Ovarian chocolate cysts are a type of endometriosis and can cause pain in the small abdomen, most notably during menstruation, when the pain in the small abdomen worsens, and often cause infertility or irregular vaginal bleeding. Once this condition is detected, it is given prompt treatment, preferably surgery for treatment. If surgery is not done, as the ovarian chocolate cyst increases in size, there is a risk of rupture, which could have unthinkable consequences. A ruptured chocolate cyst will allow the endometrium within it to implant in various locations in the pelvis, causing severe clinical symptoms. Therefore, once a chocolate cyst is detected, it is best to go to the hospital for surgical treatment 3-7 days after menstruation.
