There are many reasons for allergies, according to your description, you want to know why you are not allergic, but now you are allergic, there are roughly the following reasons:

1. The change of the human body system reduces the resistance.

When the human body is in a weak period, cold and fever and other diseases, the body's resistance becomes poor, and eating some food or touching some objects may cause allergies.

2. Changes in endocrine and hormone levels.

Changes in endocrine and hormone levels can also affect the body's immune system, causing the immune system to respond to stress, which can lead to allergic attacks.

3. The composition of the food may have changed slowly.

Now some fruits may contain some additives, and it may be that these chemical additives are causing you to cause an allergic reaction, not the peaches themselves.

4. Environmental changes.

Changing city life may not only change the climatic conditions, but also the dietary habits and customs have changed, which will cause some unsuitable conditions, which is also a major cause of allergies.

Why do people have allergies? The body's immune system usually reacts with allergies when exposed to certain external substances such as pollen, pet dander, food, etc. These substances are called allergens, and they don't necessarily cause an allergic reaction in all people.

An allergic reaction is essentially a false immune response, in which when the immune system mistakenly identifies these substances as a threat, it releases certain chemicals such as histamine that can cause discomfort or symptoms in the body. Some common symptoms of type 1 allergy include runny nose, sneezing, rash, and shortness of breath.

Allergies are often genetically predisposed, and if someone in your family has a history of allergies, you are at increased risk of developing allergies yourself. In addition, environmental factors such as pollution, chemicals, and personal diet and lifestyle habits can also cause allergic reactions. The best way to be allergic is to identify the allergen and avoid exposure if possible.

For symptoms, methods such as antihistamines can be used.

Children are susceptible to allergies** due to genetic factors, environmental factors, or food allergies.

1.Genetic factors: Some children's allergies are also related to genetic factors, because this is a dominant inheritance, and it is also an irreversible phenomenon, which usually cannot be **.

2.Environmental factors: If the child is allergic, and the environment where he lives is not particularly hygienic, when there is dust or satisfaction, it may lead to allergic reactions, and will also make more small bumps or itching on the top, etc., should stay away from the allergic environment.

3.Food allergies: children's allergies are also related to usual eating, if individuals are allergic to protein, it may lead to allergic reactions in the process of eating milk or eggs regularly, and it will also cause different degrees of harm to their own health, and if necessary, they also need to cooperate with doctors to use anti-allergic drugs**, such as loratadine tablets or levocetirizine hydrochloride tablets.

Children's frequent allergies may be caused by genetic factors, physiological factors, and environmental factors.

1. Genetic factors: allergy is a complex disease with a tendency to be transmitted in families, so the closer the kinship, the higher the prevalence. Chong Heng Song 2, physiological scattered sexual factors:

The child is at the peak of growth and development, and the body's organs and immune cells are not fully developed, so the ability to resist allergies is relatively poor. 3. Environmental factors: For example, there is air pollution, poor living environment, poor air circulation and other phenomena in the place where the child is located, which can easily lead to allergies in the child.

Children with allergies should find out the source of allergies in daily life, if it is because of food allergies, we should pay attention to stay away from allergenic foods, improve eating habits, and eat more nutritious foods that improve physical fitness.
