Print Polycystic Ovary Syndrome Symptoms By Angela Grassi, MS, RDN, LDN - Reviewed by a board-certified physician. Updated July 21, 2016 The symptoms of polycystic ovary syndrome (PCOS) are a big part of what makes this chronic disease so confusing. Not only do they differ from woman to woman, but many symptoms, such as fatigue, weight gain, and irregular or painful periods mimic those of many other diseases. Some women with the condition may show no symptoms at all.Because of this, many women with PCOS are misdiagnosed or not diagnosed until symptoms become more severe or obvious to the right doctor. Here are some of the most common symptoms of PCOS.Common Signs and Symptoms of Polycystic Ovary SyndromeMany of the most common signs and symptoms of PCOS are caused by a hormone imbalance. Typically, women with PCOS will have higher levels of male hormones called androgens. Testosterone, for example, is an androgen (yes, women have testosterone just like men have estrogen). This can cause male-like appearance changes such as acne and excess hair growth. Article Unwanted Facial Hair in PCOS Article Is Painless Hair Removal Possible? Too high of androgen levels can also throw off the ratio of female sex hormones, like the ones that control your menstrual cycle.The ovaries overproduce androgens in PCOS, affecting a woman’s menstrual cycle.Insulin is also a hormone that has been shown to be elevated in women with PCOS. Insulin can contribute to weight gain and difficulties losing weight, along with increased risk for metabolic conditions.While signs and symptoms of PCOS vary in type and severity, the ones listed here are the most common ones experienced by women who have the condition:Irregular, Absent, or Heavy Menstrual Cycles Only a small percentage of women with PCOS will have a monthly period. The majority of women experience absent periods for several months or irregular ones that may come two or more times in one month, or occur every other month or so. Some women may have periods that last weeks at a time or they may experience heavy menstrual flow accompanied by blood clots.InfertilityPCOS is the main cause of ovulatory infertility. As a result, women with PCOS tend to face more difficulty conceiving or becoming pregnant. An imbalance of sex hormones can stop ovulation by preventing the maturation and/or release of follicles from the ovaries. The follicles are oftentimes mistaken for cysts.Weight GainCompared to women without PCOS, women with the condition tend to experience higher levels of insulin. Insulin is a growth hormone that promotes weight gain, especially in the central part of the body or abdominal region. Over half of women with PCOS are obese. Having high insulin levels can also contribute to increased cravings and low blood sugar as well as make it difficult for the body to lose weight.

Women with PCOS may experience acne on their face, back, or chest well into adult years. Acne production is usually caused by higher levels of testosterone.Excess Hair GrowthHirsutism, a term for excess hair growth in women, is common in PCOS women. Hirsutism is a result of higher androgen levels, such as testosterone. Typically, there is an increased hair growth in the central part of the body (chest, face, back, lower abdomen, fingers, toes). Some women may experience little to no hair growth at all in these areas, while some women may have a full grown beard.Hair Loss or ThinningHigh levels of androgens can also cause thinning or male-pattern baldness in women. While it’s normal to lose some hair every day, it’s not normal to see a recessed hair line or part or bald patches.Obstructive Sleep ApneaObstructive sleep apnea, commonly characterized by snoring, is highly prevalent in women with PCOS. Sleep apnea may be caused by increased weight as well as increased levels of testosterone, which affect sleep receptors in the brain. Sleep apnea can contribute to insulin resistance and high blood pressure as well as fatigue.Mood Disorders Mood disorders such as anxiety, depression, and bipolar depression are higher in women with PCOS. It is unknown whether this is because of the hormone imbalance seen in PCOS or due to the difficulty of living with this often frustrating and complex condition.Less Common Signs and Symptoms of Polycystic Ovary Syndromehypoglycemiahigh blood pressurehidradenitis suppurativahyperkeratosisfatty livereating disorderspelvic painruptured cystdry skinfatiguedry eyeDiseases and Conditions That Are Similar to Polycystic Ovary SyndromeAgain, there are a lot of different signs and symptoms women with PCOS experience and a lot of them overlap with other medical conditions.
