Wounds That Do Not Heal
Wounds that take longer than normal to heal may be a sign of type 2 diabetes. In some cases, the wounds or cuts do not heal at all and require medical attention. Fluctuations in blood sugar levels prevent the bloodstream from delivering vital nutrients to the wound to heal them, which causes prolonged pain and swelling. Talk to a doctor if cuts, scrapes, or wounds do not improve on their own; this may be a sign of a blood sugar disorder, such as type 2 diabetes.
