There are many severe allergies and symptoms that affect up to thirty percent of the population. Young adults and many children experience hay fever, or allergic rhinitis. Allergic rhinitis can be one of many severe allergies that causes inflammation and irritation of nasal passages from year round and seasonal allergens. Symptoms include but are not limited to nasal congestion, post nasal drip, itching of the nose and sneezing.
There are some who think that allergic rhinitis is not a big deal, but for those who suffer greatly through this allergy; it can be a horrible nightmare. Allergic rhinitis can be classified with other severe allergies affecting the majority of the population, causing missed work days and school days. With the combined costs of doctors’ visits, missed work days and medical; this has indeed taken a heavy toll on a person who suffers greatly from this allergy. You could actually compare their quality of life to that of a person who suffers from severe asthma.
Unfortunately; allergic rhinitis is one of those severe allergies that possibly influence other diseases. When hay fever symptoms are not controlled, sinus infections, asthma, and ear infections are an end result. Those who suffer from allergic rhinitis are more prone to illnesses because inflammation of the nose causes the person to become much more susceptible to virus causing the common cold.
There a many reactions that accompany severe allergies. Type I reaction is a result when antigens attaches to IgE antibodies stimulating mast cells to release histamines with other chemical culprits of the allergy. Certain types of reactions can cause welts, wheezing, itching, and sneezing. Severe allergies can cause nasal obstructions, facial pain and pressure. Other severe allergies are related to shell fish. These are activated by IgE; symptoms of this include wheezing, itching, hives, and in most instances, death.
Other severe allergies include Type IV delayed hypersensitivity reaction. Mediated by a person’s lymphocytes usually occurs several days after exposure and can quite possibly last for twenty – one days. Symptoms include intense itching, deep blisters and a skin rash.
One of the most notorious, severe allergies is anaphylaxis. This allergy is a life threatening reaction caused when mast cells releases chemicals such as leukotrienes and histamines. A person will experience lowered blood pressure, which basically shocks the system. Other horrifying symptoms include hives, swelling, and breathing problems. Other symptoms include:
- Rapid heart rate
- Vomiting
- Diarrhea
- Abdominal cramping
- Rapid heart rate
Shellfish can usually contribute to anaphylaxis. Skin testing and blood tests can be performed to track down the specific allergen that causes this type of allergy. A person could be allergic to shrimp, but not have a problem when eating a clam or a mussel. In order to confirm severe allergies, blood tests can be utilized by checking the serum tryptase level, just to make sure that a disease similar to anaphylaxis is not the culprit to the symptoms.
