The actual fart with thin yellow watery stool may be caused by acute gastroenteritis and hemorrhoids, which need to be clarified for specific reasons and then targeted treatment. 1. Acute gastroenteritis: Patients may have acute gastroenteritis after unclean food, intestinal infection and cold. The performance is mainly nausea, vomiting, abdominal pain, diarrhea, fever, etc., which may lead to farting with thin yellow stools. You can adjust your diet, and add antibiotics and flora regulators such as gentamicin and safranin if the symptoms are severe, or use montelukast to stop the diarrhea and improve the symptoms. If the effect of treatment is not good, it is necessary to consider the possibility of combining other underlying diseases, and the diagnosis can be clarified by colonoscopy and CT examination. After the diagnosis is confirmed, further treatment will be given for the cause. If there is a surgical disease, surgical treatment is required. 2. Hemorrhoids: Patients with hemorrhoids may have perianal congestion, edema or anal fissures, which may lead to thin yellow stools when farting. Conservative treatment options include dietary interventions, such as increasing fiber intake and drinking more water, and medication can be given through internal and external use of Chinese herbs and medicated sitz baths, such as six-flavored hemorrhoid elimination tablets, etc. If conservative treatment is not effective, surgical treatments can be taken, such as hemorrhoidectomy and thrombosed external hemorrhoid removal. For thin yellow stool when farting, Chinese medicine considers it as a loss of spleen health and phlegm-dampness obstruction, so you can take Ginseng and Atractylodes pellets to strengthen the spleen and dampness, Tonic Zhong Yi Qi Pills to strengthen the spleen and benefit the qi, and moxibustion points such as Shen Que, Shui Shui, Jian Li and Foot San Li to strengthen the spleen and dampness. On weekdays, you should eat a light diet, avoid spicy, greasy, cold and rough things, and exercise appropriately to enhance your physical fitness.
