Long-Term Complications of Diabetes
Diabetes can cause health problems over time. These are called complications. They are more likely to occur if your blood sugar is often too high. Over time, high blood sugar can damage blood vessels. It is important to keep your blood sugar in your target range. This can help prevent or delay complications.

Possible Complications
Complications of diabetes include:
Eye problems, including damage to the blood vessels in the eyes (retinopathy), pressure in the eye (glaucoma), and clouding of the eye’s lens (a cataract)
Tooth and gum problems (periodontal disease), causing loss of teeth and bone
Blood vessel (vascular) disease leading to circulation problems, heart attack, or stroke
Problems with sexual function
Kidney disease (nephropathy)
Nerve problems (neuropathy), causing pain or loss of feeling in your feet and other parts of your body
High blood pressure (hypertension), putting strain on your heart and blood vessels
Serious infections, possibly leading to loss of toes, feet, or limbs
How to Avoid Complications
