What is Diabetes Mellitus? Diabetes UK defines Diabetes Mellitus (DM) ‘’as a serious, lifelong condition where the blood glucose levels is too high resulting in chronic vascular complications’’ (Diabetes UK, 2018). Diabetes Mellitus is a group of metabolic diseases characterized by chronic hyperglycaemia resulting from defects in insulin secretion, insulin action or both. It is associated with long-term irreversible damage, dysfunction and failure of various organs, especially the eyes, kidneys, nerves, heart and blood vessels (American Diabetes Association, 2018)

Global estimates for 2015 -2040 Recent estimates suggest that the number of people with diabetes across the world will increase from 415 million in 2015 to 642 million by 2040. The global cost of diabetes is set to almost double to $2. 5 trillion by 2030 finds research from King’s College London (March, 2018). It suggests that even if countries meet internationally set management targets, the global economic burden from the disease will still increase by 88%. This is calculated by looking at costs from medical care and costs incurred through loss of productivity and earnings in 180 countries across the world.
Prevalence of Diabetes Mellitus Prevalence 2016 - 2017 England 3, 116, 399 Northern Ireland 92, 480 Scotland 289, 040 Wales 191, 590 UK 3, 689, 509
Prevalence of Diabetes Mellitus
Diabetes Watch on-line tool NHS West Essex CCG ( 2015 -16) Population of 242, 088 Percentage of people >17 diagnosed with diabetes 6% of the registered population : 14, 610 The total number of people with diabetes in WECCG to rise to 27, 301 by 2035 A further 27, 769 are at risk of developing Type 2 Diabetes in WECCG according to statistics from PHE (2015), NHS DPP(non-diabetic hyperglycaemia)
Risk factors Age Ethnicity Family history and Genetics Environmental Infections Lifestyle and acquired behaviours : smoking, harmful chronic alcohol consumption, Western diet, chronic excess of refined sugars, high sat fat and high calorie intake coupled with a sedentary lifestyle leads to obesity and insulin resistance Psychological or physical trauma (i. e. car accidents)
Higher risks Following a heart attack or a stroke In patients with schizophrenia, bipolar illness or depression, or patients receiving treatment with antipsychotic medication In patients with chronic respiratory diseases receiving steroids In inherited familial hypercholesterolemia In women with polycystic ovaries syndrome (PCOS), gestational diabetes, or having a baby weighing over 10 pounds.
Symptoms The common symptoms of diabetes Frequent urination, especially at night (Polyuria). Excessive thirst (Polydipsia) Polyphagia Increased Tiredness Unintentional weight loss Genital itching or thrush ( Chronic Candidiasis). Slow wound healing Blurred vision.
WHO Diagnostic criteria Diabetes symptoms and: a random venous plasma glucose concentration (RPG) ≥ 11. 1 mmol/l or a fasting plasma glucose concentration(FPG) ≥ 7. 0 mmol/l or (whole blood ≥ 6. 1 mmol/l) or two hour plasma glucose concentration ≥ 11. 1 mmol/l two hours after ingestion of 75 g anhydrous glucose in an oral glucose tolerance test (OGTT).
Haemoglobin A 1 c (Hb. A 1 c) testing to diagnose diabetes since 2011 An Hb. A 1 c of 48 mmol/mol (6. 5%) is recommended as the cut off point for diagnosing diabetes. A value of less than 48 mmol/mol (6. 5%) does not exclude diabetes (high risk) and repeat test after 6 months
Impaired Glucose Regulation (IGR) IGR- risk factor future diabetes and adverse outcomes Above euglycaemia but not high enough to diagnose Type 2 Diabetes Impaired Fasting Glucose (IFG) 6. 1 -6. 9 mmol/L Impaired Glucose Tolerance (IGT) defined as IFG<7. 0 and 2 hr-PG (after 75 g Glucose load) 7. 811. 0 mmol/L
Classification of DM & causes Type 1 Diabetes Mellitus~ 10% Type 2 Diabetes Mellitus~ 90% Immune-mediated destruction of pancreatic beta-cells Prevalent throughout life Requires insulin replacement therapy for life Short onset of 1 -2 weeks, accelerated weight loss DKA at presentation Slow progressive decrease in insulin secretion associated with insulin resistance Overweight/obese Treated initially with diet, physical activity, then OHA’s and other insulin or noninsulin injectable medication
Type 1 DM: genetics Auto-immune disorders Auto-immune destruction of beta-cells Grave’s disease Hashimoto’s thyroiditis Addison’s disease Vitiligo Celiac disease auto-immune hepatitis Myasthenia Gravis Pernicious anaemia Genetic predisposition ( HLADQA 1, DQB 1, DRB 1 variants) related to environmental factors poorly defined The HLA (human leukocyte antigen) complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders, such as viruses and bacteria.
T 2 DM: genetics Gene mutations These include genes that control: production of glucose production and regulation of insulin how glucose levels are sensed in the body Gene associated with T 2 TCF 7 L 2, which affects insulin secretion and glucose production ABCC 8, which helps regulate insulin CAPN 10, which is associated with type 2 diabetes risk in Mexican-Americans GLUT 2, which helps move glucose into the pancreas GCGR, a glucagon hormone involved in glucose regulation
Classification of DM and causes Gestational Diabetes (GDM) Other types : LADA, Ketone prone Diabetes (Flatbush) Genetic defects of the beta-cells: maturity-onset diabetes of the young (MODY) characterized by impaired insulin secretion with minimal or no defects in insulin action. Abnormalities on different chromosomes have been identified. Genetic defects in insulin action associated with mutations of the insulin receptors (hyperinsulinemia and hyperglycaemia) Diseases of the exocrine pancreas (pancreatitis, trauma, infection, pancreatectomy, pancreatic CA). Endocrinopathies Drug- or chemical-induced diabetes Uncommon forms of immune-mediated diabetes (The Stiff-Man Sdr) Other genetic syndromes (chromosomal abnormalities of Down’s, Turner’s, Klinefelter’s Syndroms, autosomal recessive disorder Wolfram's Sdr, insulin-deficient diabetes) sometimes associated with diabetes
Is there a cure for DM? Type 1 DM: Artificial pancreas: CGM, Computer controlled algorithm, Insulin pump, patient effect Vaccine Type 2 DM: Understanding genetic mechanisms & diabetes pathobiology VLCD: Di. Re. CT study route to T 2 DM remission
Daniel Darkes, from Daventry, was diagnosed with Type 1 DM in 2010, but recent test results showed his blood sugar levels were below average, suggesting his pancreas may have started working. Speaking to The Daventry Express the 30 -year-old said: “The doctors aren’t sure really, it could be because I do a lot of running. They reckon a lot of vitamin C and D can also cause cells to be reproduced in the organs. I’ll get a better picture once I’m over in America. ”
