Irregular Menstruation

Generally, a menstrual cycle lasts about 28 days and provides a wide range of what is considered normal. It is not a cause for concern if it regularly lasts a few days longer or shorter. However, irregular periods occurring at unexpected times, disrupting the menstrual cycle, can be a sign of an underlying different condition.

What Causes Irregular Menstruation?

Besides the variation of the menstrual cycle between 28 to 31 days, there are many factors that can periodically cause irregular periods. Pregnancy, hormonal imbalances, infections, illnesses, traumas, stressful events, intense exercise, long-distance travel, and certain medications are some of the various reasons for irregular menstruation.

Common causes of irregular menstruation include:

• Changing birth control pills or using certain medications.
• Hormonal changes.
• Pregnancy or breastfeeding.
• Eating disorders.
• Excessive exercise.
• Thickening of the uterine lining or the presence of polyps.
• Polycystic ovary syndrome (PCOS).
• Stress.
• Asherman syndrome (scar tissue in the uterine cavity).
• Cushing syndrome (high levels of cortisol hormone).
• Hormonal intrauterine devices (IUDs).
• Problems with the adrenal glands.
• Underactive or overactive thyroid (hypothyroidism or hyperthyroidism).
• Uterine fibroids.

The menstrual cycle is regulated by two hormones called estrogen and progesterone. An excess of these hormones, which regulate the inner lining of the uterus, can lead to heavy bleeding. Both of these hormones can be affected by natural changes in the body such as puberty, pregnancy, childbirth, breastfeeding, and menopause.
