What is retrograde menstruation theory?
Retrograde Menstruation. Retrograde menstruation theory is the oldest principle explaining the aetiology of endometriosis. This theory proposes that endometriosis occurs due to the retrograde flow of sloughed endometrial cells/debris via the fallopian tubes into the pelvic cavity during menstruation [18].
What can retrograde menstruation cause?
Retrograde menstruation is when a woman’s menstrual flow moves in the wrong direction. Most women experience this to some extent, but if it’s severe, it can cause pain and may lead to endometriosis.
How does retrograde menstruation cause endometriosis?
In retrograde menstruation, shed tissue flows through the fallopian tubes, enters the pelvic cavity and adheres to tissue in the pelvic cavity leading to formation of ectopic endometriosis lesions.
What are the three hypotheses for the etiology of endometriosis?
Classically, three theories exist to explain the etiology of endometriosis; 1) Sampson’s theory, 2) Meyer’s theory, and 3) Halban’s theory. The most often quoted theory, and to date the one supported by the most evidence, is Sampson’s theory of transplantation and implantation.
How common is retrograde menstruation?
Retrograde menstruation is common, and occurs to some degree in most women who have their period. Despite this, some scientists believe that women with significant retrograde menstruation may be at increased risk for endometriosis.
Is it normal to bleed out your bum on your period?
When you bear down during a poo the muscle contraction may help to move blood through the system and out of the vagina. This increased pressure within the abdomen helps to push out the excrement, and could do the same for any blood that’s left inside the vagina. Like squeezing the excess out of a toothpaste tube!
Does menstrual cup cause retrograde menstruation?
We reviewed the literature and found that few complications other than those associated with incorrect MC positioning have been described. As MCs accumulate blood and may trigger retrograde menstruation, they can theoretically increase the risks of endometriosis or adenomyosis [5].
Where does the blood go with retrograde menstruation?
Retrograde menstruation occurs when blood flows backwards into the pelvis instead of out of the vagina during menstruation. Retrograde menstruation is common, and occurs to some degree in most women who have their period.
Can menstrual cups cause retrograde menstruation?
What are the theories of endometriosis?
Two main theories exist for the pathogenesis of endometriosis. One theory is that endometrial tissue is spread by retrograde menstruation or by vascular and/or lymphatic spread. The second theory holds that the serosal epithelium of the peritoneum undergoes metaplastic differentiation into endometrium-like tissue.
What is believed to be the cause of endometriosis?
The causes of endometriosis are still unknown. One theory suggests that during menstruation, some of the tissue backs up through the fallopian tubes into the abdomen, a sort of “reverse menstruation,” where it attaches and grows.
How is retrograde menstruation diagnosed?
Retrograde menstruation is not usually diagnosed as a condition on its own. It may be diagnosed in the context of endometriosis or pelvic pain evaluation. For example, retrograde menstruation might be diagnosed if healthcare providers do a laparoscopic examination of the pelvis during menstruation and they see blood.
What is retrograde menstruation theory of menstruation?
Retrograde menstruation theory suggest that asynchronous contractions can cause endometrial tissue fragments to flow in opposite (retrograde) direction until they reach pelvic cavity (bottom part of abdominal cavity). This theory is the leading one to explain the cause of endometriosis.
Why does retrograde menstruation cause pain and inflammation?
About Retrograde menstruation. Inflammation is usually to be connected with painful feelings due to higher sensitivity of nerves registering the pain and the swelling causing greater pressure in the area. The temperature increases in the area of inflammation because of increased blood flow. Obviously the intensity of painful feelings corresponds…
How do I treat retrograde menstruation?
Treating retrograde menstruation usually involves prescribing hormones, or a hormonal IUD to reduce or eliminate menstrual flow. A hysterectomy will also treat retrograde menstruation, but would only be used if there were another reason to remove the uterus. Retrograde menstruation may sound scary, but remember that it isn’t all that uncommon.
