Diabetes Flashcards

All 7 cards in this deck

How is type 1 diabetes controlled?: By insulin injections, together with controlling carbohydrate/sugar in the diet and exercise.
State the cause of type 2 diabetes.: The body's cells have stopped responding to insulin (insulin resistance).
State two ways a person with type 2 diabetes can control their blood glucose concentration.: Reduce carbohydrate / sugar in their diet, lose weight, exercise more, or take medication (e.g. metformin or insulin).
What is the equation for BMI?: BMI = mass (kg) ÷ (height (m))²
How is a waist : hip ratio calculated, and what does a high value mean?: Waist measurement ÷ hip measurement. A high ratio means more fat is stored around the waist, which is linked to a higher risk of type 2 diabetes.
What correlation do data show between body mass and type 2 diabetes?: A positive correlation — as body mass (or BMI) increases, the risk of developing type 2 diabetes increases.
What is the cause of type 1 diabetes?: The pancreas produces little or no insulin, so blood glucose concentration can rise too high.
