Asthma is more generally common in small boys when compared to small girls. But, after puberty, this trend gets reversed. Typically after the age of 20, women are more likely to have asthma than men for the first time. Women are prone to have more problems with asthma, when compared to men. This is primarily due to the hormonal changes during the time of the periods, where women may find an exacerbation of the diseases. Pregnancy also, can worsen asthma, and moreover it can complicate the pregnancy. Between the ages of 20 and 50 women are around three times more likely than men to be admitted for asthma.
Not suffering from asthma during childhood is no guarantee against getting it as an adult. 30 to 40 per cent of people suffering from asthma will get it as adults.
