The most common classifications include Type 1 diabetes mellitus, Type 2 diabetes mellitus, gestational diabetes and other specific types.<!--more--><\/p>\n<p><strong>Classification of Diabetes Mellitus<\/strong><br \/>\nDiabetes can be classified into the following general categories:<\/p>\n<ol>\n<li>Type 1 diabetes (due to autoimmune \u03b2-cell destruction, usually leading to absolute insulin deficiency, including latent autoimmune diabetes of adulthood)<\/li>\n<li>Type 2 diabetes (due to a progressive loss of adequate \u03b2-cell insulin secretion frequently on the background of insulin resistance)<\/li>\n<li>Specific types of diabetes due to other causes, e.g., monogenic diabetes syndromes (such as neonatal diabetes and maturity-onset diabetes of the young), diseases of the exocrine pancreas (such as cystic fibrosis and pancreatitis), and drug- or chemical-induced diabetes (such as with glucocorticoid use, in the treatment of HIV\/AIDS, or after organ transplantation)<\/li>\n<li>Gestational diabetes mellitus (diabetes diagnosed in the second or third trimester of pregnancy that was not clearly overt diabetes prior to gestation)<\/li>\n<\/ol>\n<p>Type 1 diabetes and type 2 diabetes are heterogeneous diseases in which clinical presentation and disease progression may vary considerably. Classification is important for determining therapy, but some individuals cannot be clearly classified as having type 1 or type 2 diabetes at the time of diagnosis. Children with type 1 diabetes typically present with the hallmark symptoms of polyuria\/polydipsia, and approximately one-third present with <a href=\"https:\/\/medicalcriteria.com\/web\/diabetic-ketoacidosis-hyperosmolar\/\" target=\"_blank\" rel=\"noopener noreferrer\">diabetic ketoacidosis (DKA)<\/a>. The onset of type 1 diabetes may be more variable in adults; they may not present with the classic symptoms seen in children and may experience temporary remission from the need for insulin. Occasionally, patients with type 2 diabetes may present with DKA. The classification of diabetes type is not always straightforward at presentation and that misdiagnosis is common (e.g., adults with type 1 diabetes misdiagnosed as having type 2 diabetes; individuals with maturity-onset diabetes of the young [MODY] misdiagnosed as having type 1 diabetes, etc.). Although difficulties in distinguishing diabetes type may occur in all age-groups at onset, the diagnosis becomes more obvious over time in people with \u03b2-cell deficiency.<\/p>\n<p>In both type 1 and type 2 diabetes, various genetic and environmental factors can result in the progressive loss of \u03b2-cell mass and\/or function that manifests clinically as hyperglycemia. Once hyperglycemia occurs, patients with all forms of diabetes are at risk for developing the same chronic complications, although rates of progression may differ.<\/p>\n<p>There is debate as to whether slowly progressive autoimmune diabetes with an adult onset should be termed <a href=\"https:\/\/medicalcriteria.com\/web\/diablada\/\" target=\"_blank\" rel=\"noopener noreferrer\">latent autoimmune diabetes in adults (LADA)<\/a> or type 1 diabetes. The clinical priority is awareness that slow autoimmune \u03b2-cell destruction can occur in adults leading to a long duration of marginal insulin secretory capacity. For the purpose of this classification, all forms of diabetes mediated by autoimmune \u03b2-cell destruction are included under the rubric of type 1 diabetes. Use of the term LADA is common and acceptable in clinical practice and has the practical impact of heightening awareness of a population of adults likely to develop overt autoimmune \u03b2-cell destruction, thus accelerating insulin initiation prior to deterioration of glucose control or development of DKA.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>References:<\/strong><\/p>\n<ol>\n<li>Classification and Diagnosis of Diabetes: Standards of Medical Care in Diabetes\u20142021.
