  • Type 2 diabetes
    • Non insulin dependant
      • Glycoprotein receptors on the body cell looses its responsiveness by insulin. The pancreas does secrete insulin
        • Liver and other target cells do not respond to insulin adequently
          • Can cause HYPOGLYCAEMIA  where excess inslin is stored as glycogen
            • Glycoprotein receptors on the body cell looses its responsiveness by insulin. The pancreas does secrete insulin
              • Liver and other target cells do not respond to insulin adequently
                • Can cause HYPOGLYCAEMIA  where excess inslin is stored as glycogen
    • No insulin injectiosn needed since there is normal glucose production
      • BMI ABOVE 27/excessive body fat/hgih body weight
        • Type 2 diabetes
          • Non insulin dependant
          • Environmental factors could bring an early onset of diabetes
          • Caued risks: living a sedetory lifesytle/l
          • Lack of exercise
          • High fat/carbohydrate diet
        • Responsiveness of insulin declines/degenerates, causing specificreceptors of the surface of the liver/muscle to decline
          • Cells decline and the cell looses the ability to respond to the insulin inn the blood
        • Genetic link: In 2000 sientists founf the contributory gene, which lies in chromosome 2
          • Early onset of type 2
            • obesity (30+BMI/poor diet/sedetory lifestyle)
              • Diet
                • Early onset of type 2
                  • obesity (30+BMI/poor diet/sedetory lifestyle)
                    • Diet
          • Ethnicity: South asians/black affrican carribean
