Some patients are found to have ovarian cysts by ultrasound during physical examination, but after a period of time, the cysts are “missing” on review. Many patients will certainly have questions about what is the reason for this. Will the ovarian cysts disappear on their own without surgery? A: They do disappear on their own. The disappearance of ovarian cysts may be due to functional ovarian cysts or mild inflammatory lesions, which can subside naturally or after anti-inflammatory treatment with herbal medicine. Therefore, it is not surprising that ovarian cysts are not seen on ultrasound after a period of time. What are these “cysts” that disappear of their own accord? Follicular cysts, also known as follicular cysts, are common ovarian cysts. During follicular growth and development, the follicles become atretic or do not rupture, resulting in a buildup of follicular fluid, which in turn causes the follicles to expand, often to a diameter greater than 2.5 cm. Follicular cysts may occur if the patient has menstrual disorders and ovulation disorders, and most of them resolve spontaneously after 2 to 3 menstrual cycles. Luteal cysts Luteal cysts are often single and are associated with persistence of the corpus luteum after ovulation with bleeding and plasma exudation. If ovarian cysts are found on ultrasound during the luteal phase, the possibility of luteal cysts may be considered. The patient should repeat the ultrasound on the 5th to 7th day of menstruation after the next menstrual period or 2 menstrual cycles. If the cyst disappears, it is a functional cyst. Usually luteal cysts disappear within 2 menstrual cycles in non-pregnant women and disappear naturally after 3 months of pregnancy in pregnant women. Inflammatory lesion Mainly refers to infection with pathogenic microorganisms, resulting in an acute attack of pelvic inflammation, which leads to the formation of tubo-ovarian cysts or abscesses. After antibiotic or herbal anti-inflammatory treatment, the cysts may shrink or disappear. Flavin cysts occur in both ovaries, mostly as a concomitant of trophoblastic tumors, and are formed due to large amounts of chorionic gonadotropin stimulation and flavinization of follicular membrane cells. The cysts may subside on their own after clearance of the gravida or after treatment of choriocarcinoma. Doctor’s tip: Don’t be afraid when the cyst comes, don’t panic when the cyst goes, consult a professional doctor and face it rationally is very important.
