GLP-1 Side Effects No One Talks About. Hair Loss, Skin Changes, and What To Do

If you are using a GLP-1 medication and noticing hair shedding, brittle nails, or dull, dry skin, your body is signaling a nutrient gap. In this episode, Dr. Mary Alice Mina breaks down what is really happening beneath the surface and why these changes often appear before lab results do. She explains how appetite suppression can lead to low protein, vitamin deficiencies, and dehydration, all of which directly impact your skin, hair, and nails.

You will learn the key deficiencies to watch for, including B12, iron, folate, and vitamin D, and the exact signs your body shows when levels drop. Dr. Mina also explains why protein intake, fiber, and hydration are critical while on GLP-1 medications, especially for preventing hair loss, muscle loss, and skin laxity.

This episode gives you a clear, practical framework to protect your results, support your body, and avoid the most common mistakes people make while using GLP-1s.
