In fact, these scary-looking rashes are professionally called wheals, which are often manifestations of urticaria. The most common type of wheal that suddenly appears on babies is acute urticaria.

Acute urticaria: appears suddenly and looks scary

Acute urticaria should be considered one of the most common emergency skin diseases among infants and children. More than 80% of patients who visit the dermatology emergency department at night suffer from acute urticaria, especially acute urticaria in children. Because the disease has an acute onset, is particularly sudden, has no signs, and the rash often spreads all over the body, which looks scary, so parents are often very anxious. Going to the emergency room to see a doctor as soon as possible is the natural response of many parents when faced with this common sudden skin disease.

Allergies are indeed one of the most common causes of acute urticaria. Common allergens: Some are in food, and some are in the environment. There are too many and too complicated things in daily life that may contain various allergen ingredients, including food, medicines, air inhalations, contacts, and insect bites. However, the possible allergens for each baby are not the same. Many popular science books simply list a large number of possible allergens from professional books. Parents who are unaware of the truth often blindly avoid this and that, but they still cannot prevent them and are very tired.

Food allergy: True food allergy is actually rare, unless the baby has a hereditary allergic constitution.

How to determine the cause of acute urticaria?

1. Observe whether the baby has symptoms such as cold, tonsillitis, fever, diarrhea, etc. in those days. If the wheal appears with these symptoms at the same time, the cause is often infection;

Most acute urticaria is a transient skin reaction, mainly manifested by itching and swelling, which usually disappears on its own within 1-2 weeks. Although the rash looks scary, it generally does not cause a bad effect on the baby's health and will not leave any sequelae. Don't worry about scars or pigmentation left after the wheal.

However, there are some situations that parents need to pay attention to: if the baby has symptoms of infection such as cold, fever and diarrhea in addition to urticaria, it is necessary to actively go to the hospital to treat the primary infection; if the baby has edema of the eyes and lips, or even difficulty breathing, it is also necessary to go to the hospital for treatment in time, because some severe acute urticaria can cause laryngeal edema, leading to difficulty breathing or even suffocation, endangering the baby's life.
