An Allergy arises in the body when it produces an immune response to things such as cats or pollen that don’t affect most people. If you get too close to something that you’re allergic to (also called an allergen), you may experience symptoms like sneezing, shortness of breath, and itchy, watery eyes.
Approximately 60 million Americans suffer from allergic diseases. Allergic diseases, such as allergic rhinitis (hay fever), food allergy, and atopic dermatitis (eczema) are common among all age groups in the United States. Allergies can also play a major role in serious conditions like asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening reactions called anaphylaxis. Food allergies and reactions to the venom of stinging insects (wasps, bees, and hornets) are often associated with these severe reactions. On average, most people are allergic to 2 or 3 sources.
CAUSES OF ALLERGY
Allergy is something your body is not tolerating.so when your body is not able to tolerate that means your immunity has gone down so to cure allergy its not only anti allergens will help you to get permanent solution you need to cure or improve your immunity.pillars on which immunity is based on healthy lifestyle healthy nutrition,with good excercise.
People who have asthma will experience the worst of their symptoms during asthma attacks. In the throes of an asthma attack, the breathing passageways become so inflamed that they are swollen almost shut in some cases. Trying to breathe under these circumstances is extremely difficult and the asthma sufferer will often start wheezing, gasping for air, and coughing during the attack. Because the feeling of not being able to breathe freely is a very frightening one, it is not unusual for asthma sufferers to feel panicked during an attack. During an asthma attack, some people feel pain in the chest as a result of the constant struggle to draw air.
An allergen is an otherwise harmless substance that causes an allergic reaction. Allergic rhinitis, or hay fever, is an allergic response to specific allergens. Pollen is the most common allergen in seasonal allergic rhinitis. These are allergy symptoms that occur with the change of seasons.
Nearly 8 percent of adults in the United States experience allergic rhinitis of some kind, according to the American Academy of Allergy, Asthma & Immunology (AAAAI). Between 10 and 30 percent of the worldwide population may also have allergic rhinitis.When your body comes into contact with an allergen, it releases histamine, which is a natural chemical that defends your body from the allergen. This chemical can cause allergic rhinitis and its symptoms, including a runny nose, sneezing, and itchy eyes. In addition to tree pollen, other common allergens include:
A sinus infection is an inflammation of the tissue that lines the sinuses. It occurs when the sinuses become blocked. They can be filled with fluid, bacteria, viruses, and/or fungus can grow and cause an infection.
Sinusitis has many causes which may include, among other things, a viral infection, common cold or allergies.
Symptoms of sinus infection include headache, nasal congestion/discharge, postnasal drip, sore throat, fever, fatigue, facial pain/pressure, bad breath, and loss of smell. Any or all of these may be experienced.
Pharyngitis is inflammation of the pharynx, which is in the back of the throat. It’s most often referred to simply as “sore throat.” Pharyngitis can also cause scratchiness in the throat and difficulty swallowing.
According to the American Osteopathic Association (AOA), pharyngitis-induced sore throat is one of the most common reasons for doctor visits. More cases of pharyngitis occur during the colder months of the year. It’s also one of the most common reasons why people stay home from work. In order to properly treat a sore throat, it’s important to identify its cause. Pharyngitis may be caused by bacterial or viral infections.The length of the contagious period will also depend on your underlying condition. If you have a viral infection, you will be contagious until your fever runs its course. If you have strep throat, you may be contagious from the onset until you’ve spent 24 hours on antibiotics. The common cold usually lasts less than 10 days. Symptoms, including fever, may peak around three to five days. If pharyngitis is associated with a cold virus, you can expect your symptoms to last this duration of time.
Laryngitis is an inflammation of your voice box (larynx) from overuse, irritation or infection.
Inside the larynx are your vocal cords — two folds of mucous membrane covering muscle and cartilage. Normally, your vocal cords open and close smoothly, forming sounds through their movement and vibration.
But with laryngitis, your vocal cords become inflamed or irritated. This swelling causes distortion of the sounds produced by air passing over them. As a result, your voice sounds hoarse. In some cases of laryngitis, your voice can become almost undetectable.
Laryngitis may be short-lived (acute) or long lasting (chronic). Most cases of laryngitis are triggered by a temporary viral infection or vocal strain and aren’t serious. Persistent hoarseness can sometimes signal a more serious underlying medical condition.
Tonsillitis is inflammation of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side. Signs and symptoms of tonsillitis include swollen tonsils, sore throat, difficulty swallowing and tender lymph nodes on the sides of the neck.Most cases of tonsillitis are caused by infection with a common virus, but bacterial infections also may cause tonsillitis.Because appropriate treatment for tonsillitis depends on the cause, it’s important to get a prompt and accurate diagnosis. Surgery to remove tonsils, once a common procedure to treat tonsillitis, is usually performed only when bacterial tonsillitis occurs frequently, doesn’t respond to other treatments or causes serious complications.
Bronchitis is an inflammation of the lining of your bronchial tubes, which carry air to and from your lungs. People who have bronchitis often cough up thickened mucus, which can be discolored. Bronchitis may be either acute or chronic.
Often developing from a cold or other respiratory infection, acute bronchitis is very common. Chronic bronchitis, a more serious condition, is a constant irritation or inflammation of the lining of the bronchial tubes, often due to smoking.
Acute bronchitis, also called a chest cold, usually improves within a week to 10 days without lasting effects, although the cough may linger for weeks.
However, if you have repeated bouts of bronchitis, you may have chronic bronchitis, which requires medical attention. Chronic bronchitis is one of the conditions included in chronic obstructive pulmonary disease (COPD).
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing. It’s caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. People with COPDare at increased risk of developing heart disease, lung cancer and a variety of other conditions.
Emphysema and chronic bronchitis are the two most common conditions that contribute to COPD. Chronic bronchitis is inflammation of the lining of the bronchial tubes, which carry air to and from the air sacs (alveoli) of the lungs. It’s characterized by daily cough and mucus (sputum) production.
Emphysema is a condition in which the alveoli at the end of the smallest air passages (bronchioles) of the lungs are destroyed as a result of damaging exposure to cigarette smoke and other irritating gases and particulate matter.
COPD is treatable. With proper management, most people with COPD can achieve good symptom control and quality of life, as well as reduced risk of other associated conditions.
