decreases blood glucose increases blood glucose

Stephen complains to his doctor of frequent urination and extreme thirst. Over the past 3 months, he also lost 12 pounds without dieting. His doctor sends him for tests to see if he has

diabetes.

Which of the following are traditional symptoms of diabetes?

Mel has diabetes and uses insulin for glucose management. If he takes more than his prescribed dose of insulin,

his blood sugar will be too low.

Choose risk factors for type 2 diabetes.

history of gestational diabetes physical inactivity family history of diabetes obesity, especially intra- abdominal obesity prediabetes

Fibers that are not readily dissolved in water and not easily metabolized by intestinal bacteria are called

insoluble fiber.

A high-fiber diet is helpful for weight management because

it provides few calories. it contributes to a feeling of fullness after eating.

Many patients with type 2 diabetes can improve blood glucose control by

losing a moderate amount of weight.
