Always farting at night may be caused by physiological reasons such as eating too much before going to bed, or it may be caused by gastroenteritis, duodenal ulcer and other pathological factors. 1. Physiological factors: overeating before going to bed, eating too fast, consuming gas-producing foods such as groundnuts, onions, cabbage, soy milk, or consuming stimulating foods such as spicy hot pot, pot chicken, barbecue, alcohol, fried chicken, ice cream and other stimulating foods, which aggravate the burden on the gastrointestinal tract and cause bloating, farting and other indigestion manifestations. 2. Pathological factors: such as chronic gastritis, gastric ulcer, duodenal ulcer, ulcerative colitis, Crohn’s disease, intestinal tuberculosis and other diseases, bacterial, fungal, viral and other factors cause gastrointestinal congestion, edema, erosion and other symptoms, resulting in gastrointestinal digestive and absorptive functions, leading to dyspepsia and other symptoms, such as nausea, vomiting, abdominal distension, diarrhea, abdominal pain and other systemic symptoms such as emaciation. Farting at night is always recommended to consult a doctor to clarify the diagnosis, under the guidance of the doctor for targeted treatment.
