Diabetes There Are Two Types of Diabetes: Type 1 and Type

Diabetes
There are two types of diabetes: Type 1 and Type 2. Both types of diabetes can cause a variety of serious health risks if left untreated. Some of these health problems include kidney disease, blindness, heart disease, and strokes.
About 5-10% of people with diabetes have Type 1 diabetes. Type 1 diabetes most commonly develops in young people. In Type 1 diabetes, the immune system destroys the cells in the pancreas that secrete insulin. Without insulin, the body's cells cannot absorb glucose, and thus cannot produce energy. Symptoms appear after about 90% of the cells have been destroyed. Although most cases of Type 1 diabetes are genetic, some have arisen in people who have had viral infections of the pancreas.
Most people who have diabetes (90-95%) have type 2 diabetes, which most commonly develops in people over age 40. Type 2 diabetes results from the inability of tissues to respond to insulin-a condition called insulin resistance. As Type 2 diabetes progresses, the pancreas produces less and less insulin, resulting in a condition called insulin deficiency.
There is no cure for either Type 1 or Type 2 diabetes. However, there are ways to manage both types. For Type 1 diabetes, treatment requires receiving regular insulin injections. Type 2 diabetes can also be treated with insulin injections, but can be also be managed with lifestyle changes, such as weight loss, exercise, and reducing intake of carbohydrates.
What is the best summary for the passage?

A) There are two types of diabetes that can pose serious health problems for people. It is important to know the risks and symptoms of diabetes.
B) Both types of diabetes affect people differently and cause health risks if left untreated. Fortunately, there are treatment options available to manage both types.
C) There is no cure for diabetes, but insulin injections can help maintain the condition.
D) Although most people have type 2 diabetes, type 1 diabetes can develop more commonly in young people.
