Dr Garba Omale, a Gynaecologist with the Garki Hospital, Abuja, has said ill health, excessive weight and stress are the leading causes of menstrual irregularities. Omale told the News men in Abuja on Friday.He said that menstrual period was usually supposed to last for five to seven days, but in some cases, women suffer menstrual irregularity when their flow deviates from normal.”If a woman’s hormones are not balanced, then, there is problem with the hormones that control ovulation and menstruation which makes the period to be irregular. “If a woman is less than 15 years of age, the first few cycles maybe irregular due to the levels of the hormones being low. So the menstruation can be irregular at the extremes of age. “For women less than 50 years of age and those above 45, hormonal imbalances are common around that age. So it could lead to menstrual irregularity in such women,” the gynaecologist explained. Omale said that menstrual irregularity could also be caused by lifestyle factors such as smoking, stress, or alcoholism. He said that common health conditions such as diabetes, chlamydia, and thyroid disease could also cause menstrual irregularity.
