Diagnosis of cortisone reductase deficiency is done through analysis of cortisol to cortisone metabolite levels in blood samples. As of now, there is no treatment for cortisone reductase deficiency. Shots of cortisol are quickly metabolised into cortisone by the dysregulated 11β-HSD1 enzyme; however, symptoms can be treated. Treatment of hyperandroginism can be done through prescription of antiandrogens. They do so by inhibiting the release of gonadotropin and luteinizing hormone, both hormones in the pituitary, responsible for the production of testosterone.

The goal of newborn screening programs is to detect and start treatment within the first 1–2 weeks of life. Treatment consists of a daily dose of thyroxine, available as a small tablet. The generic name is levothyroxine, and several brands are available. The tablet is crushed and given to the baby with a small amount of water or milk. The most commonly recommended dose range is 10-15 μg/kg daily, typically 12.5 to 37.5 or 44 μg.

Within a few weeks, the T and TSH levels are rechecked to confirm that they are being normalized by treatment. As the child grows up, these levels are checked regularly to maintain the right dose. The dose increases as the child grows.

The most common method to manage hypoglycemia and diabetes is with an insulin pump. . However in infants and very young children long acting insulins like Glargine and Levemir are preferred to prevent recurrent hypoglycemia . As soon as parent knows Walcott-Rallison syndrome is the source, treatment or therapy plans need to be drawn up along with frequent check ins to make sure kidney and liver functions are around normal and insulin therapy are working. If needed, the patient can undergo thyroxin therapy in order to maintain proper thyroid stimulating hormone levels. This has only been needed in a few cases were hypothyroidism was present in the patient.

Adding liothyronine (synthetic T) to levothyroxine has been suggested as a measure to provide better symptom control, but this has not been confirmed by studies. In 2007, the British Thyroid Association stated that combined T and T therapy carried a higher rate of side effects and no benefit over T alone. Similarly, American guidelines discourage combination therapy due to a lack of evidence, although they acknowledge that some people feel better when receiving combination treatment. Treatment with liothyronine alone has not received enough study to make a recommendation as to its use; due to its shorter half-life it needs to be taken more often.

People with hypothyroidism who do not feel well despite optimal levothyroxine dosing may request adjunctive treatment with liothyronine. A 2012 guideline from the European Thyroid Association recommends that support should be offered with regards to the chronic nature of the disease and that other causes of the symptoms should be excluded. Addition of liothyronine should be regarded as experimental, initially only for a trial period of 3 months, and in a set ratio to the current dose of levothyroxine. The guideline explicitly aims to enhance the safety of this approach and to counter its indiscriminate use.

Myxedema coma or severe decompensated hypothyroidism usually requires admission to the intensive care, close observation and treatment of abnormalities in breathing, temperature control, blood pressure, and sodium levels. Mechanical ventilation may be required, as well as fluid replacement, vasopressor agents, careful rewarming, and corticosteroids (for possible adrenal insufficiency which can occur together with hypothyroidism). Careful correction of low sodium levels may be achieved with hypertonic saline solutions or vasopressin receptor antagonists. For rapid treatment of the hypothyroidism, levothyroxine or liothyronine may be administered intravenously, particularly if the level of consciousness is too low to be able to safely swallow medication. While administration through a nasogastric tube is possible, this may be unsafe and is discouraged.

Life long hormone replacement therapy for the hormones that are missing.

Ideally a woman who is known to have hyperthyroidism should seek pre-pregnancy advice, although as yet there is no evidence for its benefit. Appropriate education should allay fears that are commonly present in these women. She should be referred for specialist care for frequent checking of her thyroid status, thyroid antibody evaluation and close monitoring of her medication needs. Medical therapy with anti-thyroid medications is the treatment of choice for hyperthyroidism in pregnancy.Methimazole and propylthiouracil (PTU) are effective in preventing pregnancy complications by hyperthyroidism. Surgery is considered for patients who suffer severe adverse reactions to anti-thyroid drugs and this is best performed in the second trimester of pregnancy. Radioactive iodine is absolutely contraindicated in pregnancy and the puerperium. If a woman is already receiving carbimazole, a change to propylthiouracil (PTU) is recommended but this should be changed back to carbimazole after the first trimester. This is because carbimazole can rarely be associated with skin and also mid line defects in the fetus but PTU long term also can cause liver side effects in the adult. Carbimazole and PTU are both secreted in breast milk but evidence suggests that antithyroid drugs are safe during lactation. There are no adverse effects on IQ or psychomotor development in children whose mothers have received antithyroid drugs in pregnancy.

Current guidelines suggest that a pregnant patient should be on PTU during the first trimester of pregnancy due to lower tetragenic effect and then be switched to methimazole during the second and third trimester due to lower liver dysfunction side effects.

Treatment modality depends on the cause. Tumors may be removed surgically, but pituitary stalk interruption may persist. Usually, replacement of those hormones that are reduced due to failed feedback control systems will be necessary.

The disorder is treated with vasopressin analogs such as Desmopressin. Nonetheless, many times desmopressin alone is not enough to bring under control all the symptoms, and another intervention must be implemented.

Direct treatment is geared toward resolving hyperprolactinemic symptoms or reducing tumor size. Patients on medications that cause hyperprolactinaemia should have them withdrawn if possible. Patients with hypothyroidism should be given thyroid hormone replacement therapy. When symptoms are present, medical therapy is the treatment of choice. Patients with hyperprolactinemia and no symptoms (idiopathic or microprolactinoma) can be monitored without treatment. Consider treatment for women with amenorrhea. In addition, dual energy X-ray absorptiometry scanning should be considered to evaluate bone density. The persistent hypogonadism associated with hyperprolactinemia can lead to osteoporosis. Treatment significantly improves the patient's quality of life. If the goal is to treat hypogonadism only, patients with idiopathic hyperprolactinemia or microadenoma can be treated with estrogen replacement therapy and prolactin levels can be monitored. Radiation treatment is another option. However, the risk of hypopituitarism makes this a poor choice. It may be necessary for rapidly growing tumors, but its benefits in routine treatment have not been shown to outweigh the risks.

Many of the common symptoms of hyperthyroidism such as palpitations, trembling, and anxiety are mediated by increases in beta-adrenergic receptors on cell surfaces. Beta blockers, typically used to treat high blood pressure, are a class of drugs that offset this effect, reducing rapid pulse associated with the sensation of palpitations, and decreasing tremor and anxiety. Thus, a patient suffering from hyperthyroidism can often obtain immediate temporary relief until the hyperthyroidism can be characterized with the Radioiodine test noted above and more permanent treatment take place. Note that these drugs do not treat hyperthyroidism or any of its long-term effects if left untreated, but, rather, they treat or reduce only symptoms of the condition.

Some minimal effect on thyroid hormone production however also comes with Propranolol - which has two roles in the treatment of hyperthyroidism, determined by the different isomers of propranolol. L-propranolol causes beta-blockade, thus treating the symptoms associated with hyperthyroidism such as tremor, palpitations, anxiety, and heat intolerance. D-propranolol inhibits thyroxine deiodinase, thereby blocking the conversion of T to T, providing some though minimal therapeutic effect. Other beta-blockers are used to treat only the symptoms associated with hyperthyroidism. Propranolol in the UK, and metoprolol in the US, are most frequently used to augment treatment for hyperthyroid patients.

There are no treatments which increase prolactin levels in humans. Treatment differs based on the reason for diagnosis. Women who are diagnosed with hypoprolactinemia following lactation failure are typically advised to formula feed, although treatment with metoclopramide has been shown to increase milk supply in clinical studies. For subfertility, treatment may include clomiphene citrate or gonadotropins.

General indications for pituitary surgery include patient drug intolerance, tumors resistant to medical therapy, patients who have persistent visual field defects in spite of medical treatment, and patients with large cystic or hemorrhagic tumors.

Levothyroxine is a stereoisomer of thyroxine (T4) which is degraded much more slowly and can be administered once daily in patients with hypothyroidism. Natural thyroid hormone from pigs is sometimes also used, especially for people who cannot tolerate the synthetic version. Hyperthyroidism caused by Graves' disease may be treated with the thioamide drugs propylthiouracil, carbimazole or methimazole, or rarely with Lugol's solution. Additionally, hyperthyroidism and thyroid tumors may be treated with radioactive iodine. Ethanol injections for the treatment of recurrent thyroid cysts and metastatic thyroid cancer in lymph nodes can also be an alternative to surgery.

Surgery (thyroidectomy to remove the whole thyroid or a part of it) is not extensively used because most common forms of hyperthyroidism are quite effectively treated by the radioactive iodine method, and because there is a risk of also removing the parathyroid glands, and of cutting the recurrent laryngeal nerve, making swallowing difficult, and even simply generalized staphylococcal infection as with any major surgery. Some people with Graves' may opt for surgical intervention. This includes those that cannot tolerate medicines for one reason or another, people that are allergic to iodine, or people that refuse radioiodine.

If people have toxic nodules treatments typically include either removal or injection of the nodule with alcohol.

Thyroid surgery is performed for a variety of reasons. A nodule or lobe of the thyroid is sometimes removed for biopsy or because of the presence of an autonomously functioning adenoma causing hyperthyroidism. A large majority of the thyroid may be removed ("subtotal thyroidectomy)" to treat the hyperthyroidism of Graves' disease, or to remove a goiter that is unsightly or impinges on vital structures.

A complete thyroidectomy of the entire thyroid, including associated lymph nodes, is the preferred treatment for thyroid cancer. Removal of the bulk of the thyroid gland usually produces hypothyroidism unless the person takes thyroid hormone replacement. Consequently, individuals who have undergone a total thyroidectomy are typically placed on thyroid hormone replacement (e.g. Levothyroxine) for the remainder of their lives. Higher than normal doses are often administered to prevent recurrence.

If the thyroid gland must be removed surgically, care must be taken to avoid damage to adjacent structures, the parathyroid glands and the recurrent laryngeal nerve. Both are susceptible to accidental removal and/or injury during thyroid surgery.

The parathyroid glands produce parathyroid hormone (PTH), a hormone needed to maintain adequate amounts of calcium in the blood. Removal results in hypoparathyroidism and a need for supplemental calcium and vitamin D each day. In the event that the blood supply to any one of the parathyroid glands is endangered through surgery, the parathyroid gland(s) involved may be re-implanted in surrounding muscle tissue.

The recurrent laryngeal nerves provide motor control for all external muscles of the larynx except for the cricothyroid muscle, which also runs along the posterior thyroid. Accidental laceration of either of the two or both recurrent laryngeal nerves may cause paralysis of the vocal cords and their associated muscles, changing the voice quality.

People affected by adipsia lack the ability to feel thirst, thus they often must be directed to drink. Adipsic persons may undergo training to learn when it is necessary that they drink water. Currently, there is no medicine available to treat adipsia. For people with adipsia because of hypothalamic damage, there is no surgical or medicinal option to fix the damage. In some cases where adipsia was caused by growths on thirst centers in the brain, surgical removal of the growths was successful in treating adipsia. Although adipsic persons must maintain a strict water intake schedule, their diets and participation in physical activities are not limited.

People affected by diabetes insipidus have the option of using the intranasal or oral hormone desmopressin acetate (DDAVP), which is molecularly similar enough to vasopressin to perform its function. In this case, desmopressin helps the kidneys to promote reabsorption of water. Some doctors have reported success in treating psychogenic adipsic patients with electroconvulsive therapy, although the results are mixed and the reason for its success is still unknown. Additionally, some patients who do not successfully complete behavioral therapy may require a nasogastric tube in order to maintain healthy levels of fluids.

Because most patients respond to steroids or immunosuppressant treatment, this condition is now also referred to as steroid-responsive encephalopathy.

Initial treatment is usually with oral prednisone (50–150 mg/day) or high-dose IV methylprednisolone (1 g/day) for 3–7 days. Thyroid hormone treatment is also included if required.

Failure of some patients to respond to this first line treatment has produced a variety of alternative treatments including azathioprine, cyclophosphamide, chloroquine, methotrexate, periodic intravenous immunoglobulin and plasma exchange. There have been no controlled trials so the optimal treatment is not known.

Seizures, if present, are controlled with typical antiepileptic agents.

Most children born with congenital hypothyroidism and correctly treated with thyroxine grow and develop normally in all respects. Even most of those with athyreosis and undetectable T levels at birth develop with normal intelligence, although as a population academic performance tends to be below that of siblings and mild learning problems occur in some.

Congenital hypothyroidism is the most common preventable cause of intellectual disability. Few treatments in the practice of medicine provide as large a benefit for as small an effort.

The developmental quotient (DQ, as per Gesell Developmental Schedules) of children with hypothyroidism at age 24 months that have received treatment within the first 3 weeks of birth is summarised below:

For most women, the hyperthyroid phase presents with very mild symptoms or is asypmtomatic; intervention is usually not required. If symptomatic cases require treatment, a short course of beta-blockers would be effective.

Assessing treatment for the hypothyroid is more complex. Women with symptoms or a very high TSH level, or both, are usually prescribed a course of levothyroxine. Asymptomatic women with slightly elevated TSH levels who are planning subsequent pregnancies, should consider a course of treatment until completion of the family to avoid possible developmental complications in future children. Otherwise, treatment could be discontinued after 1 year postpartum.

Treatment may consist of surgery in the case of tumors, lower doses of estrogen in the case of exogenously-mediated estrogen excess, and estrogen-suppressing medications like gonadotropin-releasing hormone analogues and progestogens. In addition, androgens may be supplemented in the case of males.

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.

A 2017 review concluded that while both myo-inositol and D-chiro-inositols may regulate menstrual cycles and improve ovulation, there is a lack of evidence regarding effects on the probability of pregnancy. A 2012 and 2017 review have found myo-inositol supplementation appears to be effective in improving several of the hormonal disturbances of PCOS. A 2011 review found not enough evidence to conclude any beneficial effect from D-chiro-inositol. There is insufficient evidence to support the use of acupuncture.

When appropriate (e.g., in women of child-bearing age who require contraception), a standard contraceptive pill is frequently effective in reducing hirsutism. Progestogens such as norgestrel and levonorgestrel should be avoided due to their androgenic effects.

Other drugs with anti-androgen effects include flutamide, and spironolactone, which can give some improvement in hirsutism. Metformin can reduce hirsutism, perhaps by reducing insulin resistance, and is often used if there are other features such as insulin resistance, diabetes, or obesity that should also benefit from metformin. Eflornithine (Vaniqa) is a drug that is applied to the skin in cream form, and acts directly on the hair follicles to inhibit hair growth. It is usually applied to the face. 5-alpha reductase inhibitors (such as finasteride and dutasteride) may also be used; they work by blocking the conversion of testosterone to dihydrotestosterone (the latter of which responsible for most hair growth alterations and androgenic acne).

Although these agents have shown significant efficacy in clinical trials (for oral contraceptives, in 60–100% of individuals), the reduction in hair growth may not be enough to eliminate the social embarrassment of hirsutism, or the inconvenience of plucking or shaving. Individuals vary in their response to different therapies. It is usually worth trying other drug treatments if one does not work, but drug treatments do not work well for all individuals.

Levothyroxine is a stereoisomer of thyroxine which is degraded much slower and can be administered once daily in patients with hypothyroidism.
