What is Type 2 Diabetes?
Type 2 diabetes is a long-term health condition where your body cannot properly use insulin, which leads to high blood sugar levels.
In a healthy body, insulin helps move sugar (glucose) from the blood into the cells, where it is used for energy. But in type 2 diabetes, the body either resists insulin or doesn’t make enough of it.
Because of this, sugar stays in the bloodstream instead of being used. Over time, high blood sugar can affect important organs like the heart, kidneys, eyes, and nerves if not managed properly.
According to the Centers for Disease Control and Prevention, type 2 diabetes is one of the most common chronic conditions affecting millions of people worldwide.

Symptoms at a Glance
| Symptom | Description |
| Frequent urination | Passing urine more often than usual |
| Thirst | Feeling thirsty again and again |
| Fatigue | Feeling tired without reason |
| Blurred vision | Difficulty seeing clearly |
| Numbness | Tingling in hands or feet |

Causes of Type 2 Diabetes
There is no single reason for type 2 diabetes. It usually develops due to a combination of lifestyle and genetic factors. Research from the National Institute of Diabetes and Digestive and Kidney Diseases shows that insulin resistance and lifestyle factors play a major role in the development of type 2 diabetes.
Main Causes:
- Insulin resistance
- Family history (genetics)
- Being overweight
- Lack of physical activity
- Poor eating habits (high sugar, processed food)
Over time, the pancreas becomes tired and cannot produce enough insulin.
Risk Factors
| Risk Factor | Impact Level |
| Family history | High |
| Obesity | High |
| Physical inactivity | High |
| Poor diet | Moderate |
| Age (40+) | Moderate |

| HbA1c | Below 5.7% | 5.7–6.4% | 6.5%+ |
| Post-meal | Below 140 | 140–199 | 200+ |
Type 2 Diabetes vs Type 1 Diabetes
| Feature | Type 1 | Type 2 |
