Fatty liver itself will not cause stomach bloating, most of the patients with fatty liver do not have any clinical symptoms, and most of them are found to have fatty liver only when they have physical examination, especially those who are obese or overweight. A small number of patients with fatty liver may show bloating, loss of appetite, fatigue, anorexia and so on if their liver function is obviously abnormal, but the degree is relatively mild and often overlooked by patients. Most of the flatulence is caused by stomach diseases, such as chronic gastritis, gastroesophageal reflux disease, peptic ulcer, or there is no organic disease of the upper digestive system, but due to functional gastrointestinal diseases, such as functional dyspepsia may appear symptoms of flatulence. Patients can go to the hospital, cooperate with the doctor to give a complete relevant examination, if necessary, give the use of drug treatment.
