Farting a lot without odor may be caused by dietary factors, or it may be caused by digestive system diseases. 1. Dietary factors: If you eat too much food that produces gas easily, such as green carrots, soybeans, onions, sweet potatoes, etc., you will have a lot of farts but no odor. If you eat too fast, you will produce too much gas in your stomach, which will lead to a lot of farts but no odor. Generally, there is no need for special treatment, only need to adjust the diet structure, improve eating habits can be relieved. 2. Digestive system diseases: Digestive system diseases such as peptic ulcer, irritable bowel syndrome, inflammatory bowel disease, intestinal tumors and so on will lead to intestinal flora imbalance, slowing down of gastrointestinal peristalsis, which affects the digestion and decomposition of food, and makes the food stay in the intestinal tract for a long time, which will lead to farting, but not smelly symptoms. If the fart continues to increase after improving diet, you should seek medical advice in time and cooperate with medical personnel to improve the relevant examination, clarify the cause of the disease and target treatment.
