PCOS and irregular periods

Missed your periods? Beware, it can be a symptom of PCOS! 

Missing periods is like missing a heartbeat. Experts say that one of the common symptoms of PCOS is irregular periods. Even though various other factors could be a reason for your irregular periods, it can also be a warning sign of PCOS which needs to be given immediate attention.  

If you are someone worrying about having irregular periods and wondering if it can be related to PCOS, read ahead to know everything you need to know about the relationship between PCOS and irregular periods.

What is an irregular period? 

Some women think missing periods is what is called irregular periods. But irregular periods are not ONLY missing periods. Below are some of the symptoms to identify that you are facing irregular periods, 

  • Bleeding or spotting between periods 
  • Heavy bleeding during your period 
  • Periods that occur either less than 21 days are more than 35 days 
  • Periods that last more than 7 days or less than 3 days 
  • Very light or no flow during your period 
  • Periods with severe pain in the abdomen with menstrual cramps 
  • Missing three are more periods in a sequence 

These symptoms may vary in every woman. Some women may experience all the symptoms while some may experience a few of them. However, if you are experiencing at least any one of the above symptoms, you are facing irregular periods. And, you need to take immediate action.

How is PCOS related to irregular periods? 

The relationship between PCOS and irregular periods is pretty simple and easily understandable.  

In women with regular menstruation, a matured follicle (containing one immature egg) is released by the ovaries every month. This process is what we call ovulation.  After being released from the ovaries, the eggs reach the fallopian tube and wait there to get fertilized. When these eggs are not fertilized, that’s when menstruation happens. And, the process repeats itself and the cycle continues.  

While this is the normal, regular process of menstruation, let’s see what happens in women with PCOS. The high levels of androgen hormones, which are secreted in women with PCOS, prevent the follicle from maturing while also retaining them in the ovary. This way many such small follicles tend to collect in the ovary. So now, eggs are never released from the follicles and no ovulation happens.  When there is no ovulation there is no menstruation! 

Yes, that’s how PCOS affects your periods!  


These excessive number of follicles, which are air sacs containing the eggs, collected in the ovaries are referred to as cysts that are likely harmless. And now, does it all make sense as to why it is called Polycystic Ovary Syndrome (PCOS)? 

PCOS doesn’t stop with preventing or disrupting your menstrual cycle, it also causes difficulties in conceiving or even infertility in severe conditions of PCOS.

How do you know if PCOS is the cause of your irregular periods? 

This can be a tough task at hand but it is possible. Look, if your irregular periods are combined with other PCOS symptoms like male-pattern hair growth, sudden weight gain, acne or oily skin, dark or thick skin patches on the back of the neck, etc.  

Consulting with a physician and diagnosing for PCOS is also an important step if you are facing irregular periods.
