Abnormal changes in the face may be an early indicator of blood sugar issues. Family physician Dr. Li Sihsien explains that while early-stage diabetes often shows no obvious symptoms, the face can reveal warning signs. If someone exhibits three or more of the seven key signs—such as swelling around the eyes, thinning hair, or adult acne—they should seek medical evaluation promptly, as they may have diabetes or uncontrolled blood sugar.
Adult acne, often dismissed as a cosmetic issue, may actually be linked to hormonal imbalances and insulin resistance. Dr. Li noted on the “Churibi Medicine – Song Yanren x Cofit” YouTube channel that while a diabetes diagnosis requires professional blood tests, facial changes can serve as an early alert. Taiwan currently has over two million people with diabetes, many of whom may be unaware they are at high risk.
Key Facial and Oral Signs to Watch For
- Eye Swelling: Not just typical “eye bags,” this may relate to chronic inflammation and insulin resistance.
- Thinning Hair: Beyond aging or male-pattern baldness, hair loss may indicate thyroid dysfunction, which can be associated with insulin resistance. In such cases, tests for both hormones and insulin-related markers are recommended.
- Acne or Breakouts: Common in adults with hormonal imbalances and insulin resistance.
- Darkened Skin Patches (Acanthosis Nigricans): Darkened areas on the neck, armpits, joints, and groin may result from high insulin levels, not poor hygiene.
- Dry Lips or Mouth: Frequent urination from diabetes can lead to dehydration, causing dry or chapped lips and a dry mouth.
- Teeth Marks on Tongue: Known as “scalloped tongue,” this occurs when swelling in the tongue presses against the teeth.
- Facial Spots or Discoloration: Long-term high blood sugar can cause glycation of the skin, leading to spots; improvements in blood sugar often reduce these blemishes.
Dr. Li emphasizes that if three or more of these signs are present, individuals should seek professional medical advice and consider blood tests to check blood sugar levels. Early detection allows for timely intervention and better management of diabetes.
