Mae endometriosis yn gyflwr cyffredin sy'n effeithio ar gynifer ag 1 o bob 10 o fenywod mewn oed i gael plant. Er efallai na fydd gan rai menywod unrhyw symptomau amlwg o'r cyflwr, rwyf wedi clywed gan eraill sydd wedi dioddef symptomau sylweddol sydd wedi effeithio cryn dipyn ar ansawdd eu bywydau.
Endometriosis is a common condition that affects as many as 1 in 10 women of childbearing age. Although some women might not have any noticeable symptoms of the condition, I have heard from others that have suffered significant symptoms and impact on their quality of life.
