Farting very hot may be a normal phenomenon, or it may be due to gastrointestinal dysfunction, acute gastroenteritis, ulcerative colitis, anal lesions and other reasons. 1. Normal people’s intestinal temperature is higher than the body surface temperature, feces in the intestinal lumen formation and discharge process to absorb the heat of the intestinal wall, so it will feel farting very hot. 2. Gastrointestinal dysfunction: prolonged overeating, eating spicy stimulating food, cold abdomen and other factors lead to gastrointestinal peristalsis, food stagnation in the intestinal cavity for a long time, so farting is very hot. 3. Acute gastroenteritis: Bacteria, viruses and other pathogenic microorganisms infecting the intestinal tract cause inflammatory lesions of the intestinal wall, resulting in inflammatory changes such as redness, swelling, heat and pain in the intestinal lumen, so farting is very hot, accompanied by diarrhea, nausea, vomiting, abdominal pain and other symptoms. 4. Ulcerative colitis: non-specific inflammatory lesions in the intestinal tract due to autoimmune abnormalities and other factors, resulting in exudation, ulceration, bleeding of the intestinal wall, so it will fart very hot. 5. Anal lesions: inflammatory lesions in the anal area, hemorrhoids, anal fissures, etc. lead to an increase in the local temperature of the anus, so farting feels hot. Farting very hot may be related to a variety of factors, it is recommended to consult a doctor for a clear diagnosis.
