This is the permanent station erected only on the lower limbs, the most characteristic of the human species, which is the origin of this disease.
Anthropomorphous apes “pongids” from Africa or Asia (chimpanzee, gorilla, orangutan), without tail, have a skeleton that bares some human resemblance in its morphology. But here the locomotion is most often quadruped while the posture and bipedal walk of these animals are only occasional.
In addition, they are equipped with a particularly strong muscular sphincter and the size of the fetus relative to the size of their pelvis is comparatively much smaller than in women.
All these factors explain why we do not observe genital prolapse among them.
Why do woman present a weakness in this place?
What characterizes our species is that we are bipedal and that humans have permanently liberated their upper limbs for other tasks other than locomotion, which has enabled us to acquire remarkable manual dexterity. It has evolved along with brain development and the development of language.
The development of intelligence has monitored the progress of bipedalism, which however, has not had only fortunate consequences.
By resting the weight of the individual solely on the hip joints, they have been subjected to considerable stress and ultimately has weakened them and made them fragile.
In addition, the decline of the center of gravity in humans compared to animals has projected the resultant force due to the weight of the individual over the basin, including the uro-genital slit which represents an area of weakness, the origin of the pelvic floor disorders that are usually not observed in animal species.
Are there risk factors for occurrence of genital prolapse?
The trauma of childbirth is the most responsible factor for the appearance of genital prolapse in women many years later. It often occurs on this occasion muscles tears that normally support the various pelvic organs. These lesions of the internal musculature can occur even though no tear is visible on the woman’s perineum, and even when preventive episiotomy has been performed.
Other factors may be the cause of the occurrence of genital prolapse, or separately for their own account or their combined effects. These include but are not limited to:
Effects of aging tissues, including the reduction of musculature that interest equally the perineal muscles;
Certain increase in abnormal factors, sudden and significant, of intra-abdominal pressure that we can observe bad sport practice or during certain pathological constipation;
Constitutional abnormalities and congenital bone, particularly around the pelvis, or tissular, focusing in particular on muscles or ligaments, which predispose individuals who are affected by the occurrence of genital prolapse.
Are there warning signs?
It is usually a pain or heaviness in the lower abdomen, in relation to the stretching of the pelvic organs caused by prolapse, which bring the woman to consultations.
In other cases, it is the protrusion from straining then permanent, at the opening of the vagina or vulva bursting out like a ball more or less voluminous in relation the prolapse.
The more or less permanent externalization of this prolapse is a traumatic factor for the tissues that compose it, for the simple fact that they undergo mechanical irritation, which can sometimes be the cause of genital bleeding.
Finally urinary discomfort is also a common cause for consultation: too frequent urination, urgent needs, weakened urine spurts, jerky in several stages.
This difficult urination can cause urinary retention more or less complete in the bladder and therefore distend the urinary tract.
Their origin is not unequivocal.
It can include leakage occurring during a very urgent need felt by the woman. She therefore cannot control urination that occurs explosively.
In other cases, the leaks appear indolent, not preceded by urination and thus represent real incontinence not like the previous case of uncontrolled urination. This type of leak occurs in the day, never at night during sleep, and it is effort that has triggered the occurrence.
This stress urinary incontinence is related to abnormal and excessive mobility of the bladder neck region. It can also be observed in isolation, without being associated with genital prolapse, and in particular to a vesical prolapse.
Often the mechanism of occurrence of leakage in women is mixed, combining leakage in relation to urgent needs and genuine stress urinary incontinence.
Gastrointestinal symptoms related to rectal discomfort are usually rarer and later as the pelvic floor disorder primarily affects the anterior and middle floors of the perineum before degrading the posterior rectal floor.
