I am a 57 yo male who is hiv + diagnosed in Aug of 2006,I am currently on Kaletra and 2 other Hiv meds. I also have family history of colon cancer,so I get a colonoscopy every 5 years,the last being 3 years ago,and was clean,I also had a endoscopy at the same time and was normal,I have noticed that since I have been on these meds,My stool varys in texture and consistantsy,I also have occasional right shoulder pain. I was wondering how often you should have a coloscopy. My blood work is normal,except elevated triglycerides,and I do know that the Kaletra can cause this,but can the triglerides couse increase in stools and the texture. Thanks I also had a ultrasound 2 years ago.
