You may want to consider further tests for malabsorption, which can cause the symptoms. Tests to evaluate this includes the
colonoscopy (which you have already had 3 times), as well as stool tests for fecal fat. A blood test for celiac disease can also be considered.
Chronic pancreatitis can also cause similar symptoms. A blood test for amylase and lipase as well as a CT scan to evaluate the pancreas can be considered. Treatment with pancrease tablets can be considered if this disease is suspected.
If all the tests are negative, there are some cases of irritable bowel disease that can present with similar symptoms. If this is suspected by your physician, treatment with increasing fiber intake as well as antispasmodic agents can be discussed.
Followup with your personal physician is essential.
