How Allergies Work Inside Body?

Breaking down it step by step that how allergy work inside the body:

• When an allergen enters the body for the first time, an immediate reaction is usually not triggered. Special IgE antibodies are produced by the immune system. These antibodies are attached to cells found in the blood and body tissues. The allergen is then remembered for future exposure.
• When the same allergen is encountered again, it is quickly recognized by the immune system. Histamine and other chemicals are released into the body. As a result, an allergic reaction may be triggered within minutes.
• A few hours later, more immune cells may be attracted to the affected area. Because of this, inflammation may continue. Symptoms may last longer than expected. Conditions such as asthma or eczema may therefore take more time to improve.
• In rare cases, a severe allergic reaction may occur and whole body may be affected. Blood pressure may be lowered and the airways may become narrowed. Breathing difficulties may be caused. This condition is known as anaphylaxis and immediate medical attention should be obtained if it occurs.

How Long Allergies Symptoms Last?

This depends on what triggered things and whether you're still exposed:

• Symptoms from seasonal pollen exposure may last for several weeks or even months. The duration depends on the plants releasing pollen. Symptoms may continue as long as pollen is present in the air.
• When allergies are caused by dust mites or pet dander, symptoms may occur at any time of the year. These allergens are commonly found indoors in all seasons.
• In food allergies, mild itching in the mouth usually goes away within a few hours. Skin reactions like hives or rashes may last for a few hours. Stomach symptoms often improve within 24 hours.
• When the skin is exposed to plants, metals, or chemicals, irritation may develop. Redness and itching may appear. These symptoms often become worst after two to three days. They may last for several weeks.
• Breathing problems from allergic asthma may last a few minutes or several hours. The duration depends on the trigger. It also depends on whether treatment is given.
• In severe allergic reactions, symptoms are usually controlled quickly after treatment. However, another wave of symptoms may appear after a few hours.
• After an insect sting, swelling may appear around the affected area. The swelling is usually highest within 48 hours. It may take up to a week to fully disappear.
• Medication allergies may start within a few hours of taking the drug. Sometimes, reactions may be delayed for several days. Skin rashes may remain for one to two weeks even after stopping the medicine.

Interactions

Certain antihistamines can be affected when they are taken with other medications or substances. Older antihistamines should not be used together with sedatives, opioid medicines or alcohol as excessive drowsiness and other serious side effects may be caused.

These antihistamines should be avoided with MAO inhibitors, a type of antidepressant, because serious effects on central nervous system can occur. Although newer antihistamines are generally considered safer, interactions may still be caused by some antifungal medicines and certain treatments that affect the same enzyme pathways in the body.

Allergy medicines that contain decongestants may also create problems when they are used with MAO inhibitors. For this reason, medical advice should be obtained before allergy medications are taken alongside other medicines, so that potential interactions can be avoided.

Precautions And Safety Warnings

Before start treatment keep these points in mind:

• During pregnancy allergy medicines should be taken with care. Some medicines are safer than others. Medical advice should be taken before starting any treatment during pregnancy.
