The causes of regurgitation may include functional dyspepsia, irritable bowel syndrome, chronic gastritis and so on. 1. Functional dyspepsia: When functional dyspepsia occurs, it will weaken the ability of gastric emptying, which will easily cause the stomach wall to be stimulated by food, resulting in stomach cramps and regurgitation symptoms. At the same time, when the food is not completely decomposed, a large amount of gas will be produced, resulting in intestinal flatulence and increased farting. 2. Irritable Bowel Syndrome (IBS): When emotions are in a state of instability for a long period of time, it can lead to disorders of the vegetative nerve function, resulting in the occurrence of Irritable Bowel Syndrome (IBS). As a result, symptoms such as regurgitation, flatulence and farting occur. 3. Chronic gastritis: when suffering from chronic gastritis, the gastric mucosa is damaged, thus affecting the digestive function, and regurgitation, bloating, farting and other symptoms can occur. When regurgitation and farting occur, it is recommended that the diet should be light and easy to digest, avoid spicy and stimulating foods, eat regularly, and avoid overeating. If the symptoms are serious, it is recommended to consult a doctor in time to clarify the cause of the disease and then take medication under the doctor’s guidance.
