THEurticaria is an annoying pathology concerning the skin. It manifests itself with "wheals", of the reddish spots of a more or less extended diameter and a lot itchy. But what is it that triggers hives? And what are the symptoms?

The swollen patches appear mainly in summer and are quite widespread and frequent among children. There is extensive literature linking a drug or food allergy to hives, but this is not always the case. Furthermore, urticaria does not need specific treatment, but most of the time the rash resolves spontaneously and within a few days.


What is urticaria, types and how to recognize it

It is a real skin disease and shows itself with a evident rash characterized by pink or red wheals at the epidermal level a lot itchy. These are lesions that can remain confined to a certain area or spread over the whole body and that typically develop in only superficial level. It may happen, however, that the spots are associated with edematous reactions of the deeper layers of the skin and subcutis and, in this case, we would speak more of "angioedema".

Generally a distinction is made between:

  • acute urticaria, for which the episodes last less than six weeks and the cause is to be found in a type infection viral o bacterial also contract a couple of weeks before the appearance of the wheals. In short, the rash occurs quickly, becomes more severe after 8-12 hours and then it resolves spontaneously within one day at most two
  • chronic urticaria, when the rash persists for a longer time and is rarely due to an allergic cause. It can also happen that allergy tests show some antibodies produced by the same organism against its components: in these cases it is a pathology of autoimmune type which would highlight the presence of other diseases of autoimmune origin, such as celiac disease.

Many cases of urticaria don't need specific treatment since the rash often resolves spontaneously within a few days. Alternatively, an antihistamine can help relieve symptoms, while more severe cases may require a short course of oral corticosteroids.

In summary, hives:

  • is a skin pathology manifesting as raised, swollen pink-red patches that cause itching
  • the patches appear especially during the spring and summer, when several factors contribute to causing it (increased exposure to sunlight, heat)
  • it does not need specific treatments, except in more complicated cases

Types of urticaria

It must also be specified that, in addition to the duration of the reaction, other forms of urticaria can be distinguished. The most common are:

  • dermographism: dermographic urticaria causes a lot of itching, but scratching causes the further appearance of wheals. Dermographism begins suddenly and is one form of chronic urticaria, due to the fact that even just touching, scratching and rubbing the skin (think of tight clothing, watches or glasses or one rubbing with a towel) can cause swelling and inflammation of the skin
  • cholinergic urticaria: it is due to excessive sweating, the application of occlusive dressings, hot baths, fever or even a moment of anxiety or concentration
  • urticaria-angioedema from cold, caused by the reaction of the skin to a reduced ambient temperature
  • contact urticaria, is none other than the "response" to the contact of a certain substance with the skin and can be of allergic or non-allergic origin, such as the stinging reaction to some plants or animals or drugs
  • vasculitic urticaria, associated with inflammation of the blood vessels

Causes hives

Urticaria is the response of our immune system to a certain stimulus, with the release of histamine (if the reaction is allergic) and other mediators, such as cytokines. This response manifests itself, precisely, with the dilation of blood vessels and a rapid swelling.

There are however many cases where hives have not no obvious cause (idiopathic form).

The most common causes of hives can be:

  • a allergic reaction (food allergies, environmental factors such as pollen, drug-induced reactions)
  • theexposure to cold or heat
  • a 'infection, in some infectious diseases, skin rashes can be a symptom or complication
  • il contact with some chemicals found in certain types of foods and medications

Specifically, the non-allergic causes of acute urticaria can be:

  • viral, bacterial or parasitic infections, including sinusitis, fascioliasis, Helicobacter pylori, viral hepatitis (A, B and C), mononucleosis, candida
  • excessive sweating and emotional reaction to the stress
  • external physical stimuli, such as friction or pressure on the skin, water, temperature change, or sunlight.


While chronic urticaria is the result of autoimmune reactions. Though the causes are not entirely clear, it has been shown that it can often arise contextually to other diseases of similar etiology, as:

  • rheumatoid arthritis
  • systemic lupus erythematosus
  • the periodic syndrome associated with cryopyrin

In rarer cases, chronic urticaria can also be caused by:

  • hypothyroidism or hyperthyroidism
  • celiac disease
  • hepatitis or intestinal parasites

Urticaria symptoms and complications

It is clear that urticaria is characterized by the so-called "wheals“, lsimilar to mosquito bites. In general, the symptoms of an urticaria are:

  • reddish bumps, ranging from a few millimeters to several centimeters in diameter
  • pruritus
  • burning or tingling
  • widespread swelling

Many people with acute urticaria and some of those with chronic urticaria are at risk of developing so-called "angioedema”, Which affects different parts of the body, such as eyes, lips and genitals. It is a edema caused by an accumulation of interstitial fluids that occurs at the subcutaneous level or in the submucosal layers. Its symptoms are:

  • burning, heat and pain in the swollen areas
  • swelling of the conjunctiva
  • breathing difficulties

Finally hives can be one of the first symptoms of a severe allergic reaction, the so-called "anaphylaxis”, With dyspnea, weakness and collapse.


In all cases it is always good to consult your doctor.

Hives natural remedies

We have said that in the majority of the times the urticaria regresses spontaneously, without the need for specific treatments or drugs. There are cases, however, in which the dermatosis can be more violent and cause disabling itching attacks. In principle, it is recommended never rub hives affected skin, because rubbing promotes the synthesis of histamine, responsible for the wheals. It may also happen that in some cases the doctor suggests an antihistamine or cortisone therapy.

However, there are effective natural remedies that can greatly alleviate the symptoms of hives, especially when it is mild.

Between these:

  • hot or cold water baths, with baking soda and oatmeal
  • aloe vera, whose gel relieves inflammation and relieves itching
  • essential oil of chamomile, lavender, lemon balm or sandalwood
