Adult-onset asthma. Asthma can start at any age, but it’s more common in people younger than 40.
Status asthmaticus. These long-lasting asthma attacks don’t go away when you use bronchodilators. They’re a medical emergency that needs treatment right away.
Asthma in children. Symptoms can vary from episode to episode in the same child.
Exercise-induced bronchoconstriction. You might hear this called exercise-induced asthma. It happens during physical activity, when you breathe in air that’s drier than what’s in your body, and your airways narrow. It can affect people who don’t have asthma, too. You’ll notice symptoms within a few minutes after you start to exercise, and they might last 10 to 15 minutes after you stop.
Allergic asthma. Things that trigger allergies, like dust, pollen and pet dander, can also cause asthma attacks.
Nonallergic asthma. This type flares in extreme weather. It could be the heat of summer or the cold of winter. It could also show up when you’re stressed or have a cold.
Occupational asthma. This usually affects people who work around chemical fumes, dust, or other irritating things in the air.
Eosinophilic asthma. This severe form is marked by high levels of white blood cells called eosinophils. It usually affects adults between 35 and 50 years old.
Nocturnal asthma. Your asthma symptoms get worse at night.
Aspirin-induced asthma. You have asthma symptoms when you take aspirin, along with a runny nose, sneezing, sinus pressure, and a cough.
Cough-variant asthma. Unlike with other types, the only symptom of this kind of asthma is a long-term cough.
