###Human: Can PCOS cause vaginal dryness? ###Assistant: Hi. Although there are multiple reasons for vaginal dryness, the most common among them is deficiency of estrogen, a female hormone. This is possible in your case due to presence of polycystic ovary syndrome (PCOS) which alters the hormonal profile. I will recommend two things which may help you. Firstly, use the topical Estrogen. It is available in the form of gel, ring or cream. As per your convenience you can use either cream or gel and the use of ring requires assistance of doctor. The second thing is stress management. Stress is one of the common reasons for causing decreased vaginal lubrication. Although, there is long list of do's and donot's; principally speaking healthy diet, regular exercise, avoidance of substance abuse, plenty of fluid intake helps most individuals.
