Amenorrhea
Overview of Amenorrhea
Amenorrhea refers to the absence of menstrual periods during a woman's reproductive years. It can be classified into two types: primary and secondary. Primary amenorrhea occurs when a woman has never experienced menstrual periods, while secondary amenorrhea is the absence of periods in someone who had previously menstruated.
Primary amenorrhea can be caused by issues with the ovaries, reproductive organs, the pituitary gland, or the central nervous system. Secondary amenorrhea can be attributed to natural factors such as pregnancy or breastfeeding, or other factors like low body weight, stress, excessive physical activity, hormonal imbalances, and the use of birth control pills.
Diagnosing amenorrhea typically requires a series of tests, including pregnancy tests, thyroid function tests, ovary function assessments, male hormone tests, and prolactin tests. Treatment is based on the underlying cause of the condition. Hormone replacement therapy may be used if a hormonal imbalance is found. In cases where malnutrition is the cause, a proper diet plan can help resolve the issue. Surgery may be necessary to address any anatomical abnormalities causing amenorrhea.

Triggering Factors Of Amenorrhea
Amenorrhea is typically a symptom of an underlying health issue rather than a condition itself, and it can occur for various reasons. It may naturally occur during certain life stages such as pregnancy, breastfeeding, and menopause. However, its absence can also signal problems within the ovaries, uterus, hypothalamus, or pituitary gland, or may indicate an abnormality in the genital tract. Amenorrhea is also associated with infertility, some medications, and lifestyle factors.
Amenorrhea is categorized into two types: primary and secondary.
Primary Amenorrhea (failure to menstruate by age 16)
This can be caused by several factors:
- Genetic disorders: In some cases, genetic abnormalities can prevent the ovaries from functioning properly. Turner’s syndrome, where there is a missing X chromosome, can result in ovarian insufficiency and delayed or absent menstruation due to defects in genital development.
- Another genetic cause is Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome, where the mullerian ducts (which develop into the female reproductive system) fail to form normally, resulting in the absence of the uterus and cervix. Though individuals with MRKH have normal ovaries and secondary sexual characteristics, they experience primary amenorrhea because they lack a functioning uterus.
- Issues with the hypothalamus or pituitary gland: Hormonal disruptions due to problems with these glands can lead to amenorrhea or delay the start of menstruation.
- Imperforate hymen: This condition occurs when the hymen lacks an opening and fully blocks the vagina.
- Transverse vaginal septum: A birth defect where a tissue wall forms across the vagina, obstructing part or all of it.
- Constitutional delay of puberty: This temporary condition is characterized by a prolonged childhood phase and delayed puberty. It is not caused by a disease but reflects a variation in the normal timing of puberty. While more common in boys, girls may experience secondary sexual characteristics and menarche after age 14 and 16, respectively. Genetic or family factors may contribute to this delay, and this diagnosis is made after ruling out other causes.
Secondary Amenorrhea (absence of periods for at least six months after regular menstruation)
This type can result from various causes, including:
Natural causes: Pregnancy is the most common natural cause of secondary amenorrhea. Other physiological causes include breastfeeding and menopause.
Lactational amenorrhea is caused by high prolactin levels and low luteinizing hormone (LH), which suppress ovarian function. The duration of this condition depends on the frequency of breastfeeding.
Health conditions: Several conditions can lead to secondary amenorrhea, such as:
- Pituitary tumors: Noncancerous tumors in the pituitary gland can disrupt the hormonal regulation of menstruation.
- Thyroid disorders: The thyroid gland regulates metabolism and is crucial for puberty and menstruation. Both overactive and underactive thyroid function can result in menstrual irregularities, including amenorrhea.
- Polycystic ovary syndrome (PCOS): A hormonal disorder common in women of reproductive age, PCOS can cause irregular periods, excess body and facial hair, ovarian cysts, and infertility. Many women with PCOS experience either amenorrhea or oligomenorrhea (irregular periods).
- Hypothalamic amenorrhea: This condition occurs when the hypothalamus stops producing gonadotropin-releasing hormone (GnRH), which is essential for initiating the menstrual cycle.
- Low body weight: Excessive exercise or significant weight loss can lead to Functional Hypothalamic Amenorrhea (FHA), as insufficient calorie intake disrupts normal menstrual cycles.
- Hyperandrogenism: High levels of male hormones can impact the female reproductive system, caused by ovarian or adrenal tumors or certain congenital conditions.
- Premature menopause: Occurring before age 40, premature menopause results from the early depletion of ovarian eggs, leading to the cessation of menstruation.
Medications and therapies: These can include:
- Birth control pills: Some contraceptive pills may result in missed or absent periods. Injectables and hormonal IUDs can also cause amenorrhea. It may take a few months for a normal menstrual cycle to resume after discontinuing these methods.
- Recreational drugs: Long-term use of opiates (such as heroin) has been linked to amenorrhea.
- Antipsychotic drugs: These medications, used to treat conditions like schizophrenia, can lead to hormonal imbalances that result in amenorrhea.
- Radiation and chemotherapy: Cancer treatments such as radiation therapy and chemotherapy can damage estrogen-producing cells in the ovaries, leading to amenorrhea.
Poor nutrition: Deficiencies in essential nutrients can affect the hypothalamus and pituitary gland, disrupting menstruation.
Stress: Stress can alter hormone levels and lead to hypothalamic amenorrhea.
Potential Risks for Amenorrhea
Several factors can increase the likelihood of developing amenorrhea. Some of the key risk factors include:
Eating Disorders
- Eating disorders are psychological conditions that lead to unhealthy eating behaviors. These often begin with an obsession over food, body weight, or body shape. Anorexia nervosa is one of the most recognized eating disorders, where individuals see themselves as overweight, despite being dangerously underweight.
- Bulimia nervosa is another disorder, where individuals consume large amounts of food in a short period of time. These disorders are more common in women, particularly during adolescence and early adulthood. When present, the most frequent cause of missed periods is hypothalamic amenorrhea (HA).
Excessive Exercise
- Engaging in excessive physical activity can lead to less frequent hormone release or a reduction in the amount of hormone released with each pulse. The risk of amenorrhea is higher when excessive exercise is paired with a low-calorie diet or a low body fat percentage.
Family History
- If there is a history of delayed or irregular menstruation within the family, there may be a genetic tendency to develop amenorrhea.
Structural Abnormalities
- Girls with congenital conditions that result in underdeveloped genital or pelvic organs may be at risk of developing amenorrhea.
Tumors and Their Treatments
- After undergoing chemotherapy or radiation therapy, ovarian failure may occur, which can lead to the cessation of menstruation.
Diagnosis Of Amenorrhea
Physical Examination and Medical History
During the initial examination, the physician will ask about the patient’s age and the onset of menstruation (menarche) to help determine whether the amenorrhea is primary or secondary. If the individual has never menstruated, it is considered primary amenorrhea. Any other cases would be classified as secondary amenorrhea.
The doctor will inquire about symptoms such as night sweats, sleep disturbances, and hot flashes, which may suggest premature ovarian failure. A history of chemotherapy or radiation therapy should also be explored, as these treatments can cause ovarian failure, particularly in younger women.
The physician will also check for chronic illnesses that could impact the hypothalamic-pituitary axis, which is critical for regulating the menstrual cycle.
The physical examination will include:
- Assessing body mass index (BMI) to rule out eating disorders like anorexia nervosa or malnutrition.
- Measuring the patient’s height, weight, and fat index to identify possible chronic health issues.
- Examining the breasts, pubic hair, and clitoral index to check for genetic syndromes, such as Turner's syndrome, which may be ruled out with a normal chest examination.
Laboratory Tests
Several blood tests may be necessary, including:
- Beta human chorionic gonadotropin (Beta-hCG): This test helps confirm or rule out pregnancy, the most common cause of amenorrhea, as the hCG hormone is produced by the embryo and can be detected in the blood after a missed period.
- Ovary Function Tests: These tests measure follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels. The FSH test helps diagnose issues with sexual development, menstruation, and fertility, while the LH test monitors the regulation of the menstrual cycle and sexual development. Low levels of FSH suggest a malfunctioning ovary.
- Thyroid Function Tests: High levels of thyroid-stimulating hormone (TSH) with normal levels of other thyroid hormones usually indicate hypothyroidism, which can cause amenorrhea. Thyroid hormones are crucial for metabolism and influence puberty and menstruation.
- Prolactin Test: Elevated prolactin levels are often associated with amenorrhea. This hormone plays a key role in reproductive functions and is commonly elevated in conditions that disrupt the menstrual cycle, such as hyperprolactinemia, which can lead to secondary amenorrhea or oligomenorrhea.
- Progesterone Challenge Test: Also known as the progestin challenge test, this helps differentiate between causes like anovulation, anatomical issues, or estrogen deficiency. If bleeding occurs within 2 to 7 days after progesterone withdrawal, the cause is likely anovulation. If no bleeding occurs, the cause may be related to premature ovarian failure or other factors.
Imaging Tests
Depending on the symptoms, various imaging tests may be recommended:
- Ultrasound: This imaging test uses sound waves to produce detailed images of the internal organs. If a person has never menstruated, the doctor may suggest an ultrasound to check for abnormalities in the reproductive organs. If the uterus is absent, karyotype analysis may be performed to evaluate for conditions like Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.
- Magnetic Resonance Imaging (MRI): MRI uses powerful magnetic fields and radio waves to create detailed images of the organs and tissues. An MRI may be ordered to check for a pituitary tumor, which can cause amenorrhea by compressing the pituitary gland and interfering with its hormone production.
Hysteroscopy
If the cause of amenorrhea is not identified through other tests, a hysteroscopy may be conducted. This procedure uses a thin, lighted tube (hysteroscope) to examine the inside of the cervix and uterus. It helps diagnose conditions like abnormal vaginal bleeding, polyps, or fibroids that could be affecting menstruation.
Karyotyping
In cases where a family history or genetic syndrome is suspected, a karyotype (chromosomal analysis) may be performed. Although it is not a routine test for amenorrhea, it can be helpful for diagnosing chromosomal abnormalities, such as Turner syndrome, which can cause primary amenorrhea in girls who have not started menstruating by ages 11 to 15.
Preventive Measures Of Amenorrhea
To reduce the risk of developing amenorrhea, women can follow certain health practices:
- Maintain a healthy weight
- Engage in regular physical activity
- Follow a nutritious and balanced diet
- Manage stress levels effectively
- Ensure adequate and consistent sleep
- Be mindful of your menstrual cycle, so you can notice any missed periods
Specialists to Consult
In some cases, identifying the underlying cause of amenorrhea can be challenging. If a woman misses three consecutive periods without being pregnant and suspects a reproductive or hormonal issue, it is advisable to consult with:
- Gynecologist: A gynecologist specializes in women's reproductive health and can diagnose and treat conditions related to the uterus, ovaries, fallopian tubes, and breasts.
- Endocrinologist: An endocrinologist focuses on the endocrine system and the hormones produced by various glands, which could be involved in the regulation of menstruation.
Treatment Of Amenorrhea
The treatment for amenorrhea primarily depends on the underlying cause and the individual's overall health:
Medications
- If amenorrhea is caused by estrogen deficiency, estrogen replacement therapy may be prescribed.
- Dopamine Agonists: Drugs like bromocriptine and cabergoline are used to treat hyperprolactinemia (elevated prolactin levels), helping to restore normal endocrine function and stimulate ovulation.
- For women with Polycystic Ovary Syndrome (PCOS), metformin may be recommended to promote ovulation.
- Hormonal Medications: Birth control pills or other hormonal treatments, including oral contraceptives, may be used to regulate the menstrual cycle and provide estrogen replacement. Before starting oral contraceptives, withdrawal bleeding is typically induced with an injection of progesterone or the oral administration of 5-10 mg of medroxyprogesterone for 10 days.
- Estrogen Replacement Therapy (ERT): This is helpful for balancing hormones and restarting the menstrual cycle in women with primary ovarian insufficiency (POI). ERT replaces the estrogen no longer produced by the ovaries.
- Thyroid Treatments: Hypothyroidism can be treated with levothyroxine, while hyperthyroidism can be managed with antithyroid medications such as methimazole.
Surgical Treatments
- Pituitary Tumors: If a pituitary tumor is present, medications may be used to shrink it. If these medications are ineffective, surgery may be needed to remove the tumor, often through the nose and sinuses. In some cases, radiation therapy may also be used to shrink the tumor.
- Intrauterine Adhesions: Women with scar tissue inside the uterus may require a procedure known as hysteroscopic resection to remove the adhesions and restore normal menstruation.
Health Complications Of Amenorrhea
Amenorrhea can lead to a variety of additional health issues, including:
- Infertility: One significant consequence of amenorrhea is difficulty in conceiving. Whether it's primary or secondary amenorrhea lasting for several months, it could indicate an underlying disease or condition that may result in infertility. Hormonal imbalances that cause amenorrhea can also increase the risk of miscarriage or other pregnancy complications.
- Psychological Stress: Experiencing irregular or absent periods, especially when others around you are menstruating, can be emotionally challenging. This is particularly true for women trying to conceive and start a family.
- Osteoporosis: Estrogen plays a vital role in maintaining bone health. When amenorrhea is caused by low estrogen levels or issues with estrogen production, women may be at higher risk for developing weak or brittle bones, increasing the likelihood of osteoporosis.
- Pelvic Pain: Structural problems that contribute to amenorrhea may also lead to discomfort or pain in the pelvic region.
Alternative Therapies For Amenorrhea
Yoga and Exercise
Engaging in yoga and physical activity at least three times a week can enhance blood circulation, increase energy levels, and reduce feelings of fatigue. These practices are effective in alleviating stress, anxiety, and pain, while also helping the body remain balanced and energized.
Acupuncture
Acupuncture, a technique from traditional Chinese medicine, involves the insertion of thin needles into specific points on the body. This treatment is believed to help correct hormonal imbalances associated with amenorrhea. It is also thought to stimulate nerves and muscles, promoting the release of natural pain-relieving hormones.
Massage
Massage therapy can improve blood flow and help relieve pain caused by pelvic congestion. While massage addresses physical discomfort, it does not target the underlying causes of amenorrhea but provides relief from symptoms such as pain.
Nutritional Approach
Adopting a balanced diet, with a focus on healthy fats (unsaturated fats), grains, vegetables, and omega-3 fatty acids, can support overall health and prevent the development of amenorrhea. Diets low in fat may increase the risk of this condition. Supplementing with calcium, Vitamin D3, magnesium, and Vitamin K is beneficial for women with irregular periods, as they are more prone to bone weakness (osteoporosis). Vitamin B6 (pyridoxine) can help regulate prolactin levels, a hormone often elevated in women with amenorrhea.
Chiropractic Care
Chiropractic care, which focuses on the neuromusculoskeletal system (bones, muscles, nerves, tendons, and ligaments), can naturally alleviate menstrual symptoms and promote fertility. This approach aims to reduce pain and enhance overall bodily function.
Hot Water Bath
Taking a hot water bath can soothe discomfort caused by missed periods. The heat has muscle-relaxing properties, improving blood circulation and reducing muscle tension, offering relief from physical symptoms associated with amenorrhea
Homemade Remedies for Amenorrhea
Certain herbs are believed to have estrogen-like effects and are sometimes used to alleviate symptoms of amenorrhea. In addition to conventional treatments, some home remedies may offer relief from amenorrhea symptoms, including:
- Fenugreek (Methi): Known for addressing various menstrual and reproductive issues, fenugreek has shown positive results in promoting milk production, easing amenorrhea, and relieving menstrual cramps.
- Saffron (Kesar): This antioxidant herb helps flush out toxins and reduce stress. Its therapeutic effects are attributed to its ability to relax smooth muscles and stimulate menstruation.
- Chamomile (Babunah ke phul): Chamomile is often used for its relaxing and antispasmodic properties. It can be taken as a supplement or consumed as tea, particularly helpful for stress-induced amenorrhea.
- Turmeric (Haldi): With its ancient medicinal properties, turmeric is often used to heal internal injuries and act as a uterine stimulant, helping to regulate menstrual flow.
- Lemon Balm (Nimbu Balm): This herb is commonly used to treat menstrual issues, including amenorrhea, and can help promote the menstrual cycle and reduce menstrual cramps.
- Blue Cohosh: Known for its phytoestrogenic properties, blue and black cohosh are frequently used to alleviate menopause symptoms. The phytochemical opsonin, found in blue cohosh, stimulates blood flow to the pelvic region, effectively addressing amenorrhea and other gynecological concerns.
