I am a 56 year old woman who has suffered with all the symptoms of low thyroid. 1 year ago my ts h level was 1.6 now a year later it is 3.6. My doctor started me on 25 mcg of levothyroxine a week ago. I don't feel as tired. My other symptoms are overweight, acid reflux which is now a little better, water retention in my legs, depression, anxiety, moody, cold and hot flashes, outer eyebrows thin, droopy eyelids, I could go on. My question is how long before other symptoms start to get better. I also take prozac, b12 shots, vitamin d. I was taking zandu c but now have stopped because of recall. When I was younger my periods were erratic and heavy. I also had 2 miscarriages. Is this all thyroid related?
