The phenomenon of smelly fart and sticky stool is mainly related to the influence of diet, functional diseases and organic lesions of the digestive system. 1. Dietary influences: Consuming more gas-producing, indigestible and stimulating foods, such as cabbage, sweet potatoes, soy products and chili peppers, etc., can lead to an increase in gastrointestinal gases, which can stimulate the secretion of gastric acid and lead to the emergence of farting odor and sticky stools. 2. Functional diseases: such as functional dyspepsia, which can lead to early satiety, bloating, frequent farting, smelly farts and sticky stools. 3. Organic lesions of the digestive system: such as chronic gastritis, gastric ulcer and other diseases, will affect the gastrointestinal function, and trigger nausea, belching, acid reflux, farting is very smelly and stools are sticky and so on. The long-term occurrence of such symptoms should cause the patient’s attention, as soon as possible to consult a doctor for examination to confirm the cause of the disease, and under the guidance of the doctor for treatment.
