Diabetes Education Pathophysiology and Treatment

Question 1

What is the primary cause of Type 1 Diabetes?

Accepted Answer

Autoimmune destruction of beta cells

Answer

Type 1 Diabetes is an autoimmune condition where the body's immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. This destruction leads to an absolute deficiency of insulin, which is essential for glucose uptake by cells. Without insulin, glucose accumulates in the bloodstream, leading to high blood sugar levels.

Question 2

What is a common treatment for Type 2 Diabetes?

Accepted Answer

Oral medications such as metformin

Answer

While diet modification and exercise are fundamental, oral medications like metformin are a common first-line pharmacological treatment for Type 2 Diabetes. Metformin works by reducing glucose production by the liver and improving insulin sensitivity in the body's cells. Insulin injections are typically reserved for later stages or when oral medications are insufficient to control blood sugar.

Question 3

What is insulin resistance in Type 2 Diabetes?

Accepted Answer

The body's cells fail to respond to insulin

Answer

Insulin resistance is a hallmark of Type 2 Diabetes, where the body's cells (muscle, fat, and liver) do not respond effectively to insulin. This means glucose struggles to enter the cells, leading to higher blood glucose levels. The pancreas initially tries to compensate by producing more insulin, but eventually, it may not be able to keep up with the demand.

Question 4

Which of the following is a common complication of poorly controlled diabetes?

Accepted Answer

Peripheral neuropathy

Answer

Peripheral neuropathy is a common and serious complication of poorly controlled diabetes, resulting from nerve damage due to persistently high blood sugar levels over time. It often affects the feet and hands, causing numbness, tingling, pain, and weakness. Other complications include retinopathy, nephropathy, and cardiovascular disease.

Question 5

What role does the pancreas play in diabetes?

Accepted Answer

Answer

The pancreas plays a vital role in diabetes by producing hormones, primarily insulin and glucagon, which regulate blood sugar levels. Insulin lowers blood sugar by allowing glucose to enter cells, while glucagon raises it. In diabetes, either insulin production is insufficient (Type 1) or the body's cells are resistant to its effects (Type 2), leading to dysregulation of blood glucose.
