The Blood Tests Your Doctor Should Be Ordering (But Isn't) | Body Clock Podcast

Episode 003 continues the PCOS/PMOS conversation and gets concrete about diagnosis. Dr. Herman Weiss, an OB-GYN with more than 25 years in practice, walks Daniel Kaufman through the markers and blood work he orders and the order he orders them in — starting with cycle pattern and history, moving through his basic panel, the androgen picture, SHBG and AMH, and finishing with the insulin-resistance workup. His recurring argument is that a lab result inside the reference range is not the same as a patient being well, and he explains two specific ways that happens. Around that core, the episode covers why habit change is so hard, Daniel's candid account of his own GLP-1 experience and rebound, why Dr. Weiss calls BMI worthless, how cortisol's morning spike shapes his thinking on when to eat, and what his daughter's gestational-diabetes pregnancy taught them both about personal blood sugar responses. What Listeners Will Learn: What Dr. Weiss considers a normal menstrual cycle — and why a period every two to three months is not a benign variation The presenting history he treats as hallmark: irregular or absent bleeding, acne, chin, chest and back hair, patchy discoloration Why he orders a sonogram to separate a hormonal cause from a structural one How a low SHBG lets a normal total testosterone hide a high free testosterone Why living at low-normal and spiking to high-normal can leave every lab inside the goalposts while symptoms are obvious Why he now looks at AMH, and the claim that it has been arguably more sensitive and more reliable than ultrasound in some studies The insulin-resistance workup: fasting insulin and glucose, HOMA-IR, HbA1c, and the two-hour glucose challenge that catches emerging metabolic syndrome How to advocate for the tests you want, and why to repeat them if symptoms persist despite normal results Why he considers BMI worthless, and why it still gates GLP-1 insurance approval Thyroid dysfunction and congenital adrenal hyperplasia as mimics of PCOS Why cortisol's morning spike makes him question intermittent fasting Why gestational diabetes is screened at 24 to 28 weeks, and why a big baby is a risk rather than a reassurance The ten-minute walk after an insulin spike, and eating fiber before the rice Chapters: 0:00 Picking Up Where We Left Off 0:49 Why Changing Habits Is So Hard 2:49 Daniel's Weight-Loss & GLP-1 Story 5:16 GLP-1s: Too Good to Be True? 9:03 The Couple Who Did It Without the Shots 10:37 Muscle, Male Obesity & Infertility 12:31 What a Normal Cycle Looks Like 14:02 Sonogram, History & the Basic Blood Panel 16:17 SHBG: When "Normal" Testosterone Misleads 17:39 AMH: An Emerging Marker 18:27 The Insulin Resistance Workup 19:35 Ask for the Tests (Don't Take No for an Answer) 20:39 Are "Normal" Ranges Wrong?
