Sensitive skin and Uticaria

What is Uticaria?

The symptoms of Uticaria are most commonly a rash that is very itchy and consists of a number of raised bumpy weals on the surface of the skin. In an acute attack it can last between several hours and a few weeks, uticaria that last longer than six or so weeks is less likely to be caused by an allergy and is called chronic uticaria.  Acute uticaria is caused by an allergy.

He most likely suspects for acute uticaria include allergies to animals such as dogs, cats and horses and common foods such as eggs and dairy particularly milk in children, peanuts, shellfish and dairy for adults. Sometimes people can be allergic to bee stings, wasp stings and even certain medicines such as antibiotics, in particular penicillin and other medications.

What are the symptoms of uticaria?

The rash that develops is very itchy and usually has lumpy, bumpy skin that develops along with a rash. Sometimes the rash can move around the limb or body and be so severely itchy it interferes with the person’s ability to sleep and their quality of life. Uticaria causes super sensitive skin and commonly red lines develop when the skin is itched called dermatographism. There is a relationship between stress and the uticaria reappearing, mental and emotional stress and when the body is challenged by a physical illness. Sometimes acute attacks occur when there is a viral illness and the body’s immune response is lowered.

What can we do?

• Try to avoid stresses we recognise can cause acute attacks such as alcohol, stress, hot weather, tight itchy clothing and harsh laundry detergents.

• Avoid foods we know or may have a reaction to, additives such as salicylate, sodium benzoate, sulphur dioxide, tartrazine and MSG or Mono Sodium Glutamate among others.

• Examination by a doctor is needed to determine the cause if mild symptoms become worse or persist for weeks.

• A doctor may prescribe some medication or run some blood tests to determine if there is an underlying allergy or an auto immune disease.

• A course of antihistamine tablets may settle the symptoms of acute uticaria but if it doesn’t respond or you have some associated health problems then see a doctor.

• A doctor may prescribe a short course of oral steroids if the symptoms are severe.
