Permanent neonatal diabetes mellitus

Nonsyndromic permanent neonatal diabetes mellitus (PNDM) is characterized by the onset of hyperglycemia within the first six months of life (mean age: 7 weeks; range: birth to 26 weeks) that does not resolve over time. Clinical manifestations at the time of diagnosis include intrauterine growth retardation (IUGR), hyperglycemia, glycosuria, osmotic polyuria, severe dehydration, and failure to thrive. Therapy with insulin corrects the hyperglycemia and allows for catch-up growth. The course of PNDM varies by genotype. Pancreatic agenesis/hypoplasia caused by homozygous mutations in PDX1 results in severe insulin deficiency and exocrine pancreatic insufficiency. [from GeneReviews]

Persistent hyperinsulinemic hypoglycemia of infancy

Familial hyperinsulinism (referred to as FHI in this GeneReview) is characterized by hypoglycemia that ranges from severe neonatal-onset, difficult-to-manage disease to childhood-onset disease with mild symptoms and difficult-to-diagnose hypoglycemia. Neonatal-onset disease manifests within hours to two days after birth. Childhood-onset disease manifests during the first months or years of life. In the newborn period, presenting symptoms may be nonspecific, including seizures, hypotonia, poor feeding, and apnea. In severe cases, serum glucose concentrations are typically extremely low and thus easily recognized, whereas in milder cases, variable and mild hypoglycemia may make the diagnosis more difficult. Even within the same family, disease manifestations can range from mild to severe. Individuals with autosomal recessive familial hyperinsulinism, caused by mutations in either ABCC8 or KCNJ11 (FHI-KATP), tend to be large for gestational age and usually present with severe refractory hypoglycemia in the first 48 hours of life; affected infants usually respond only partially to diet or medical management (i.e., diazoxide therapy) and thus may require pancreatic resection. Individuals with autosomal dominant FHI-KATP tend to be appropriate for gestational age at birth, to present at approximately age one year (range: 2 days - 30 years), and to respond to diet and diazoxide therapy. Exceptions to both of these generalities have been reported. FHI-GCK, caused by mutations in GCK, may be much milder than FHI-KATP; however, some persons have severe, diazoxide-unresponsive hypoglycemia. FHI-HADH, caused by mutations in HADH, tends to be relatively mild, although severe cases have been reported. Individuals with FHI-HNF4A, caused by mutations in HNF4A, are typically born large for gestational age and have mild features that respond to diazoxide treatment. FHI-UCP2, caused by mutations in UCP2, is a rare cause of diazoxide-responsive FH1. Hyperammonemia/hyperinsulinism (HA/HI) is associated with mild-to-moderate hyperammonemia and with relatively mild, late-onset hypoglycemia; most but not all affected individuals have mutations in GLUD1. [from GeneReviews]

Diabetes mellitus type 2

Diabetes means your blood glucose, or blood sugar, levels are too high. With type 2 diabetes, the more common type, your body does not make or use insulin well. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth. You have a higher risk of type 2 diabetes if you are older, obese, have a family history of diabetes, or do not exercise. The symptoms of type 2 diabetes appear slowly. Some people do not notice symptoms at all. The symptoms can include: -Being very thirsty. -Urinating often. -Feeling very hungry or tired. -Losing weight without trying. -Having sores that heal slowly. -Having blurry eyesight. A blood test can show if you have diabetes. Many people can manage their diabetes through healthy eating, physical activity, and blood glucose testing. Some people also need to take diabetes medicines. NIH: National Institute of Diabetes and Digestive and Kidney Diseases.  [from MedlinePlus]
