To diagnose PCOS or Polycystic Ovarian Syndrome properly, a woman must undergo comprehensive testing. This condition varies dramatically in its presentation. If severe, there is an excess of ovarian androgens (male hormones), lack of ovulation (anovulation), and polycystic ovaries.
PCOS affects 5% to 10% of females, making it a leading cause of infertility in women of childbearing age.[1,2] However, it does not translate into an ‘infertility sentence.’
With diligent self-care and lifestyle interventions, you can manage your PCOS successfully. But even so, strategic management can only begin if you have been diagnosed with PCOS in the first place.
So in this article, we will discuss the test components of a proper diagnosis and the signs, symptoms, and causes of PCOS. In addition, we will share further insights into its health implications in the long run when left neglected.
Signs and Symptoms of PCOS
The official medical diagnosis of PCOS (or criteria) requires at least two of the following features to be present  :
Multiple ovarian follicles arranged in a pearl necklace shape around the ovaries[1,2]
Oligo-ovulation (irregular ovulation) or Anovulation (lack of ovulation)
Clinical or biochemical evidence of androgen excess.
Clinically, we observe a vast number of signs and symptoms of PCOS that can vary from woman to woman, including the following:
Hormonal imbalances that may include:
Raised testosterone levels
Increased conversion of testosterone to dihydrotestosterone (DHT)
Lower than normal estradiol or estrogen dominance
Reduced sex hormone binding globulin (SHBG) levels
Raised anti-mullerian hormone (AMH) levels for age
Luteinizing hormone (LH) dominance
(Follicle-stimulating hormone or FSH: LH > 1:2)
Hirsutism (excessive or male-pattern hair growth)
Acne and pimples and excessively oily skin or hair
Difficulty losing weight and/or obesity
Longer than typical menstrual cycles (>32 days) due to ovulation occurring later than day 14.
Anovulation (lack of ovulation)
Insulin resistance and blood sugar imbalances that cause symptoms of hypoglycemia
Metabolic syndrome, cardiovascular risks, and hyperlipidemia
It is essential to note that the PCOS symptoms checklist above is only a guide to some women’s experiences and our clinical observations. Not all females have the same presentation of symptoms.
For example, many women diagnosed with PCOS are slim and have no excessive hair growth, pimples, or even cysts in their ovaries. Hence a medical practitioner can often dismiss PCOS if they only look for 2 out of 3 of the medically recognized symptoms. As a result, an estimated 70% of women with PCOS are undiagnosed at any given time.
What Causes PCOS?
There is insufficient general agreement in the literature about the causes of PCOS. However, it is suggested that the condition runs in families and ethnic groups (although a specific genetic link remains to be established).
In addition, environmental triggers are proposed to play a role in developing PCOS :
High carbohydrate intake
Certain nutritional deficiencies.
Fortunately, PCOS prevention is possible by utilizing holistic health management, which is also an essential part of the treatment process.[7,8]
The best way to attain a proper diagnosis is to see a healthcare professional and request blood tests, a pelvic ultrasound, and a revision of your presenting symptoms.
A blood sample collected before 10 am after an overnight fast, preferably performed on day 2 or 3 of your cycle if you are menstruating semi-regularly, would be ideal.
Here are the PCOS diagnosis guidelines or the comprehensive blood work-up list to diagnose PCOS and possible related irregularities:[9-13]
Follicle-stimulating hormone (FSH)
Luteinizing hormone (LH)
Anti-Müllerian hormone (AMH)
Thyroid-stimulating hormone (TSH)
Total and free testosterone
Sex hormone binding globulin (SHBG)
Fasting blood lipids, including triglycerides and high and low-density lipoprotein (HDL/LDL) cholesterol
What Is Expected to Be Found?
The likely findings in women with PCOS (individuals can vary significantly) include[14,15]:
Increased LH: FSH ratio of at least 2:1 (key diagnostic finding in many women)
Usually, elevated total and free testosterone
Generally lowered SHBG.
In some women, results show simultaneously lowered estradiol levels with increased insulin and glucose levels. Moreover, there is an increase in homocysteine, cholesterol levels, and triglycerides for some.[16,17]
But remember that even though some women may not obtain all of the above findings, they may still be diagnosed with PCOS if they have multiple follicles in the ovaries, anovulation or menstrual irregularities, hirsutism, and acne.
Long-Term Health Effects of PCOS
Women with PCOS are more prone to developing insulin resistance, diabetes, cardiovascular disease, and metabolic syndrome later in life if the condition is not managed correctly.[18-20]
Now that you have learned how to diagnose PCOS, we want to emphasize that its symptoms are not precisely ‘curable’ — but relatively manageable.
A natural, holistic treatment approach yields effective results in helping women regulate cycles, lose weight, balance insulin and blood sugar levels, decrease male-pattern hair growth, treat acne, and boost natural fertility. Consequently, all of this help increase your chances of creating the healthiest possible baby.
For some with milder cases of PCOS, symptoms seem to disappear entirely after a period of treatment. But the most effective treatment for the best long-term results involves permanent lifestyle changes supporting optimum general health.
