What is PCOS and How Does Diet Help Manage It
Polycystic ovary syndrome (PCOS) affects an estimated one in five Indian women of reproductive age, making India one of the countries with the highest prevalence globally. It is also one of the most mismanaged conditions in Indian healthcare, where treatment often focuses on symptom suppression rather than the underlying metabolic drivers that diet can address directly.
What PCOS actually is
PCOS is a hormonal and metabolic condition characterised by elevated androgens (male hormones), irregular or absent ovulation, and often the presence of multiple small follicles on the ovaries. Its most common symptoms include irregular periods, weight gain particularly around the abdomen, excess facial and body hair, acne, hair thinning, and difficulty conceiving.
The underlying driver in the majority of PCOS cases is insulin resistance. Elevated insulin stimulates the ovaries to produce excess androgens, which disrupts the hormonal balance required for regular ovulation. Addressing insulin resistance through diet is the most evidence-based nutritional intervention for PCOS management.
What to eat for PCOS
Low glycaemic index carbohydrates are the foundation. Replacing white rice and maida with millets, ragi, whole wheat, and legumes reduces insulin spikes and over time improves insulin sensitivity. This directly reduces androgen production and can restore menstrual regularity in women with insulin-driven PCOS.
Adequate protein at every meal further stabilises blood sugar and reduces insulin demand. Dal, eggs, paneer, curd, and roasted chana are practical sources across vegetarian and non-vegetarian diets.
Anti-inflammatory foods reduce the systemic inflammation that is elevated in PCOS and worsens symptoms. Turmeric, ginger, omega-3-rich flaxseeds and walnuts, and a diverse range of colourful vegetables are the most relevant additions.
Methi seeds have specific relevance for PCOS: their galactomannan fibre slows glucose absorption and their diosgenin content has shown preliminary effects on hormonal balance in small studies.
What to reduce
Refined carbohydrates and added sugar drive the insulin spikes that worsen androgen elevation. Dairy is debated in the PCOS context: some research links high dairy consumption to increased androgen activity, though the evidence is not conclusive. Reducing processed dairy while maintaining fermented dairy like curd and chaas is a reasonable middle approach.
The realistic expectation
Dietary changes for PCOS work on a timeline of three to six months of consistent application. They are not a replacement for medical management in moderate to severe cases but are a foundational intervention that improves the effectiveness of any treatment approach.
