Type 2 diabetes (T2D) is a metabolic disorder characterized by insulin resistance and progressive beta cell dysfunction. It is mainly caused by lifestyle factors, such as poor diet, obesity, and physical inactivity, although a genetic predisposition also plays a role. T2D has become a global epidemic and is closely linked to cardiovascular disease, cancer, and neurodegenerative disorders.
Modifiable lifestyle factors significantly influence the development of T2D.
High consumption of refined carbohydrates and sugary foods worsens insulin resistance.
Excess fat, especially visceral fat, increases insulin resistance and inflammation.
Sedentary lifestyles reduce the absorption of glucose by muscles, worsening insulin resistance.
Poor sleep quality contributes to metabolic dysfunction and high levels of cortisol.
Symptoms often develop gradually, making early detection difficult.
Excess glucose passes into the urine, taking water with it.
Caused by high levels of glucose in the blood.
Due to the breakdown of fat and muscle to produce energy.
The result of the body's inability to use glucose as an energy source.
High glucose levels affect the balance of eye fluids.
An accurate diagnosis is based on blood sugar tests and the identification of the first signs of insulin resistance.

Management involves lifestyle changes, medication, and regular monitoring.
