Luteal rupture may be associated with luteal cysts, increased abdominal pressure, and natural rupture. Self-determination can be made by symptoms such as lower abdominal pain, nausea and vomiting, and bleeding. 1. Luteal cysts: Luteal cysts contain abundant blood vessels on the surface of the ovary, which are more tense, brittle and inelastic. When receiving external force, it may rupture and bleed. Blood accumulates in the pelvic and abdominal cavities and irritates the peritoneum, thus causing pain in the lower abdomen. 2. Increased abdominal pressure: The pressure in the abdominal cavity increases due to coitus, holding back urine, relieving bowel movements, and violent jumping, and the pressure inside the corpus luteum increases, which in turn may cause the corpus luteum to rupture. Symptoms such as abdominal pain, nausea and vomiting may occur. 3. Natural rupture: because of luteal insufficiency, the capillaries within the corpus luteum bleed, once the bleeding is too much, increasing the pressure inside the corpus luteum, the phenomenon of corpus luteum rupture will occur. It is easy to appear on one side of the lower abdomen severe pain, after a short period of time to become persistent pain, accompanied by the symptoms of bleeding. When the luteal rupture occurs with abdominal pain and bleeding, it is necessary to go to the gynecology department of the hospital in time for a comprehensive examination and cooperate with the doctor for treatment.
