Treatments vary based on the underlying condition. Key issues are problems of surgical correction if appropriate and oestrogen therapy if oestrogen levels are low. For those who do not plan to have biological children, treatment may be unnecessary if the underlying cause of the amenorrhoea is not threatening to their health. However, in the case of athletic amenorrhoea, deficiencies in estrogen and leptin often simultaneously result in bone loss, potentially leading to osteoporosis.

"Athletic" amenorrhoea which is part of the female athlete triad is treated by eating more and decreasing the amount and intensity of exercise. If the underlying cause is the athlete triad then a multidisciplinary treatment including monitoring from a physician, dietitian, and mental health counselor is recommended, along with support from family, friends, and coaches. Although oral contraceptives can causes menses to return, oral contraceptives should not be the initial treatment as they can mask the underlying problem and allow other effects of the eating disorder, like osteoporosis, continue to develop. Weight recovery, or increased rest does not always catalyze the return of a menses. Recommencement of ovulation suggests a dependency on a whole network of neurotransmitters and hormones, altered in response to the initial triggers of secondary amenorrhoea. To treat drug-induced amenorrhoea, stopping the medication on the advice of a doctor is a usual course of action.

Looking at Hypothalamic amenorrhoea, studies have provided that the administration of a selective serotonin reuptake inhibitor (SSRI) might correct abnormalities of Functional Hypothalamic Amenorrhoea (FHA) related to the condition of stress-related amenorrhoea. This involves the repair of the PI3K signaling pathway, which facilitates the integration of metabolic and neural signals regulating gonadotropin releasing hormone (GnRH)/luteinizing hormone (LH). In other words, it regulates the neuronal activity and expression of neuropeptide systems that promote GnRH release. However, SSRI therapy represents a possible hormonal solution to just one hormonal condition of hypothalamic amenorrhoea. Furthermore, because the condition involves the inter workings of many different neurotransmitters, much research is still to be done on presenting hormonal treatment that would counteract the hormonal affects.

As for physiological treatments to hypothalamic amenorrhoea, injections of metreleptin (r-metHuLeptin) have been tested as treatment to oestrogen deficiency resulting from low gonadotropins and other neuroendocrine defects such as low concentrations of thyroid and IGF-1. R-metHuLeptin has appeared effective in restoring defects in the hypothalamic-pituitary-gonadal axis and improving reproductive, thyroid, and IGF hormones, as well as bone formation, thus curing the amenorrhoea and infertility. However, it has not proved effective in restoring of cortisol and adrenocorticotropin levels, or bone resorption.

Exercise amenorrhoea can be managed by eating a diet rich in calories and by decreasing the duration and intensity of exercise for at least 12 months. Amenorrhea usually persists and may take over 6 months to reverse .

Treatment is usually medication with dopamine agonists such as cabergoline, bromocriptine (often preferred when pregnancy is possible), and less frequently lisuride. A new drug in use is norprolac with the active ingredient quinagolide. Terguride is also used.

"Vitex agnus-castus" extract can be tried in cases of mild hyperprolactinaemia.

Certain medications, particularly contraceptive medications, can induce amenorrhoea in a healthy woman. The lack of menstruation usually begins shortly after beginning the medication and can take up to a year to resume after stopping a medication. Hormonal contraceptives that contain only progestogen like the oral contraceptive Micronor, and especially higher-dose formulations like the injectable Depo Provera commonly induce this side-effect. Extended cycle use of combined hormonal contraceptives also allow suppression of menstruation. Patients who use and then cease using contraceptives like the combined oral contraceptive pill may experience secondary amenorrhoea as a withdrawal symptom. The link is not well understood, as studies have found no difference in hormone levels between women who develop amenorrhoea as a withdrawal symptom following the cessation of OCOP use and women who experience secondary amenorrhoea because of other reasons. New contraceptive pills, like continuous oral contraceptive pills (OCPs) which do not have the normal 7 days of placebo pills in each cycle, have been shown to increase rates of amenorrhoea in women. Studies show that women are most likely to experience amenorrhoea after 1 year of treatment with continuous OCP use.

The use of opiates (such as heroin) on a regular basis has also been known to cause amenorrhoea in longer term users.

Anti-psychotic drugs used to treat schizophrenia have been known to cause amenorrhoea as well. New research suggests that adding a dosage of Metformin to an anti-psychotic drug regimen can restore menstruation. Metformin decreases resistance to the hormone insulin, as well as levels of prolactin, testosterone, and lutenizing hormone (LH). Metformin also decreases the LH/FSH ratio. Results of the study on Metformin further implicate the regulation of these hormones as a main cause of secondary amenorrhoea.

The aim for hormone replacement therapy (HRT) for both men and women is to ensure that the level of circulating hormones (testosterone for men and oestrogen/progesterone for women) is at the normal physiological level for the age of the patient. At first the treatment will produce most of the physical and psychological changes seen at puberty, with the major exception that there will be no testicular development in men and no ovulation in women.

After the optimum physical development has been reached HRT for men will continue to ensure that the normal androgen function is maintained; such as libido, muscle development, energy levels, hair growth, and sexual function. In women, a variety of types of HRT will either give a menstruation cycle or not as preferred by the patient. HRT is very important in both men and women to maintain bone density and to reduce the risk of early onset osteoporosis.

The fertility treatments used for both men and women would still include hormone replacement in their action.

There are a range of different preparations available for HRT for both men and women; a lot of these, especially those for women are the same used for standard HRT protocols used when hormone levels fall in later life or after the menopause.

For males with KS / CHH the types of delivery method available include daily patches, daily gel use, daily capsules, sub cutaneous or intramuscular injections or six monthly implants. Different formulations of testosterone are used to ensure both the anabolic and androgenic effects of testosterone are achieved.

Testosterone undecanoate is commonly used worldwide, though less so in the US, for treating male KS / CHH patients and has proved to be effective in maintaining good testosterone levels with an increased injection period of up to 12 weeks.

The precise treatment method used and interval between injections will vary from patient to patient and may need to be adjusted to maintain a physiological normal level of testosterone over a longer period of time to prevent the mood swings or adverse effects that can occur if testosterone levels are too high or low. Some treatments may work better with some patients than others so it might be a case of personal choice as which one to use.

As an alternative human chorionic gonadotrophin (hCG) can also be used to stimulate natural testosterone production. It acts in the same way as LH; stimulating the Leydig cells in the testes to produce testosterone. hCG can be used as pre-cursor to male fertility treatments but it can be used in isolation just for testosterone production.

There are no specialist HRT treatments available just for women with KS/HH but there are multitude of different HRT products on the market including oral contraceptives and standard post-menopause products. Pills are popular but patches are also available. It may take some trial and error to find the appropriate HRT for the patient depending on how her body reacts to the particular HRT. Specialist medical advice will be required to ensure the correct levels of oestrogen and progesterone are maintained each month, depending on whether the patient requires continuous HRT (no-bleed) or a withdrawal option to create a "menstrual" type bleed. This withdrawal bleed can be monthly or over longer time periods depending on the type of medication used.

Treatment for KS and other forms of HH can be divided into hormone replacement therapy and fertility treatments.

Males and females may be treated with hormone replacement therapy (i.e., with androgens and estrogens, respectively), which will result in normal sexual development and resolve most symptoms. In the case of 46,XY (genetically male) individuals who are phenotypically female and/or identify as the female gender, they should be treated with estrogens instead. Removal of the undescended testes should be performed in 46,XY females to prevent their malignant degeneration, whereas in 46,XY males surgical correction of the genitals is generally required, and, if necessary, an orchidopexy (relocation of the undescended testes to the scrotum) may be performed as well. Namely in genetic females presenting with ovarian cysts, GnRH analogues may be used to control high FSH and LH levels if they are unresponsive to estrogens.

Pseudocyesis is not known to have a direct underlying physical cause and there are no general recommendations regarding treatment with medications. In some cases, however, the patient may be given medications for such symptoms as the cessation of menstruation. When some patients with pseudocyesis have underlying psychological problems, they should be referred to a psychotherapist for the treatment of these problems. It is important at the same time, however, for the treating professional not to minimize the reality of the patient's physical symptoms. The treatment that has had the most success is demonstrating to the patient that she is not really pregnant by the use of ultrasound or other imaging techniques.

A number of treatments have become available to create a functioning vagina, yet in the absence of a uterus currently no surgery is available to make pregnancy possible. Standard approaches use vaginal dilators and/or surgery to develop a functioning vagina to allow for penetrative sexual intercourse. A number of surgical approaches have been used. In the McIndoe procedure, a skin graft is applied to form an artificial vagina. After the surgery, dilators are still necessary to prevent vaginal stenosis. The Vecchietti procedure has been shown to result in a vagina that is comparable to a normal vagina in patients. In the Vecchietti procedure, a small plastic “olive” is threaded against the vaginal area, and the threads are drawn through the vaginal skin, up through the abdomen and through the navel using laparoscopic surgery. There the threads are attached to a traction device. The operation takes about 45 minutes. The traction device is then tightened daily so the olive is pulled inwards and stretches the vagina by approximately 1 cm per day, creating a vagina approximately 7 cm deep in 7 days, although it can be more than this. Another approach is the use of an autotransplant of a resected sigmoid colon using laparoscopic surgery; results are reported to be very good with the transplant becoming a functional vagina.

Uterine transplantation has been performed in a number of people with MRKH, but the surgery is still in the experimental stage. Since ovaries are present, people with this condition can have genetic children through IVF with embryo transfer to a gestational carrier. Some also choose to adopt. In October 2014 it was reported that a month earlier a 36-year-old Swedish woman became the first person with a transplanted uterus to give birth to a healthy baby. She was born without a uterus, but had functioning ovaries. She and the father went through IVF to produce 11 embryos, which were then frozen. Doctors at the University of Gothenburg then performed the uterus transplant, the donor being a 61-year-old family friend. One of the frozen embryos was implanted a year after the transplant, and the baby boy was born prematurely at 31 weeks after the mother developed pre-eclampsia.

Promising research include the use of laboratory-grown structures, which are less subject to the complications of non-vaginal tissue, and may be grown using the person's own cells as a culture source. The recent development of engineered vaginas using the patient's own cells has resulted in fully functioning vaginas capable of menstruation and orgasm in a number of patients showing promise of fully correcting this condition in some of the sufferers.

Exercise induced amenorrhoea occurs in 5-25% of athletes and 1.8% of the general population. The incidence is higher in marathon runners and is more frequent in women who weigh less and were slightly younger . Exercise amenorrhoea has also been reported in ballet dancers, cyclists, swimmers and those involved in non-weight bearing sports .

Dysmenorrhea (or dysmenorrhoea), cramps or painful menstruation, involves menstrual periods that are accompanied by either sharp, intermittent pain or dull, aching pain, usually in the pelvis or lower abdomen.

It is generally treated surgically, with a hymenotomy or other surgery to remove any tissue that blocks the menstrual flow.

Prolactin secretion in the pituitary is normally suppressed by the brain chemical dopamine. Drugs that block the effects of dopamine at the pituitary or deplete dopamine stores in the brain may cause the pituitary to secrete prolactin. These drugs include the major tranquillizers (phenothiazines), trifluoperazine (Stelazine), and haloperidol (Haldol); antipsychotic medications, such as risperidone and quetiapine; metoclopramide (Reglan), domperidone, cisapride used to treat gastro-oesophageal reflux; medication-induced nausea (such as cancer drugs); and, less often, alpha-methyldopa and reserpine, used to control hypertension; and estrogens and TRH. The sleep drug ramelteon (Rozerem) also increases the risk of hyperprolactinaemia. A benzodiazepine analog, etizolam, can also increase the risk of hyperprolactinaemia. In particular, the dopamine antagonists metoclopramide and domperidone are both powerful prolactin stimulators and have been used to stimulate breast milk secretion for decades. However, since prolactin is antagonized by dopamine and the body depends on the two being in balance, the risk of prolactin stimulation is generally present with all drugs that deplete dopamine, either directly or as a rebound effect.

A menstrual disorder is an abnormal condition in a woman's menstrual cycle.

, there are no approved medications for the treatment of sarcopenia; however, β-hydroxy β-methylbutyrate (HMB), a metabolite of leucine which is sold as a dietary supplement, has demonstrated efficacy in preventing the loss of muscle mass in individuals with sarcopenia. A growing body of evidence supports the efficacy of HMB as a treatment for reducing, or even reversing, the loss of muscle mass, muscle function, and muscle strength in hypercatabolic disease states such as cancer cachexia; consequently, it is recommended that both the prevention and treatment of sarcopenia and muscle wasting in general include supplementation with HMB, regular resistance exercise, and consumption of a high-protein diet. Based upon a meta-analysis in 2015, HMB supplementation appears to be useful as a treatment for preserving lean muscle mass in older adults. More research is needed to determine the precise effects of HMB on muscle strength and function in this age group.

DHEA and human growth hormone have been shown to have little to no effect in this setting. Growth hormone increases muscle protein synthesis and increases muscle mass, but does not lead to gains in strength and function in most studies. This, and the similar lack of efficacy of its effector insulin-like growth factor 1 (IGF-1), may be due to local resistance to IGF-1 in aging muscle, resulting from inflammation and other age changes.

Testosterone or other anabolic steroids have also been investigated for treatment of sarcopenia, and seem to have some positive effects on muscle strength and mass, but cause several side effects and raise concerns of prostate cancer in men and virilization in women. Additionally, recent studies suggest testosterone treatments may induce adverse cardiovascular events. Other approved medications under investigation as possible treatments for sarcopenia include ghrelin, vitamin D, angiotensin converting enzyme inhibitors, and eicosapentaenoic acid.

As a chromosomal condition, there is no cure for Turner syndrome. However, much can be done to minimize the symptoms. For example:

- Growth hormone, either alone or with a low dose of androgen, will increase growth and probably final adult height. Growth hormone is approved by the U.S. Food and Drug Administration for treatment of Turner syndrome and is covered by many insurance plans. There is evidence that this is effective, even in toddlers.

- Estrogen replacement therapy such as the birth control pill, has been used since the condition was described in 1938 to promote development of secondary sexual characteristics. Estrogens are crucial for maintaining good bone integrity, cardiovascular health and tissue health. Women with Turner Syndrome who do not have spontaneous puberty and who are not treated with estrogen are at high risk for osteoporosis and heart conditions.

- Modern reproductive technologies have also been used to help women with Turner syndrome become pregnant if they desire. For example, a donor egg can be used to create an embryo, which is carried by the Turner syndrome woman.

- Uterine maturity is positively associated with years of estrogen use, history of spontaneous menarche, and negatively associated with the lack of current hormone replacement therapy.

Isolated 17,20-lyase deficiency (ILD), also called isolated 17,20-desmolase deficiency, is a rare endocrine and autosomal recessive genetic disorder which is characterized by a complete or partial loss of 17,20-lyase activity and, in turn, impaired production of the androgen and estrogen sex steroids. The condition manifests itself as pseudohermaphroditism (partially or fully underdeveloped genitalia) in males, in whom it is considered to be a form of intersex, and, in both sexes, as a reduced or absent puberty/lack of development of secondary sexual characteristics, resulting in a somewhat childlike appearance in adulthood (if left untreated).

Unlike the case of combined 17α-hydroxylase/17,20-lyase deficiency, isolated 17,20-lyase deficiency does not affect glucocorticoid production (or mineralocorticoid levels), and for that reason, does not result in adrenal hyperplasia or hypertension.

5α-Reductase is an enzyme that converts testosterone to 5α-dihydrotestosterone (DHT) in peripheral tissues. These enzymes also participate in the creation of such neurosteroids as allopregnanolone and THDOC, convert progesterone into dihydroprogesterone (DHP), and convert deoxycorticosterone (DOC) into dihydrodeoxycorticosterone (DHDOC). 5-ARD is biochemically characterized by low to low-normal levels of testosterone and decreased levels of DHT, creating a higher testosterone/DHT ratio.

DHT is a potent androgen, and is necessary for the development of male external genitalia in utero.

There are various explanations, none of which is universally accepted because of the complex involvement of cortical, hypothalamic, endocrine, and psychogenic factors. Proposed mechanisms include the effect of stress on the hypothalamo-pituitary-adrenal axis, constipation, weight gain, and the movement of intestinal gas.

However, diagnosis can be difficult due to the comprehensive measurements used in research that are not always practical in healthcare settings. Hand grip strength alone has also been advocated as a clinical marker of sarcopenia that is simple and cost effective and has good predictive power, although it does not provide comprehensive information.

Exercise remains the intervention of choice for sarcopenia but translation of findings into clinical practice is challenging. The type, duration and intensity of exercise are variable between studies, so an ‘off the shelf’ exercise prescription for sarcopenia remains an aspiration.

The role of nutrition in preventing and treating sarcopenia is less clear. Large, well-designed studies of nutrition particularly in combination with exercise are needed, ideally across healthcare settings. For now, basing nutritional guidance on the evidence available from the wider health context is probably the best approach with little contention in the goals of replacing vitamin D where deficient, and ensuring an adequate intake of calories and protein, although there is debate about whether currently recommended protein intake levels are optimal.

Treatment is typically achieved via diet and exercise, although metformin may be used to reduce insulin levels in some patients (typically where obesity is present). A referral to a dietician is beneficial. Another method used to lower excessively high insulin levels is cinnamon as was demonstrated when supplemented in clinical human trials.

A low carbohydrate diet is particularly effective in reducing hyperinsulinism.

A healthy diet that is low in simple sugars and processed carbohydrates, and high in fiber, and vegetable protein is often recommended. This includes replacing white bread with whole-grain bread, reducing intake of foods composed primarily of starch such as potatoes, and increasing intake of legumes and green vegetables, particularly soy.

Regular monitoring of weight, blood sugar, and insulin are advised, as hyperinsulinemia may develop into diabetes mellitus type 2.

It has been shown in many studies that physical exercise improves insulin sensitivity. The mechanism of exercise on improving insulin sensitivity is not well understood however it is thought that exercise causes the glucose receptor GLUT4 to translocate to the membrane. As more GLUT4 receptors are present on the membrane more glucose is taken up into cells decreasing blood glucose levels which then causes decreased insulin secretion and some alleviation of hyperinsulinemia. Another proposed mechanism of improved insulin sensitivity by exercise is through AMPK activity. The beneficial effect of exercise on hyperinsulinemia was shown in a study by Solomon et al. (2009), where they found that improving fitness through exercise significantly decreases blood insulin concentrations.

Treatments are focused on the underlying cause of hyponatremia and include

- fluid restriction

- 0.9% saline and hypertonic saline intravenously

- 100 ml of 3% saline hourly

When EAH is treated early, complete recovery is expected.

In addition to the above treatments, athletes experiencing EAH encephalopathy may also receive high-flow oxygen and a rapid infusion of 100 ml of 3% NaCl to reduce brain edema.

The condition affects only those with a Y-chromosome because dihydrotestosterone (DHT) has no known role in development of XX fetuses.

The usual treatments for overweight individuals is diet and physical exercise.

Dietitians generally recommend eating several balanced meals dispersed through the day, with a combination of progressive, primarily aerobic, physical exercise.

Because these general treatments help most case of obesity, they are common in all levels of overweight individuals.

As with any supplements and drugs, it is best to confer with a veterinarian as to the recommended dosages. Some drugs are not allowed in competition and may need to be withheld a few days before.

Adding potassium and salt to the diet may be beneficial to horses that suffer from recurrent bouts of ER. Horses in hard training may need a vitamin E supplement, as their requirements are higher than horses in more moderate work. The horse may also be deficient in selenium, and need a feed in supplement. Selenium can be dangerous if overfed, so it is best to have a blood test to confirm that the horse is in need of supplemental selenium.

Thyroid hormone supplementation is often beneficial for horses with low thyroid activity (only do so if the horse has been diagnosed with hypothyroidism).

Other drugs that have been used with success include phenytoin, dantrolene, and dimetyl glycine.

Bicarbonate and NSAIDs are of no use in preventing ER.
