Jodie Relf’s experience with polycystic ovary syndrome (PCOS) highlights a growing awareness of the role diet can play in managing the condition’s symptoms. Now 38 and a registered dietitian, Relf was initially diagnosed with PCOS in her mid-20s after struggling with irregular menstruation and severe cystic acne following the cessation of hormonal birth control.

PCOS, a hormonal disorder affecting an estimated 3.5 million women in the UK, is characterized by symptoms such as irregular or heavy periods, acne, weight gain, and sometimes excess body hair. Despite its prevalence, recent surveys indicate that nearly half of Britons are unfamiliar with the condition. Relf recalls being diagnosed with little information or guidance, and was simply prescribed the contraceptive pill without discussion of alternative treatments.

While PCOS cannot be cured, experts emphasize that its symptoms can be effectively managed—and in some cases substantially alleviated—through lifestyle changes, particularly dietary modifications. Relf’s journey led her to focus on nutrition as a means of symptom control, reflecting a perspective shared by endocrinologists and researchers who now describe PCOS not only as a hormonal disorder but also a metabolic condition.

Professor Annice Mukherjee, a consultant endocrinologist and visiting professor at Coventry University, explains that PCOS affects blood sugar regulation, which in turn disrupts the reproductive system. Elevated blood sugar levels can lead the ovaries to produce excess testosterone, interfering with ovulation and causing symptoms such as missed periods, acne, and fatigue. Studies show that up to 75 percent of women with PCOS experience this altered blood sugar metabolism. Moreover, women with PCOS face higher risks of developing type 2 diabetes—up to four times greater than those without the condition—and an elevated risk of heart disease.

Dietary approaches that focus on reducing carbohydrate and sugar intake have demonstrated benefits in restoring regular menstrual cycles within weeks. Increasing dietary fiber through fruits, vegetables, legumes, nuts, seeds, and whole grains is also associated with a significant decrease in type 2 diabetes risk in the general population. The NHS recommends a daily fiber intake of 30 grams. Lean proteins such as chicken, tofu, and lentils are likewise advised to help stabilize blood sugar.

Relf advocates a balanced, whole-foods-based diet rather than extreme restriction or meal skipping, which she observes among many women seeking to manage PCOS-related weight issues. Her typical daily meals include high-fiber, protein-rich options such as yogurt with chia seeds and berries, whole grain wraps with chicken and salad, and fish accompanied by lentils and vegetables.

“Simple dietary changes that help maintain steady blood sugar levels can not only alleviate PCOS symptoms in the short term but also reduce the likelihood of severe health complications in the future,” Relf says. Both she and experts alike stress that sustained lifestyle adjustments, rather than short-term fixes or exclusive reliance on medication, offer significant potential for improving quality of life for those affected by PCOS.
