Different Types of Asthma
Asthma is a disease of the lungs that affects the bronchial tubes. Unlike other conditions that block the airways, asthma does not affect its victims all the time. There are different types of asthma some of which are associated with the time it starts, for example: childhood, adulthood etc and others are associated with the time of the day that it's worse. There are a number of ways in which asthma can be classified i.e. according to one or more of the following: asthma severity, type of asthma, degree of control etc. Understanding the type of asthma you have can help you look for the most effective treatment for an asthma attack.
The following are the main types of asthma:
- Allergic asthma- Allergies and asthma often go side-by-side. Allergic rhinitis is the inflammation of the inner lining of the nose and is the single most common persistent allergic disease. If you have allergic asthma, you may have a personal or family history of allergies such as allergic rhinitis, hay fever or eczema. The most common allergens enter the body via airway. Seasonal asthma is a kind of asthma that mostly affects people in the spring or early autumn. Other triggers of allergic asthma include respiratory infections such as common cold, flu or sinus infection.
- Nocturnal Asthma- Nocturnal or sleep-related asthma affects people when they are sleeping and asthma symptoms can occur regardless of the time of day a person is sleeping. Symptoms of nocturnal asthma are likely to be the worst between midnight and 4 a.m. About 75% of people with asthma have symptoms that disturb both the length and depth of their sleep at least once a week. Nocturnal asthma can be triggered by allergens in the bedroom, a decline in room temperature and gastroesophageal reflux.
- Exercise-Induced Asthma: Exercise can make asthma symptoms worse. Exercise can trigger asthma symptoms in up to 80 percent of people with asthma. Exercise induced asthma is a very common type of asthma that occurs in both adults and children. Treating and monitoring can allow people with exercise-induced asthma to involve themselves fully in an exercise of their choice.
- Occupational Asthma: Occupational asthma refers to asthma that is diagnosed at a later stage and is caused by an exposure to a substance in the workplace such as chemical fumes, wood dust or irritants over a prolonged period. If you can reduce your exposure to these asthma causing agents, you may be able to reduce asthma symptoms, but occupational asthma does not refer to people already diagnosed with asthma, who are more prone to flare-ups when exposed to irritant dusts or fumes in their work environment. An approximate 15 percent of asthmatics have occupational asthma.
- Steroid Resistant Asthma: Asthma medications, especially steroids are not good. Overdose of asthma medications can result in status asthmatics, which is a severe asthma attack that doesn't react to medication and may involve mechanical ventilation to reverse. To prevent status asthmatics, follow your doctor's directions and take medication as prescribed.
