Although ovarian cysts are not a very scary gynecological disease by nature, one of their complications is the rupture of the cyst, which can be very damaging if it ruptures. If an ovarian cyst ruptures, it can cause severe pain in the abdomen, vomiting and nausea, lumbosacral distension, abdominal bleeding, high fever and even shock. When a woman has a ruptured ovarian cyst, she may first experience abdominal distension and pain, but this pain will gradually worsen as the disease progresses and is accompanied by nausea and vomiting. If the ruptured ovarian cyst is not treated promptly and effectively, severe peritonitis may occur, leading to infectious shock and even massive intra-abdominal bleeding, which can be life-threatening. The cause of ovarian cyst rupture may be due to the large size of the cyst, or it may be caused by a violent impact from outside, so women with ovarian cysts should not engage in strenuous sports and heavy physical labor in their daily lives, and they should also pay attention to the strength during sex to avoid strong abdominal impact. Women with large ovarian cysts must pay special attention and seek medical attention if they experience abdominal pain to avoid rupture of the ovarian cyst.
