The reason doctors feel your abdomen is to see if you feel any pain in those areas and to make sure everything is normal.
The doctor will usually ask you if you feel any pain when they press on or feel your abdomen.
The doctor is also checking for any abnormalities in your organs and their sizes as well.
Your abdomen includes all your digestive organs including your stomach as well as small and large intestines, pancreas, liver, and gallbladder.
So the doctor wants to feel your abdomen to make sure all those organs are the correct size and feel okay and any abnormalities then the doctor may request X rays to see what is going on.
