## Can dehydration cause vaginal dryness?

Dehydration can add to a general sense of dryness in the body, but here at Alloy, our information points to **low estrogen as the main reason** vaginal dryness happens during perimenopause and menopause. As estrogen drops, the vaginal walls get thinner, less elastic, and less naturally lubricated.

So if you're dealing with vaginal dryness, hydration matters for overall wellness, especially if hot flashes or night sweats are making you lose fluids, but it usually isn't the main driver of vaginal dryness in menopause. If dryness keeps happening, over the counter moisturizers and lubricants can help temporarily, while prescription vaginal estrogen can treat the underlying hormonal change.
