Hi, I've suffered from severely chapped lips since I was a teen. Never knew there were names for it. Was diagnosed with hypothyroid a month ago. It takes 2-3 months to begin working so will have to see if it does help.
I take calcium supplements daily due to osteoporosis and tend to drink more than the recommended 8 glasses of water a day.
Have been trying more expensive lip repair remedies before knowing about hypothyroid connection. They help but don't heal. I am always tired with very low metabolism. I suspect I've had hypothyroid for years but it didn't show up on tests until recently. Glad to have found this group. Will share if the thyroid meds impact lips.
