Bad bowel farts may be caused by eating too much meat recently, or it may be caused by gastrointestinal dysfunction, or it may be caused by bowel cancer. It can be regulated by diet or medication. 1. Physiological factors: if you have recently consumed too much fat and protein, it can lead to intestinal flora imbalance, which makes the intestinal bacteria decompose a lot of food that the human body fails to digest and absorb, and then there are the symptoms of gastrointestinal fart, you can take probiotic preparation, such as bifidobacteria, lactobacillus tablets, etc., or improve the dietary structure, eat more vegetables and fruits and consume meat food in moderation. 2. Gastrointestinal dysfunction: Gastrointestinal dysfunction can lead to food not being able to be digested adequately, which in turn leads to the symptom of bad stomach and farting, and can be treated with medicines such as mosapride and domperidone. 3. Bowel cancer: Bowel cancer can cause patients to suffer from constipation, which makes food residues stay in the intestine for too long, thus leading to the symptoms of bad bowel and excessive farting. The treatment should be mainly based on surgery, combined with chemotherapy, targeted therapy and radiotherapy to carry out comprehensive treatment. After eliminating the physiological factors, if the symptoms of bad stomach and farts continue to be unrelieved, it is recommended to consult a doctor in time to find out the cause and ask the doctor to deal with it.
