It is mostly caused by low vaginal secretions, which can affect normal life, such as pain and bleeding during intercourse. There are several common causes of vaginal dryness: first, frequent washing of the vagina in daily life can reduce vaginal secretions and even damage the normal flora. Secondly, if there is inflammation in the vagina, the vaginal environment is changed due to long-term stimulation of inflammation, resulting in congestion, edema and a decrease in normal secretions. If a woman has an irregular diet in her daily life, lack of vitamin B2 in her body can also cause vaginal dryness and in severe cases, ulcers can appear in the vagina. Lastly, women who take hormonal drugs for a long time may have abnormal hormone levels and endocrine disorders, resulting in reduced vaginal secretions and dryness.
