Asthma that is caused by things in the environment and not by exposure to allergens is also called intrinsic asthma. The airway becomes constricted and there is inflammation just like allergic asthma, and can also be treated with medication.

This is not to be confused with allergic reactions. Although any age can get intrinsic asthma, it is more commonly found in adults, than children. Combustion engines that emit such gasses as sulfur oxides, monoxide, and nitrogen oxide are said to be common causes of intrinsic asthma. Usually, these byproducts are filtered into the air and play no significance.

An idling vehicle left unattended for a period of time can cause when a person has been exposed for long periods of time, or on a more regular basis. Other causes include tobacco smoke, certain household pollutants, and in kitchens with poor ventilation. Household items with formaldehyde, or air fresheners, perfumes and synthetic fibers found in carpets. Another potential irritant for asthma sufferers are household cleaning products, that affect the airways of the person with asthma.

Although it is rare, other causes of intrinsic asthma include: anxiety, stress, exercise, and hyperventilation. The symptoms of intrinsic asthma are parallel to those symptoms of allergic asthma. Tightness in the chest, rapid and difficulty in breathing and or coughing and wheezing are all symptoms of asthma. By all accounts, it looks just like an allergic asthma attack; the only difference is that it is not caused by the immune system.

It is common for the symptoms to become worse after exposure to cold or dry air, and after exercise. Although there is no cure, knowing what causes these attacks and being able to manage the triggers, can greatly diminish the frequency of these attacks, and help thwart off any future attacks. Certain medicines like bronchodilators and corticosteroids, along with the use of inhalers have proven effective against asthma. There are also unproven treatments such as acupuncture, hypnosis, massage, certain herbs and even the use of a chiropractor to help relieve symptoms.

It is always recommended that you seek the advice of your doctor before trying any time of alternative medicines or therapy. If intrinsic asthma is left untreated, it can lead to permanent damage to the airways, caused by the severe breathing being untreated. Although it is rare, asphyxia and death can occur, but this is been in extreme cases, if the condition is not treated properly.

Intrinsic asthma is controlled easily, in most cases. Through quick diagnosis and proper treatment, a person with intrinsic asthma can lead a long and healthy life, with very few complications.
