Understanding PCOS: The Insulin-Progesterone Connection
Did you know that insulin resistance plays a central role in many PCOS symptoms?
Many women with PCOS experience low progesterone levels, but the relationship isn't what you might think. Research shows that insulin resistance and high insulin levels actually CAUSE progesterone deficiency in PCOS—not the other way around. [1]
Here's what happens: When your body becomes resistant to insulin, it produces more insulin to compensate. This excess insulin:
âś“ Stimulates the ovaries to produce more androgens (male hormones) [2-3]
âś“ Disrupts normal ovulation [3]
âś“ Prevents proper corpus luteum formation
âś“ Results in low progesterone production [1]
The good news? Studies show that when insulin resistance is treated, progesterone levels improve significantly. In one study, women with PCOS who took metformin saw their progesterone levels increase from 4.9 to 16.97 ng/ml. [1]
What can you do?
Lifestyle changes are the foundation: [4-5]
• Balanced nutrition (Mediterranean diet, low glycemic foods, high-fiber options)
• Regular physical activity (150+ minutes weekly)
• Weight management when appropriate (even 5-10% weight loss can help)
Medical treatments may include: [4]
• Metformin for metabolic features and insulin resistance
• Individualized treatment plans based on your specific needs and goals
At DNP Wellness Clinic, we understand that PCOS is complex and affects each woman differently. We're here to help you develop a personalized treatment plan that addresses the root causes—not just the symptoms.
