Types of Allergy: Allergies develop when your immune system reacts to foreign material- such as pollen, bee venom, or pet dander- or a food that most people do not react to. Antibodies are chemicals created by your immune system.
When you have allergies, your immune system develops antibodies that identify a particular allergen as deadly, even if it is not. When you come into contact with an allergen, your immune system’s reaction may cause inflammation of your skin, sinuses, airways, or digestive tract.

1. Drug allergy

Real medication allergies affect just a small percentage of the population. Most drug reactions are not allergic, but rather a side effects of the medication’s qualities. The patient’s history and symptoms are frequently used to make a diagnosis of the cause of the medication reaction. Skin testing for medication is sometimes performed.

2. Food allergy

Food allergies are caused by your immune system responding to particular foods. Although it is unclear why this occurs, certain foods are more likely to induce an allergic reaction in some persons. One of the most prevalent allergenic foods is Cow’s milk.

3. Insect allergy

The most frequent stinging insects that trigger an allergic reaction include bees, wasps, hornets, yellow jackets, and fire ants. Insects that do not sting can potentially trigger allergic responses. The most frequent are cockroaches and the insect-like dust mite. Allergies to these two insects may be the most common cause of allergy and asthma year-round.

4. Latex allergy

An allergic reaction to natural rubber latex is known as a latex allergy. Natural rubber latex gloves, balloons, condoms, and other natural rubber objects contain latex. A latex allergy can be dangerous to one’s health.

5. Mold allergy

Fungi are mold and mildew. Mold allergies can occur all year since fungi thrive in so many areas, both indoors and outdoors. Coughing, itchy eyes, and other unpleasant symptoms can be caused by mold allergies. Mold allergy medication can help keep allergic reactions under control.

6. Pet allergy

Allergies to furry pets are frequent. It is critical to understand that there is no allergy-free (hypoallergenic) breed of dog or cat. An allergic reaction to proteins contained in an animal’s skin cells, saliva, or urine is known as a pet allergy.

7. Pollen allergy

Pollen is one of the most prevalent seasonal allergy triggers. Many people refer to pollen allergy as “hay fever.” but professionals call it “seasonal allergic rhinitis.”
It happens when allergens, such as pollen, enter your body and your immune system incorrectly recognizes them as a threat. If you have allergic rhinitis, your body reacts to the allergen by releasing chemicals that produce nasal symptoms.

It is a genetic disorder which is inherited from parents to their offspring. This occurs due to gene defect thus causing changes in the protein produced by it. That protein control movement of salt in and out of the cell. A child must inherit one copy of the defective gene from each to have this disease. Cystic fibrosis can cause dire results in the individuals carrying the responsible gene. CF affects secretions of the respiratory, digestive, and reproductive systems. Usually, fluids from the organs are thin and watery, but in patients with possible gene defects, the secretions are thick and sticky. The sticky nature of the fluids clogs the passage of the secretions. 

What is cystic fibrosis? Symptoms, and Treatments

Dr. Sheetu Singh is a leading pulmonologist with great enthusiasm and passion for helping people with respiratory ailments. She explains, in the respiratory tract, if thick mucus gets accumulate, it blocks the airways causing interrupt passage for the exchange of gases. This makes it difficult to breathe for a person.
