Asthma is a complex disease with numerous subtypes and variations. While there is no universally accepted classification system that defines three distinct types of asthma, clinicians may refer to different categories based on specific characteristics and triggers. Here are three common ways asthma is sometimes categorized: It’s critical to understand that asthma is a highly individual condition, with many people experiencing a mix of allergic and nonallergic triggers. Furthermore, the severity of asthma can range from mild, intermittent symptoms to severe, persistent asthma. As such, healthcare providers typically evaluate each person’s asthma on a case-by-case basis, taking into account their unique symptoms, triggers, and response to medications, to develop a personalized asthma management plan.
