A lot of people are walking around exhausted, foggy, moody, and struggling with their cardiovascular health blaming stress, diet, age, and everything in between, never once considering that the real culprit might be happening in the eight hours they are not even awake for. And in children, what is being labeled as ADHD and treated with medication could in many cases simply be an undiagnosed sleep disorder that nobody thought to look for. In this episode of Extend, I sit down with Dr. Meredith Br...

Fatigue, brain fog, weight gain, hair loss, low libido, high cholesterol, and a doctor who keeps telling you your labs look normal. For the millions of people walking around with an undetected or poorly managed thyroid condition, this is not just a frustrating experience but a dangerous one. Because what their doctor never told them is that the most important thyroid marker, the one that actually powers every cell in the body, is only being checked 4% of the time, which means the test they are r...
