I'm a 32 year old male. I've lost 15 lbs in 2 months. My only other symptom is increased burping and gas that occurs throughout the day even when I haven't eaten. I haven't changed my diet or exercise patterns. I continue to consume on average 2700 calories per day. I currently weigh 168 lbs but that is quickly dropping.
My doctors have performed an MRI on my brain and neck, an upper GI of my stomach, an endoscopy where they took a biopsy of my stomach, a CT scan of my abdomen, and a host of blood work and urine tests. The doctors have considered and ruled out (to name a few) hyperthyroid, HIV, hormone imbalance, addison's disease, whipple's disease, and diabetes. A complete blood count was also performed that showed normal levels.
Based on the above tests my doctors say they can find no evidence of cancer. I am told that brain, pancreatic, gall bladder, liver, intestinal, stomach, colon, leukemia, or lymphoma cancers would have shown up on one of the above tests.
The biopsy from the endoscopy showed no evidence of celiac disorder (wheat intolerence) or any kind of parasite, although my gastrointernologist says that these conditions are sometimes difficult to diagnose. My gastro doctor has not performed a colonoscopy but says that based on my CT scan and other symptoms he doesn't see one as necessary at this time. A stool sample was also taken and came back normal.
Has anyone out there had a similiar experience? What was the diagnosis? Can anyone recommend a diagnostic test that I have not yet tried?
