Diabetes affects how the body regulates glucose in the blood. Type 2 diabetes is the most common form and may develop gradually, sometimes with mild symptoms that go unnoticed for years.
Possible symptoms deserve attention
Symptoms can include unusual thirst, frequent urination, tiredness, blurred vision, or unintentional weight loss. These symptoms can have many causes, so diagnosis requires appropriate blood testing and clinical assessment rather than self-diagnosis.
Know the factors that may increase risk
Risk can be influenced by family history, age, body weight, physical activity, previous gestational diabetes, and other health conditions. A clinician can review these factors and advise whether screening is appropriate even when you feel well.
Practical steps that support prevention
- Choose a balanced diet with suitable portions and fewer highly processed foods.
- Build regular physical activity into the week at a level appropriate for your health.
- Work toward a healthy body weight with professional support when needed.
- Avoid tobacco use.
- Attend recommended checkups and blood tests.
Early diagnosis supports better care
Untreated high blood glucose can damage blood vessels and affect the heart, eyes, kidneys, nerves, and feet. Early diagnosis allows a doctor to create a plan that may include nutrition, physical activity, monitoring, medicine, and screening for complications.
If you already have diabetes
Keep regular appointments and take medicine as prescribed. Ask how often you need blood-glucose monitoring, kidney tests, eye examinations, and foot checks. Contact your care team if you are struggling with treatment or experiencing new symptoms.
Individual screening and treatment decisions should always be made with a qualified healthcare professional.
