Final answer:
Type 2 diabetes is characterized by insulin resistance, resulting in high blood glucose levels. This leads to malnutrition as the cells are unable to utilize glucose effectively, causing the body to resort to alternative energy sources and potentially leading to weight loss and muscle wasting.
Step-by-step explanation:
In type 2 diabetes, insulin is produced but is nonfunctional. This means that even though insulin is present in the body, it doesn't effectively lower blood glucose levels. As a result, glucose cannot enter the cells to be used as an energy source, leading to a condition known as insulin resistance. In this state, the body's cells are unable to utilize the glucose available in the bloodstream, resulting in high blood glucose levels.
This inability to transport glucose into cells can cause malnutrition because the cells are deprived of the essential energy source they need to function properly. Without glucose entering the cells, the body may start breaking down alternative energy sources, such as fat and protein, which can lead to weight loss and muscle wasting. Over time, this can contribute to malnutrition and other complications.
