PCOS Symptoms

Last Updated: March 17 2022

Polycystic ovary syndrome is a condition causing hormonal problems where small cysts appear on the ovaries.


Polycystic ovary syndrome[1] (PCOS) is an endocrine and reproductive disorder characterized by an excess of hormones that regulate male characteristics (androgens) and ovulatory dysfunction. It affects about 6–20% of pre-menopausal women (depending on how it’s defined; see the sidebar below for more info on the definition of PCOS) and is associated with insulin resistance, dyslipidemia, and visceral adiposity[2] (fat that surrounds vital organs like the liver and intestines). Some of the metabolic consequences of PCOS are depicted in Figure 1.

There is no universal treatment for PCOS. Since PCOS affects endocrine, reproductive, and, ultimately, metabolic health, treatment is individualized to the needs of the patient following first-line therapy[3] that involves lifestyle, diet, and/or exercise modifications. However, beyond energy restriction, no consensus exists for specific PCOS dietary guidelines, as research is quite scarce for this common, yet often scientifically-neglected, condition.
