What happens if the allergy is severe?

Many people in our daily lives are allergic to certain substances. Mild allergies may not pose a threat to your health, but what if the allergy is very severe? Many netizens want to know what will happen if allergies become serious. In order to help everyone better understand the relevant allergy knowledge and better prevent and treat allergies, the following article will specifically introduce the topic of "allergies"!

Allergy refers to the body's abnormal or pathological response to certain substances ( such as bacteria, pollen, food or medicine), situations (such as mental or emotional excitement or exposure to sunlight) or physical conditions (such as cold). When the human body's resistance to antigen invasion is too strong, an allergic reaction will occur under the stimulation of allergens. Generally speaking, when "allergens" enter the body for the first time, mast cells or alkaliphilic granulocytes combine to produce allergic factors such as leukotrienes and prostaglandins, but allergies do not occur immediately. This characteristic will last for 2 to 3 days or even several months. When the body is exposed to this "allergen" for the second time, the mast cells will be deformed and produce allergic factors, which will lead to a series of allergic phenomena.

The damage caused to the body varies depending on the part of the body where the allergy occurs. The most serious allergy is probably the damage to the heart! The relationship between allergies and the heart is that allergies are mainly manifested by damage to the mucous membranes, such as:

1. Allergic conjunctivitis (eye mucous membranes);

2. Allergic rhinitis (nasal mucosa);

3. Asthma (tracheal mucosa);

4. Allergic purpura (skin and mucous membranes);

5. Allergic colic (intestinal mucosa);

6. Purpura nephritis (renal mucosa);

7. The heart has mucous tissue, so the heart will definitely be damaged.

Damage to the heart caused by allergies:

1. Prone to sweating, especially in the first half an hour to two hours of going to bed at night. Some children also sweat easily during their naps.

2. According to the normal laws of the human body, the heartbeat should slow down and energy consumption should decrease after falling asleep. Because the child's heart is damaged, the heartbeat is still relatively fast, which consumes a lot of energy, so he sweats a lot.

3. Easily fatigued and tired. It is manifested in that they like to be held and fall asleep quickly after a long period of activities.
