Menstruation is a natural monthly cycle that happens to every woman as she reaches puberty. It’s a sign of fertility and it’s an indication that the ovaries are working properly. But there could be times when these cycles become irregular, causing abnormal menstruation.

Here are some of the common causes of abnormal menstruation:


In today’s world, stress has become an inevitable part of our life. Stress is often linked with an irregular menstrual cycle and could make it difficult to conceive. Women who are under a lot of stress due to professional or personal reasons are more likely to miss their periods.

Hormonal Changes

Hormonal changes can cause a variety of problems including irregular periods. When your body is going through certain hormonal changes, the menstrual cycle becomes irregular. This mostly happens during puberty, pregnancy, and menopause stages.


When cells from the lining of the uterus grow outside it and bleed during menstruation, causing pain, cramping, and irregularity in some women. It’s most common in women aged 25-40.

Excessive Weight Gain

Weight gain has been linked with irregular periods in many women. If you have been putting on weight rapidly and also experiencing abnormal menstruation then you should consult a gynecologist immediately to discuss the same.

Polycystic Ovarian Syndrome (PCOS)

PCOS is one of the most common causes of irregular periods in women between 18 to 44 years of age group. Women suffering from this condition have multiple small cyst-like growths in their ovaries which lead to hormonal imbalance and eventually may lead to irregular periods and infertility problems as well.

Eating disorder

Anorexia nervosa is an eating disorder wherein people eat less due to fear of gaining weight and this leads to loss of fat content which is responsible for estrogen production leading to irregular menstruation or amenorrhea in extreme cases. Bulimia is another eating disorder that can cause irregular menstruation.

Extreme Exercise

Excessive exercise can affect ovulation by interfering with the production of hormones needed for ovulation to take place. The more intense and longer exercise sessions become, the more likely your normal menstrual cycle will be affected. This is because your body fat percentage becomes too low and it begins to think that you are starving, leading to a decrease in hormone production.


Dysmenorrhea is painful menstrual cramps that can last throughout the menstrual cycle. This can lead to heavy bleeding and irregular menstruation.


As a teenager, it is common to have irregular periods for the first 2-3 years until your body gets adjusted to menstruating. Similarly, as you approach menopause, your periods may become irregular again as your ovaries get ready to stop releasing eggs.

Sexually Transmitted Diseases (STDs)

STDs such as Chlamydia or Gonorrhea can cause pelvic inflammatory disease (PID) that interferes with a woman’s fertility and causes irregular menstruation. This infection may also cause pain during sexual intercourse.

Inadequate Nutrition

Poor nutrition can lead to anemia, which is one of the most common reasons for irregular periods. When you do not get enough iron, folic acid, and vitamin B12, your body cannot make enough red blood cells that carry oxygen to all its tissues and organs properly. As a result, less oxygen reaches your brain and ovaries, which affects their function. This leads to hormonal imbalance and Irregular Periods.


These are some of the common causes of irregular menstruation. Of course, there could be plenty of other reasons as well. Without thorough examination and diagnosis, it’s almost impossible to underscore the reason behind your irregular period. So, do consult your OB-GYN specialist. Talk to them, discuss your problems, and depending on the diagnosis, start the treatment process early.
