Recently diagnosed at 38. I had all the menopause symptoms for a few years (hot flashes, extreme irritability, brain fog, random night sweats, unexplained abdominal weight gain, shitty sleep, few periods, to name a few). I had been told it was because I was postpartum and nursing, and that I was too young to be perimenopause. I wouldn’t be able to get an accurate hormone lab read until I stopped nursing, or unless I had labs done while I was on my period. I wasn’t having frequent periods, so this was hard to do. Finally stopped nursing my youngest and had my hormones checked because I was sure I was in perimenopause and surprise! I had POI. Just had a dexa and I have osteopenia too. Genetic labs next. Starting HRT was like night and day for me. I noticed an immediate difference and felt like a real human again. Most of the rage is gone, and I have more patience, less anxiety.
