Why does urticaria grow a lot when my body is hot?

Urticaria is easy to recur because some people are allergic, and the temperature is high in summer, and the skin is easily stimulated. Many things can become allergens. At the same time, improper diet is also an important cause of urticaria recurrence. Because of the hot weather in summer, eating too much irritating food may cause allergies, especially seafood.

Four hazards caused by urticaria:

First, the course of disease is long.

If the early onset of chronic urticaria is not solved, its course will be very long, sometimes as long as several months or even years, and itching will get worse in the morning or before going to bed, which will seriously affect the normal life and psychological state of patients. Therefore, chronic urticaria must be found and treated as soon as possible, rather than let it develop.

Second, it is easy to induce other diseases.

Most patients with chronic urticaria will have digestive tract symptoms such as nausea, vomiting, diarrhea and abdominal pain. Long-term maintenance of these symptoms will lead to ulcerative colitis, which is caused by immune dysfunction, so it can induce visceral diseases, such as autoimmune hyperthyroidism, and even cause cell deterioration. Urticaria in pregnant women can also lead to immune infertility and abortion.

Third, it affects normal life and work.

According to relevant statistics, 95% patients with urticaria think that the disease has an impact on their quality of life. Because urticaria is often accompanied by obvious itching, it will get worse after quiet at night. Repeated scratching damages the skin, and the rash appears repeatedly and persists, which has a great impact on the work, study and life of patients.

Four, serious may endanger life.

The symptoms of chronic urticaria may not be obvious, but we should not underestimate it. Occurring in the throat or bronchus of respiratory tract will lead to recurrent laryngeal edema, such as suffocation, and even symptoms such as shortness of breath, chest tightness, dyspnea, palpitation, irritability and nausea. In severe cases, dyspnea will lead to suffocation and endanger life safety.

Diagnosis and treatment of urticaria;

The diagnosis of urticaria can be made according to the medical history and clinical manifestations, but it is difficult to determine the cause, which depends on detailed medical history, physical examination and necessary laboratory examination. The medical history inquiry should include the following aspects: onset time, duration and frequency of wheal, diurnal variation law, size, shape and distribution of wheal, whether accompanied by angioedema, accompanying symptoms, family history of allergic diseases, whether suffering from internal medicine diseases, infectious diseases, medication history, surgical history, therapeutic effect, personal hobbies, diet, smoking habits, living environment and work type, mosquito bites, female patients and menstrual cycle. In addition, the detection of antinuclear antibody and IgE antibody, and the increase of IgE antibody are also very helpful for the diagnosis of urticaria.

Urticaria is generally treated by systemic therapy, and the release of mediators by mast cells is an important link in the pathogenesis of urticaria. Therefore, inhibiting the release of mediators from mast cells plays a very important role in the treatment of urticaria. Ketotifen is a powerful mast cell stabilizer, followed by antihistamine, which is the first-line treatment of urticaria. For severe acute urticaria, glucocorticoid can be used to control allergic symptoms. Serology showed that immunoglobulin E(IgE) increased. At the same time, Xinmin Kang probiotics were added to reduce serum IgE antibody to reduce the recurrence rate of urticaria. At present, the treatment of urticaria mostly stays in the inflammatory stage such as antihistamine, and some people try to treat it by improving immunity, but allergies are not caused by low immunity. The imbalance of five kinds of immunoglobulin secretion in human body is the fundamental cause of the disease. At present, the treatment method of IgE anti-human antibody to solve urticaria in international immunology research is to reduce IgE antibody in vivo by supplementing Xinmin Kang in large quantities, and to adjust the balance of immunoglobulin by stimulating interferon secretion, thus restoring the immune response of human body. The effective combination of antiallergic drugs and antiallergic probiotics can also produce ideal rehabilitation effect.

How to prevent and care for urticaria in summer?

1, reduce scratching, avoid hot compress and hot bath, although the above practices can temporarily relieve itching, scratching or thermal stimulation will make local blood vessels dilate and exudation increase, thus aggravating the condition of urticaria.

2. Dietary factors are often an important factor leading to recurrent urticaria. After the symptoms of many patients are relieved, they begin to pay no attention to diet and avoid eating, which leads to the recurrence of urticaria. Try to avoid eating fish, shrimp, crab, mutton and other high-protein and spicy, alcohol and other irritating foods.

3, try to find out the cause, and remove it. For example, be careful not to inhale pollen, animal dander, feathers, dust, castor powder, etc., avoid contact with allergens, and ban or fast some drugs or foods that are allergic to the body.
