Smelly farts may be related to improper diet, constipation, intestinal diseases and other factors. 1. Improper diet: If you eat too much gas-producing food, such as sweet potatoes, onions, etc., it may lead to the production of hydrogen sulfide, ammonia and other components in large quantities, resulting in farting and particularly smelly phenomenon. 2. Constipation: When the patient is constipated, it will be easy for the stool to be unable to be discharged from the body in time, and it will accumulate in the intestines and continue to be absorbed, resulting in abnormally dry stools, which will easily breed bacteria and make farting too smelly. 3. Intestinal diseases: If the patient suffers from ulcerative colitis, chronic enteritis and other diseases, it may lead to damage to the intestinal mucosa, affecting the intestinal digestion and absorption function, resulting in the accumulation of food in the intestines, unable to ferment, farting too smelly. When farting is too smelly, you should pay attention to your diet and eat less food that produces gas easily. If it is caused by a disease, you should go to the hospital in time, after clarifying the cause of the disease and actively treat it, so as not to delay the condition.
