2. Spots on the skin
Skin changes are another symptom of high blood sugar levels. You should definitely check your blood sugar levels if you notice dark spots on your elbows, joints, or the back of your neck. Dr. Sanjiy Saini, a dermatologist in Egarwater, Maryland, explains that these changes indicate elevated blood sugar levels and other specific genetic or hormonal conditions.
He says the dark color of the blemishes is due to melanin, which is stimulated by increased insulin levels. He added that these skin changes indicate that the patient already has diabetes. However, once the patient’s blood sugar levels return to normal, these dark patches can be treated with laser therapy.
3. Hearing problems
If you have hearing problems, especially hearing loss, you should probably get your blood sugar tested. According to a study conducted by the National Institutes of Health, hearing loss can also be a symptom of diabetes. Although this condition is not usually associated with diabetes, this study demonstrates that there is indeed a direct correlation between the two.
Experts explain this because of the damage high blood sugar causes to the blood vessels and nerves of the inner ear, which leads to hearing loss. Patients with elevated blood sugar levels have a 30% higher risk of hearing problems than those with normal blood sugar levels. Therefore, monitor this parameter if you suspect you have problems with your blood sugar.
