Do you sometimes sneeze when you smell flowers with pollens? Do you experience difficulty in breathing when you eat something that you are not allowed to eat? All these are caused by allergic reactions. It is important for you to understand what they are and how they affect your body in order to avoid further problems and serious complications from them.

Why do you get an allergic reaction? The main reason is because your immune system has detected some foreign bodies in your system and it is trying to get it out. That's right. These reactions are the reactions of the immune system to keep the body safe and health. Below are some of the most common ones that you may experience.

The first one is anaphylaxis. This is the reaction that is characterized by shortness of breath. Among all, this is probably the most serious one because it can cause death if not treated immediately. People who have asthma and other allergies that cause them difficulty in breathing such as seafood and peanut allergies should be very careful. They also need to have medications with them all the time to avoid life-threatening situations.

The second one is unconsciousness. Although normally this is not very serious, it can be life-threatening at times. In particular, it can be dangerous if the unconsciousness is brought about by shock. Shock returns to the sudden stoppage of organs from working because of low blood pressure. When organs suddenly do not receive blood from the heart, they will stop working and that can risk your life.

The third one is skin irritation. Many people who have allergies experience skin problems that can be annoying and irritating. Their skin may become red and may itch a lot. Others experience rashes and blistering. Some even have hives depending on the cause.

The fourth one is respiratory problem. This involves the lungs specifically the breathing. Some people feel difficulty in breathing while others cough uncontrollably. Others experience wheezing and tightness around their chest area.

The fifth one is problem in the head area. This allergic reaction does not only pertain to headache but also to problems with the parts of the head. The face and the tongue may swell and the neck may become stiff. Some experience sore throat and other irritations. Some have red eyes or watery eyes.

The sixth one is nose problem. Some allergens cause the nose to become stuff or runny. Others frequently sneeze as a body's response to getting out the allergen outside the nose.

The last one is stomach problem. Among the allergic reactions concerning the digestive system include diarrhea, vomiting and blood in the stool.

If you know these allergic reactions, you can suspect that your condition is caused by allergens. You can then consult with your doctor about the best way possible to over them.
