I am just 27, and my vaginal walls are lying outward. Why?

Hi,

Welcome to icliniq.com.

I would like to put forth a few features or symptoms to differentiate normal from pathological labial hypertrophy or vaginal wall enlargement.

1. If wall prolapse is painful or tender, associated with excessive vaginal discharge, especially yellow or greenish color, foul-smelling, and itching, and if swelling increases after sexual exposure.
2. Around the time of periods, discharge increases with all the above features associated mild feverish feeling around periods, cramps in the lower abdomen before periods.

All these could be an infection in the vagina following sexual exposure. You need to meet your gynecologist and use medications for yourself and your partner. If the lips of the vagina are not tender and free of the above-mentioned symptoms, then this could be just hereditary, as you mentioned. Then it needs no treatment.
