- Discuss the differences between type 1 and type 2 diabetes and explain the reasons for the sign/symptoms seen in diabetes. ANSWER SHOULD INCLUDE: Type 1 - causes ,incidence Type 2 - cause, incidence Lack of insulin to blood glucose levels rise ( hyperglycaemia e.g. 20mmol/or more); glucose can not move into cells to provide energy for metabolic reactions. Link to symptoms, e.g. tiredness, hunger. Glucose excreted in urine ( exceeds renal threshold). Link to polyuria,thirst,dehydration - protein broken down to form more glucose (gluconeogenesis): provides energy to cells. -Link Fats broken down to FFA and glycerol for glucose production (gluconeogenesis). Link to weight loss. Link excess ketone bodies formed from fat break down to ketoacidosis. Link to ketone in urine (ketonuria), vomiting, coma.arrow_forwardCompare and contrast formulation of long acting insulin and short acting insulin.
