Diagnosed with PCOS at 24, now 31, BMI 34. I have been told for years that losing weight will improve my symptoms, and separately that insulin resistance is the…

Endocrine changes accompanying substantial weight loss: sex hormone binding globulin, testosterone, oestradiol, cortisol and the reproductive axis, including PCOS-specific findings.
Hypothyroid on 125 µg levothyroxine for six years, stable TSH around 1.4 mIU/L that whole time. Since starting tirzepatide nine months ago and losing 21 kg, my TSH…
Baseline, before starting treatment: total testosterone 2.6 nmol/L, SHBG 22 nmol/L. After eight months and 16 kg of weight loss: total testosterone 1.9 nmol/L, SHBG…

Stated plainly: dulaglutide · mazdutide. Both of these get recommended confidently by different people, which suggests neither is obviously right. My constraints are…
Setup, so nobody has to ask: creatinine · cystatin C · semaglutide. I suspect the honest answer is that it depends, in which case I would like to know on what. Assume…
Numbers first: fatigue · dulaglutide · SURMOUNT-OSA. This is presented as though it settles something, and I am not convinced it does. I have two documents that…
