Swedish scientists have reported that asthmatic women have tendency of irregular menstruation.
Irregular menstruation is often caused by polycystic ovary syndrome, severe stress, serious disease, anorexia nervosa, and drug addiction. Researchers have followed up the health records of 8588 women for 8 years to understand the possible link between asthma and irregular periods.
The results of the research said that younger women with asthma and allergies are more likely to have irregular periods than older women. The authors suggest three possible reasons for such association. Firstly, asthma medication may cause disturbances in the menstrual cycle. Secondly, irregular menstruation and its treatment may cause asthma. And thirdly, common etiological factors may trigger both asthma and irregular menstruation.
Researchers of the study feel that female sex hormones play an important role in linking asthma and allergy with irregular menstruation.
The authors feel that the underlying metabolic condition that may trigger both the conditions may be insulin resistance. This could not only explain the relationship between asthma and irregular periods, but also the complex and contradictory findings related to asthma and other aspects of hormonal conditions in women.
