Type 2 diabetes is a chronic disease that requires constant day-to-day care and management. It is a complex condition influenced by various factors, including genetics, age, race, diet, physical activity, weight, stress, alcohol intake, sleep, and smoking. Diagnosis of Type 2 diabetes involves assessing blood glucose levels and identifying classic symptoms. Blood tests such as the hemoglobin A1C criteria, fasting plasma glucose (FPG), and plasma glucose concentration are commonly used to measure blood glucose levels. According to the American Diabetes Association (ADA), an FPG level above 126 mg/dL or a plasma glucose level exceeding 200 mg/dL after a glucose tolerance test indicates a positive diagnosis. Additionally, exhibiting symptoms like increased thirst, frequent urination, slow wound healing, blurred vision, and unexpected weight loss further supports a diagnosis of Type 2 diabetes.

Prediabetes and risk factors
Prediabetes is a condition where your blood glucose levels are higher than normal but not high enough to be officially diagnosed with Type 2 diabetes. It is a key opportunity for prevention, as it can be treated or reversed through intensive lifestyle changes, such as calorie restriction and increased physical activity. Prediabetes is associated with an increased relative risk of all-cause mortality, cardiovascular disease, coronary heart disease, and stroke.
Major risk factors for prediabetes include overweight and obesity, older age (45 years and older), genetic predisposition, unhealthy diet, physical inactivity, socioeconomic deprivation, and having current or previous conditions, such as metabolic dysfunction-associated steatotic liver disease or gestational diabetes. Race and ethnicity also play a role, with Asian, Black, and Hispanic adults at higher risk than White adults. Additionally, if you have a family history of Type 2 diabetes, your risk increases to 40% if one parent has it and 70% if both parents do.
Gestational diabetes, which occurs during pregnancy, usually goes away after giving birth. However, having a history of gestational diabetes increases the risk of developing Type 2 diabetes later in life. Other risk factors for gestational diabetes include giving birth to a baby weighing over 9 pounds, being over 25 years old, having a hormone disorder called polycystic ovary syndrome (PCOS), and belonging to certain racial and ethnic minority groups.
While some risk factors like age, race, and family medical history cannot be changed, there are steps you can take to lower your risk of developing prediabetes and Type 2 diabetes. These include eating a healthy diet, such as the Mediterranean diet, getting regular physical activity, achieving a healthy weight, managing stress, limiting alcohol intake, getting adequate sleep, and quitting smoking. It is important to note that prediabetes can progress to Type 2 diabetes if left untreated, so early detection and treatment are crucial.

Diagnosis tests
Type 2 diabetes can be diagnosed through various tests, each of which usually needs to be repeated on a second day for confirmation. These tests should be carried out in a healthcare setting, such as a doctor's office or a lab. If your blood glucose (blood sugar) level is very high or if you have classic symptoms of high blood glucose in addition to one positive test, your doctor may not require a second test to diagnose diabetes.
Hemoglobin A1C (HbA1C) criteria
The A1C test measures your average blood glucose levels over the past two to three months. It is a convenient, rapid, and standardised test with less variation due to pre-analytical variables. It is not significantly affected by acute illness or stress. An HbA1C level of greater than 6.5% (48 mmol/mol) is indicative of diabetes. However, it is costly and has some limitations, such as lower sensitivity and potential inaccuracies in specific populations or health conditions.
Fasting Plasma Glucose (FPG)
For this test, a blood sample is taken after an 8-hour overnight fast. A fasting plasma glucose (FPG) level of more than 126 mg/dL (7.0 mmol/L) is consistent with a diagnosis of diabetes.
Oral Glucose Tolerance Test (OGTT)
In this test, the plasma glucose level is measured before and two hours after ingesting 75 grams of glucose. Diabetes is diagnosed if the plasma glucose (PG) level in the two-hour sample is more than 200 mg/dL (11.1 mmol/L). This test is more inconvenient and costly than FPG and has major variability issues. However, it provides an average of blood glucose levels over the last two to three months.
It is important to note that prediabetes is a stage before Type 2 diabetes, where blood glucose levels are higher than normal but not high enough for a Type 2 diabetes diagnosis. Early treatment of prediabetes can help return blood glucose levels to a normal range and significantly reduce the risk of developing Type 2 diabetes.

Symptoms
Type 2 diabetes occurs when the pancreas cannot produce enough insulin to maintain a normal blood glucose level, or when the body is unable to use the insulin that is produced (insulin resistance). This results in high blood glucose levels, a condition known as hyperglycaemia.
The symptoms of type 2 diabetes can take years to develop and are often mild, meaning many people may have the condition without realising it. In fact, some people with type 2 diabetes do not experience any symptoms at all. When symptoms are present, they may include:
- Extreme thirst and frequent urination (also known as polyuria)
- Blurry vision
- Fatigue
- Weakness
- Losing weight without trying
If left untreated, high glucose levels can damage blood vessels, nerves and organs, and increase the risk of heart disease and stroke. Therefore, early diagnosis and treatment for type 2 diabetes are very important to reduce the risk of developing complications later on.
There are several tests that can be used to diagnose type 2 diabetes, including the Hemoglobin A1C (HbA1C) test, the Fasting Plasma Glucose (FPG) test, and the Random Plasma Glucose (RPG) test. These tests measure the average blood glucose level over a certain period of time, with diabetes being diagnosed when the blood glucose levels reach a certain threshold.
