Your stomach is an organ where digestion of protein begins.
The stomach has three tasks.
It stores swallowed food.
It mixes the food with stomach acids.
Then it sends the mixture on to the small intestine.
Every now and then we experience a tingling stomach pain and low bowel movement that may be caused by poor digestion.
