Insulin resistance is a condition where the body's cells become less sensitive to the hormone insulin. Insulin helps cells absorb glucose from the blood to use as energy. When cells resist insulin, it becomes harder for glucose to enter them, leading to higher blood sugar levels.
This condition is important for health because it can lead to prediabetes and type 2 diabetes if not managed. High blood sugar levels over time can cause damage to various organs and increase the risk of heart disease and other health problems.
In the body, insulin is produced by the pancreas. When you eat, insulin helps move sugar from the bloodstream into the cells, where it's used for energy. If the cells don't respond properly, the pancreas produces more insulin to try to get the cells to take in glucose, which can eventually wear out the pancreas.
If you notice symptoms like increased thirst, frequent urination, or unexplained fatigue, it might be helpful to learn more about insulin resistance. A healthcare provider can offer advice and testing if needed.
