There are many causes that can lead to vaginal dryness and the treatment varies depending on the cause. First of all, when the body is deficient in vitamin B2, it tends to cause abnormalities in the metabolism of the mucous membrane cells in the cavity. In this case, you can take vitamin B2 to relieve it, or you can eat foods containing vitamin B2, such as egg yolk, mushrooms, nori, oranges and oranges. Secondly, lack of estrogen in the body can also cause vaginal dryness when there is an endocrine disorder. You can take estrogen supplementation drugs such as estradiol valerate tablets combined with estrogen tablets under the guidance of a doctor. Then, if you have vaginitis, the vaginal dryness will naturally improve with timely treatment of vaginitis. Topical medications, such as testosterone ointment and topical androgens, can also be used.
