Diabetes is one of the lifestyle disorders, a chronic condition characterised by high blood sugar (glucose) levels. It is an outcome of either insufficient insulin production by the pancreas or ineffective use of insulin by the body. Insulin is a blood glucose regulatory hormone. This condition can impact an individual’s physical health which includes skin health. The most common is skin rash caused by diabetes.

Some diabetics experience skin problems when they have uncontrolled blood sugar levels. There are few skin conditions known to be linked with diabetes.

Can diabetes cause skin rash?

Skin rash like acanthosis nigricans is one of the skin concerns that a diabetic is more likely to develop because of high sugar levels in the blood. It can even be a sign of prediabetes, for people who have not been diagnosed with diabetes.

Hyperglycaemia (high blood sugar) can cause dehydration, leaving the skin dry and more susceptible to skin issues like skin rash. It even impacts blood circulation and the natural healing of the injured or infected skin.

For all those who are on diabetes medication, an appearance of skin rash may indicate that the current treatment is not able to lower blood sugar levels effectively. Therefore, there is a need to consult the treating doctor for review who may bring in changes in the medication and treatment plan for diabetes.

Skin rashes that develop in people with type 1 or type 2 diabetes are called diabetes rashes. It is a temporary condition that may resolve with the management of blood sugar levels.
