Thyroid Issues with Dr. Sapna Naik

February 20, 2026·39 min·3 clips

Dr. Sapna Nayak explains how the thyroid gland affects metabolism, weight, and energy levels in adults.

The clock is already moving. The host wraps the week, notes a foggy or cloudy morning, and brings up a warrant served near Nancy Guthrie's home. The mood drops quickly. He hopes the people detained can share where she is and how she is, then the show cuts back to weather before settling into thyroid talk. The guest explains that the thyroid makes hormones tied to metabolism, heart rate, body temperature, weight, and energy. Small gland, big job. The host keeps the terms plain, treating hyperthyroidism and hypothyroidism as the up and down versions listeners can picture. Low thyroid is the common one. The guest says hypothyroidism affects far more adults than hyperthyroidism, roughly 5 to 15 percent versus 0.5 to 2 percent. Worse is not simple, though. Either condition can be rough, because each sits at a different end of the metabolism spectrum. Low thyroid slows the body down. Tiredness, weight gain, feeling cold, and constipation are the signs she gives for hypothyroid patients. High thyroid pushes too hard. Anxiety, tremors, unintended weight loss, palpitations, and trouble sleeping are the warning lights for hyperthyroid patients. The host makes it personal with a joke about unexpected weight loss never really visiting him, which keeps the explainer loose. The health advice stays basic: for thyroid health, the guest points back to maintaining a healthy lifestyle. Then the show wanders out the side door. In the final minute, the host jumps to a lawsuit over boneless wings, calls them basically chicken nuggets, and closes on baby-shower food.
