						Although  skin benefits from maintaining good nutrition, circulation, and external care,  there are situations where your skin may have a disorder that good skin care  can’t prevent.
						
  
						Many skin  disorders are caused by underlying medical disorders and diseases, including:
                        
                        
                          - diabetes
 
                          - liver       disease
 
                          - heart       disease
 
                          - lupus
 
                          - blood       vessel diseases, such as arteriosclerosis
 
                          - stress
 
                          - and       obesity
 
                         
                        Interestingly, skin disorders are common among the elderly,  so it is often difficult to tell normal aging changes from those related to a  skin disorder. More than 90% of the elderly have some type of skin disorder.
						
  
                        As the skin  is the largest organ in the body, any disease that affects the body is very  likely to have symptoms showing on the skin. Some dermatologic diseases are  caused by medical diseases, and when the diseases are not treated the skin  component of the disease can get worse. A good example of this is diabetes. If  the diabetes is well controlled there are usually relatively few problems with  the skin. However, if the diabetes is uncontrolled, any of these dermatologic  problems can result:
                        
                        
                          - Diabetic       dermopathy – brown spots/scars on shins, sometimes preceded by red or       blistering spots
 
                          - Gangrene       – tissue death as a result of the blockage of blood vessels in the feet
 
                          - Diabetic       neuropathy – nerve damage in the feet, causing skin sores, ulcers, foot       drop and lack of sensation or feeling in the feet
 
                          - Skin       Infections – styes, boils, cellulitis, necrotizing fasciitis, fungal       infections
 
                          - Necrobiosis       Lipoidica – skin lesions on shin with reddish brown borders and a       yellowish centre
 
                          - Acanthosis       nigricans – dark velvety thickening of the skin folds in armpits, upper       back, neck and groin
 
                          - Xanthomas       and Xanthelasma – yellow firm nodules around bony elbows, knees, and       heels, as a result of fat deposits in the skin from high cholesterol
 
                         
                        
                        
                        There are more defined and distinct diseases involving the  skin than there are for any other organ in the body. At present there are over  1200. We at the Skin Care Centre treat them all. Here are 15 of the most common  skin disorders (please click on the links below):
