Asthma is a chronic lung condition, which affects nearly 300 million people across the globe. Sensitive airways in the lungs react to triggers and this causes a ‘flare-up’ leading to tightening of the muscles around the airway. The airways start to swell and become narrow, making it difficult to breathe. If this flare up happens quickly, it’s called an asthma attack. It can also build up slowly over the days.
The likelihood of asthma is increased by the following factors:
A study conducted in 2009 concludes that apart from genetic factors, environmental factors such as infections may increase the risk of asthma in a person. Prenatal risks such as diet and nutrition of the mother, stress, use of antibiotics as well as the mode of delivery of the baby can all be risk factors. In early childhood, things such as exposure to allergens & pollution can also put the child at a risk of asthma.
Gender also plays a role in developing the condition among children. Young boys are more vulnerable to it as their airway size is smaller compared to females. However, after the age of 40, females are more likely to get the condition than males.
