Pruritus (itchy skin)

What is pruritus?

Pruritus is another term for itching. Pruritus can affect anyone, but mainly affects the elderly. It can be caused or associated with a wide variety of conditions, not just those affecting the skin. Pruritus can also be a reaction to certain substances or medication. 

What are the causes of pruritis?

It’s normal every once in a while to feel itching on the skin, and many things can cause an itch, including the material your clothes are made from, an insect bite, or dry skin. However, itching can be a symptom of an underlying condition, so it’s important to note if the pruritus continues, the areas it affects (e.g whethr it's localised or all over the body) or if it is a one-off sensation.

Itching can be caused by many different conditions or states. Some women feel itching during pregnancy, due to medical conditions which can occur at the time (e.g gestational pemphigoid). Menopause can also be a cause of itching, as can certain medication. Other varied causes include (but are not limited to):

Infections such as: 

Underlying conditions: 

Skin conditions: 

  • Dandruff
  • Dry skin
  • Skin irritation (e.g reaction to shaving)
  • Scabs and scars healing over
  • Psoriasis
  • Eczema
  • Sunburn
  • Athlete’s foot

Environmental factors such as:

  • Allergic reaction
  • Hives
  • Skin problems caused by the sun
  • Foreign objects

What are the symptoms?

Itchy skin can be associated with redness, marks made by scratching and bumps, spots or blisters. Furthermore, it can be related to:

  • Dry, cracked skin
  • Patches of skin that are scaly or feel leathery

Can itchy skin be prevented?

You can’t really prevent feeling itchy, unless it is caused by something you know to be an irritation to your skin that you can avoid. You can follow some tips to avoid further damage to the affected area when your skin feels itchy:

  • Not scratching
  • Wearing comfortable, fresh, clean clothes
  • Use mild soap
  • Use moisturiser
  • Apply cold compresses to the affected area
  • Use a humidifier, and avoid excessive heat or a dry environment
  • Rest or do activities that help distract you

How is pruritis treated?

If the itching is intense, does not disappear or is difficult to explain, it is important to visit your doctor. If the cause is an underlying condition or can be identified, it will be treated. In cases of skin irritation or external irritation, your doctor may prescribe a cream to treat the affected area and, in some cases, may also recommend medication, such as antihistamines.

Which specialist treats itchy skin?

If you require a referral for pruritus, you will see a dermatologist, a specialist in skin diseases.
