I am 72 have not been on any medications yet. My last annual visit I was told I am slightly hypothyroid but no medication at this time. My concerns are I was 130lbs three yrs ago and went down for two yrs now to 112lbs. I feel great but I can not gain weight and my memory is shot for the last 2yrs a steady 112. I am blessed my whole life to sleep sound and wake up feeling great but during the day I keep busy in my home and do not do any exercises to strengthen my bones or muscles and my skin is hanging and wrinkly. My conversations are on speed dial so to speak and my patience are short where I deep breath to calm my self down . A few times before bed I get heart palpitations and deep breath to calm down. Any idea what is going on? I contacted my family doctor to see if I should see an endocrinologist for my hypothyroid. What do you folks think since I haven't heard back from my Dr. yet? Since I won't be speaking to you I am leaving this site.
