Knowledge | Amenorrhea in Women: Causes and Diagnosis
Amenorrhea is the absence of menstrual periods after puberty in someone who is not pregnant or menopausal. It is not simply an irregular cycle, but a complete absence of menstruation. Amenorrhea is not itself a disease, but it may be a symptom of an underlying health condition and should be discussed with a doctor.
1. Types of Amenorrhea
There are two types of amenorrhea:
Primary amenorrhea: No first menstrual period by age 15.
Secondary amenorrhea: Menstrual periods stop for 3 consecutive months or longer after previously regular cycles.
Symptoms of Amenorrhea
In addition to absent periods, symptoms may vary with the underlying cause and include:
Pelvic pain
Vision changes
Headache
Acne
Hair loss
Increased facial hair
Milky nipple discharge
No breast development (primary amenorrhea)
2. Causes of Amenorrhea
Causes vary depending on the type:
Possible causes of primary amenorrhea:
Reduced ovarian function
Problems involving the central nervous system or pituitary gland
Abnormalities of the reproductive organs
Common causes of secondary amenorrhea:
Pregnancy
Breastfeeding
Stopping birth control pills
Menopause
Certain contraceptive methods, such as injections or some intrauterine devices
Other causes include stress, poor nutrition, depression, extreme weight changes, polycystic ovary syndrome (PCOS), thyroid disease, and tumors.
3. Diagnosing Amenorrhea
Because amenorrhea has many possible causes, a doctor may use several tests to identify the cause. These may include:
Blood tests: Measure hormones such as follicle-stimulating hormone, thyroid-stimulating hormone, prolactin, and androgens.
Imaging: Ultrasound, CT, or magnetic resonance imaging (MRI) can help identify reproductive-organ abnormalities or tumors.
Hormone challenge test: Hormone medication is given to see whether it triggers menstrual bleeding and to assess possible estrogen deficiency.
Hysteroscopy: A hysteroscope is used to examine the inside of the uterus.
Genetic screening and chromosome testing: Used to detect genetic or chromosomal changes that may cause amenorrhea.
Treatment and Care
Treatment depends on the underlying cause. Hormone replacement therapy or birth control pills may restore menstrual cycles. Thyroid or pituitary disorders may be treated with medication, while structural abnormalities may require surgery. Managing stress, weight changes, or depression may also help restore menstruation when these factors affect the cycle.
Tracking cycle changes, symptoms, medications, and lifestyle changes can help a doctor identify the cause and develop an effective treatment plan.
