A person has allergy when one's immune system reacts to a typically undamaging and harmless substance. There are 2 types of allergies, the perennial type and the seasonal type. The perennial can take place year-round while the seasonal type on the other hand, takes place at a particular time of the year. Effective treatments are available. This includes staying away from specific allergens and also with the help of medication. Symptoms will vary from one person to the other. It mainly depends on what causes it and how severe the reaction is.
There are essentially three primary categories of allergic reactions: mild, moderate and severe. If you are dealing with airborne allergies, sneezing, mild itching, rashes and shortness of breath may take place depending on what is causing a person's allergies. Anaphylactic shock could be an exit if there is a severe reaction. It is a very serious condition and may risk the life of a person. Anaphylactic shock is a condition wherein the airway puffs up close and blood pressure goes down.
Let us focus on airborne allergies for the reason that they are common to a lot of people. Airborne allergies include pollen allergy, pets or dusts and many more. Sneezing, coughing, itchy nose, throat and eyes, conjunctivitis, watery eyes, dark circles visible under a person's eye, and constant upward nose rubbing are some of the most common symptoms of airborne allergies.
Problems breathing can occur when something different takes place in a person who is susceptible and sensitive to substances that may possibly cause an allergic reaction. As soon as the allergen is on the lining of the inside part of a person's nose, chain reaction occurs that causes the mast cell in these tissues to give out histamine as well as the release of other chemicals. These chemicals could lead the cells contained by a number of blood vessels in the nose to contract. When this situation happens, swelling of the nasal passes occurs and nasal congestion takes place. Itching, irritation, sneezing and overload mucus production are some of the causes of histamine.
It is very important to take actions right away when allergy symptoms occur. Knowing the different substances that could possibly cause an potentially severe reaction to your body is also necessary. It is advisable to consult the doctor immediately when allergies get severe. Seek help when the need arises and also before things get worse.
