Introduction
Asthma is a chronic lung condition that can cause difficulty breathing, wheezing, and coughing. It is estimated to affect around 300 million people worldwide. Asthma can start at any age, but it usually begins during childhood. The exact cause of asthma is not known, but environmental factors, such as allergies and air pollution, can play a role in triggering asthma attacks.
What is Asthma?
Asthma is a condition that affects the airways of the lungs. The airways become inflamed and narrowed, making breathing difficult. Common symptoms of asthma include coughing, wheezing, chest tightness, and shortness of breath. Asthma can be mild or severe, and can range from an occasional nuisance to a life-threatening condition.
At What Age Does Asthma Start?
Asthma can start at any age, but it often begins during childhood. It is estimated that up to 25% of children have asthma, and the condition typically begins before the age of 10. Asthma is also more common in boys than in girls.
What Causes Asthma?
The exact cause of asthma is not known. Some researchers believe that asthma is caused by a combination of genetic and environmental factors. Allergens, such as dust and pollen, can trigger asthma symptoms in some people. Air pollution, cigarette smoke, and strong odors can also trigger asthma attacks.
How is Asthma Diagnosed?
If you or your child is experiencing symptoms of asthma, it is important to see a doctor for a proper diagnosis. Your doctor will perform a physical exam and may order tests, such as a chest X-ray, to help diagnose asthma. Your doctor may also recommend an allergy test to identify possible triggers.
How is Asthma Treated?
Asthma is usually treated with medications, such as inhalers or pills. Your doctor may also recommend lifestyle changes, such as avoiding triggers and exercising regularly. It is important to follow your doctor's instructions and take the medications as prescribed. With proper treatment, most people with asthma can lead active, healthy lives.
