Simple flatulence does not usually lead to weight gain, but it may lead to weight gain if the flatulence is accompanied by a buildup of food that cannot be easily expelled. Gastrointestinal flatulence is usually associated with indigestion. When there is an increase in gas in the intestines, it affects intestinal digestion and tends to form gastrointestinal flatulence, but in the absence of a buildup of food, it does not usually lead to weight gain. If the gastrointestinal flatulence affects the normal passage of food and keeps accumulating in the intestines and cannot be discharged in time, it may lead to weight gain. However, when the intestines are properly ventilated, weight loss will occur naturally and is not an obesity weight gain. Whether weight gain from bloating should be analyzed in the context of one’s own situation. If long-term bloating and indigestion make it impossible to eat normally, it is necessary to consult a doctor in time and analyze the cause of the disease under the guidance of a professional physician.
