I've been having itchy rashes lately, and it's annoying to scratch them! Huaxi doctors suggest you check this out...

Some people go out to enjoy the breeze or take a walk.

My face is swollen like an eggplant.

It hurts and itches, how miserable it is

For people with allergies

The air lately is like a "breathing pain"

What are the things that make you allergic?

How to deal with it?

Let me summarize it for you today.

Why do you have allergies? In fact, your body wants to protect you.

When the human body comes into contact with some foreign substances , the immune system will produce some reactants to resist, so as to prevent bad things such as bacteria from entering the body.

However, once this process is "overdone" and too many reactants are produced, your body will suffer. Excessive reactants will trigger an inflammatory response , resulting in allergies.

Many people know the basic principle of allergies, so the root cause of allergies is also very clear. In summary, there are two aspects:

Either the external environment you are in is too complex, and you are exposed to too many miscellaneous "invaders";

Or maybe your immune system is a little messed up and you can't figure out what you should and shouldn't control.

Spring is a high-incidence season for allergies, and foreign substances such as pollen, plant powder, and plant hair contribute greatly to this, but it is also related to everyone's own immunity.

In addition, we need to remind everyone that allergies can cause seeds to grow on the body and cause redness and itching, but these skin symptoms are not necessarily allergies, so you must make a clear distinction.

Strictly speaking, "skin allergy" refers to "contact dermatitis".

Contact dermatitis is an acute or chronic inflammatory reaction that occurs at the contact site of the skin and mucous membranes after contact with certain exogenous substances .

For example, if you come into contact with some irritating strong acids or bases, your face will turn red, which is "irritant contact dermatitis";

Some people also develop rashes and itching after coming into contact with dog hair, catkins, cosmetics and other substances that are usually non-irritating. This is called "allergic contact dermatitis."

Other diseases that may present with similar skin symptoms and lesions include rosacea, urticaria, solar dermatitis, and other diseases.

Many people do not make a clear distinction and regard it as "facial allergy" as long as these symptoms appear on the face. In fact, this is a very broad term.

1. If allergic symptoms occur, go to the hospital in time for treatment and detection of allergens;

2. If allergens can be detected, try to stay away from allergenic environments and take physical protection when necessary, such as wearing masks and gloves;

3. If the accurate allergen cannot be detected, you should actively seek medical treatment and take medication as prescribed by the doctor to avoid worsening of allergic symptoms;

4. Maintain a reasonable diet, exercise more, and keep a good mood to improve your immunity.

One very important point is to detect allergens. There are many people who suffer from allergies in life, but only a small number of people know which substances can cause allergies in them.

Only by figuring out your allergens can you effectively protect yourself and treat them accordingly. As the saying goes, you can't fight a battle you're not prepared for.

Some friends may ask, if I want to check for allergens, I can just go to the hospital and do a blood test to confirm the result. How convenient is that?

Is it enough to check blood for allergens? The answer is No!

For facial allergies, the recommended test is a skin patch test.

Highlight! Important! The skin patch test is the gold standard for diagnosing contact dermatitis in dermatology, similar to this↓↓

After completing the patch test, you can get the result report, which can be used as a guide for substances that need to be avoided in life.

Why else? People change. As you age, your mood, health status and a host of other personal factors change, you might become allergic one day.

The immune system itself has a strong adaptive ability, and it is actually normal for it to constantly change and adjust.

Especially if your daily life is a bit up and down, with high stress, insomnia, and emotional instability , allergies are more likely to occur.

Therefore, regardless of whether you have had allergies before, you should be aware of these symptoms of allergies:

1. Respiratory symptoms such as runny nose, sneezing, coughing, wheezing, chest tightness, etc.;

2. Skin symptoms such as rash, urticaria, skin redness and swelling;

3. Shock of unknown cause.

In addition, there are some symptoms that are very easy to ignore . If they appear for a long time, you should also consider whether they are related to allergies:

1. Frequent drowsiness;

2. Nasal congestion lasts too long (more than one week);

3. Itchy, bloodshot, red, swollen, and tearful eyes;

4. Digestive tract symptoms, including diarrhea, abdominal distension, constipation, bloody stools, abdominal pain, etc. are possible.

If the cause of these symptoms has not been found, the possibility of allergies cannot be ruled out.

In addition, some people may be aware of their allergens and do not see any allergens around them, but still suffer from allergies. In this case, it is very likely that the wind has blown the allergens from somewhere unknown.

Therefore, if you are really allergic to the wind recently, it is best to pay attention to the wind direction to see which direction of wind your body prefers.

Prevention is better than cure for allergies, but if you try your best and still can't prevent it, then you can only say that you are a bit unlucky and you can only actively treat it.
