What is PCOS?

PCOS or Polycystic ovary syndrome is a medical condition that impacts a woman’s hormone levels. Keep reading to learn everything you’ve wanted to know about PCOS.

Those with PCOS typically produce more of the male sex hormones which can lead to:

  • Hormonal imbalances
  • Skipped or irregular menstrual periods
  • Difficulties falling pregnant
  • Cysts on your ovaries

Polycystic ovarian syndrome can also cause a range of symptoms including:

  • Excess hair growth (particularly on the face and body)
  • Changes in body shape
  • Acne
  • Balding or excess hair loss

Different types of PCOS

There are four main types of PCOS that we commonly see.

⁠1. Insulin resistant PCOS⁠

⁠This is the most common type of PCOS. We can determine that you have insulin resistant PCOS by looking at your circulating insulin levels.⁠

2️. Pill-induced PCOS⁠

⁠Unfortunately, birth control can mask PCOS and may cause symptoms once we stop taking it. When we cease birth control, there is a flood of androgens which while temporary which can cause a range of symptoms associated with PCOS.⁠

3️. Inflammatory PCOS⁠

⁠Chronic inflammation in our body can see our ovaries produce too much testosterone, which we know is a common issue in PCOS!⁠

⁠4. Adrenal PCOS⁠

⁠If our bodies respond to stress in an abnormal way, we can see adrenal PCOS as a result. It is not as common, only making up around 10% of all PCOS cases. This diagnosis will see high levels of DHEAS (an androgen produced in the adrenal glands) and normal levels of other androgens.⁠

How PCOS is diagnosed

A PCOS diagnosis is typically made by your medical team if you have at least two out of these three symptoms:

  1. Elevated androgen levels
  2. An irregular menstrual cycle
  3. Cysts on your ovaries

Your doctor may also:

  • Conduct a pelvic exam to check the health of your reproductive organs
  • Do an ultrasound to look for abnormal follicles or cysts on your ovaries
  • Take your blood to test your hormones and a variety of other health indicators

Helpful PCOS labs to request

  • Fasting glucose
  • HbA1c
  • Fasting insulin

Inflammation can be common in those with PCOS and thankfully with dietary and lifestyle changes, we can reduce this if we know it is an issue. As your doctor to check your:

How does PCOS impact your cycle?

There are two main ways in which PCOS impacts upon your menstrual cycle.

  1. Women with PCOS typically don’t ovulate or ovulate infrequently. This prevents the uterine lining from shedding each month like we would typically expect. As a result, this can cause irregular menstrual cycles.
  2. As a result of the above, the uterine lining doesn’t shed as often, becomes thicker and can cause heavier bleeding than normal when you do get a menstrual bleed.

Some commonly used supplements include:


The research on magnesium supplementation is not concrete at present. Some studies suggest that magnesium may play a role in improving insulin resistance due to its links to glucose metabolism.


Inositol is often combined with metformin and can help to enhance:

  • Insulin function and manage insulin resistance
  • Move glucose into our cells faster helping to keep our blood sugar levels more stable


Berberine is known for having several functions including:

  • Helping to reduce inflammation
  • Increase insulin sensitivity
  • Encouraging ovulation each cycle (in turn improving fertility)

N-Acetyl Cysteine (NAC)

NAC is an antioxidant compound which reduces the number of free radicals that can damage cells in our body.

NAC is associated with:

  • Improved chances of conceiving
