overview Amenorrhea (uh-men-o-REE-uh) is the absence of menstruation — one or more missed menstrual periods. women who’ve missed at least three menstrual periods in a row have amenorrhea, as do ladies who have not started menstruation by age 15.
The most common cause of amenorrhea is pregnancy. other causes of amenorrhea encompass problems with the reproductive organs or with the glands that help regulate hormone levels. treatment of the underlying circumstance often resolves amenorrhea. signs and symptoms
the principle sign of amenorrhea is the absence of menstrual periods. depending on the cause of amenorrhea, you might experience other signs or symptoms together with the absence of periods, which include: Milky nipple discharge Hair loss Headache vision changes excess facial hair Pelvic ache acne Causes Female reproductive organs Female reproductive system Amenorrhea can occur for a variety of reasons. Some are normal during the course of a woman’s life, while others may be a side effect of medication or a sign of a medical problem. Natural amenorrhea During the normal course of your life, you may experience amenorrhea for natural reasons, such as: Pregnancy Breast-feeding Menopause Contraceptives Some women who take birth control pills may not have periods. Even after stopping oral contraceptives, it may take some time before regular ovulation and menstruation return. Contraceptives that are injected or implanted also may cause amenorrhea, as can some types of intrauterine devices. Medications Certain medications can cause menstrual periods to stop, including some types of: Antipsychotics Cancer chemotherapy Antidepressants Blood pressure drugs Allergy medications Lifestyle factors Sometimes lifestyle factors contribute to amenorrhea, for instance: Low body weight. Excessively low body weight — about 10 percent under normal weight — interrupts many hormonal functions in your body, potentially halting ovulation. Women who have an eating disorder, such as anorexia or bulimia, often stop having periods because of these abnormal hormonal changes. Excessive exercise. Women who participate in activities that require rigorous training, such as ballet, may find their menstrual cycles interrupted. Several factors combine to contribute to the loss of periods in athletes, including low body fat, stress and high energy expenditure. Stress. Mental stress can temporarily alter the functioning of your hypothalamus — an area of your brain that controls the hormones that regulate your menstrual cycle. Ovulation and menstruation may stop as a result. Regular menstrual periods usually resume after your stress decreases. Hormonal imbalance Many types of medical problems can cause hormonal imbalance, including: Polycystic ovary syndrome (PCOS). PCOS causes relatively high and sustained levels of hormones, rather than the fluctuating levels seen in the normal menstrual cycle. Thyroid malfunction. An overactive thyroid gland (hyperthyroidism) or underactive thyroid gland (hypothyroidism) can cause menstrual irregularities, including amenorrhea. Pituitary tumor. A noncancerous (benign) tumor in your pituitary gland can interfere with the hormonal regulation of menstruation. Premature menopause. Menopause usually begins around age 50. But, for some women, the ovarian supply of eggs diminishes before age 40, and menstruation stops. Structural problems Problems with the sexual organs themselves also can cause amenorrhea. Examples include: Uterine scarring. Asherman’s syndrome, a condition in which scar tissue builds up in the lining of the uterus, can sometimes occur after a dilation and curettage (D&C), cesarean section or treatment for uterine fibroids. Uterine scarring prevents the normal buildup and shedding of the uterine lining. Lack of reproductive organs. Sometimes problems arise during fetal development that lead to a girl being born without some major part of her reproductive system, such as her uterus, cervix or vagina. Because her reproductive system didn’t develop normally, she can’t have menstrual cycles. Structural abnormality of the vagina. An obstruction of the vagina may prevent visible menstrual bleeding. A membrane or wall may be present in the vagina that blocks the outflow of blood from the uterus and cervix. risk factors elements which could growth your risk of amenorrhea might also include: family records. If other women in your family have experienced amenorrhea, you could have inherited a predisposition for the trouble. eating disorders. if you have an ingesting sickness, inclusive of anorexia or bulimia, you are at higher chance of developing amenorrhea. Athletic training. Rigorous athletic training can boom your threat of amenorrhea. headaches headaches of amenorrhea may additionally encompass: Infertility. in case you do not ovulate and feature menstrual intervals, you can’t end up pregnant. Osteoporosis. if your amenorrhea is resulting from low estrogen degrees, you could also be vulnerable to osteoporosis — a weakening of your bones.
