Loud farting may be caused by physiological situation, or it may be caused by eating more gas-producing food, intestinal flora imbalance and so on. 1. Physiological situation: when people are talking or eating, they may swallow some gases, and these gases, along with the peristaltic movement of the gastrointestinal tract, may reach the anus area, and then farting loudly occurs. 2. Eating more gas-producing foods: Some foods, such as soybeans, pumpkins, sweet potatoes, etc., enter the gastrointestinal tract and can be broken down to produce more gas. If you eat more gas-producing food frequently, you may have loud farts. 3. Intestinal flora imbalance: Bacteria in the intestinal tract are divided into three categories, namely, probiotics, harmful bacteria and commensal bacteria. Harmful bacteria may produce a lot of gas when they decompose food. If the content of probiotics decreases and the content of harmful bacteria increases, it may lead to loud farts. Patients who have a lot of farting and loud farting sound need to do abdominal examination and stool examination, and if necessary, gastroscopy and enteroscopy to make clear whether there is any organic lesion of the intestinal tract. People with loud farting sound and farting a lot, if accompanied by other discomforts, need to actively consult the doctor to avoid further aggravation of the condition.
