Why insulin is used?

Here are the primary reasons why insulin is used in medicine:

1. Diabetes Treatment:

Insulin is primarily used to manage type 1 and type 2 diabetes. In type 1 diabetes, the pancreas produces little or no insulin, while in type 2 diabetes, the body may not effectively utilize the insulin it produces. Insulin injections help replace or supplement the body's natural insulin and lower blood glucose levels.

2. Diabetic Emergencies:

Insulin is crucial in managing diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS). These are life-threatening conditions that can occur in people with poorly controlled diabetes. Insulin is used to correct extremely high blood sugar levels and restore balance.

3. Gestational Diabetes:

Gestational diabetes occurs during pregnancy and affects both the mother and the fetus. Insulin may be prescribed to manage blood glucose levels in women with gestational diabetes to ensure the well-being of both the mother and the baby.

4. Hyperglycemia Control in Non-Diabetic Patients:

In certain situations, non-diabetic patients may also require insulin. For example, severely ill individuals, critically ill patients, or those undergoing specific medical procedures may benefit from insulin to maintain blood glucose within normal ranges.

5. Research and Clinical Trials:

Insulin is routinely used in medical research and clinical trials. It is essential for studying the effects of different treatments and interventions on insulin resistance, glucose metabolism, and overall diabetes management.

These are the main medical applications of insulin. It remains a vital medication that helps millions of people with diabetes manage their blood sugar levels and prevent serious complications. As research continues to advance, new uses and applications for insulin may be discovered in the future.
