The vaginal canal and surrounding tissues are estrogen-sensitive. As estrogen levels decline through perimenopause, menopause, breastfeeding, or after certain cancer treatments, the vaginal lining thins, lubrication decreases, and tissue elasticity drops. According to the American College of Obstetricians and Gynecologists, this hormonal shift is the most common reason women develop dryness, irritation, painful intercourse, and recurrent urinary symptoms.
Vaginal childbirth, especially multiple deliveries or larger babies, stretches the pelvic floor and vaginal walls. Some women regain prior tone, while others notice ongoing looseness, reduced sensation, or mild leakage with coughing, laughing, or exercise. Age-related collagen loss and changes in the vaginal microbiome can also play a role. These changes are normal, but they are not something you have to live with quietly.
