What is pathophysiology of diabetes?
Pathophysiology of diabetes refers to the study of the disordered physiological processes that lead to the development of diabetes mellitus.
Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels that result from defects in insulin secretion, insulin action, or both.
The pathophysiology of diabetes involves the complex interplay of genetic, environmental, and lifestyle factors that contribute to the development of the disease.
In type 1 diabetes, the pathophysiology involves an autoimmune destruction of the insulin-producing beta cells in the pancreas, leading to a deficiency in insulin production.
This results in an inability to regulate blood glucose levels, leading to hyperglycemia (high blood sugar).
In type 2 diabetes, the pathophysiology is more complex and involves both insulin resistance and impaired insulin secretion.
Insulin resistance occurs when the body's cells do not respond properly to insulin, leading to an inability to effectively use glucose for energy.
This causes the pancreas to produce more insulin to try to overcome the resistance, but over time, the pancreas may not be able to keep up with the demand, leading to a decrease in insulin production.
Gestational diabetes, which occurs during pregnancy, is caused by hormonal changes that lead to insulin resistance.
The placenta produces hormones that can block the action of insulin, leading to an increase in blood glucose levels.
The pathophysiology of diabetes also involves the development of complications, such as damage to blood vessels, nerves, and organs, which can lead to serious health problems like heart disease, stroke, kidney disease, and vision loss.
Understanding the pathophysiology of diabetes is crucial for developing effective treatments and prevention strategies for this chronic disease.
