Diabetes is characterized by elevated blood sugar levels.
Some common symptoms of type 2 diabetes include frequent urination, increased thirst, unexplained weight loss, fatigue, blurred vision, and slow healing of wounds. It is important to note that some individuals may not exhibit any symptoms at all.
Diagnosis of type 2 diabetes is typically done through blood tests that measure blood sugar levels. The most common test is the A1C test, which measures your average blood sugar levels over the past 2-3 months. Fasting blood sugar tests and oral glucose tolerance tests are also commonly used to diagnose diabetes.
Types of diabetes
While diabetes can be diagnosed in childhood, it can also occur at any age and is unavoidable. Certain factors like ethnicity, age, and weight may increase the risk. Lifestyle changes and treatment can help prevent diabetes. Pregnancy can also trigger diabetes, which typically resolves after delivery.

Causes of diabetes
Insulin-related issues leading to high blood sugar levels cause diabetes. Type 1 diabetes cannot be prevented, while factors like weight and genetics increase the likelihood of type 2 or gestational diabetes. Lifestyle changes can help reduce the risk.
Pre-diabetes (non-diabetic hyperglycaemia)
Pre-diabetes can progress to type 2 diabetes, but lifestyle changes can lower the risk. Those with pre-diabetes may qualify for the NHS Diabetes Prevention Programme.
Treatment for diabetes
Treatment for diabetes varies based on the type. Type 1 diabetes requires insulin and monitoring by specialists, while type 2 and gestational diabetes are managed through lifestyle modifications and medication.
Long-term complications of diabetes
Diabetes can lead to various complications such as heart issues and nerve damage. Maintaining proper blood sugar levels is crucial to minimize risks.
Symptoms of diabetes are similar in adults and children, with gradual development. Type 1 diabetes symptoms manifest quickly and are more common in younger individuals.
Who is more likely to get type 2 diabetes
Risk factors for type 2 diabetes include age, ethnicity, weight, and family history. Individuals at risk should undergo screening for early detection.
Other risk factors for type 2 diabetes include high blood pressure, low levels of physical activity, and a diet high in processed foods and sugar. Additionally, smoking and excessive alcohol consumption can increase the risk of developing type 2 diabetes.
It is important for individuals with risk factors to make healthy lifestyle choices, such as maintaining a healthy weight, exercising regularly, and eating a balanced diet, to reduce their risk of developing type 2 diabetes.
Non-urgent advice: See a GP if:
- Suspect type 2 diabetes
- At risk for type 2 diabetes
Not everyone with type 2 diabetes displays symptoms, emphasizing the importance of screening.
It is important to note that risk factors for type 2 diabetes include being overweight, having a sedentary lifestyle, and having a family history of the disease. Regular check-ups and screenings can help catch diabetes early and prevent complications. If you are concerned about your risk factors or suspect you may have diabetes, make an appointment with your GP for testing and further guidance.
