What are the characteristics of amenorrhea?

Amenorrhea is the absence of menstrual periods. It is a common problem, affecting up to 5% of women of reproductive age. Amenorrhea can be caused by a variety of factors, including:

* Pregnancy

* Breastfeeding

* Menopause

* Hypothalamic amenorrhea is a type of amenorrhea that occurs when the hypothalamus, a small region of the brain that controls the pituitary gland, does not produce enough of the hormones that signal the ovaries to release eggs. This can be caused by a variety of factors, including stress, weight loss, and excessive exercise.

* Hyperprolactinemia is a condition in which the pituitary gland produces too much of the hormone prolactin. This can cause amenorrhea, as well as other symptoms, such as breast milk production and galactorrhea (leaking of breast milk).

* Polycystic ovary syndrome (PCOS) is a hormonal disorder that can cause amenorrhea, as well as other symptoms, such as weight gain, acne, and hirsutism (excessive hair growth).

* Thyroid problems can also cause amenorrhea. Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can disrupt the menstrual cycle.

* Medications such as chemotherapy, antidepressants, and oral contraceptives can also cause amenorrhea.

* Underlying medical conditions such as diabetes, cancer, and Cushing's syndrome can also lead to amenorrhea.

Amenorrhea can be a sign of a serious underlying medical condition, so it is important to see a doctor if you experience this symptom.
