Why does the vagina suddenly become loose?

We all know that the vagina is very important to women, because it is not only related to women's physical health, but also affects the marriage life of the couple. If a woman has gynecological diseases in her vagina, it is basically impossible to have a normal sexual life. Moreover, many men hate women with gynecological diseases. So, why does the vagina suddenly become loose?

1. Elastic fiber damage

The normal vagina is 2.5 cm in diameter and about 8 cm long. There are many "elastic fibers" on the vaginal wall that support the vagina's elasticity. Countless "elastic fibers" are woven into a dense vaginal elastic fiber network, entangling the vaginal mucosa and many folds, which can increase friction during sexual intercourse and give pleasure to both parties. As you age, the vagina becomes loose due to marriage and childbirth. When the elastic fibers in the vagina break, the vaginal opening expands and the vaginal walls become brittle and thinner, making it easier for bacteria to invade and the vagina is prone to organic damage during intercourse. Due to the rupture and atrophy of the elastic fiber network in the vulva, the sensitivity of the peripheral nerves in the vulva decreases and becomes dull, resulting in sexual indifference, pain during sexual intercourse, etc. The rupture of "elastic fibers" and damage to the elastic fiber network in the vagina are the main causes of vaginal relaxation in patients with vaginal relaxation. When the female vaginal wall is torn or there is frequent strenuous exercise, during sexual intercourse, childbirth, frequent sexual life, abortion, or medical abortion, the elastic fibers in the vagina are "stretched" again and again, the "vaginal elastic network" is broken, and the vagina is stretched and unable to retract, resulting in "vaginal relaxation."

2. Disease population

(1) Women with chronic diseases, weak constitutions, and emaciation have looser muscles, fascia, ligaments, and other structures, which aggravates vaginal relaxation.

(2) Age increase: As women age, their estrogen levels decrease, causing degeneration of muscles, fascia, ligaments and related supporting structures. Muscle tension decreases, fascia becomes thinner, and the vaginal mucosa atrophies, exacerbating vaginal relaxation.
