4 Types of PCOS
September 10, 2018

The previous post about PCOS was about the criteria involved in diagnosing someone with PCOS. Many clinicians follow the Rotterdam criteria, which require 2 out of 3 criteria to be met in order to be diagnosed with PCOS.
They are:
- Delayed ovulation or menstrual cycles (anovulation)
- High androgenic hormones like testosterone
- Polycystic ovaries on ultrasound
The 4 PCOS types

- Polycystic ovaries
Type B

- Anovulation
Type C

- Polycystic ovaries
Type D

Rule these conditions out
Before you jump aboard the PCOS train, you want to rule out certain conditions first, as they may be the cause of some of your symptoms:- High prolactin (found on blood work)
- Hypothalamic amenorrhea
- Hypothyroidism – this can occur with PCOS
- Non-classical congenital adrenal hyperplasia
A note about insulin resistance
As you might have noticed, insulin resistance is predominant in many of the types of PCOS. So how do you measure for it?- Fasting insulin
- Fasting glucose
- Oral glucose tolerance test
