Type 2 diabetes condition guide: symptoms, causes, prevention, and when to seek care. Educational only — not a diagnosis.
Overview
Type 2 diabetes develops when the body does not use insulin well or does not make enough. Persistently high blood sugar can damage blood vessels, kidneys, eyes, and nerves. It is most often seen in adults but can also affect younger people.
Symptoms
- Excessive thirst
- Frequent urination
- Fatigue
- Blurred vision
- Slow-healing sores
- Unintentional weight loss
- Tingling in hands or feet
Causes
Contributing factors include excess body weight, low physical activity, family history, age, and diets high in sugar and unhealthy fats. Some people remain at risk even without obvious overweight.
Treatment (general information)
Care combines diet changes, activity, glucose monitoring, and medicines or insulin when needed. A clinic or doctor sets the plan. Do not change medicines without professional advice.
Prevention
Keep a healthy weight, walk or exercise regularly, cut sugary drinks, and get blood-sugar checks if you have family history or symptoms.
When to see a doctor
Seek care for extreme thirst, frequent urination, confusion, or a measured blood sugar that is very high or very low.
