Asthma is a condition in which you have breathing problems, as the airways of the lungs become hypersensitive to irritants.  With asthma, you can experience labored breathing, sneezing, chest constriction, coughing, and trouble breathing.

Asthma can be caused by parasites, usually airborne parasites.

When irritants are in the air, they can enter into the airway, causing the bronchial tubes to swell making it difficult to breath.  The most common type of asthma is asthma that is triggered by allergens like pollen or mold.  Parasites can be tiny organisms that can only be seen under a microscope.  The parasites can be spread through the air, water, food, insects, animals or simply by human contact.  It is usually the airborne parasites that can be related to an asthma attack.

These parasites can enter into the bloodstream and then travel to the muscles and vital organs where they can impose considerable damage on your body.

The parasites begin as very infectious, small and light organisms.  They can float in the air and become inhaled.  Along with asthma, the parasites have been linked to cancer, rheumatoid disease, diabetes, multiple sclerosis, pyorrhea, and other diseases.

While parasites can be inhaled, it is possible that they may be in the body already and still cause sinus problems.  For example, you can have an abscess in your tooth, which holds bacteria and this can lead to sinus inflammation and sinus infections.   Unfortunately, since these parasites are microscopic they can live in the mucus in the sinuses and cause these issues.

Roundworms are the most common infection causing asthma problems.  Roundworms enter the body when a person gets them on their hands and transfers them to their nose or mouth.  Once on the body, the larvae enter the lungs and then the throat, where they are coughed up and swallowed. Once they are swallowed, larvae enter the intestines and become adults, where they can produce eggs for a year or more.  They can be microscopic from 1 millimeter up to 1 meter.  These parasites are most common in warm, tropical climates.

As relates to asthma and your sinuses, the most common signs and symptoms of roundworms is trouble breathing and coughing, along with abdominal problems.

With hookworms, you are also susceptible to asthma problems.  As these parasites cause difficulty breathing, wheezing, coughing and a rash.  A hookworm infection occurs when larvae of the roundworms come into contact with human skin, through contaminated soil or feces. They will penetrate the skin, move through into the lungs to the small intestine, where they attach and mature into adults, laying more eggs. They feed off the blood of the infected person, which can lead to anemia.

While intestinal problems are most common, many of these parasites can cause severe asthma and breathing problems.
