What is the sensitivity?

Allergy can be defined in general terms as a state of chemical changes that occur as a result of

exposure of the body to external or internal stimuli, leading to a rash, blisters, bubbles, or exfoliation of

the skin and is accompanied by itching or other symptoms depending on the location in which that effect occurred.

What happens to the body as a result of these effects?

 It depends on the strength of the agonist, the extent to which the body reacts to it, and the extent of the immunity and resistance with which the body fights it. 

In this case, the human body’s immune system is represented by its lymphocytes (lymphocytes). 

The stronger the effect, the greater the activity of those cells. 

Lymphocytes may collect outside the blood vessels in order to counteract and fight closely. 

As a result of this conflict between the lymphocytes and the agonist, changes occur that result in the various symptoms of the allergy.

What are the symptoms of an allergy?

 Allergy symptoms are varied and varied, as these symptoms appear on the skin or are accompanied by other symptoms as a result of the impact of internal organs such as the respiratory system.

(A) Acute sensitivity:

Acute allergy symptoms typically occur shortly after exposure to the stimulant.

Its symptoms:

 Redness of the skin and the appearance of blisters or bubbles sometimes, and it may exfoliate, followed by strong itching, and it often affects a large area of ​​the skin. 

Severe skin sensitivity may be accompanied by other symptoms such as a high body temperature and joint pain. 

Acute sensitivity does not last for a long time unless it is accompanied by complications, especially with continued exposure to the stimulus and remains in a process of ebb and flow. 

Sometimes the effect prevails and the acute sensitivity appears, and at other times the body may overcome the sensitivity of the sensitivity.

 But if the effect is less than the first stage and the result is relatively favorable to the immune system, the body's resistance is overcome. 

Therefore, the acute sensitivity begins to gradually subside, as the rash and other associated symptoms such as itching subside.

(B) Chronic allergic reactions:

This type of sensitivity lasts for a long time, and the body remains in a war of controversy and a constant struggle with the external or internal influences. 

Several months or years may pass before the body gets rid of that sensitivity, either by self-effort, or with outside aid, such as taking treatments or refraining from exposure to that effect.

In this type of allergy, the patient suffers from chronic itching, which increases as a result of continuous scratching the thickness of the skin in the affected area, and other symptoms may appear. 

It is possible that the chronic allergy appears from the beginning or it may be a phase following an acute allergy. 

Some types of allergies may have other symptoms, as they may be accompanied by shortness of breath for females in the eye or symptoms of nasal allergy such as persistent sneezing or different symptoms depending on the location of the allergy.

In some cases, the cause cannot be determined, so knowing that the doctor and the patient together may make it difficult, despite the conduct of many laboratory tests or various allergy tests.
