A piece of online news recently circulated. After eating a lobster burger from a fast food restaurant, a netizen woke up from a nap and found that his body was allergic, his body turned red, his trachea swelled and he coughed violently. He had to breathe very hard to get air. Wang Zhengkun, a dermatologist at Yiqun, said that this news has caused panic among allergy patients. According to the allergy photos posted by netizens, they are close to the onset of urticaria. In addition to eating seafood, allergic constitutions also need to prevent food, dust, air, mold, etc. Urticaria may occur due to various reasons, including “bad mood”.
Wang Zhengkun said that there are many causes of urticaria, which are not necessarily caused by food, but can also be caused by infection, drugs, insect bites, pressure, temperature changes, etc. The symptoms are usually local skin redness, swelling, itching or itching, sometimes accompanied by angioedema.
“Dermatographism” refers to using chopsticks to draw lines on the skin of urticaria patients, which will cause redness and swelling, resulting in a strange phenomenon.

Often suddenly, mosquito bite-like bumps appear on the skin, which are extremely itchy; sometimes they quickly spread throughout the body, and even the throat becomes swollen, making it difficult to breathe and inhale air. If even the intestines swell, it can cause abdominal pain or diarrhea.
He said that urticaria is caused by mast cells releasing histamine and other inflammatory mediators, causing dermal capillary leakage, resulting in persistent edema, which will disappear naturally in about a few hours. However, severe cases must be sent to the emergency room to avoid death from breathing difficulties.
This process may be the result of allergic or non-allergic reactions, and the mechanisms that trigger the release of histamine are different. Even “bad mood” can trigger urticaria, and the more you scratch, the more itchy and larger the patches are.
There is a phenomenon called “dermatographism”. If you draw a line on the skin of an urticaria patient with chopsticks, the line will become red and swollen, and sometimes it may feel itchy. When a dermatologist writes words on a patient’s skin, the words will swell, resulting in a very strange phenomenon.
Wang Zhengkun said that avoiding contact with allergens such as food, seafood, fish, shrimps, crabs, shellfish, milk, eggs, peanuts, wheat, and even dust, air, mold, etc. can prevent the onset of urticaria.
Antihistamine drugs or corticosteroids are mainly used to treat urticaria. Patients can prepare oral antihistamine drugs at home and take them immediately in the event of an acute attack. If you continue to have difficulty breathing after taking the medicine, you must seek medical treatment as soon as possible.
