8. Skin Changes

Diabetes can manifest in unexpected ways, including changes in the skin. Dark patches on the skin, particularly around the neck and armpits, known as acanthosis nigricans, may indicate insulin resistance, an early stage of diabetes. Skin tags, dry skin, and itching can also be symptoms of high blood sugar levels. If you notice persistent skin changes, it’s worth getting checked for diabetes.

9. Frequent Infections

High blood sugar levels create an environment where infections can thrive. People with diabetes are more prone to frequent infections, particularly urinary tract infections (UTIs), yeast infections, and gum infections. Elevated blood glucose levels weaken the immune system, making it harder for the body to fight off bacteria and fungi. Recurrent infections may be one of the early warning signs that should not be ignored.
