Upset stomach may mean dyspepsia which is also referred to as indigestion. This leads to stomach pain, discomfort and tenderness of the upper abdomen. It’s only a symptom and not an illness. This is a group of symptoms that include nausea, vomiting, burping and bloating. In many cases, an upset stomach may be caused by eating or drinking food. It will also be brought on by infections or some medicines.
Indigestion is usually brought about by spicy foods, fatty foods and hiatal hernia. It is usually managed by dietary changes.
Most folks with indigestion have pain in the belly or chest. The pain happens quickly after consuming food or drink. There may even be a sensation of fullness even if that person has not eaten food.
