Hidden pain above the belly button is not necessarily a precursor to cancer, but may be due to diseases such as overeating, indigestion or stomach ulcers. Eating too much may cause pain above the navel. Some people have no control over eating and often lack self-control over the food they like to eat, resulting in pain above the navel after a full meal. In addition, when patients have gastric ulcer, gastritis and other stomach diseases, irregular diet can also cause pain above the navel. If it is caused by gastric ulcer, the pain is more obvious about half an hour after eating. Patients should usually do some simple sports according to their physical condition and do some exercise within their ability, like walking and jogging, which can improve their resistance. In addition, it is recommended to consult the hospital internal medicine department for treatment as early as possible to avoid delaying the condition.
