After a number of years of suffering from symptoms of hypothyroidism (25 lb weight gain during last 3 yrs despite diet of less than 1500 calories, depression, fatigue, thinning hair, brittle nails, and recently discovered I have high cholesterol, fasting
glucose of 99, vitamin D level (total) of 21, and shoulder impringement/rotator cuff tear) my G.P. ordered a thyroid test for me and my TSH was 3.12 with 1.0 T4 free (I was told that is normal).
