  • Diabetes is a chronic condition that interferes with the way the body converts food into energy. There are three types of diabetes. 

  • People with an increased risk of developing type 2 diabetes include those who are overweight, those who have a family history of diabetes, those who are age 45 and older, those who have prediabetes, etc.

  • Type 2 diabetes is preventable through lifestyle changes such as losing weight, improving one’s diet, and exercising more.

Diabetes is a metabolic disorder that affects the way the body converts food into energy. There are three types of diabetes: type 1, type 2, and gestational. While type 1 diabetes is an autoimmune disorder, type 2 diabetes can be prevented by making necessary lifestyle adjustments. 

This article will focus on how to prevent type 2 diabetes.

What Is Diabetes?

Diabetes is a chronic condition that impacts the way the body converts food into energy. There are three main types of diabetes: 

  • Type 1 Diabetes: Type 1 diabetes is an autoimmune condition that stops the body from creating insulin. It’s most often diagnosed during childhood, teenage years, or early adulthood. Currently, no research shows how to prevent this particular type of diabetes. 

  • Type 2 Diabetes: Type 2 diabetes occurs when the body cannot use insulin in the way it is meant to be used and blood sugar becomes unstable as a result. Type 2 diabetes develops over many years.

  • Gestational Diabetes: Gestational diabetes occurs during pregnancy in those who have not been diagnosed with diabetes before becoming pregnant. Gestational diabetes usually resolves once the baby is born. However, getting gestational diabetes increases one’s risk of developing type 2 diabetes later on in life.

Type 2 Diabetes Symptoms

Symptoms of type 2 diabetes include: 

  • Frequent urination (especially at night) 

  • Weight loss without trying

  • Intense hunger and thirst

  • Blurry vision

  • Fatigue

  • Very dry skin

  • Slow-healing sores

  • More infections than normal

Note: If experiencing any signs or symptoms of type 2 diabetes, it’s incredibly important to get a blood sugar test and get diagnosed. 

Type 2 Diabetes Risk Factors

Several risk factors make someone more susceptible to developing type 2 diabetes including: 

About Prediabetes

Prediabetes is a serious health condition marked by high blood sugar (blood glucose) levels. While this higher blood sugar is not within the normal range, it is still not high enough for someone to receive a diabetes diagnosis. That said, those with prediabetes are at an increased risk of developing type 2 diabetes along with heart disease and stroke.

Thankfully, lifestyle changes can be taken to prevent or delay diabetes as well as other health problems. If someone is at risk for prediabetes, they can take a simple blood sugar test to see. If they are diagnosed, they can then make the necessary lifestyle adjustments from there.

Note: This tool from the Centers for Disease Control and Prevention can test one’s risk for having prediabetes. Check it out here.

Diabetes Prevention: Tips

Making necessary lifestyle changes is the best way to prevent type 2 diabetes from developing. The National Institute Of Diabetes and Digestive and Kidney Diseases focuses on diet, movement, and healthy eating as key ways to delay the development of type 2 diabetes. There are other strategies, such as monitoring alcohol consumption, that can be implemented as well. All of these lifestyle shifts are discussed in more detail below.

Lose Weight

Maintaining a healthy weight is important for diabetes prevention. A healthy body weight is considered to have a body mass index (BMI) between 18.5 to 24.9. Use this BMI calculator to calculate your own and find out your optimal weight range.

Healthy Eating

Incorporating more healthy foods into one’s diet along with avoiding unhealthy choices can make a huge difference in one’s overall health and wellness. Some tips for healthier eating include: 

  • Eat smaller portions: Eating appropriate quantities of food can help promote weight loss while eating too much food can lead to weight gain. How much someone should consume depends on a variety of factors including one’s age, current weight and height, gender, metabolism, and how much physical activity one gets. Learn more about portion sizes at this resource.
  • Swap sugar-sweetened drinks for water: Sweetened beverages include sodas, sports drinks, and juices. Drinking water can help cut calories and keep one feeling hydrated and fuller longer.
  • Skip unhealthy food choices as much as possible: These include fatty foods, heavily processed foods, foods with high sugar content, etc.
  • Choose healthy options as much as possible: This includes healthy fats, whole grains over refined carbohydrates, and plenty of fruits and vegetables.

Exercise Regularly

Becoming more physically active is highly beneficial for many reasons but a major one is lowering the risk of type 2 diabetes. Physical activity to incorporate into one’s routine includes both aerobic exercise and strength training exercises. Some examples of exercises to consider include: 

  • Walking
  • Jogging/​running
  • Pilates
  • Yoga
  • Weight lifting

Quit Smoking

Quitting smoking helps lower one’s diabetes risk. Smokers are 50 percent more likely to develop diabetes than nonsmokers. As well, smoking can lead to insulin resistance, which can then lead to type 2 diabetes. Insulin resistance is when cells stop responding to insulin and blood sugar levels become out of whack.

Talk To Your Healthcare Provider

Your healthcare provider may be able to offer additional tips or information to help with diabetes prevention, including taking certain diabetes medications if you’re at high risk.
