to fermentation, resulting in frequent flatulence. Adjust the diet by reducing gas-producing foods and increasing dietary fiber intake such as vegetables and fruits. Maintain regular eating habits and avoid overeating.
2. Excessive Air Swallowing
Eating too quickly, frequent gum chewing, or drinking carbonated beverages may cause excessive air to be swallowed into the intestines, leading to increased flatulence. Slow down while eating, chew food thoroughly, reduce gum and carbonated beverage consumption, and take a light walk after meals to aid gas expulsion.
3. Functional Dyspepsia
Slowed gastrointestinal motility can hinder digestion and absorption of food, causing it to remain in the intestines for extended periods, ferment, and produce gas, resulting in frequent flatulence accompanied by bloating and post-meal fullness. Under a doctor's guidance, medications such as domperidone tablets, lactase tablets, or compound digestive enzyme capsules may be taken. Engage in light physical activity after meals and avoid prolonged sitting.
4. Irritable Bowel Syndrome
Intestinal dysfunction and heightened sensitivity to food and gas may lead to bloating and frequent flatulence, often accompanied by abdominal pain and altered bowel habits. Under medical guidance, medications such as pinaverium bromide tablets, Bifidobacterium quadruple viable tablets, or trimebutine maleate tablets may be taken. Avoid spicy and irritating foods and maintain emotional stability.
5. Ulcerative Colitis
Ulcerative colitis affects digestive function, causing incomplete digestion and gas production through fermentation, leading to frequent flatulence accompanied by diarrhea, abdominal pain, and mucus in the stool. Under a doctor's supervision, medications such as mesalazine enteric-coated tablets, sulfasalazine enteric-coated tablets, or prednisolone tablets may be taken. In severe cases, surgical removal of the affected intestinal segment may be required, followed by a postoperative diet consisting of easily digestible and bland foods.
In daily life, develop good eating habits, chew food thoroughly, reduce gas-producing foods, avoid carbonated beverages, maintain a cheerful mood, avoid anxiety and stress, and undergo regular physical checkups to detect intestinal issues early.
