Polyendocrine metabolic ovarian syndrome in pregnancy: pathophysiology and outcomes.
Narrative ReviewReview2026
In women with PMOS, their bodies have trouble managing sugar and hormones, which makes them more likely to gain weight — so the weight gain isn’t just random, it’s a sign of their metabolism being out of balance.
Narrative ReviewReview2026
Even when women with PMOS aren't overweight, their bodies are already struggling with sugar metabolism, which can lead to weight gain later. So weight gain isn't just from eating too much—it's tied to broken metabolism.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
The body becomes less responsive to insulin, causing the pancreas to produce more insulin. This excess insulin forces the ovaries to make too many male hormones and stops the liver from making a protein that binds those hormones, leaving more active hormones in the blood. These high hormone levels prevent normal fat breakdown and cause fat to accumulate, especially around the abdomen, leading to weight gain.

We isolate the claim
Health advice from videos, articles and studies is broken down into single, testable claims.
- 2
We find the research
Each claim is matched against peer-reviewed studies, with every source cited by DOI.
- 3
We grade the evidence
Studies are scored on methodology, statistical rigor, transparency and publication quality.
The fitness and health internet is full of confident claims. We check them against real research.
Every claim on this site is traced back to peer-reviewed studies, scored on methodology and reporting quality, and given a verdict you can audit yourself — sources, DOIs and all.
