I am 64, widowed for years and not sexually active. Last August I was diagnosed with hypothyroidism and after 3 adjustments in meds I am taking levothyroxine 50 .mcg a day and seem to be doing fine. My normal weight was just under 124 and now I am up to 130 with no changes in my diet. I seemed to have leveled off and not gaining by can't lose it either...is this caused by the medication? Another concern is that in the last 3 months or so I have developed a thick yellowish green vaginal discharge. I had a hysterectomy at age 29 and not on HRT, have had no antibiotics and there is no discomfort other than the mess it causes. Can the levothyroxine cause this? Any help would be appreciated.
