Tanya received some unsettling news at a recent checkup with her doctor. It had been a while since she had a physical examination, and some recent changes in her body prompted her to check in with her doctor. It seemed like she felt thirsty all the time, and her vision didn't seem as clear as it was earlier in life. The problems were relatively minor, but as a 50-year old woman who was admittedly a little out of shape, Tanya felt it was worth seeing the doctor.

Tanya's doctor asked her to come in early in the morning and without eating anything for breakfast. She said that was important for some blood tests they'd do. The doctor did a full examination, including blood tests, and told Tanya she was showing signs of diabetes mellitus. The doctor said this is unfortunately a very common disease in the United States, and though Tanya might not be experiencing major symptoms now, they needed to take steps to treat the problem. She said Tanya has lots of sugar in her blood, but her cells are starved for sugar. This is bad, she said, because we don't want our cells to be starved of the sugar they need to harness energy. The doctor said she would work with Tanya to modify her diet and start her on a reasonable exercise program. She said there also might be some medications to consider if diet and exercise don't do enough to correct the problem.

Which of the following is the best evidence that Tanya has Type 2 (not Type 1) diabetes mellitus?

-She is 50-years old and out of shape
-She feels thirsty all the time
-She has lots of sugar in her blood, but her cells are starved for sugar
-She is experiencing vision problems

Why are Tanya's cells starved for sugar (glucose) if there is so much glucose in the blood?

-Tanya ate too much glucose and the high levels have poisoned her cells
-Tanya's pancreas is not making insulin
-Tanya's cells don't recognize the messages telling them to let the glucose inside
-Tanya's cells are insensitive to the glucagon produced by her pancreas
