First things first, what is PCOS?

Despite the name, polycystic ovary syndrome has nothing to do with cysts on the ovaries. The things your doctor saw on ultrasound are follicles or eggs, which are normal for the ovaries. You can have many eggs and still have a normal level of hormones. This is why ultrasounds cannot diagnose (or rule out) the hormonal condition of PCOS.

PCOS is best defined as androgen excess (high male hormones) when all other causes of androgen excess have been ruled out.

To treat PCOS you need to know what’s driving it. In other words you need to know the different types of PCOS.

You could have insulin-resistant PCOS, post-pill PCOS (which is temporary), inflammatory PCOS or the far less common adrenal PCOS.

So, step 1 in determining your PCOS type is to ask “Is it PCOS?”.

do I have PCOS

Is it PCOS?

It’s really PCOS if you have some sign of androgen excess such as:

  • High androgens (male hormones) measurable on a blood test.

  • Facial hair or jawline acne.

AND when other reasons for androgen excess have been ruled out.

Other reasons for androgen excess include certain types of birth control, congenital adrenal hyperplasia (which accounts for up to 9 % of cases of androgen excess) and high prolactin.

Having irregular periods (or no periods) could mean you have PCOS or it could mean you have hypothalamic amenorrhea which is lack of periods due to undereating or under-eating carbs.

The thing to understand is that you can have polycystic ovaries with hypothalamic amenorrhea or under-eating. That means you could have been mistakenly told that you have 'lean PCOS' when you actually have hypothalamic amenorrhea.

For more information read:

  • Maybe it’s not PCOS (and PCOS cannot be diagnosed by ultrasound)

  • Pain is not a symptom of PCOS

  • Is it PCOS or hypothalamic amenorrhea or both?

If you’re certain you have PCOS the next step is to ask "Do I have insulin resistance?".

Insulin-resistant PCOS:

Insulin resistance means having high insulin. It’s also called metabolic syndrome or pre-diabetes. The best way to test for insulin resistance is to measure the hormone insulin (not glucose).

If your insulin is high then the high insulin is driving your androgens and you have insulin resistance, insulin-resistant PCOS.

The treatment of insulin-resistant PCOS is to reverse insulin resistance with diet, exercise and supplements like magnesium and inositol.

Do you have insulin resistance? If you’re thinking “no” then my next question is “are you sure?”

There’s a 70% chance your PCOS is insulin-resistant PCOS.

Did your doctor test for insulin or only glucose or HbA1c? Those tests are not tests for insulin resistance. For more information on insulin testing see Chapter 7 in Period Repair Manual or my insulin blog post.

If you’re certain you do not have insulin resistance let’s move on. Did your symptoms start when coming off the pill?


It’s pretty common to experience a temporary surge in androgens when coming off a drospirenone or cyproterone pill like Yasmin, Yaz, Diane, or Brenda.

Under current diagnostic guidelines that temporary surge in androgens is enough to qualify for the diagnosis of PCOS or post-pill PCOS.

With my post-pill PCOS patients, I recommend the following:

  • Stay calm and know the symptoms are part of a temporary drug-withdrawal process.

  • Consider using a natural anti-androgen supplement like zinc, DIM, or peony & licorice combination for a few months. Read the 7 best natural anti-androgen supplements.

It's possible you have post-pill PCOS if you meet the criteria for PCOS (excess androgen and other conditions ruled out). You do not have insulin resistance and symptoms started when trying to come off the pill.

If you did not just come off the pill or if you had a problem before birth control then let’s move on.

Do you have signs of chronic inflammation?

Inflammatory PCOS:

Chronic inflammation can stimulate the ovaries to make too much testosterone and is a contributing factor for every type of PCOS.

When chronic inflammation is the primary factor it’s inflammatory PCOS.

The treatment for inflammatory PCOS is to identify and correct the underlying source of inflammation.

That could mean avoiding a food sensitivity such as dairy or fixing an underlying gut problem or addressing chronic mast cell activation or histamine intolerance. The supplements zinc and N-acetyl cysteine work particularly well for this type of PCOS.

You have inflammatory PCOS if you meet the criteria for PCOS. You do not have insulin resistance, you’re not in a temporary post-pill phase and you have signs and symptoms of inflammation, as follows:

  • Unexplained fatigue

  • Bowel problems like IBS or SIBO

  • Headaches

  • Joint pain

  • Chronic skin condition like psoriasis, eczema, or hives.

If you do not have signs of chronic inflammation, then let’s move on. Do you have adrenal PCOS?

Adrenal PCOS

Most women with PCOS have an elevation of all androgens including testosterone and androstenedione from the ovaries and DHEAS from the adrenal glands.

If you have only elevated DHEAS (but normal testosterone and androstenedione) then you may have adrenal PCOS. Adrenal PCOS accounts for about 10 percent of PCOS diagnosis.

Adrenal PCOS is not driven by insulin resistance or inflammation. Instead it’s an abnormal response to stress.

Treatments include stress reduction, magnesium, adaptogen herbs (including licorice) and vitamin B5 the “anti-stress factor.”

In addition to treating the underlying cause of your PCOS you may also require a natural anti-androgen supplement.

For information about the 4 types of PCOS and their treatments, see Chapter 7 of Period Repair Manual.

Tip: Thinking you have more than one type? The types are listed in order of priority. So if you have insulin resistance then you have insulin-resistant PCOS — even if you also have inflammation and a post-pill situation.

Still confused?

If you have been told you have PCOS but you do not seem to meet any of the symptoms discussed here?

Go back to the drawing board. Do you truly have PCOS? As in do you have high androgens? Either measurable on a blood test or the clear physical sign of facial hair.

Tip: Your androgen symptoms could be from birth control. Some progestins such as levonorgestrel are very “testosterone-like” and cause acne and hair loss. Read 4 causes of androgen excess in women

If you don’t have high androgens and lack of periods (and maybe mild acne) is your only symptom then you could actually have hypothalamic amenorrhea (look at your luteinizing hormone — it’s high with PCOS and low with hypothalamic amenorrhea.)
