13. Skin Tags
Small, sac-like protrusions found on the neck or eyelids, under the breasts or armpits, or around the groin. Blood-sugar and hormonal problems might be causing them.
There’s at least one good thing about skin tags, according to Michael Stone, MD, MS, a functional practitioner in Ashland, Ore.: “If you figure out the cause and respond appropriately, you might just prolong your life.”
Stone explains that skin tags can form when high blood-sugar levels drive an increase in our epidermal growth factor, which controls how fast certain areas, or what doctors call “islands,” of skin grow. They can be a sign of insulin resistance, a condition where cells don’t respond properly to the insulin that normally helps them absorb blood sugar.
Some experts estimate that up to 75 percent of the U.S. population has insulin resistance. And it’s connected to metabolic syndrome, a group of traits linked to obesity and diabetes.
