An itch is often caused by a condition affecting the skin, but it can occasionally be a sign of a more serious underlying problem.

In some cases, it may not be possible to identify a specific cause.

Skin conditions

Skin conditions that can cause itching include:

  • dry skin
  • eczema – where the skin is dry, red, flaky and itchy
  • contact dermatitis – inflammation of the skin that occurs when you come into contact with an irritant or allergen
  • urticaria – also known as hives, welts or nettle rash; it is triggered by an allergen and causes a raised, red, itchy rash to develop
  • lichen planus – an itchy rash of unknown cause
  • psoriasis – a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales
  • dandruff – a common skin condition that causes dry white or grey flakes of dead skin to appear in the scalp or hair
  • folliculitis – a skin condition caused by inflamed hair follicles
  • prurigo – small blisters that are very itchy  

Allergies and skin reactions

Itching is sometimes caused by an allergen, irritant or another environmental factor, including:

  • cosmetic ingredients – such as preservatives, fragrances, hair dye and nail varnish hardeners
  • certain metals – such as nickel or cobalt in jewellery
  • rubber – including latex
  • textiles – particularly the dyes and resins they contain
  • some plants – such as chrysanthemums, sunflowers, daffodils, tulips and primula
  • an allergy to certain foods or types of medication – for example, aspirin and a group of medicines called opioids
  • prickly heat – an itchy rash that appears in hot, humid weather conditions
  • sunburn – skin damage caused by exposure to ultraviolet (UV) rays

Parasites and insects

Itching can be caused by the following pests:

Infections

Itching may be a symptom of an infection, such as:

  • chickenpox or another viral infection
  • athlete's foot – a fungal infection that causes itching in between the toes
  • ringworm – a fungal infection that causes a ring-like red rash to develop on the skin, and can also cause an itchy scalp
  • vaginal thrush or thrush in men – yeast infections that can cause itching in and around the genitals

Occasionally, itching can be linked to a psychological condition such as depression or anxiety.

Pregnancy and the menopause

In women, itching can sometimes be caused by hormonal changes during pregnancy and after the menopause.

Pregnancy

Itching often affects pregnant women and usually disappears after the birth. A number of skin conditions can develop during pregnancy and cause itchy skin.

They include:

  • pruritic urticarial papules and plaques of pregnancy (PUPPP) – a common skin condition that causes itchy red, raised bumps that appear on the thighs and tummy (abdomen)
  • prurigo gestationis – a skin rash that appears as red, itchy dots and mainly affects the arms, legs and torso
  • obstetric cholestasis – a rare disorder that affects the liver during pregnancy and causes itching without a rash

Seek advice from your midwife or GP if you have itching or any unusual skin rashes during your pregnancy.

Menopause

Itching is also a common symptom after the menopause, which is where a woman's periods stop as a result of natural hormonal changes as she gets older.

Changes in the levels of hormones, such as oestrogen, that occur during the menopause are thought to be responsible for the itching.
