Every January, I go for my complete physical examination. Every year I'm excellent. I only take medication for glaucoma, Timolol and Lantropost eye drops. This past January 2013, when I went for my physical examination, my doctor found a slight murmur and sent me for an echo. It showed a mild mitral valve leak. It blew my mind because I do everything right. I exercise every day and also walk. I eat a healthy diet, more fish and chicken and veggies & fruit. Red meat one a month. I can't beleive that my doctor told me this. Can the beta blockers that I use Timolol cause this. I am freaking out bigtime over this. My doctor told me not to worry, but how could I not worry. This is making me very depressed. I was alway a very happy person,, now I'm, a basket case. I also have an identical twin sister. We have the exact DNAs, she also has glaucoma, but her optomologist has her only on lumina 0.01%. I forgot to mention that my total cholesterol is 187, triglyserides 64, HDL 72 and LDL 101. Dr. please answer my question ASAP. I have an appointment with my othomoligist on June 13, and I'm going to mention it to him.
