The 4 Types of PCOS Explained: Symptoms, Causes, and How to Support Each Type

Polycystic Ovarian Syndrome (PCOS) is a hormonal disorder among women in which the body produces too many male sex hormones, or androgens. This overproduction is influenced by many factors, including insulin resistance, stress, inflammation, genetics, medication, and more.

Excess androgens can disrupt ovulation, preventing immature eggs from entering the uterus. Instead, the eggs remain in the ovary and form small fluid-filled sacs called cysts (Mayo Clinic).

While 1 in 10 women experience PCOS, it remains under-researched and underfunded, especially in Black women. Knowing the four types of PCOS can make it easier to support your body and advocate for yourself. (OASH)

The 4 Types of PCOS Explained

Insulin Resistance 

As the most common type of PCOS, insulin resistance occurs once the body becomes less responsive to insulin, leading to increased androgen production.

Common symptoms: stubborn weight, intense cravings, extreme fatigue, and infertility

Adrenal 

When the body experiences chronic stress, the adrenal glands can overproduce androgens in response. 

Common symptoms: acne, hair thinning, excessive body hair, irregular periods, and fatigue. 

Inflammatory 

Inflammatory PCOS occurs when the immune system triggers low-grade inflammation, leading to elevated androgens.

Common symptoms: fatigue, stubborn weight, acne,  joint pain, headaches, and digestive issues

Post-pill 

After stopping birth control, women can experience a temporary surge in androgens that mimics PCOS symptoms.

Common symptoms: irregular periods, severe acne, excessive hair growth, and hair loss.(Conlee, MD)

Targeted PCOS Relief 

Since each type of PCOS affects the body differently, targeted support is necessary. Black Girl Vitamins developed PCOS Relief after years of extensive research, focus groups, and chemist formulations. Each ingredient was carefully selected to address the hormonal, metabolic, and inflammatory factors behind each type.

PCOS Relief Ingredient Breakdown

  • Inositol: Supports insulin sensitivity, weight management, hormone balance, ovulation, reduces acne, and excessive hair growth, supporting all types of PCOS.

  • DIM (Diindolylmethane): Helps regulate cycles, hormone surges, acne, and weight gain, most useful for post-pill and adrenal PCOS.

  • Vitamin D: Boosts energy, supports mood, and helps regulate inflammation.

  • Vitamin B12: Helps convert food into energy, supporting fatigue common in insulin-resistant and inflammatory PCOS.

  • Zinc: Supports immune health and reduces inflammation, which can ease symptoms of inflammatory PCOS.
