Diabetes mellitus is classified two idiopathic forms types of diabetes, called type 1 {Insulin-dependent diabetes mellitus [IDDM] or juvenile-onset diabetes} and type 2 {Non–insulin-dependent diabetes mellitus [NIDDM] or adult-onset diabetes}. Beyond these two types, there is no agreed-upon standard nomenclature. Various sources have defined "type 3 diabetes" as, among others and gestational diabetes.
To determine whether a patient has type 1 or type 2 diabetes is important because patients with type 1 diabetes are dependent on a continuous source of exogenous insulin and carbohydrate for survival. Diabetes
type 1 may also develop in older adults and is increasingly being recognized through the measurement of islet–glutamate decarboxylase (GAD) antibodies. Patients with type 2 diabetes may not need any treatment for hyperglycemia during periods of fasting or decreased oral intake.
Type 1 Diabetes Mellitus
Type 1 diabetes is typically diagnosed in childhood, adolescence, or early adulthood. A patient who has had diabetes since childhood, who has always been dependent on insulin, or who has a history of diabetic ketoacidosis (DKA) almost certainly has type 1 diabetes. People with the new-onset adult (usually before 30 years of age) form of type 1 diabetes mellitus called latent autoimmune diabetes of the adult (LADA).
Type 1 diabetes mellitus currently only can be treated with insulin therapy and this treatment must be continued indefinitely. Family history, diet, and environmental factors are risk factors for type 1 diabetes. Those people who has diagnosed as type 1 diabetes, They need to careful monitoring of blood glucose levels using blood testing monitors. Especially the Children who has significant dehydration, persistent vomiting, serious intercurrent illness, require inpatient management and intravenous rehydration.
Type 1 Diabetes Mellitus
Type 2 diabetes has replaced several former terms, including adult-onset diabetes, obesity-related diabetes, and non-insulin-dependent diabetes (NIDDM). Type 2 diabetes mellitus is much more common and is the type of diabetes that affects most Singaporeans. Type 2 diabetes they have "insulin resistance", in which the cells and tissues of the body are unable to respond to the insulin produced by the pancreas.
In this cases (Type 2) diabetes which has progressed to require injected insulin, and latent autoimmune diabetes of adults (LADA) some of them also maturity onset diabetes of the young (MODY) which is a group of several single gene disorders with strong family histories that present as type 2 diabetes before 30 years of age. As the disease progresses the impairment of insulin secretion worsens, and therapeutic replacement of insulin often becomes necessary.
