@mydogsbestfriend welcome to Mayo Clinic Connect. I see from your post that (though you are not diabetic) you have some meds that affect a variety of systems and perhaps causing digestive problems. The levothyroxine is for thyroid, part of the endocrine system. Amlodipine is for blood pressure or cardiovascular system. Areds & Lutein are for your eyes. Have you discussed your digestive concerns with your primary (or the prescribing physician)? Maybe he can consider other alternative medications.
