Common causes of upper stomach discomfort include angina, gall bladder problems, pancreatitis, peptic ulcer and appendicitis, according to Mayo Clinic. Though the appendix is found in the first part of the large intestine, a pregnant woman may feel the pain in the upper abdomen because the appendix is higher up.

Though the pain of angina is associated with chest pain, it can also feel like indigestion or gas, claims the National Heart Lung and Blood Institute. Women who have episodes of angina are also more likely to feel the discomfort in their abdomen.

Inflammation of the pancreas, or pancreatitis, causes pain in the upper abdomen that can be severe, claims WebMD. The pain also radiates to the back and can be worsened by eating fatty foods. This is true of both acute and chronic pancreatitis.

The symptoms of a peptic ulcer are a burning pain in the upper stomach, says WebMD. The pain comes between meals or at night. The person may also experience heartburn, bloating, nausea or vomiting.

Gallbladder problems tend to cause pain on the abdomen's upper right side, claims the University of Maryland Medical Center. The pain comes after meals, and like pancreatitis, it is exacerbated by fatty foods. Common causes of gall bladder problems are an inflammation of the organ called cholecystitis, and gallstones.
