I went to my gynecologist because I am 47 and thought I may be having perimenopause issues: 30 lb weight gain, skin issues, very tired, can't sleep, moodiness, excessive sweating, etc. She said it is NOT menopause or hormone related. I asked her if it could be thyroid and she said that it was a possibility. So she ran a CBC, TSH and Free T4. My MCHC (for anemia) was just under at 32.3 (range 33.0 to 36.4), my TSH was .751 (range .45 to 5.00) and my Free T4 was .75 (range .71-1.85). I am not sure what the issue is but she thinks that things are fine. I DO NOT feel normal. I feel terrible constantly. No energy, drained. Watch food intake, eat less now than before but wear 3 clothes sizes more....I know something is off.....somewhere.
