Dr. wants me to do ct scan of abdomen bc of stom. cramps, not able to lose weight for 6+ mos. skeptical bc i had ct of chest negative/ all tests neg. feeling extreme nauseated today. help? radiation?

You are right: About the radiation exposure unless the benefit outweighs the risk. Would hate to second guess your doctor with no specific information. Ask your doctor what he/she is hoping to confirm or rule out by the scan.

Have the CT scan: The ct scan is one of the best ways to determine the cause of abdominal pain. Radiation exposure is modest and not a clinical issue.

Abdominal Pain eval: A ct of the abdomen is part of the evaluation of abdominal pain. However it certainly is not at th ebeginning of the evaluation. A through history and physical exam. Then consideration for less expensive blood work including liver and pancease blood tests and possibly stool studies. In a 21 y/o female the commonest cause of abdominal pain is constipation, followed by acid related irritation.
