What causes frequent passing of foul-smelling gas?

Generally, passing foul-smelling gas refers to the discharge of malodorous intestinal gas. Frequent passage of foul-smelling gas may be caused by a high-protein diet, poor eating habits, constipation, intestinal flora imbalance, chronic enteritis, or other reasons. If the above conditions occur, it is recommended to seek timely medical treatment. A detailed analysis is as follows:

1. High-Protein Diet

Consuming high-protein foods frequently, such as meat, fish, and legumes, can lead to the production of sulfur- and nitrogen-containing gases like hydrogen sulfide and ammonia when these foods are broken down by intestinal bacteria. These gases have a strong odor and can cause frequent passage of foul-smelling gas. It is advisable to maintain adequate water intake in daily life to promote intestinal motility.

2. Poor Eating Habits

Long-term irregular eating habits, eating too quickly, and talking while eating can cause excessive air to be swallowed into the intestines. When this air mixes with intestinal gases and is expelled, it results in foul-smelling gas that persists for a long time. It is important to improve eating habits in daily life, such as chewing food thoroughly and avoiding talking while eating.

3. Constipation

Improper diet, indigestion, intestinal obstruction, and other factors can trigger constipation. Long-term constipation can cause fecal matter to remain in the intestines for extended periods, during which bacteria break down the feces and produce large amounts of malodorous gases such as ammonia, leading to the aforementioned symptoms. Symptoms may include difficulty with bowel movements and dry, hard stools. Treatment may require following medical advice to use medications such as smectite powder, loperamide hydrochloride capsules, and trimebutine maleate tablets.

4. Imbalance of Intestinal Flora

Intestinal flora imbalance may be related to dietary changes, alterations in microbial populations, and drug metabolism. If the intestinal flora is frequently imbalanced, it may lead to dysbiosis, increasing harmful bacteria that inhibit digestive function and produce excessive gas, resulting in the problem of foul-smelling gas. Symptoms may include indigestion and abdominal pain. Patients should follow medical advice to use medications such as Bifidobacterium quadruple viable tablets, Bacillus licheniformis viable capsules, and compound lactobacillus acidophilus enteric-coated capsules.

5. Chronic Enteritis

Diet, infections, immune system issues, and other factors may trigger chronic enteritis. Chronic enteritis causes long-term inflammation of the intestinal mucosa, affecting the digestion and absorption of food, leading to fermentation of food residue in the intestines and the production of foul-smelling gas. Symptoms may include diarrhea and abdominal pain. Treatment should be guided by a physician using medications such as amoxicillin capsules, cefuroxime axetil tablets, and Bifidobacterium triple viable capsules.

In daily life, it is important to maintain a balanced diet and consume more fiber-rich foods to promote intestinal motility. Developing good eating habits, avoiding eating too quickly, and refraining from talking while eating can help maintain intestinal health and reduce the occurrence of foul-smelling gas.
