A man’s stomach is getting bigger and bigger at 50 years old, which is mainly considered to be related to indigestion, obesity, liver and kidney diseases, and so on. 1. Indigestion: When indigestion occurs, the ingested food is stored in the gastrointestinal tract, which will result in bloating and other conditions, and people will feel that their stomachs are getting bigger. 2. Obesity: people in their 50s lack exercise in their daily life and gain weight. Obese people gather a lot of fat in their abdomen, and their stomachs may also become very big. 3. Liver and kidney disease factors: Cirrhosis, liver disease syndrome, nephritis, nephrotic syndrome, abdominal distension, abdominal pain, abdominal enlargement and other symptoms. As each person’s specific situation is different, it is recommended to go to the hospital for examination, to clarify the cause of the disease under the guidance of a professional physician, and to carry out treatment.
