Medications that are sometimes required include estrogen replacement therapy in postmenopausal women and bisphosphonates. Bisphosphonates may improve bone turnover.

Newer medications termed "calcimimetics" used in secondary hyperparathyroidism are now being used in primary hyperparathyroidism. Calcimimetics reduce the amount of parathyroid hormone released by the parathyroid glands. They are recommended in patients in whom surgery is inappropriate.

Medical management of OFC consists of Vitamin D treatment, generally alfacalcidol or calcitriol, delivered intravenously. Studies have shown that in cases of OFC caused by either end-stage renal disease or primary hyperparathyoidism, this method is successful not only in treating underlying hyperparathyoidism, but also in causing the regression of brown tumors and other symptoms of OFC.

Severe hypocalcaemia, a potentially life-threatening condition, is treated as soon as possible with intravenous calcium (e.g. as calcium gluconate). Generally, a central venous catheter is recommended, as the calcium can irritate peripheral veins and cause phlebitis. In the event of a life-threatening attack of low calcium levels or tetany (prolonged muscle contractions), calcium is administered by intravenous (IV) infusion. Precautions are taken to prevent seizures or larynx spasms. The heart is monitored for abnormal rhythms until the person is stable. When the life-threatening attack has been controlled, treatment continues with medicine taken by mouth as often as four times a day.

Long-term treatment of hypoparathyroidism is with vitamin D analogs and calcium supplementation, but may be ineffective in some due to potential renal damage. The N-terminal fragment of parathyroid hormone (PTH 1-34) has full biological activity. The use of pump delivery of synthetic PTH 1-34 provides the closest approach to physiologic PTH replacement therapy. Injections of recombinant human parathyroid hormone are available as treatment in those with low blood calcium levels.

Treatment is usually surgical removal of the gland(s) containing adenomas, but medication may also be required.

In especially severe cases of OFC, parathyroidectomy, or the full removal of the parathyroid glands, is the chosen route of treatment. Parathyroidectomy has been shown to result in the reversal of bone resorption and the complete regression of brown tumors. In situations where parathyroid carcinoma is present, surgery to remove the tumors has also led to the regression of hyperparathyroidism as well as the symptoms of OFC.

Bone transplants have proven successful in filling the lesions caused by OFC. A report showed that in 8 out of 11 instances where cavities caused by OFC were filled with transplanted bone, the lesion healed and the transplanted bone blended rapidly and seamlessly with the original bone.

In people with secondary hyperparathyroidism, the high PTH levels are an appropriate response to low calcium and treatment must be directed at the underlying cause of this (usually vitamin D deficiency or chronic kidney failure). If this is successful PTH levels should naturally return to normal levels unless PTH secretion has become autonomous (tertiary hyperparathyroidism)

Treatment depends entirely on the type of hyperparathyroidism encountered.

Bisphosphonates are useful in decreasing the risk of future fractures in those who have already sustained a fracture due to osteoporosis. This benefit is present when taken for three to four years. Different bisphosphonates have not been directly compared, therefore it is unknown if one is better than another. Fracture risk reduction is between 25 and 70% depending on the bone involved. There are concerns of atypical femoral fractures and osteonecrosis of the jaw with long-term use, but these risks are low. With evidence of little benefit when used for more than three to five years and in light of the potential adverse events, it may be appropriate to stop treatment after this time. One medical organization recommends that after five years of medications by mouth or three years of intravenous medication among those at low risk, bisphosphonate treatment can be stopped. In those at higher risk they recommend up to ten years of medication by mouth or six years of intravenous treatment.

For those with osteoporosis but who have not had a fracture evidence does not support a reduction in fracture risk with risedronate or etidronate. Alendronate decreases fractures of the spine but does not have any effect on other types of fractures. Half stop their medications within a year. When on treatment with bisphosphonates rechecking bone mineral density is not needed. Another review found tentative evidence of benefit in males with osteoporosis.

Fluoride supplementation does not appear to be effective in postmenopausal osteoporosis, as even though it increases bone density, it does not decrease the risk of fractures.

Teriparatide ( a recombinant parathyroid hormone ) has been shown to be effective in treatment of women with postmenopausal osteoporosis. Some evidence also indicates strontium ranelate is effective in decreasing the risk of vertebral and nonvertebral fractures in postmenopausal women with osteoporosis. Hormone replacement therapy, while effective for osteoporosis, is only recommended in women who also have menopausal symptoms. It is not recommended for osteoporosis by itself. Raloxifene, while effective in decreasing vertebral fractures, does not affect the risk of nonvertebral fracture. And while it reduces the risk of breast cancer, it increases the risk of blood clots and strokes. Denosumab is also effective for preventing osteoporotic fractures but not in males. In hypogonadal men, testosterone has been shown to improve bone quantity and quality, but, as of 2008, no studies evaluated its effect on fracture risk or in men with a normal testosterone levels. Calcitonin while once recommended is no longer due to the associated risk of cancer and questionable effect on fracture risk.

Certain medications like alendronate, etidronate, risedronate, raloxifene and strontium ranelate can be helpful for the preventing of osteoporotic fragility fractures in postmenopausal women with osteoporosis.

Treatment for renal osteodystrophy includes the following:

- calcium and/or native vitamin D supplementation

- restriction of dietary phosphate (especially inorganic phosphate contained in additives)

- phosphate binders such as calcium carbonate, calcium acetate, sevelamer hydrochloride or carbonate, lanthanum carbonate, sucroferric oxyhydroxide, ferric citrate among others

- active forms of vitamin D (calcitriol, alfacalcidol, paricalcitol, maxacalcitol, doxercalciferol, among others)

- cinacalcet

- renal transplantation

- haemodialysis five times a week is thought to be of benefit

- parathyroidectomy for symptomatic medication refractive end stage disease

The goal of therapy is to treat the hypercalcaemia first and subsequently effort is directed to treat the underlying cause.

Weight-bearing endurance exercise and/or exercises to strengthen muscles improve bone strength in those with osteoporosis. Aerobics, weight bearing, and resistance exercises all maintain or increase BMD in postmenopausal women. Fall prevention can help prevent osteoporosis complications. There is some evidence for hip protectors specifically among those who are in care homes.

Initial therapy:

- hydration, increasing salt intake, and forced diuresis.

- hydration is needed because many patients are dehydrated due to vomiting or kidney defects in concentrating urine.

- increased salt intake also can increase body fluid volume as well as increasing urine sodium excretion, which further increases urinary potassium excretion.

- after rehydration, a loop diuretic such as furosemide can be given to permit continued large volume intravenous salt and water replacement while minimizing the risk of blood volume overload and pulmonary oedema. In addition, loop diuretics tend to depress calcium reabsorption by the kidney thereby helping to lower blood calcium levels

- can usually decrease serum calcium by 1–3 mg/dL within 24 hours

- caution must be taken to prevent potassium or magnesium depletion

Recovery from renal osteodystrophy has been observed following kidney transplantation. Renal osteodystrophy is a chronic condition with a conventional hemodialysis schedule. Nevertheless, it is important to consider that the broader concept of CKD-MBD, which includes renal osteodystrophy, is not only associated with bone disease and increased risk of fractures but also with cardiovascular calcification, poor quality of life and increased morbidity and mortality in CKD patients (the so-called bone-vascular axis). Actually, bone may now be considered a new endocrine organ at the heart of CKD-MBD.

People with acanthosis nigricans should be screened for diabetes and, although rare, cancer. Controlling blood glucose levels through exercise and diet often improves symptoms. Topical fade creams (normally used for eliminating age spots) can lighten skin cosmetically in less severe cases. Acanthosis nigricans maligna may resolve if the causative tumor is successfully removed.

Alternatively, a single-dose therapy is used for instance if there are concerns regarding the patient's compliance. The single-dose therapy can be given as an injection, but is normally given in form of an oral medication.

For treating rickets, the American Academy of Pediatrics (AAP) has recommended that pediatric patients receive an initial two- to three-month treatment of "high-dose" vitamin D therapy. In this regime, the daily dose of cholecalciferol is 1,000 IU for newborns, 1,000 to 5,000 IU for 1- to 12-months old infants, and 5,000 IU for patients over 1 year of age.

For adults, other dosages have been called for. A review of 2008/2009 recommended dosages of 1,000 IU cholecalciferol per 10 ng/ml required serum increase, to be given daily over two to three months. In another proposed cholecalciferol loading dose guideline for vitamin D-deficient adults, a weekly dosage is given, up to a total amount that is proportional to the required serum increase (up to the level of 75 nml/l) and, within certain body weight limits, to body weight.

Bone disease is common among the elderly individual, but adolescents can be diagnosed with this disorder as well. There are many bone disorders such as osteoporosis, Paget's disease, hypothyroidism. Although there are many forms of bone disorders, they all have one thing in common; abnormalities of specific organs involved, deficiency in vitamin D or low Calcium in diet, which results in poor bone mineralization.

Thyroid, parathyroid, pituitary, adrenal and pancreases are common are part of the endocrine system and therefore are associated with bone disease. Some common endocrine disorders are hypothyroidism, hyperthyroidism, Paget’s disease, Osteoporosis, and diabetes. The thyroid gland produces thyroxin (T3, and T4) which is necessary for normal development of nervous system, it function includes: promoting growth, increasing basal metabolic rate and controls body temperature. Adequate Iodine, found in salt fish water, shrimp is necessary for the production of thyroid hormone. According to Payton R. G et al., common disorder of the thyroid gland is hypothyroidism which is common in women than men. Symptoms of hypothyroidism include cold intolerance, weight gain, fatigue, anemia, difficulty concentrating, amenorrhea, bradycardia (low heart rate) and goitre. Another hormone that is secreted by Para follicular cells of the thyroid gland is calcitonin. Calcitonin works in an antagonistic fashion with parathyroid hormone (PTH): both regulate the level of calcium in the blood. Blood calcium level is tightly regulated by these two hormones. The cells of our bone that is involved in bone formation and bone breakdown is osteoblast and osteoclast respectively. Osteoclasts are cells of bones that promote bone demineralization or bone resorption. In contrast, Osteoblast promotes calcium absorption by the bone therefore, promoting bone mineralization and formation of new bones. Thus Calcitonin activates osteoblasts, therefore decrease blood calcium levels by decreasing bone breakdown (resorption) by inhibiting osteoclast. Whereas, PTH activates osteoclast and thereby increases blood calcium. The hormone produced by the thyroid gland has big impact on bone density, blood calcium levee. Abnormalities of the thyroid gland impact bone disease such as osteoporosis, a condition that is common in women but men can be diagnosed with this silent disease as well as it mainly affects elderly individual.

In addition to thyroid gland, Vitamin D plays crucial role in absorption of calcium. In fact, Vitamin D is needed for efficient absorption of calcium and therefore proper bone health. Vitamin D is a fat-soluble vitamin, as well, it is unique because it is considered as a hormone; synthesized endogenously in the liver in form of Cholecalciferol. The endogenous inactive form of Vitamin D is Cholecalciferol or Vitamin D3 which is converted to active form of Vitamin D–Calcitriol also known as 1, 25-Dihydroxycholecalciferol in the Kidney upon exposure to UV ray of sun light. Deficiency in Vitamin D or renal disease contributes to bone disorder such as in Osteomalacia in adult and Rickets in children. Osteomalacia is the softening of bones due to poor bone mineralization which is in turn due to poor calcium absorption. Ultimately, these hormonal changes in body; such as function of thyroid, parathyroid, liver and kidney disrupts metabolic changes as well as function of specific organs, which in turn leads to condition that are not desirable such as bone disorders or other endocrine related diseases.

The cost of treatment depends on the amount of growth hormone given, which in turn depends on the child's weight and age. One year's worth of drugs normally costs about US $20,000 for a small child and over $50,000 for a teenager. These drugs are normally taken for five or more years.

In endocrinology, medical emergencies include diabetic ketoacidosis, hyperosmolar hyperglycemic state, hypoglycemic coma, acute adrenocortical insufficiency, phaeochromocytoma crisis, hypercalcemic crisis, thyroid storm, myxoedema coma and pituitary apoplexy.

Emergencies arising from decompensated pheochromocytomas or parathyroid adenomas are sometimes referred for emergency resection when aggressive medical therapies fail to control the patient's state, however the surgical risks are significant, especially blood pressure lability and the possibility of cardiovascular collapse after resection (due to a brutal drop in respectively catecholamines and calcium, which must be compensated with gradual normalization). It remains debated when emergency surgery is appropriate as opposed to urgent or elective surgery after continued attempts to stabilize the patient, notably in view of newer and more efficient medications and protocols.

Treatment options depend on the type of tumor and on its size:

- Prolactinomas are most often treated with cabergoline or quinagolide (both dopamine agonists), which decrease tumor size as well as alleviates symptoms, followed by serial imaging to detect any increase in size. Treatment where the tumor is large can be with radiation therapy or surgery, and patients generally respond well. Efforts have been made to use a progesterone antagonist for the treatment of prolactinomas, but so far have not proved successful.

- Somatotrophic adenomas respond to octreotide, a long-acting somatostatin analog, in many but not all cases according to a review of the medical literature. Unlike prolactinomas, thyrotrophic adenomas characteristically respond poorly to dopamine agonist treatment.

- Surgery is a common treatment for pituitary tumors. The normal approach is Trans-sphenoidal adenectomy, which usually can remove the tumor without affecting the brain or optic nerves.

- Danazol is a steroid compound that has been labelled as an "Anterior pituitary suppressant".

After diagnosis, it is important for patients to be continually monitored. The most common treatment for PPNAD is bilateral laparoscopic adrenalectomy; the process by which both adrenal glands are removed by a small incision.

Patients who have received this treatment will be prescribed mineralocorticoid and glucocorticoid steroids as they are no longer being naturally produced.

This is a treatment which has been used and refined since 1984.

Treatment in fibrous dysplasia is mainly palliative, and is focused on managing fractures and preventing deformity. There are no medications capable of altering the disease course. Intravenous bisphosphonates may be helpful for treatment of bone pain, but there is no clear evidence that they strengthen bone lesions or prevent fractures. Surgical techniques that are effective in other disorders, such as bone grafting, curettage, and plates and screws, are frequently ineffective in fibrous dysplasia and should be avoided. Intramedullary rods are generally preferred for management of fractures and deformity in the lower extremities. Progressive scoliosis can generally be managed with standard instrumentation and fusion techniques. Surgical management in the craniofacial skeleton is complicated by frequent post-operative FD regrowth, and should focus on correction of functional deformities. Prophylactic optic nerve decompression increases the risk of vision loss and is contraindicated.

Managing endocrinopathies is a critical component of management in FD. All patients with fibrous dysplasia should be evaluated and treated for endocrine diseases associated with McCune–Albright syndrome. In particular untreated growth hormone excess may worsen craniofacial fibrous dysplasia and increase the risk of blindness. Untreated hypophosphatemia increases bone pain and risk of fractures.

Clinical trials of protein kinase inhibitors, which block the abnormal kinase proteins involved in the development and growth of medullary cancer cells, showed clear evidence of response in 10-30% of patients. In the majority of responders there has been less than a 30% decrease in tumor mass, yet the responses have been durable; responses have been stable for periods exceeding 3 years. The major side effects of this class of drug include hypertension, nausea, diarrhea, some cardiac electrical abnormalities, and thrombotic or bleeding episodes.

Vandetanib, trade name Caprelsa, was the first drug (April 2011) to be approved by US Food and Drug Administration (FDA) for treatment of late-stage (metastatic) medullary thyroid cancer in adult patients who are ineligible for surgery.

Cabozantinib, trade name Cometriq, was granted marketing approval (November 2012) by the U.S. FDA for this indication. Cabozantinib which is a potent inhibitor of RET, MET and VEGF was evaluated in a double-blind placebo controlled trial. It was shown to improve overall survival by 5 months for the treated cohort vs. placebo, which was not statistically significant. However, cabozantinib was particularly effective in patients with the RET M918T mutation, extending overall survival by roughly 2 years, doubling survival vs. untreated patient (4 years vs. 2 year). Treatment with cabozantinib did require many dose reduction to mitigate side effects. It has been suggested that the trial dose of 140 mg was excessive, particularly in lower body mass patients. Ongoing trials have been scheduled to identify more optimal dosing regimes. Activity has been observed, in practice at doeses of 1.2 mg/kg.

Acanthosis nigricans is likely to improve in circumstances where a known cause is removed. For example, obesity-related acanthosis nigricans will improve with weight loss, and drug-induced acanthosis nigricans is likely to resolve when the drug is ceased. Hereditary variants may or may not fade with age, and malignancy-associated variants may, after a malignancy is removed, fade.
