1. Overeating or Eating too fast

An upset stomach after a meal can be a result of eating too fast or overeating. Dumping too much of food in your stomach may lead to indigestion. While chewing, food mixes with your saliva. The enzymes in the saliva start the digestion process by breaking down the food into starches and fats.

If you eating too faster, saliva does not mix with your food and causes indigestion. Also, the overeating does the same process. Having severe stomach pain after eating anything indicates that your stomach does not bear the dumping and it need to expel out something.

Just avoid over dumping foods at a time and take foods at regular intervals to treat the stomach pain.

2. Lactose Intolerance

Some people may feel that their stomach always hurts after eating. This may be due to the lactose intolerance. This illness is also called as lactose malabsorption.
