It’s highly likely that someone you’re acquainted with has type 2 diabetes. According to the National Institutes of Health (NIH), over 37 million people in the United States—approximately 1 out of every ten individuals—suffer from diabetes, with about 95% of cases—around 35 million people—being type 2 diabetes. This chronic condition hinders the body from utilizing insulin effectively, resulting in elevated blood glucose levels.
In recent times, the prevalence of type 2 diabetes has surged globally, partly due to escalating levels of obesity and sedentary lifestyles. Previously known as adult-onset diabetes because it typically affected adults, type 2 diabetes is now increasingly detected in children and young adults.
Fortunately, type 2 diabetes can be managed through lifestyle adjustments, monitoring blood glucose levels, and medications designed to lower blood glucose levels.
“In the last ten years alone, new classes of diabetes medications have emerged, completely transforming the treatment options available for diabetes,” remarks Dr. Anika Anam, an endocrinologist at Yale Medicine. “Additionally, there have been remarkable advancements in diabetes technology, ranging from continuous glucose monitors to ‘closed-loop’ insulin pumps, enhancing patients’ ability to manage their diabetes efficiently.”
In addition to elevated blood glucose levels, individuals with type 2 diabetes may experience symptoms such as frequent urination, increased thirst, unexplained weight loss, fatigue, blurred vision, and slow-healing wounds. Long-term complications of uncontrolled type 2 diabetes can include heart disease, stroke, kidney damage, nerve damage, and vision problems.
Management of type 2 diabetes typically involves a combination of lifestyle changes, such as healthy eating, regular exercise, and weight management, along with medication and monitoring blood glucose levels. It is essential for individuals with type 2 diabetes to work closely with healthcare professionals to develop a personalized treatment plan and reduce the risk of complications associated with the condition.

Genetics
Genetics play a significant role in the risk of type 2 diabetes, particularly in those with family members affected by the condition. Having a parent with diabetes increases the likelihood of a child developing the condition.
Being overweight or obese
Individuals who are overweight are more susceptible to type 2 diabetes, especially if they carry excess abdominal fat. This elevates the risk of serious conditions like heart disease and cancer. Monitoring waist circumference and achieving weight loss can diminish the risk of diabetes.
Ethnicity
Individuals of South Asian, Chinese, African-Caribbean, and Black African descent face a heightened risk of developing type 2 diabetes. These populations exhibit an increased susceptibility compared to the general populace, underlining the necessity of lifestyle management.
South Asian and African-Caribbean individuals have a greater risk of developing type 2 diabetes complications, like heart disease, at a younger age. The risk of type 2 diabetes increases with elevated blood glucose levels, also known as pre-diabetes. Implementing lifestyle changes, such as adopting a healthy diet and engaging in regular exercise, can prevent pre-diabetes from evolving into type 2 diabetes. Women with a history of gestational diabetes during pregnancy have a higher risk of developing diabetes later in life.
Type 2 diabetes is a progressive condition that typically worsens with time. While lifestyle changes can initially help manage blood glucose levels, medication may eventually be required. Metformin is frequently the first medication prescribed to reduce glucose release from the liver in type 2 diabetes. Additionally, there are other medications like SGLT2 inhibitors, GLP-1 agonists, sulphonylureas, pioglitazone, and gliptins that work in different ways to manage glucose levels.
If lifestyle changes and medications are not effective, insulin treatment may be necessary. Insulin needs to be injected due to stomach breakdown. It’s crucial to be mindful of hypoglycemia and know how to address it. Regular monitoring of blood glucose levels is essential.
To reduce the risk of developing other health conditions, additional medications may be recommended, such as anti-hypertensive drugs for high blood pressure and statins for cholesterol. Continuously monitoring blood glucose levels is vital in managing type 2 diabetes. It’s important to aim for a target HbA1c level under 53 mmol/mol (7%) and monitor glucose levels at home if advised.
It’s essential for individuals with diabetes to regularly monitor blood glucose levels due to various factors that can affect them. Using a blood glucose meter can help keep track of readings and identify any irregularities.
Your healthcare team can provide advice on using a blood glucose meter, interpreting results, setting individual targets, and effectively managing the condition.
Uncontrolled diabetes can lead to various complications, such as heart disease, nerve damage, eye issues, kidney problems, foot ulcers, and sexual dysfunction. Maintaining blood glucose within a healthy range is vital to reduce these risks.
Regular eye checks, foot care, and lifestyle adjustments can assist in preventing or managing diabetes-related complications. By taking proactive steps to control the condition, individuals can lead a healthier and more fulfilling life.
