4. Sudden improvement in vision
If you’ve worn glasses your entire life and suddenly no longer need them, diabetes may be the cause. Dr. Howard Baum of Vanderbilt University explains that diabetes can cause both deterioration and improvement in vision. Altered blood sugar levels can also lead to abnormal blood flow in your eyes, causing a sudden deterioration or improvement in your vision.
Dr. Howard Baum stated, “ I have had patients tell me that their vision improved when their blood sugar was raised, and then after starting diabetes treatment, they needed their glasses again .” Diabetes affects vision by stimulating fluid levels in the body to move more, which can also shift toward the eyes, causing sudden visual changes.
5. Intense and constant itching sensation
If you experience itching so severe that you can’t stop scratching, you should consult your doctor immediately, as this may also be a hidden symptom of diabetes. Diabetes makes the skin irritated and dry, thus reducing blood flow. One of the most immediate and visible consequences of these biological processes in our body is a constant and annoying itching sensation in various areas of the body. Don’t ignore this symptom if it recurs frequently and severely.
