Amenorrhea is the lack of menstrual bleeding. Amenorrhea is a standard attribute in prepubertal, pregnant, and postmenopausal females. In females of reproductive age, diagnosing amenorrhea is an issue of first ascertaining whether pregnancy is the etiology. In the lack of pregnancy, the challenge would be to ascertain the precise reason for menses that are absent.

The area of the brain known as the hypothalamus regulates the menstrual cycle. The pituitary gland is stimulated by the hypothalamus. The pituitary gland lies just below the hypothalamus in the bottom of the brain.

Two hormones are released by the pituitary gland to help in regulating the female reproductive cycle. They have been luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

In order to get a woman to possess regular menstrual cycles, her hypothalamus, pituitary gland, ovaries and uterus should be working correctly. Vagina and her cervix should also possess a regular human body.

FSH and lH affect the creation of progesterone and estrogen. These hormones control cyclic changes. Including menstruation.

You can find just two kinds of amenorrhea:

Primary amenorrhea is the failure of menses to happen by age 16 years, in the existence of regular development and secondary sexual features. The beginning of puberty, including breast growth, is absent and also if 13 menses hasn't happened, a workup for primary amenorrhea should begin.

Secondary amenorrhea means the cessation of menses after menarche has happened. Oligomenorrhea is described as menses happening at periods longer than 35 days apart.

No consensus was achieved about the stage where oligomenorrhea becomes amenorrhea. Experts indicate the lack of menses for 6 months makes up amenorrhea, but the foundation for this particular recommendation is cloudy. To get a post-menarchal girl or a reproductive-old woman to see a menstrual cycle time of more than 90 days is uncommon. Practically speaking, this will be an indicator for an assessment to find the cause.

Secondary amenorrhea generally isn't harmless to your health. It may be medicated efficiently typically. Nonetheless, you should address the underlying conditions that cause amenorrhea to stop any complications.

What Can Cause Secondary Amenorrhea?

Throughout a standard menstrual cycle, estrogen levels increase. Estrogen is a hormone that is accountable for reproductive and sexual growth in women. The high estrogen levels cause the lining of the uterus, or womb, thicken and to grow. The uterus thickens, your body releases an egg into among the ovaries. It'll break apart when the egg is not fertilized by a man's sperm cell. This causes estrogen levels to fall. You will then spill additional blood and the thickened uterine lining through the vagina throughout your menstrual period.

But procedure may be interrupted by specific variables.

Hormonal Imbalances

A hormonal imbalance is the most typical reason for secondary amenorrhea. A hormonal imbalance can occur as an effect of:

- an overactive thyroid gland
- tumors on the pituitary gland
- high testosterone levels
- low estrogen levels

Hormonal birth control also can lead to secondary amenorrhea. Depo Provera, a birth control shot that is hormonal, and hormonal birth control pills may cause menstrual periods to be missed by you. Medicines and specific clinical treatments, including antipsychotic and chemotherapy drugs, may also activate amenorrhea.

Testosterone is the principal sex hormone in men. Nevertheless, in addition, it plays a role in development and the growth of reproductive tissues in women. High testosterone levels in a woman may result in absent or irregular menstrual periods.

Structural Problems

Scar tissue forming as a result of pelvic diseases or multiple dilation and curettage (D&C) processes can also prevent menstruation, and includes dilating the cervix and scraping the uterine lining with a spoon-shaped instrument called a curette. This surgical procedure is usually used to diagnose and treat abnormal uterine bleeding or to get rid of excessive tissue from your uterus.

Illnesses like polycystic ovary syndrome (PCOS) can cause hormonal imbalances which result in the development of ovarian cysts. Ovarian cysts are benign, or noncancerous, masses that grow in the ovaries. The hormonal imbalances that result from PCOS may also cause amenorrhea.

Factors Related to Lifestyle

Psychological pressure is just another potential cause of secondary amenorrhea. The body may react to extreme pressure by briefly interrupting your regular menstrual cycle. As soon as you work throughout your stress and nervousness your menstrual periods will probably restart.

Routine menstruation can be potentially affected by body weight too. Women that have become heavy or who have less than 15 percent body fat may discontinue getting menstrual periods. This really is particularly true for athletes who widely or excessively.

The Causes of Amenorrhea


Especially contraceptive drugs, specific drugs, can cause amenorrhoea in a wholesome woman. The possible lack of menstruation may take around per year to restart after discontinuing a medicine and generally starts soon after starting the drugs. Hormonal contraceptives which contain progestogen like the oral contraceptive Micronor, and particularly higher-dose formulas such as the injectable Depo Provera normally cause this side effect. Lengthy cycle use of combined hormonal contraceptives additionally enable suppression of menstruation. Patients who use and after that stop using contraceptives such as the combined oral contraceptive pill may experience secondary amenorrhoea as a withdrawal symptom. The link isn't well understood, as studies have found no difference in hormone levels between women who develop amenorrhoea as a withdrawal symptom after the cessation of OCOP use and women who experience secondary amenorrhoea due to other reasons. New contraceptive pills, like constant oral contraceptive pills (OCPs) which tend not to possess the regular 7 days of placebo pills in every single cycle, have been indicated to raise speeds of amenorrhoea in women. Studies reveal that women are likely to see amenorrhoea constant OCP use.

Antipsychotic drugs used to treat schizophrenia have always been recognized to cause amenorrhoea also. New research indicates that adding a dosage of Metformin to an antipsychotic drug regimen can restore menstruation. Metformin decreases resistance to the hormone insulin, together with amounts of prolactin, testosterone, and lutenizing hormone (LH). The LH/FSH ratio is also decreased by metformin. Results of the analysis on Metformin further implicate the management of the hormones as a primary reason for secondary amenorrhoea.

The usage of opiates (including diamorphine) on a regular basis has been proven to cause amenorrhoea in longer duration users.

Low body weight

Women who perform appreciable levels of exercise on a regular basis or lose a significant quantity of weight are in danger of growing hypothalamic (or 'fit') amenorrhoea. Functional Hypothalamic Amenorrhoea (FHA) might result from pressure, weight-loss, and excessive exercise. Many women who diet or who exercise in a higher degree don't take in enough calories to expend on their exercise together with to keep up their standard menstrual cycles. The threshold of growing amenorrhoea seems to be dependent on low energy availability in the place of complete weight because a vital minimum number of kept, readily marshalled energy is required to maintain regular menstrual cycles.

Secondary amenorrhea is brought on by low rates of the hormone leptin in females with low body weight. Like ghrelin, leptin signals energy balance and fat stores to the reproductive axis. Fell amounts of leptin are closely linked to low rates of body fat, and correlate using a slowing of GnRH pulsing.

Weight loss and energy imbalance can disrupt menstrual cycles through several mechanisms that are hormonal. Weight reduction may cause elevations in the hormone ghrelin which inhibits the hypothalamic-pituitary-ovarial axis. Raised concentrations of ghrelin change the amplitude of GnRH pulses, which causes diminished pituitary release of LH and follicle-stimulating hormone (FSH).

When a woman is experiencing an eating disorder, amenorrhoea, and osteoporosis jointly, this can be named female athlete triad syndrome. Too little eating causes amenorrhoea and bone loss leading and at times progressing to osteoporosis.

The societal aftereffects of amenorrhoea on an individual change significantly. Amenorrhoea is usually related to anorexia nervosa and other eating disorders, which have their particular effects. If secondary amenorrhoea is activated early in life, for example through weight loss or excessive exercise, menarche might not return later in life. A woman in this case could struggling to get pregnant, in spite of the aid of drugs. Long term amenorrhoea results in an estrogen deficiency which may bring about menopause for an early age. The hormone estrogen plays an important function in modulating calcium decrease after ages 25-30. When her ovaries no longer produce estrogen due to amenorrhoea, a woman is more inclined to endure accelerated calcium reduction, which then may lead to osteoporosis. Increased testosterone levels cause by amenorrhoea can result in body hair development and reduced breast size. Increased amounts of androgens, particularly testosterone, also can lead to ovarian cysts. Some research among runners that are amenorrhoeic suggests the lack of menses might come with a lack of self esteem.


It may also result from physical deformities. One case with this is Mayer-Rokitansky-Kuster-Hauser syndrome, the second-most common reason for primary amenorrhoea. The syndrome is defined by Mullerian agenesis. In MRKH Syndrome, the Mullerian ducts usually do not grow, which prevents menstruation. The syndrome usually develops during the first trimester of pregnancy. MRI techniques could be useful in discovering the degree of the difficulty. Other times primary amenorrhoea, which will be characteristic of the illness, may prevent pregnancy, although women may recuperate from MRKH syndrome.


Breastfeeding is a standard reason for secondary amenorrhoea, and frequently the illness lasts for over six months. Breastfeeding commonly lasts longer than lactational amenorrhoea, as well as the term of amenorrhoea changes depending how frequently a women breastfeeds. Lactational amenorrhoea was recommended as a way of family planning, particularly in developing countries where access to other ways of contraception could be restricted. Breastfeeding can be said to prevent more arrivals in the developing world than every other way of contraception or birth control. Lactational amenorrhoea is 98% percent successful as a way of preventing pregnancy in the very first six months postpartum.

How Long Does it Last?

In lots of adolescents with primary amenorrhea, puberty is not early. However there's no long-lasting issue.

How long secondary amenorrhea survives depends upon the reason.

For example:

- A woman who is no longer taking birth control pills may well not possess a period for three months to annually.

- cease a woman's menstrual periods until after childbirth.

- Mental or physical stress can cause amenorrhea for as long as the tension stays.

- Amenorrhea is long-term after menopause begins or after hysterectomy.

- Accelerated fat loss or gain, drugs and chronic illness may cause missed periods.


Your health professional will ask you about:

- Whether you're sexually active

- The date of your last menstrual period

- Your birth control processes

- Your eating habits

- Your pregnancy history

- Fast weight changes

- Your routines

- Obesity or extreme underweight

- The age when your mom entered menopause. (Many moms and daughters enter menopause at about the exact same age.)

- Your exercise regimen

- The quantity of the way it is dealt with by you, and anxiety that you experienced

- The kinds of drugs you're taking

Your medical history will be reviewed by your doctor. He/she will do a general physical examination, followed with a thorough pelvic exam. Your doctor will check whether you might be pregnant.

In case your doctor suspects a particular cause, he/she will ask additional questions. For instance, in case your doctor suspects a hormonal abnormality, he/she might ask about:

- Increased body hair

- Acne

- Extreme sensitivity to cold temperatures

- Uncommon breast secretions

- Constipation

- Dry skin

- Hair loss

If you're an athlete, your doctor will ask about your training course. That is very likely if you're underweight or possess a poor portion of body fat.

These tests might be carried out to recognize the root reason for your periods that were absent:

- Pelvic ultrasound. This painless test uses sound waves. It may identify structural issues in your uterus and ovaries.

- Blood and urine tests. These may discover imbalances of hormones that are female. It might result from issues with all the pituitary gland or ovaries. The issues are discovered, additional tests may be done. These can assess whether your levels of adrenal and thyroid hormones are standard.

- If bleeding doesn't happen, your doctor will order blood tests to check your FSH levels. FSH levels will help determine whether your issue is in hypothalamus or the ovaries.

- Progesterone challenge test. Your doctor may treat you with progesterone to see whether starts a menstrual period. You're most likely not releasing a mature egg at the center of your menstrual cycle if menstrual bleeding happens.

Added testing might be required to nail the reason for your periods that are missed. Diagnosing amenorrhea may be challenging. You will find lots of possible causes.

Which are the complications of amenorrhea?

Infertility is an important complication of amenorrhea for women who want to get pregnant. Osteopenia (a decrease in bone density) or osteoporosis is a complication of low estrogen levels, which might happen with prolonged amenorrhea. Other complications of amenorrhea depend upon the root reason for the amenorrhea.

What's the prognosis for a woman experiencing amenorrhea?

The prognosis for amenorrhea is dependent upon the origin of the amenorrhea and fluctuates widely. In the event the responsible variables could be corrected, hypothalamic amenorrhea that is clearly due to pressure, exercise, or weight loss usually could be corrected. The treatments may be of great advantage in preventing complications or unpleasant unwanted effects of amenorrhea in lots of women.

Can amenorrhea be avoided?

Amenorrhea is a symptom rather than a disease by itself. Therefore, amenorrhea could be avoided and then the extent the underlying cause could be avoided. For instance, amenorrhea that results from conditions that are inborn or genetic can't be avoided. On the other hand, amenorrhea that results from self imposed rigorous dieting or intensive exercise is usually not unpreventable.

What exactly is the treatment for amenorrhea?

Treatments change depending on the inherent state. If estrogen levels are low, crucial issues are difficulties of surgical correction if suitable and estrogen treatment. For all those who usually do not intend to possess biological children, treatment could not be necessary when the root reason for the amenorrhoea isn't threatening to their own health. Yet, in case of athletic amenorrhoea, lacks in leptin and estrogen regularly concurrently lead to bone loss, possibly resulting in osteoporosis.

The particular cause determines treatment of secondary and primary amenorrhea. Treatment targets could be create menstruation to alleviate symptoms of hormonal imbalance, prevent complications, or to attain fertility, although not all of those aims is possible in every instance.

Hypothalamic amenorrhea that's linked to excessive exercise, weight reduction, physical sickness, or mental pressure can generally be corrected by addressing the underlying cause. For instance, weight gain and decrease in strength of exercise can typically restore menstrual periods in women who've grown amenorrhea as a result of too intensive exercise who don't have added causes of amenorrhea or weight reduction. Sometimes, nutritional counselling might be of advantage.

In instances by which genetic or anatomical abnormalities will be the reason for amenorrhea (generally primary amenorrhea), surgery might be recommended.

In premature ovarian failure, hormone therapy might be advocated both to prevent the disagreeable symptoms of estrogen depletion together with prevent complications (see below) of low estrogen level like osteoporosis. This could contain oral contraceptive pills for all those women who don't want pregnancy or option estrogen and progesterone drugs. Younger women with premature ovarian failure may reap the benefits of this treatment to stop bone loss while postmenopausal hormone therapy was connected with specific health hazards in elderly women.

Dopamine agonist drugs including bromocriptine (Parlodel) can reduce elevated prolactin levels, which might cause amenorrhea. Thus, his or her doctor if proper may adjusts drug amounts.

Women with PCOS (polycystic ovary syndrome) may reap the benefits of treatments that reduce the amount or action of male hormones, or androgens.

Assisted reproductive technologies as well as the administration of gonadotropin medicines (drugs that stimulate follicle maturation in the ovaries) can be suitable for women with a few kinds of amenorrhea wishing to try to get pregnant.

While people and many businesses have promoted herbal treatments as a treatment for amenorrhea, not one of these have been proved to be of advantage. These treatments will not be governed by the U.S. FDA and the quality of herbal preparations isn't examined. Herbal treatments are linked with serious as well as lethal negative effects in infrequent instances, plus some preparations have already been proven to contain elevated quantities of toxins. It's advisable to find the help of your healthcare professional before determining to take a natural or substitute fix for amenorrhea.

Looking at Hypothalamic amenorrhoea, studies have supplied the administration of a selective serotonin reuptake inhibitor (SSRI) might correct abnormalities of Functional Hypothalamic Amenorrhoea (FHA) related to the problem of pressure-associated amenorrhoea. This includes the repair of the PI3K signaling pathway, which eases the integration of metabolic and neurological signals modulating gonadotropin releasing hormone (GnRH)/luteinizing hormone (LH). Quite simply, it modulates action and expression of neuropeptide systems that encourage GnRH release. Nevertheless, SSRI treatment represents a hormonal alternative that is potential to only one hormonal state of hypothalamic amenorrhoea. Also, as the state includes the internal workings of many neurotransmitters that are different, much research is still to be done on presenting hormonal treatment that might counteract the affects that are hormonal.

"Fit" amenorrhoea that is a part of the female athlete triad is treated by eating more and reducing the quantity and degree of exercise. If the underlying cause is the athlete triad then a multidisciplinary treatment including observation from a doctor, dietitian, and mental health counsel is preferred, along with support from family, buddies, and trainers. Although oral contraceptives can causes menses to return, oral contraceptives shouldn't function as the first treatment as they are able to hide the inherent trouble and enable other impacts of the eating disorder, like osteoporosis, continue to develop. Weight healing, or increased remainder doesn't constantly catalyze the return of a menses. Recommencement of ovulation implies a dependence on an entire network of hormones and neurotransmitters, changed in response to the original causes of secondary amenorrhoea. To treat drug-induced amenorrhoea, discontinuing the medicine on the suggestion of a doctor is a typical plan of action.

As for bodily treatments to hypothalamic amenorrhoea, injections of metreleptin (r-metHuLeptin) have been examined as treatment to estrogen deficiency caused by low gonadotropins as well as other neuroendocrine defects including low concentrations of thyroid and IGF1. R-metHuLeptin has seemed successful in restoring defects in the hypothalamic-pituitary-gonadal axis and enhancing reproductive, thyroid, and IGF hormones, along with bone formation, thereby healing infertility and the amenorrhoea. Yet, it hasn't proved successful in restoring of adrenocorticotropin and cortisol amounts, or bone resorption.


They are used traditionally, although many of the herbs listed below haven't been examined particularly for treatment of amenorrhea. Many act such as the hormone estrogen within the body. Speak with your doctor when you own a history or family history of cancers related to estrogen, including breast, cervical, uterine, and ovarian cancer.

Using herbs is a time honored approach to strengthening the body and treating disease. Herbs, however, can trigger unwanted effects and may communicate with other herbs, nutritional supplements, or medicines. Therefore, take herbs just under the supervision of a physician.

- Chaste tree: For high prolactin levels, chaste tree (Vitex agnus-castus) may help the pituitary gland function generally and could reduce prolactin levels, but nevertheless, it should be taken for 12 to 18 months. One very small study found that 10 of 15 women with amenorrhea began having periods after taking chaste tree for 6 months. Should you already use hormone therapy, usually do not use chaste tree except under your doctor's oversight. Chaste tree might interact using several medicines, including chlorpromazine (Thorazine), haloperidol (Haldol), levodopa, metoclopramide, olanzapine (Zyprexa), prochlorperazine (Compazine), quetiapine (Seroquel), ropinirole (Requip), and risperidone (Risperdal). It may make birth control pills less effective.

The following herbs have estrogen-like effects and so are from time to time used to take care of menopausal symptoms, although there are really no clinical trials that demonstrate whether or not they are safe or work:

- Lady's mantle (Alchemilla vulgaris) and vervain (Verbena officinalis): All these are other herbs which will help stimulate menstrual flow. Don't take these herbs without your doctor's oversight. In the event you take the mantle of lady your doctor should monitor your liver function.
- Black cohosh(Cimicifuga racemosa), licorice, (Glycyrrhiza glabra), and squaw vine (Mitchella repens): Black cohosh might interact using several drugs processed by the liver, including acetaminophen (Tylenol), atorvastatin (Lipitor), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), among others. Licorice socializes with many prescription and over the counter drugs, so ask your doctor before taking it. Don't take licorice in the event you have heart failure or high blood pressure.
- Wild yam: Some people believe wild yam is a very natural supply of progesterone, but that is false. The body cannot make progesterone, even though it was used to generate progesterone in the lab.
- Kelp (Laminaria hyperborea), oatstraw (Avena sativa), and horsetail (Equisetum arvense): These three are rich in minerals that will help boost thyroid function. Avoid horsetail for those who have diabetes, take lithium, or take a diuretic (water pill), like hydrochlorothiazide or furosemide (Lasix).

Don't take the herb blue cohosh (Caulophyllum thalictroides). This noxious herb must not be used without strict medical supervision.

Physical Medicine

The following help relieve pain from pelvic congestion and increase circulation:

- Compare sitz baths: Use two bowls that you could sit in. Sit in cold water for 1 minute, then in hot water for 3 minutes. Repeat this 3 times to finish one "set." Do 1 to 2 sets each week.
- Castor oil pack: Apply oil to some soft, clean cloth, spot on abdomen, and cover with plastic wrap. Put heating pad or a hot water bottle on the pack and let sit in your abdomen for 30 to 60 minutes. Though it could be advantageous to make use of for more, it is possible to safely make use of this treatment for 3 days. Speak with your healthcare provider to find out how long to put it to use.


Few studies have analyzed the effectiveness of specific homeopathic treatments. Professional homeopaths, however, may recommend treatments for amenorrhea depending on expertise. Before prescribing a remedy, homeopaths take into account an individualís constitutional type, which is your physical, mental, and intellectual make-up.

- Sepia:For women with irregular or late menstruation. They experience pain, toothaches, and frequent headaches when bearing down and may possess a sallow complexion. They might not feel hot and wish to be alone.
- Pulsatilla: For menstrual difficulties, particularly in women who've poor desire, nor favor exertion; they might pass out readily. They could be aggravated by heat and feel worse. They may want to take the open air.
- Graphites: For women with light or late menstruation. They could possess a sallow complexion and experience a sense of fullness or constipation and headaches. They frequently possess a fair complexion.


Acupuncturists give treatment to people with amenorrhea predicated on an individualized evaluation of the excesses and deficiencies of qi located in several meridians. Acupuncturists think that amenorrhea is frequently related to kidney and liver want, and treatment often concentrates on strengthening function in these types of places.

Acupuncture may enhance hormonal imbalances that could go together with amenorrhea and associated illnesses, including polycystic ovary syndrome (PCOS). A couple of small studies of women with fertility difficulties, which are occasionally associated with amenorrhea, imply that acupuncture might help boost ovulation.

When To Visit Your Doctor

You need to get in touch with your doctor if:

- You haven't had your first menstrual period and are 16

- You haven't began to grow breasts or pubic hair and are 14

In case you miss a period, if you're sexually active, call your doctor. You may have to really have a pregnancy test.

In the event you are not sexually active, see your doctor if:

- Your periods are unusual

- you've missed three consecutive menstrual periods

Oftentimes, teenaged girls can help stop primary amenorrhea. Practical exercise plan. Plus they ought to keep a weight that is normal.

Primary amenorrhea brought on by anatomic abnormalities can't be avoided.

It is possible to prevent some types of secondary amenorrhea. Take the next measures:

- Exercise moderately, but not excessively, to keep muscle tone and a perfect body weight.

- Eat a balanced diet which matches your recommended daily nutritional needs.

- Locate healthy outlets for psychological anxiety and clashes that are day-to-day.

- Prevent cigarette smoking and excessive alcohol consumption.

- Balance work, relaxation and rest.
