Question 1

Shortly after eating a bowl of cream of mushroom soup you experience intestinal gas, bloating, and diarrhea. Your friend also ate the soup and appears to be fine. What is the most likely cause of your symptoms?

Accepted Answer

Lactose intolerance is the most likely cause because it leads to difficulty digesting lactose found in dairy products like cream, causing symptoms such as gas, bloating, and diarrhea. The fact that your friend is fine suggests it's not food poisoning, and the symptoms don't align with a milk allergy or hypoglycemia.

Sarah's doctor wants to screen her for reactive hypoglycemia. If her doctor's suspicions are correct and Sarah does have reactive hypoglycemia, what would you expect her blood glucose concentration to be at approximately TWO HOURS after she had begun her glucose tolerance test?

Accepted Answer

Reactive hypoglycemia is characterized by a drop in blood sugar levels following a meal. In a glucose tolerance test, a person with reactive hypoglycemia would show a lower blood glucose concentration about two hours after consuming glucose, as their body may release too much insulin in response to the glucose intake, leading to a decrease in blood glucose levels.

Question 19

Aakesh's doctor wants to screen him for type 1 diabetes. If his doctor's suspicions are correct and Aakesh's does have type 1 diabetes, what would you expect his blood glucose concentration to be at approximately TWO HOURS after he had begun his glucose tolerance test?

Accepted Answer

In individuals with type 1 diabetes, the pancreas produces little to no insulin, which is necessary for glucose to enter cells and be used for energy. Therefore, after consuming glucose in a glucose tolerance test, a person with type 1 diabetes would have an elevated blood glucose concentration compared to a normal individual, as their body cannot effectively utilize the glucose without adequate insulin.

Question 20

In type 1 diabetes, the ________ may be destroyed by an autoimmune disease.

Accepted Answer

In type 1 diabetes, the immune system mistakenly attacks and destroys the beta cells of the pancreas, which are responsible for producing insulin. This leads to an inability to regulate blood glucose levels properly.
