If you have not eaten much but have a bulging stomach, it is possible that bloating exists. If it is recent, it is correlated with the individual’s diet and mental state. It is necessary to have a reasonable diet with easily digestible food and coarse fiber vegetables with stems. This will not increase the burden on the gastrointestinal tract and will help improve the digestive function, especially the coarse fiber food, which stays in the intestine for a shorter period of time and stimulates gastrointestinal motility, especially for people with constipation. Medication can be given to improve gastrointestinal function and promote gastrointestinal peristalsis, such as stomachic and digestive tablets, Itopride tablets, to achieve moderate activity after meals. If convenient, it is recommended to go to the hospital for examination, such as abdominal plain film or ultrasound examination, to exclude other organic diseases.
