Final answer:
Insulin resistance is a condition characterized by the body's inability to effectively use insulin, particularly in type 2 diabetes, leading to elevated blood glucose levels and potential malnutrition due to cells being unable to absorb sufficient glucose.
Step-by-step explanation:
Understanding Insulin Resistance
When the body does not respond to insulin, the condition is known as insulin resistance. In the context of diabetes, particularly type 2 diabetes, insulin resistance occurs when cells in the body do not effectively use the insulin. While the pancreas is still producing insulin, the body's cells are unable to efficiently utilize it, leading to high blood sugar levels. This condition often develops with advancing age or due to factors such as obesity, and it significantly increases the risk of developing type 2 diabetes.
As insulin resistance worsens, the blood glucose levels remain elevated, creating a situation where the cells are "starving in a sea of plenty." Despite the abundant glucose in the bloodstream, the cells cannot absorb it for energy due to malfunctioning insulin receptors. Consequently, this can lead to symptoms of malnutrition because the cells are not receiving the glucose they need for vital functions.
Monitoring blood glucose levels is critical for managing diabetes. For patients with type 1 diabetes, which involves the destruction of insulin-producing cells, frequent blood glucose monitoring and insulin injections are necessary. For those with type 2 diabetes, lifestyle changes, medications, and in some cases, additional insulin may be incorporated into the treatment plan to help manage insulin resistance and high blood glucose levels.
