Allergic reactions are very common all over the world. In fact, a number of people often are not even aware that they are suffering from an allergy and they think that they are ill. Being able to identify an allergic reaction is essential because every allergy is treated differently. Some reactions can get very serious and can cause a lot of harm to the body so it is important to know how to treat the allergy properly.

What exactly is an allergy? Interestingly, it is our own body which brings about various allergies. Our immune system often can not adapt to certain foreign derivatives. The allergic reaction is due to this immunity system which is trying to throw the substance out of the body. You may have a simple allergy to peanuts or pollen or not even know the exact cause of the allergy. The following reactions are common ways in which the body reacts to substations which do not suit it.

Skin Irritation

Irritation of the skin is one of the most common reactions. You may experience a rash or some kind of swelling, puffiness or marks on the skin. In serious cases you may even get hives all over the skin.

Breathing and Respiratory Problems

Anaphylaxis is the term used for shortness of breath. This condition can get very severe if it is not treated properly. Various medications are available for this and patients often have to be on continuous treatment. Other respiratory problems affect the lungs and can cause wheezing and tightness in the chest. These problems are often thought about by allergic reactions to various foods like peanuts and seafood.


Sudden unconsciousness is just an immediate reaction to something. Very often this is not a very dangerous condition and recovery is quick. The body simply goes into shock for a small period of time. However, you must take it seriously if this happens often since the shock can lead to very low blood pressure and that can cause the organs to stop working.

Stomach Reactions

Ever had diarrhea or constipation after eating a certain type of food? This is often because the food has not reacted well with you. These allergies could also cause blood in your stools or vomiting.

Head and Face Reactions

Sometimes, when you think you've gone in for a common cold, it may not be because of pathogens in the air. Some people suffer from allergies which react in the form of runny noses or stuffiness. In certain cases, the person may also have fits of sneezing in order to try to get rid of the foreign body. Other areas of the head and face may also react. Continuous headaches, stiffness of the neck, swelling of the lips or tongue, watering eyes, a sore throat and other problems often trace back to allergies.

Allergies are often hard to detect because the symptoms are similar to those of several common illnesses. It is necessary to keep a check on what reactions you may suffer from when you eat different foods. Also, always ensure that you have the number handy of a good doctor and a nearby hospital for emergencies.
