In many cases, neonatal diabetes may be treated with oral sulfonylureas such as glyburide. Physicians may order genetic tests to determine whether or not transitioning from insulin to sulfonylurea drugs is appropriate for a patient.

The transfer from insulin injections to oral glibenclamide therapy seems highly effective for most patients and safe. This illuminates how the molecular understanding of some monogenic form of diabetes may lead to an unexpected change of the treatment in children. This is a spectacular example of how the pharmacogenomic approach improves in a tremendous way the quality of life of the young diabetic patients.

Insulin Therapy

- Long Acting Insulin: (Insulin glargine)-is a hormone that works by lowering levels of blood glucose. It starts to work several hours after an injection and keeps working for 24 hours. It is used to manage blood glucose of diabetics. It is used to treat Type 1 and 2 diabetes in adults and Type 1 diabetes in kids as young as 6 years old.

- Short Acting Insulin (e.g. Novolin or Velosulin)-It works similarly to natural insulin and takes up to 30 minutes and lasts for about 8 hours depending on the dosage used.

- Intermediate Insulin: (e.g. NPH insulin)- Usually taken in combination with a short acting insulin. Intermediate acting insulin starts to activate within the first hour of injecting and enters a period of peak activity lasting for 7 hours.

Sulfonylureas

- Sulfonylureas: This medication signals the pancreas to release insulin and help the body's cells use insulin better. This medicaiton can lower A1C levels ( AIC is defined as a measurement of the blood glucose after previous 2–3 months) by 1-2%.

While there is no cure for JBS, treatment and management of specific symptoms and features of the disorder are applied and can often be successful. Variability in the severity of JBS on a case-by-case basis determines the requirements and effectiveness of any treatment selected.

Pancreatic insufficiency and malabsorption can be managed with pancreatic enzyme replacement therapy, such as pancrelipase supplementation and other related methods.

Craniofacial and skeletal deformities may require surgical correction, using techniques including bone grafts and osteotomy procedures. Sensorineural hearing loss can be managed with the use of hearing aids and educational services designated for the hearing impaired.

Special education, specialized counseling methods and occupational therapy designed for those with mental retardation have proven to be effective, for both the patient and their families. This, too, is carefully considered for JBS patients.

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.

There is no known direct treatment. Current treatment efforts focus on managing the complications of Wolfram syndrome, such as diabetes mellitus and diabetes insipidus.

Chronic hyperglycemia due to any cause can eventually cause blood vessel damage and the microvascular complications of diabetes. The principal treatment goals for people with MODY — keeping the blood sugars as close to normal as possible ("good glycemic control"), while minimizing other vascular risk factors — are the same for all known forms of diabetes.

The tools for management are similar for all forms of diabetes: blood testing, changes in diet, physical exercise, oral hypoglycemic agents, and insulin injections. In many cases these goals can be achieved more easily with MODY than with ordinary types 1 and 2 diabetes. Some people with MODY may require insulin injections to achieve the same glycemic control that another person may attain with careful eating or an oral medication.

When oral hypoglycemic agents are used in MODY, the sulfonylureas remain the oral medication of first resort. When compared to patients with type 2 diabetes, MODY patients are often more sensitive to sulphonylureas, such that a lower dose should be used to initiate treatment to avoid hypoglycaemia. Patients with MODY less often suffer from obesity and insulin resistance than those with ordinary type 2 diabetes (for whom insulin sensitizers like metformin or the thiazolidinediones are often preferred over the sulfonylureas).

There are several classes of anti-diabetic medications available. Metformin is generally recommended as a first line treatment as there is some evidence that it decreases mortality; however, this conclusion is questioned. Metformin should not be used in those with severe kidney or liver problems.

A second oral agent of another class or insulin may be added if metformin is not sufficient after three months. Other classes of medications include: sulfonylureas, thiazolidinediones, dipeptidyl peptidase-4 inhibitors, SGLT2 inhibitors, and glucagon-like peptide-1 analogs. There is no significant difference between these agents. Rosiglitazone, a thiazolidinedione, has not been found to improve long-term outcomes even though it improves blood sugar levels. Additionally it is associated with increased rates of heart disease and death. Angiotensin-converting enzyme inhibitors (ACEIs) prevent kidney disease and improve outcomes in those with diabetes. The similar medications angiotensin receptor blockers (ARBs) do not. A 2016 review recommended treating to a systolic blood pressure of 140 to 150 mmHg.

Injections of insulin may either be added to oral medication or used alone. Most people do not initially need insulin. When it is used, a long-acting formulation is typically added at night, with oral medications being continued. Doses are then increased to effect (blood sugar levels being well controlled). When nightly insulin is insufficient, twice daily insulin may achieve better control. The long acting insulins glargine and detemir are equally safe and effective, and do not appear much better than neutral protamine Hagedorn (NPH) insulin, but as they are significantly more expensive, they are not cost effective as of 2010. In those who are pregnant insulin is generally the treatment of choice.

Vitamin D supplementation to people with type 2 diabetes can improve markers of insulin resistance and HbA1c.

About 80% of all LADA patients initially misdiagnosed with type 2 (and who have GAD antibodies) will become insulin-dependent within 3 to 15 years (according to differing LADA sources).

The treatment for Type 1 diabetes/LADA is exogenous insulin to control glucose levels, prevent further destruction of residual beta cells, reduce the possibility of diabetic complications, and prevent death from diabetic ketoacidosis (DKA). Although LADA may appear to initially respond to similar treatment (lifestyle and medications) as type 2 diabetes, it will not halt or slow the progression of beta cell destruction, and people with LADA will eventually become insulin-dependent. People with LADA have insulin resistance similar to long-term type 1 diabetes; some studies showed that people with LADA have less insulin resistance, compared with those with type 2 diabetes; however, others have not found a difference.

Clinical Trials of NDM

- The research article is entitled, "A Successful Transition to sulfonamides treatment in male infant with novel neonatal diabetes mellitus (NDM) caused by the ABBC8 gene mutation and 3 years follow up". It is a case study on the transitioning of treatments from insulin therapy to sulfonamides therapy. NDM is not initiated by an autoimmune mechanism but mutations in K-sensitve channel, "KCNJ11, ABCC8" and "INS" genes are successful targets for changing treatments from insulin to sulfonamides therapy.

- Introduction: Within this study a two month old male was admitted into the intensive care unit, because the he was showing signs of diabetic ketoacidosis. Other symptoms include, respiratory tract infection, sporous, dehydration, reduced subcutaneous fat, Candida mucous infection. The infant's family history was negative for diseases of importance to hereditary and the eldest sibling was healthy.

- Experiment: The current treatment plan consist of therapy for ketoacidosis was started upon admissions into the hospital. Also, subcutaneous insulin was given (0.025-0.05 units/kg/h) and adjusted to the glycaemic profiles and the patient was converted to euglycaemic state. After 24 hours, oral intake of insulin started and treatment continued with subcutaneous short acting insulin then intermediate acting insulin plus 2 dosage of short acting insulin. A genetic analysis was conducted for NDM and mutation of KCNJ11, "ABCC8" and "INS" genes have been given. Sequence analysis showed a rare heterogeneous missense mutation, PF577L, in the patient's exon 12 of ABCC8 gene. This confirms diagnosis of NDM caused by heterozygous mutation in the SUR1 subunit of the pancreatic ATP-sensitive potassium channel, because his parents' white blood cells did not show signs of this mutation.

- Results: Switching from the insulin therapy to the sulfonamides was a successful treatment. It is the current regimen used to treat NDM.

- Discussion/Conclusion: ABCC8 gene produces SUR1 protein subunit that interacts with pancreatic ATP-sensitive potassium channel. When the channel opens a large amount of insulin is released. Mutations that occur in ABCC8 are associated with congential hyperinsulinism and PNDM or TNDM. Patients that have mutations in their potassium channel, improved their glucose levels with sulfonylurea regimen and glibenclamide showed successful results in managing glucose levels as well.

- A 2006 study showed that 90% of patients with a KCNJ11 mutation were able to successfully transition to sulfonylurea therapy.

Medications used to treat diabetes do so by lowering blood sugar levels. There are a number of different classes of anti-diabetic medications. Some are available by mouth, such as metformin, while others are only available by injection such as GLP-1 agonists. Type 1 diabetes can only be treated with insulin, typically with a combination of regular and NPH insulin, or synthetic insulin analogs.

Metformin is generally recommended as a first line treatment for type 2 diabetes, as there is good evidence that it decreases mortality. It works by decreasing the liver's production of glucose. Several other groups of drugs, mostly given by mouth, may also decrease blood sugar in type II DM. These include agents that increase insulin release, agents that decrease absorption of sugar from the intestines, and agents that make the body more sensitive to insulin. When insulin is used in type 2 diabetes, a long-acting formulation is usually added initially, while continuing oral medications. Doses of insulin are then increased to effect.

Since cardiovascular disease is a serious complication associated with diabetes, some have recommended blood pressure levels below 130/80 mmHg. However, evidence supports less than or equal to somewhere between 140/90 mmHg to 160/100 mmHg; the only additional benefit found for blood pressure targets beneath this range was an isolated decrease in stroke risk, and this was accompanied by an increased risk of other serious adverse events. A 2016 review found potential harm to treating lower than 140 mmHg. Among medications that lower blood pressure, angiotensin converting enzyme inhibitors (ACEIs) improve outcomes in those with DM while the similar medications angiotensin receptor blockers (ARBs) do not. Aspirin is also recommended for people with cardiovascular problems, however routine use of aspirin has not been found to improve outcomes in uncomplicated diabetes.

Oral medications like Glipizide that stimulate the pancreas, promoting insulin release (or in some cases, reduce glucose production), are less and less used in cats, and these drugs may be completely ineffective if the pancreas is not working. These drugs have also been shown in some studies to damage the pancreas further or to cause liver damage. Some owners are reluctant to switch from pills to insulin injections, but the fear is unjustified; the difference in cost and convenience is minor (most cats are easier to inject than to pill), and injections are more effective at treating the disease.

A proper diet and exercise are the foundations of diabetic care, with a greater amount of exercise yielding better results. Aerobic exercise leads to a decrease in HbA and improved insulin sensitivity. Resistance training is also useful and the combination of both types of exercise may be most effective. A diabetic diet that promotes weight loss is important. While the best diet type to achieve this is controversial, a low glycemic index diet or low carbohydrate diet has been found to improve blood sugar control. Culturally appropriate education may help people with type 2 diabetes control their blood sugar levels, for up to 24 months. If changes in lifestyle in those with mild diabetes has not resulted in improved blood sugars within six weeks, medications should then be considered. There is not enough evidence to determine if lifestyle interventions affect mortality in those who already have DM2. Vegetarian diets in general have been related to lower diabetes risk, but do not offer advantages compared with diets which allow moderate amounts of animal products. There is not enough evidence to suggest that cinnamon improves blood sugar levels in people with type 2 diabetes.

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.

Diabetes can be treated but is life-threatening if left alone. Early diagnosis and treatment by a qualified veterinarian can help in preventing nerve damage, and, in rare cases, lead to remission. Cats do best with long-lasting insulin and low carbohydrate diets. Because diabetes is a disease of carbohydrate metabolism, a move to a primarily protein and fat diet reduces the occurrence of hyperglycemia.

There is evidence that prediabetes is a curable disease state. Intensive weight loss and lifestyle intervention, if sustained, may improve glucose tolerance substantially and prevent progression from IGT to type 2 diabetes. The Diabetes Prevention Program (DPP) study found a 16% reduction in diabetes risk for every kilogram of weight loss. Reducing weight by 7% through a low-fat diet and performing 150 minutes of exercise a week is the goal. In observational studies, individuals following vegetarian diets are about half as likely to develop diabetes, compared with non-vegetarians. The ADA guidelines recommend modest weight loss (5–10% body weight), moderate-intensity exercise (30 minutes daily), and smoking cessation.

There are claims in the media that a high-fat, high-protein, low carbohydrates diet can reverse prediabetes, but scientific evidence is not conclusive as to whether this diet has any efficacy.

For patients with severe risk factors, prescription medication may be appropriate. This may be considered in patients for whom lifestyle therapy has failed, or is not sustainable, and who are at high-risk for developing type 2 diabetes. Metformin and acarbose help prevent the development of frank diabetes, and also have a good safety profile. Evidence also supports thiazolidinediones but there are safety concerns, and data on newer agents such as GLP-1 receptor agonists, DPP4 inhibitors or meglitinides are lacking.

People with diabetes can benefit from education about the disease and treatment, good nutrition to achieve a normal body weight, and exercise, with the goal of keeping both short-term and long-term blood glucose levels within acceptable bounds. In addition, given the associated higher risks of cardiovascular disease, lifestyle modifications are recommended to control blood pressure.

There is no single dietary pattern that is best for all people with diabetes. For overweight people with type 2 diabetes, any diet that the person will adhere to and achieve weight loss on is effective.

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.

Research for designing therapeutic trials is ongoing via the Washington University Wolfram Study Group, supported by The Ellie White Foundation for Rare Genetic Disorders and The Jack and J.T. Snow Scientific Research Foundation for Wolfram research.

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.

Statins (or HMG-CoA reductase inhibitors) are commonly used to treat hypercholesterolemia if diet is ineffective. Other agents that may be used include: fibrates, nicotinic acid, and cholestyramine. These, however, are only recommended if statins are not tolerated or in pregnant women. Statins can reduce total cholesterol by about 50% in the majority of people; effects appear similar regardless of the statin used. While statins are effective in decreasing mortality in those who have had previous cardiovascular disease, debate exists over whether or not they are effective in those with high cholesterol but no other health problems. One review did not find a mortality benefit in those at high risk, but without prior cardiovascular disease. Other reviews concluded a mortality benefit does exist. Statins may improve quality of life when used in people without existing cardiovascular disease (i.e. for primary prevention). Statins decrease cholesterol in children with hypercholesterolemia, but no studies as of 2010 show improved clinical outcomes and diet is the mainstay of therapy in childhood. Injectable antibodies against the protein PCSK9 (evolocumab, bococizumab, alirocumab) can reduce LDL cholesterol and have been shown to reduce mortality.

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.

Diabetes mellitus may be effectively managed by appropriate meal planning, increased physical activity and properly-instituted insulin treatment. Some tips for controlling diabetes in pregnancy include:

- Meals – Cut down sweets, eats three small meals and one to three snacks a day, maintain proper mealtimes, and include balanced fiber intake in the form of fruits, vegetables and whole-grains.

- Increased physical activity - walking, swimming/aquaerobics, etc.

- Monitor blood sugar level frequently, doctors may ask to check the blood glucose more often than usual.

- The blood sugar level should be below 95 mg/dl (5.3 mmol/l) on awakening, below 140 mg/dl (7.8 mmol/l) one hour after a meal and below 120 mg/dl (6.7 mmol/l) two hours after a meal.

- Each time when checking the blood sugar level, keep a proper record of the results and present to the health care team for evaluation and modification of the treatment. If blood sugar levels are above targets, a perinatal diabetes management team may suggest ways to achieve targets.

- Many may need extra insulin during pregnancy to reach their blood sugar target. Insulin is not harmful for the baby.

In some forms of MODY, standard treatment is appropriate, though exceptions occur:

- In MODY2, oral agents are relatively ineffective and insulin is unnecessary.

- In MODY1 and MODY3, insulin may be more effective than drugs to increase insulin sensitivity.

- Sulfonylureas are effective in the K channel forms of neonatal-onset diabetes. The mouse model of MODY diabetes suggested that the reduced clearance of sulfonylureas stands behind their therapeutic success in human MODY patients, but Urbanova et al. found that human MODY patients respond differently to the mouse model and that there was no consistent decrease in the clearance of sulfonylureas in randomly selected HNF1A-MODY and HNF4A-MODY patients.

There are no known ways of preventing LADA type 1 diabetes, though some researchers believe it could be stopped at a very early stage if a diagnosis is made prior to the body's destruction of its beta cells.

Acute hypoglycemia is reversed by raising the blood glucose. Glucagon should be injected intramuscularly or intravenously, or dextrose can be infused intravenously to raise the blood glucose. Oral administration of glucose can worsen the outcome, as more insulin is eventually produced. Most people recover fully even from severe hypoglycemia after the blood glucose is restored to normal. Recovery time varies from minutes to hours depending on the severity and duration of the hypoglycemia. Death or permanent brain damage resembling stroke can occur rarely as a result of severe hypoglycemia. See hypoglycemia for more on effects, recovery, and risks.

Further therapy and prevention depends upon the specific cause.

Most hypoglycemia due to excessive insulin occurs in people who take insulin for type 1 diabetes. Management of this hypoglycemia is sugar or starch by mouth (or in severe cases, an injection of glucagon or intravenous dextrose). When the glucose has been restored, recovery is usually complete. Prevention of further episodes consists of maintaining balance between insulin, food, and exercise. Management of hypoglycemia due to treatment of type 2 diabetes is similar, and the dose of the oral hypoglycemic agent may need to be reduced. Reversal and prevention of hypoglycemia is a major aspect of the management of type 1 diabetes.

Hypoglycemia due to drug overdose or effect is supported with extra glucose until the drugs have been metabolized. The drug doses or combination often needs to be altered.

Hypoglycemia due to a tumor of the pancreas or elsewhere is usually curable by surgical removal. Most of these tumors are benign. Streptozotocin is a specific beta cell toxin and has been used to treat insulin-producing pancreatic carcinoma.

Hyperinsulinism due to diffuse overactivity of beta cells, such as in many of the forms of congenital hyperinsulinism, and more rarely in adults, can often be treated with diazoxide or a somatostatin analog called octreotide. Diazoxide is given by mouth, octreotide by injection or continuous subcutaneous pump infusion. When congenital hyperinsulinism is due to focal defects of the insulin-secretion mechanism, surgical removal of that part of the pancreas may cure the problem. In more severe cases of persistent congenital hyperinsulinism unresponsive to drugs, a near-total pancreatectomy may be needed to prevent continuing hypoglycemia. Even after pancreatectomy, continuous glucose may be needed in the form of gastric infusion of formula or dextrose.

High dose glucocorticoid is an older treatment used for presumptive transient hyperinsulinism but incurs side effects with prolonged 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.
