Episode 16: The Adrenal Gland in Kids: Cortisol, Early Puberty, CAH & Adrenal Fatigue Explained

Dr. Rinku Mehra and Dr. Lindsey Waldman of the Endo Kids Podcast explain the adrenal glands’ structure (cortex and medulla), hormones (cortisol, aldosterone, adrenal androgens, adrenaline), and brain regulation via the hypothalamus, pituitary, and ACTH feedback loop. They clarify cortisol’s essential roles in blood pressure, blood sugar, inflammation, and stress response, and contrast adrenal insufficiency (fatigue, weight loss, low blood pressure, salt cravings, hyperpigmentation) and adrenal crisis (vomiting, dehydration, hypoglycemia, shock) requiring urgent hydrocortisone and IV fluids. They discuss excess cortisol/Cushing syndrome (weight gain with slowed height, round face, stretch marks, hypertension, mood changes), premature adrenarche versus central puberty, rare catecholamine tumors like pheochromocytoma, and common testing approaches. They cover congenital adrenal hyperplasia (often 21-hydroxylase deficiency), newborn screening, treatment, and stress dosing, and debunk “adrenal fatigue” while warning that unnecessary steroids can suppress adrenal function.00:00 Welcome to Endo Kids00:55 Adrenal Glands Overview02:52 Cortisol Basics04:06 Adrenal Insufficiency05:38 Adrenal Crisis Signs06:40 Too Much Cortisol08:25 Adrenarche vs Puberty10:56 Adrenal Medulla Hormones11:46 Testing and Workup12:24 Congenital Adrenal Hyperplasia14:51 Adrenal Fatigue Myth16:51 Cushing Syndrome Deep Dive20:01 Premature Adrenarche Tips21:08 Rapid Fire Questions24:38 Steroids and Adrenal Suppression26:30 Key Takeaways and Wrap Up27:06 Subscribe and ResourcesMedical Disclaimer: The information shared on The Endo Kids Podcast is for educational purposes only and does not constitute medical advice.
