Type 2 diabetes is a chronic condition in which blood sugar rises due to the body resisting insulin or not making enough of it. Early detection and regular follow-up help control it and reduce complications. This guide explains the symptoms, diagnosis and basics of control.
What is type 2 diabetes?
It is a chronic rise in blood glucose caused by cells responding poorly to insulin (insulin resistance) together with a relative drop in its secretion. It differs from type 1, which usually starts at a younger age and depends on insulin from the outset.
Early symptoms
Symptoms may be mild or unnoticed for a while, and the most common include:
- Frequent urination and excessive thirst.
- Frequent hunger and general fatigue.
- Blurred vision.
- Slow-healing wounds and repeated infections.
Risk factors
- Overweight or obesity, especially around the abdomen.
- Low physical activity and a sedentary lifestyle.
- A family history of diabetes.
- Older age, and high blood pressure or cholesterol.
How is diabetes diagnosed?
Diagnosis relies on blood tests requested by the doctor, including:
- Fasting blood glucose.
- HbA1c, which reflects the average blood sugar over recent months.
- A glucose tolerance test in some cases.
Control and lifestyle
Control rests on integrated pillars:
- A balanced diet with attention to the amount and type of carbohydrates.
- Regular physical activity that improves the body's response to insulin.
- Adherence to medication prescribed by the doctor when needed.
- Regular monitoring of blood sugar, blood pressure and lipids.

Frequently asked questions
What is the difference between type 1 and type 2 diabetes?
Type 1 results from the pancreas stopping insulin production and usually starts younger, while type 2 relates to insulin resistance and lifestyle factors and usually appears in adults.
Can type 2 diabetes be prevented?
In many cases the risk can be meaningfully reduced through a healthy weight, physical activity and balanced nutrition, especially for those with risk factors.
Which tests do I need?
Usually fasting blood glucose and HbA1c, and the doctor may add other tests based on your case. Requesting and interpreting them is done by the doctor.
Is type 2 diabetes curable?
It is usually described as a chronic condition that can be well controlled, and some patients reach excellent sugar control with lifestyle changes under medical supervision.
