What is Diabetes Mellitus?

Jump to Heading

Diabetes mellitus is a common disease affecting about 8% of the adult population in Singapore. Diabetics have high blood sugar levels which if not well-controlled can lead to long-term complications affecting various organs in the body such as the eye, kidney, nervous system and blood vessels. Skin problems are common in diabetics. Some skin diseases are characteristically associated with diabetes mellitus.

Diabetes Mellitus Complications

Diabetic dermopathy

This is the commonest skin disease seen in diabetics. Skin signs are commonly found over the shins and appear as brown scars. The brown spots may be preceded by red or blistering spots. The cause is due to abnormal changes in small blood vessels in the skin. There is no specific treatment for this skin disorder. The condition tends to heal by itself into depressed scars.

Gangrene

Occlusion of large vessels in the feet due to diabetes can cause pain on prolonged walking as a result of poor blood circulation. Severe occlusion can lead to gangrenous changes in the toes as a result of tissue death. Surgery will be needed to remove the dead tissues and in severe cases, amputation of the foot or leg.

Diabetic neuropathy

Diabetes can damage the nerves resulting from the occlusion of blood vessels to the nerves. This can cause a burning and tingling sensation and numbness in the feet. Patients also have reduced or loss of pain sensation and may develop skin sores and ulcers on the feet due to trauma if good foot care is not instituted.

Diabetic neuropathy

Skin Infections

Diabetics are more prone to skin infections. Examples are styes, boils and fungal infections. Some infections can be serious and require immediate medical attention eg. carbuncles, which are deep bacterial infections of the hair follicle (abscess) and cellulitis which is a deep skin infection. Cellulitis often presents as a red, hot and tender swelling of the leg. Necrotising fasciitis is a serious and life-threatening skin infection which may extend deep down to the muscles and requires immediate treatment and surgery. It presents as painful, inflamed haemorrhagic swelling or blistering of the skin.

Necrobiosis Lipoidica

This is a rare complication of diabetes, again due to small blood vessel disease of the skin. Skin lesions usually appear on the shin. The affected skin has a reddish-brown border with a yellowish centre. Sometimes, the onset of this skin disease may precede the diagnosis of diabetes and so patients with this skin disorder need to be screened for diabetes.

Acanthosis nigricans

This is a skin manifestation of diabetes mellitus. It is also a skin sign of other internal diseases including some hereditary diseases and internal cancer. It is commonly seen in those who are obese. Skin changes are characterised by dark, brownish-black velvety thickening of the skin folds such as the armpits, upper back, neck and groins.

Xanthomas and Xanthelasma

Diabetics often suffer from high lipid (cholesterol and triglycerides) levels in the blood. This causes fats to be deposited in the skin and presents as xanthomas or xanthelasma.
Xanthomas are symptomless yellow firm nodules usually found over bony elbows, knees and heels. Sometimes, the appearance may be as pin-head-sized yellow lumps, appearing in crops over the buttocks (eruptive xanthomas). Xanthelasma is a sign of high cholesterol levels in the blood and presents as yellow patches on the eyelids. Treatment is aimed at normalising the lipid levels by dietary restriction of saturated fats and if necessary, medical treatment with lipid-lowering drugs.

Granuloma annulare

This is a skin disease seen usually in children and young adults. It is occasionally associated with diabetes. Skin signs are characterized by red spots in the initial stages which expand outwards in a ring-like fashion. The hands, especially the fingers, and elbows are commonly affected. When granuloma annulare is widespread it may be associated with underlying diabetes mellitus. The skin lesions may precede the symptoms and signs of diabetes mellitus. Patients with widespread granuloma annulare need to be screened for diabetes mellitus.

What should you do in case you have any of these diseases?

When there are serious complications such as bacterial skin infections, or gangrene, seek immediate medical attention. Consult your doctor early. You may need to be hospitalized. If left untreated, these complications may be life-threatening. Infected ulcers need to be treated with antibiotics.

How to prevent these complications

If your diabetes mellitus is well controlled, many of these skin problems can be averted. This requires compliance with a diabetic diet, medication and regular check-ups with your doctor. Proper skin and foot care is important:

  1. Do not walk bare-footed. This is to avoid skin injuries.
  2. Check your feet every day for cuts and sores. Pay special attention to the spaces in between the toes to look for inflammation and infection.
  3. Wear proper fitting shoes that are not too tight or loose to prevent skin trauma.
  4. Cut toenails carefully.

If skin sores or ulcers develop, see a doctor immediately. Some skin signs are also an indication that there may be possible complications affecting other organs in the body such as the eye and kidney.
