Bad breath and frequent farting are not necessarily caused by infection with Helicobacter pylori. It can also be caused by gastrointestinal flora disorders and indigestion. 1. Helicobacter pylori: Helicobacter pylori infection can cause indigestion symptoms, as well as gastritis, peptic ulcer and other diseases, which will significantly weaken the body’s ability to digest and absorb, thus affecting the initial digestion of food. Undigested food into the intestines will increase the digestive burden of the intestines, resulting in excessive gas accumulation in the intestines and the appearance of many farts. 2. Gastrointestinal flora disorder: Due to the imbalance of gastrointestinal flora, food stays in the digestive tract for too long, resulting in bad breath and frequent farts. 3. Indigestion: Insufficient gastrointestinal power, slowing down of peristalsis leads to lack of trypsin, and food is stored in the gastrointestinal tract for too long, resulting in bad breath and a lot of farts. If the patient’s symptoms of bad breath and farts continue to be unrelieved, he should go to the hospital in time for relevant examinations, clear diagnosis and timely treatment, so as not to delay the condition.
