PCOS and Your Weight: Why an Ordinary Diet Isn't Enough — and Saudi Studies by the Numbers

If you're sticking to a diet and the scale won't move, and you have irregular periods, acne and excess hair growth — this article is for you.

How many of us are affected?

Global prevalence among women of reproductive age is estimated at about 6–12%, but studies in Saudi Arabia give higher figures varying by sample and criteria: from 16% in an online survey, to 20–25% in other estimates, up to 32.5% in a study in Madinah^[1],[2].

Why is weight loss harder?

Because the syndrome is characterised by hormonal imbalance and metabolic dysregulation including compensatory hyperinsulinaemia, insulin resistance and dyslipidaemia^[3]. Its metabolic features also include obesity and increased risk of impaired glucose tolerance progressing to type 2 diabetes^[3] — significant in a region that leads the world in diabetes (see the article).

And vitamin D too

A study of Saudi women with PCOS recorded low vitamin D levels^[4] — in a society where deficiency is already widespread (the vitamin D paradox).

What works?

The literature indicates that lifestyle modification may improve metabolic disorders — insulin resistance, glucose tolerance and lipid profile^[5]. Practically:

1. Reduce refined carbohydrates specifically — white rice, white bread and desserts, while raising fibre (why).
2. Resistance training: muscle improves insulin sensitivity directly (details).
3. Realistic goals: even 5–10% of body weight produces a noticeable hormonal difference.
4. Patience is not weakness: your body is working against a hormonal current — compare yourself with yourself, not with a friend.
