An allergic condition


It is the appearance of signs and symptoms in your body. Most common symptoms that you will see effects this area;

  1. Nose
  2. Sinuses
  3. Lungs
  4. Eyes
  5. Skin

In addition to this, there are some severe cases in which the person has an impact on his blood vessels. So if some allergy is affecting your skin, digestive system, and blood vessels, it can become deadly.

The appearance of signs and symptoms (the time it takes to show)

The appearance of allergic signs varies. Some allergies show immediate signs while others appear over time.

1. Immediate reactions

Immediate reactions

The allergies that show immediate reactions are usually mild ones. For example, if you have a pollen allergy, you will show symptoms in a few minutes. So if you get in contact with your allergen it will show signs in a few minutes.

The reason for a delay in the appearance of signs also varies from person to person. It depends on your genes and also the affected body parts. If you have a serious allergy, you will show an immediate reaction and the reaction might be severe too.

However, the severity of the reaction depends on some other factors. Some people have a weak immune system. Therefore, they show a severe reaction to allergens.

Some of the early reactions to allergens include;

  1. Anaphylaxis
  2. Swelling
  3. Vomiting
  4. Diarrhea
  5. Hives
  6. Asthma
  7. Allergic rhinitis

2. Delayed reactions


These reactions occur after around 2 to 6 hours of exposure. The time can exceed depending on the immunity of the person and the severity of the allergic condition. Signs and symptoms are usually the same in both reactions.

Some of the signs of late reactions include;

  1. Labored breathing
  2. Swelling
  3. Pain
  4. Skin redness
  5. Warmth

The signs appear late because the mast cells keep on attracting the inflammatory cells. Thus, the inflammation appears late.

Which one is more dangerous?


However, late reactions sometimes lead to dangerous situations. If you immediately detect your allergic reaction, you will be able to reach the hospital on time.

For example, if you are allergic to peaches and you accidentally intake them in a drink. You are not aware that the drink has peach juice. If you get an immediate reaction, you can know that it is because of your allergy. Or you can ask the waiter if the drink had peach juice.

However, if you get a late reaction, you won’t be able to tell why you are feeling that way. If you feel suffocated, you might not consider your allergic reaction. Moreover, if you are alone at your home and you passed out because of your allergy, there won’t be anyone to take you to the hospital.

Therefore, you must know your condition. If you get immediate signs, it won’t be much problem for you. On the other hand, if you get delayed symptoms, you should be very careful with your food and your surroundings. You need to make sure that you do not get in contact with your allergens.

Or the least you can do is to keep someone by your side. So even if you are not feeling okay, they know what to do. Imagine someone with allergic asthma home alone. If that person passes out at night because of his asthma and no one notices, it will become deadly for him.

But this does not make early symptoms less dangerous

Even with early signs, some reactions can be fatal. For example, anaphylaxis. It results in anaphylactic shock that results in dropping your blood pressure. Eventually, your lung muscles will constrict and there will be swelling in your lungs that can block the airways.

Therefore, it is best to get timely treatment. If you have such a severe allergy, you should tell your nearby people so they can call for an ambulance on time.
