Menopause – menopause in women increases the risk of developing a vaginal itch. During menopause the estrogen levels in the body reduce, resulting in atrophy of vagina. Vaginal atrophy is characterized by thinning and drying of mucosa in the region. When left untreated, dryness of vaginal mucosa irritates the vagina, leading to itching.
Stress – stress, whether physical or mental, may lead to vaginal irritation and itching. This usually happens when the immune system is weakened by stress. It increases the susceptibility of infections in the genital area.
Diabetes – uncontrolled diabetes with high levels of sugar increases the frequency of urination. The risk of vaginal itch and irritation is high in this condition.

In children, pinworm infection may lead to itching and irritation in the vagina. Inadequate cleaning or hygiene of the genital area, particularly in young girls, may make the skin moist in the region. This leads to irritation and itching.
Medical history, symptoms and physical examination are the main diagnostic measures in vaginal itch. The doctor will conduct a pelvic examination to evaluate the health of vulva and the internal organs in the genital area.
A speculum is usually used to check the vagina during a pelvic examination. During the examination, the abdomen is pressed down while a gloved finger is inserted into the vagina.

Blood tests are used to detect conditions like diabetes, kidney disease or liver problems. Patch testing of the skin from the vulval region helps to detect sensitivity to particular chemicals. This will help to identify the irritants of the vaginal skin. In some rare cases, biopsy of vulval skin sample is conducted.
