Farting can be caused by improper diet, constipation and gastrointestinal diseases. 1. Improper diet: When you have a cold abdomen or take too much gas-producing food such as sweet potatoes, onions, potatoes, etc., it may cause gas to gather in the intestines and cause farting all the time. 2. Constipation: When constipation occurs, the components in the stool remain in the intestines for a longer period of time, which may ferment and lead to an increase in the production of gas, resulting in the symptom of farting all the time. 3. Digestive diseases: when there is enteritis, gastritis and other digestive diseases, the digestive function of the intestines and stomach decreases and peristalsis slows down, which may also lead to an increase in the production of gas, resulting in the symptom of farting all the time. There may be other reasons for farting, so it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
