The “Diabetes” from Greek word meaning ‘a siphon’ is described as to pass through and because excessive urine is one of the sign. And “mellitus” from Latin and Greek meaning ‘honey or sweet’ because excess sugars (glucose) are found in blood as well as the urine of a person with diabetes Rudy bilious And Richard Donnelly (2010). The taste of urine as a sweet like honey has been proved by a physician in 1967 as they tasted the urine of diabetic person Dr Ananya Mandal (2013). Globally estimation of 70 000 children are likely to develop diabetes each year which amounts to 200 new cases per day (Helen Thornton, 2009).

Diabetes Mellitus is very common chronic disease and this condition has been increasing Rudy bilious And Richard Donnelly (2010). According to data from Diabetes Atlas (2009), age adjusted prevalence in the 20-79 year age group in worldwide there will be rise from 5.9% to 7.1% (246-380 millions).   The reason for this metabolic disorder is because of lack or reduced effectiveness of endogenous insulin which is characterised by persistent hyperglycaemia affecting the vasculature (Hayley Willacy 2013). There are two types of diabetes: Type 1 and Type 2.  

Type 1 diabetes is also referred as an insulin-dependent diabetes mellitus. This is caused by the combination of genetic predisposition and autoimmune destruction of the insulin producing beta cells of the islets of Langerhans in the pancreas Richard IG Holt and Neil A Hanley (2007). The person with this type of diabetes requires injecting insulin to carefully monitor blood glucose level.
On the other hand Type 2 Diabetes is referred as a non –insulin dependent and is a result of both impaired insulin secretion and resistance to its action Rudy bilious And Richard Donnelly (2010). This type of diabetes is linked with excess body weight (obesity) and physical inactivity.
