• Why does steroids increase blood sugar?How can I control my blood sugar while on steroids?

  Steroids, specifically glucocorticoids, are a class of medications commonly prescribed for various medical conditions. One known side effect of these medications is their potential to increase blood sugar levels. Several mechanisms contribute to this effect, which can be explained as follows: 1. Increased Glucose Production: Glucocorticoids stimulate the liver to produce more glucose through a process called gluconeogenesis. Glucose is synthesized from non-carbohydrate sources, such as amino acids and fats, leading to elevated blood sugar levels. This increased glucose production contributes to the rise in blood sugar seen with steroid use. 2. Reduced Insulin Sensitivity: Steroids can cause insulin resistance, meaning that the body's cells become less responsive to the effects of insulin. Insulin is a hormone that helps regulate blood sugar levels by facilitating the uptake of glucose from the bloodstream into cells for energy. When cells are less sensitive to insulin, it results in reduced glucose uptake and higher blood sugar levels. 3. Impaired Insulin Secretion: Glucocorticoids can also affect the function of the pancreas, which is responsible for producing insulin. Steroids can impair insulin secretion from the pancreatic beta cells, leading to insufficient insulin levels for proper blood sugar regulation. The combination of reduced insulin sensitivity and impaired insulin secretion further contributes to hyperglycemia. 4. Altered Carbohydrate Metabolism: Steroids can disrupt the balance between carbohydrate metabolism and utilization in the body. They promote the breakdown of proteins and fats for energy while reducing the uptake and utilization of glucose by cells. This shift in metabolism favors higher blood sugar levels. 5. Redistribution of Fat: Steroid use can result in fat redistribution, with increased fat accumulation in certain areas of the body, such as the abdomen and face. This pattern of fat distribution, known as central or visceral obesity, is associated with insulin resistance and an increased risk of developing high blood sugar levels. 6. Duration and Dosage: The likelihood of experiencing increased blood sugar levels with steroid use can depend on the duration and dosage of the medication. Higher doses and longer durations of steroid treatment are generally associated with a greater risk of developing steroid-induced hyperglycemia. It's important to note that the impact on blood sugar levels can vary among individuals. Some people may be more susceptible to the effects of steroids on blood sugar regulation, particularly those with pre-existing diabetes or impaired glucose tolerance. Close monitoring of blood sugar levels is essential for individuals on steroids, especially those at risk of hyperglycemia.
