Seventy-five percent of PCOS patients gain weight, while twenty-five percent are lean.

"75% of them gain weight. 25% of them are very lean." (said at 0:19:40)

While clinical literature commonly estimates that the majority (roughly 40% to 80%) of patients with PCOS are overweight or obese and a subset (often cited around 20% to 30%) have a lean phenotype, no specific fetched record in this search verified the exact 75% versus 25% distribution. Consequently, this precise split remains unverified against the fetched records.

Stromal endometriosis lesions lack glandular structures and consist of connective tissue and nerve endings that cause severe bloating, inflammation, and deeper pain.

"Stromal endometriosis doesn't have the glandular uh lesions with it. It's just these fibers that have nerve endings and the the nerves get squeezed and actually patients with stromal endometriosis tend to have more bloating, more inflammation and more deeper pain." (said at 2:03:41)

The speaker's statement bundles two assertions: 1) Histologically, stromal endometriosis is defined by the presence of endometrial-type stroma without glandular structures, which is well-established in pathology literature (e.g., PMID 19155237). 2) However, the claim that stromal endometriosis consists of nerve-bearing fibers that 'get squeezed' causing patients to experience 'more bloating, more inflammation and more deeper pain' is not supported by published clinical evidence. No comparative clinical studies demonstrate that isolated stromal endometriosis produces more severe bloating, deeper pain, or greater inflammatory symptoms than typical endometriosis.

    "It is generally considered that an unequivocal histological diagnosis of endometriosis requires the presence of endometrioid-type glands and endometrioid-type stroma. However, small nodules or plaques of endometrioid-type stroma without glands have been noticed by the authors in repeated peritoneal biopsies performed for suspected endometriosis... Stromal endometriosis, characterised histologically by small microscopic nodules or plaques of endometrioid-type stroma, sometimes with a whorled pattern and prominent vascularity and erythrocyte extravasation, was identified in 44.9% of the biopsies."

Perimenopause typically begins 7 to 10 years prior to the onset of menopause.

"Seven to 10 years before menopause, women go through perimenopause." (said at 2:27:23)

No matching published records confirming that perimenopause typically begins 7 to 10 years before menopause were fetched within the search queries. In general clinical literature and staging criteria (such as STRAW+10 and SWAN cohort data), the menopausal transition typically lasts an average of 4 to 8 years, though symptoms and subtle endocrine shifts may span a broader range for some individuals. However, without retrieved study records to directly verify or refute the 7 to 10 year claim, this specific assertion remains unverified.

Unverified means no publication matching the claim was located; it does not prove the claim false. Spotted an error? See the corrections policy - disputes from the people quoted are prioritized.
