Some issues Dr. Gil Guevarra Magpantay, MD can help you with:

Asthma

Asthma is a chronic lung disease where the tissue and airways of the lungs become extremely sensitive to certain substances. When these substances are breathed in, the lungs become inflamed. The muscles around the airways tighten and squeeze the lungs, and passages within the lungs swell and tighten. The airways themselves produce mucus, which further clogs the tightened, swollen airways. A person having an asthma attack finds it very difficult to breathe, and a severe attack can even be fatal.

Asthma affects people of all ages, but people with asthma are most often diagnosed as children. Symptoms can include wheezing, a tight feeling in the chest, shortness of breath, and coughing. Some people have mild symptoms all the time, and some people have no symptoms at all, but everyone with asthma is susceptible to occasional severe attacks or flare-ups of symptoms when they are exposed to triggers. Triggers vary widely but can include:

  • Allergens (dust mites, pet fur, mold, pollen, grass)
  • Irritants (smoke, pollution, dust, chemicals)
  • Viral infections
  • Physical activity, especially outdoors
  • Certain medications or chemicals in foods (aspirin, sulfites)

Treatment for most asthma patients involves three steps. Patients learn what their asthma triggers are and avoid them. They take a daily control medication, usually an inhaled corticosteroid, to reduce inflammation in the lungs. Also, they have rescue medication with them at all times to take in case of a severe attack. These quick-acting inhaled medications relax the muscles around the airways and allow the lungs to open up for air.

There is no cure for asthma, but with treatment it should not interfere with daily life and activities.

Subcutaneous Allergen Immunotherapy (Allergy Shots)

Also known as allergy shots, subcutaneous allergen immunotherapy is a treatment in which gradually increasing doses of an allergen are injected under the skin. An allergen is a substance that can bring about an allergic reaction. Pollen, dust mites, and pet dander are the most common examples of these substances. When patients receive an allergy shot, their body produces "blocking" antibodies that decrease the immune system's sensitivity to an allergen, thus reducing their symptoms.

Before treatment is begun, patients and their doctors first have to identify different factors that trigger their symptoms. Then, skin tests are done to confirm which substances cause allergic reactions. Blood tests may be performed as well, but they are typically not necessary.

There are two phases to subcutaneous allergen immunotherapy: a build-up phase and a maintenance phase. The build-up phase lasts three to six months, during which patients receive shots with increasing amounts of the allergens once or twice a week. When the effective dose is reached, the maintenance phase begins and may continue for up to five years.

Although allergy shots are the longest-lasting and most effective allergy treatment available, they are not for everyone. If patients have heart problems, high blood pressure, or severe asthma, they should not be given allergy shots. The injections are generally safe, but they may have a little swelling at the injection site, which is normal. Rarely, severe shock-like reactions, called anaphylaxis, can also occur. Patients will likely be required by their doctor to stay for half an hour after their shot, so in the event of an anaphylactic reaction, it can be treated immediately.
