Diagnosed with PCOS

10 November, 2014


Hi. I was just diagnosed with PCOS. How does this affect my status during niddah?



PCOS (Polycystic Ovarian Syndrome) can present different types of symptoms among women.

Some women experience infrequent periods. There is no halachic requirement to become niddah on a monthly basis. A woman becomes niddah only when she either experiences a flow of blood or finds a stain that meets certain specific criteria.

Another common symptom is irregular staining. It is important to review the laws of stains to prevent becoming niddah unnecessarily from staining. See our article on stains for more details.

If a woman experiences difficulty completing the clean days due to staining, there are a number of suggestions we can offer to help her complete the clean days in a timely manner. Be in touch with us for further guidance if you experience this issue.

Please feel free to get back to us with any further questions.
