        Diabetes
        Epidemiology
        The number of people with diabetes has risen from 108 million in 1980 to 422 million in 2014.
        Rate of diagnosed diabetes is 15.1% of American Indians/Alaskan Natives
        in 2017, 17.3% of the UAE population between the ages of 20 and 79 have type 2 diabetes.
        There are over 1 million people living with diabetes in the UAE
        the country 15th worldwide for age-adjusted comparative prevalence.

        Indications
        Type 1 diabetes that can't be controlled with standard treatment
        Frequent insulin reactions
        Consistently poor blood sugar control
        Severe kidney damage
        Type 2 diabetes associated with both low insulin resistance and low insulin production
        Complications
        Blood clots\ Bleeding\ Infection\ hyperglycemia\ Urinary complications, including leaking or urinary tract infections\ Failure of the donated pancreas\ Rejection of the donated pancreas
        Management of HTN in diabetes
        Complications
        Diabetic Ketoacidosis
        Free fatty acids released in the periphery are bound to albumin and transported to the liver, converted to ketone bodies.
        The primary ketone bodies β-hydroxybutyrate (βHB) and acetoacetic acid (AcAc) account for the metabolic acidosis seen in DKA. AcAc is metabolized to acetone, another major ketone body.
        Increased ketogenesis. Low insulin levels decrease the ability of the brain and cardiac and skeletal muscle to use ketones as an energy source, increasing ketonemia.
        Hyperglycemia will cause osmotic diuresis resulting in volume depletion.
        As adipose tissue is broken down, prostaglandins I2 and E2 are produced. Both account for the paradoxical vasodilation that occurs despite profound levels of volume depletion.
        High concentrations of ketones can make the urine acidic and cause fruity-smelling breath
        If not managed, this condition can progress to coma (prolonged unconsciousness) and even death.
