My daughter was diagnosed with 'severe and extensive' endo at the age of 17 - her Gynaecologist used her photos to show other doctors that it can happen in the younger female, although 14 is very, very young poor lass
Amazingly, despite her notes saying that she had severe disease, trying to get any analgesia when she was admitted to hospital was an enormous fight when she was admitted to other Consultants via A&E!! Twice she discharged herself so she could come home and have some of mine!
She was advised to have her children before the age of 25 if she wanted them and this she has done. The next battle will be getting a hysterectomy at such a young age, but I do think if she can see her Consultant, he will do it .....
I have Adenomyosis, which is the same but is retained in the uterus - I had an ablation and a Mirena fitted and went through the Menopause without incident fortunately! My Mum has Endo with no symptoms, it was found incidentally and we think my other daughter may also have it as well - nasty disease
