What is urticaria?
Urticaria is hives which means rash on your body. It is reddish wheals or welt bumps that appear on your skin. Urticaria is also known as Nettle rash. This condition mainly consists of wheal spots or patches of raised red and white skin, each of which clears away in few hours to be replaced by fresh wheals. The welts may vary in size and fade repeatedly as the reaction course sets in. It sometimes occurs together with swelling of various parts of the body typically the face, hands, and feet called angioedema. Angioedema is another skin condition and name given to the deeper swelling affecting the tongue mouth throat and upper airway.
Urticaria with angioedema may occur at a different time or together in the same person. It may occur in two forms. A wheel that is skin-colored or pale skin swelling usually surrounded by erythema or redness that lasts anything between a few minutes to twenty-four hours. It usually causes itching and burning pain in the skin. Angioedema is the deeper swelling within the skin and the mucous membranes. When hives last more than 6 weeks it is considered chronic. And when hives are without any cause it is considered idiopathic. Hives can be very uncomfortable interfering with sleep and normal day to day activities. Sufferers often don’t say anything at all they are too busy scratching which may lead to worsening of the situation.
What causes the rash?
Most of the time you cannot pinpoint the cause of the rash. Whatever is the cause your immune system senses as a hostile invader and kicks into an overdrive mechanism. Tiny build vessels begin to leak protein-rich fluid and this causes a build-up of the fluid under the skin leading to red patches wheals and welts which results in excessive irritation of skin along with itching. The first line of defense is the skin.
There are two types of urticaria :
Acute urticaria: which lasts for the duration of up to less than six weeks
Chronic urticaria: which lasts for more than six weeks which episodic flare-up of wheals.
An outbreak that looks alarming the first thing in the morning can be gone by noon only to be back in full force later in the day. Because hives fluctuate so intensely and so fast it is helpful to bring along the photograph to a dermatologist for further evaluation. Hives appear when histamine and other compounds are released from the cells called the mast cells which are found in the skin. Histamine causes the fluid to leak from the local blood vessel leading to swelling of the skin. Hives are very common but not contagious.
Despite the reputation of hives being an “allergic reaction” there is an obvious connection of provoking substrate.
which means skin writing is a common cause of physical urticaria. This is an exaggerated form of what happens to someone when the skin is rubbed or scratched, a red velvet appears at the site of the scratch. In dermatographism, raised itch welt red skin with adjacent flares appears when the skin is scratched or where belts or other clothing rub against the skin.
Cholinergic hives: Another form of hives that produces hundreds of welts and itch after fifteen minutes of physical exertion. This kind of cholinergic hives is seen mostly in young people.
Theories: There are several theories among researchers that may lead to this condition of urticaria :
Autoimmune theory: In some patients with chronic spontaneous urticaria, the release of histamine from mast cells triggered by certain factors in the blood can lead to a process known as autoimmunity which is the theory behind urticaria. Although hives are associated with allergic reactions they can be triggered by :
- Medication: If you suspect any medication causing the urticaria as a side effect inform your doctor about the same
- Insect bites
- Eating shellfish, nuts, apples, and peaches
- Cold temperature: Temperatures change may cause the hives to trigger leading to the presence of wheals on the skin. It may cause dryness of skin which may lead to itching.
- Harsh soaps or detergents
- Underlying condition: Any kind of allergic reaction or underlying allergy can cause hives. In some cases, the hives may be due to thyroid disorder which is an autoimmune condition that needs to be treated.
- Pet allergies
- Hay fever
- An autoimmune disorder like diabetes type 1, lupus, rheumatoid arthritis.
- Identifying what’s triggering your rash is essential as it can lead to avoidance of Allergan.
Signs of severe allergic emergency may require care like
- Swelling of face or throat
- Difficulty in breathing
Signs and symptoms of urticaria :
- A rash which is raised swollen like hives with reddish velvety bumps
- Itching developed in the affected area of rash
- Selling of throat eyelids and lips (Angioedema)
- Heat exercise and stress may aggravate these symptoms
A confirmed diagnosis can be a feature of the skin condition as well as the symptoms. Also, a professional doctor will give you a blood test in the form of an allergy test to confirm the same.
