Dr. Tabatha Barber explains how chronic gut problems can slow your thyroid by raising reverse T3 and lowering active T3, which tanks metabolism. The result: constipation, hair loss, brain fog, and stubborn fat that won't budge.
Her thyroid was stuck in this downregulated mode of trying to turn down her metabolism because she also had chronic gut issues going on. And the thyroid will respond to chronic gut issues every time. It will make more reverse T3 instead of active T3. That is like putting your foot on the brake, slowing everything down. It slows your bowels down so you're constipated. It slows down your hair growth or even causes hair loss. It prevents you from losing weight or burning fat, and it gives you a little bit of brain fog. All the struggles.
