I have been on Diovan 80 mg for 3 years and have experience a lot of symptoms listed above. 8 weeks ago I got very sick and had constant diarrhea (my stool looked like it had oil floating on the water) and lost 40 lbs. After numerous blood work, ultra sounds, ct scans, colonoscopy and many stool samples I found out thay my pancrease was not working properly. The doctor told me that diovan had caused the problem with my pancrease. I now have to take a medication not to help me digest food and they have changed my bp pills. I am hoping this will work because I have missed a lot of work in the last 8 weeks and they tell me where I got so weak it will take me months to recover from this. Anyone having stomach problems please consult your doctor to see if you are having troubles with your pancrease.
