How To Prevent Type 2 Diabetes 

How To Prevent Diabetes Complications


The numbers are staggering: One in 12 Americans has diabetes—that’s over 25 million people in the US. Another 79 million are at high risk of developing type 2 diabetes. And many people don’t know that they have it or are at risk. Because of complications from uncontrolled diabetes, such as blindness, nerve damage and kidney disease, it’s also a leading cause of disability and death. That’s why it’s so important to be aware of diabetes, get tested for it at annual wellness visits (or sooner if you experience any symptoms) and practice prevention through healthy lifestyle habits.


What Is Type 2 Diabetes?       

Type 2 diabetes is a long-term condition that affects the way your body metabolizes sugar, a key source of fuel typically found in carbohydrates. With type 2 diabetes, your body either doesn’t use insulin effectively (called insulin resistance) or your pancreas, which secretes insulin into your bloodstream, doesn’t produce enough of it to maintain a healthy blood sugar level. Insulin is a hormone, and it’s needed to regulate the movement of sugar into your cells. Without it, high levels of sugar build up in your blood. (People with type 1 diabetes are unable to produce any insulin.)

As blood sugar levels increase, the insulin-producing cells in the pancreas try to pump out more insulin, but over time these cells become damaged and can’t make enough to meet demand.

Know Diabetes Risk Factors                         

Exactly why this happens to some people and not others isn’t clearly understood, but it’s known that certain factors increase the risk, including:

Being overweight. There’s a connection between fatty tissue and insulin resistance.

Belly fat. If you carry fat in your abdomen rather than your hips and thighs, your risk of type 2 diabetes is greater.

Inactivity. The more sedentary you are, the greater your risk.

Family history. Your risk of developing type 2 diabetes is higher if a parent or sibling has it.

Race. People of certain races, including blacks, Hispanics, American Indians and Asian-Americans, are more likely to develop type 2 diabetes than others.

Age. The risk of type 2 diabetes increases as you get older, especially after 45. But type 2 diabetes is also rising among young adults and even kids because of obesity and not enough exercise.

Know Diabetes Symptoms

Sometimes diabetes symptoms are so mild that they go unnoticed, but you may experience these signs:

  • You urinate often.
  • You’re often very thirsty.
  • You’re often very hungry even though you’re eating.
  • You’re extremely fatigued.
  • You have blurry vision.
  • You notice that cuts or bruises are slow to heal.
  • You feel tingling, pain or numbness in your hands or feet. 

If you experience any of these signs, talk to your doctor about having a blood test to check your blood sugar levels. 


How To Prevent Type 2 Diabetes

Diabetes-prevention550Healthy lifestyle choices can help you stave off type 2 diabetes. Even people at high risk can cut that risk in half through better lifestyle choices like healthier eating, getting more activity and losing weight. If you’ve been told that you have pre-diabetes, these lifestyle changes can slow or halt the progression of diabetes. The same changes can also lower the chances of developing heart disease and some cancers, so they have total wellness benefits, too.

According to data from the landmark Nurses’ Health Study I & II, healthy lifestyle habits can significantly counter even strong genetic risks for type 2 diabetes: Women least likely to develop diabetes are at a healthy weight with a body mass index under 25, eat a healthy diet, exercise for 30 minutes or more every day, don’t smoke and have about three alcoholic drinks per week. Data from the Health Professionals Follow-up Study, which looked at men, showed that men, too, can benefit from the same healthy lifestyle choices. Here’s how.

Lose WeightControl Your Weight.
Excess weight is the single most important cause of type 2 diabetes. Being overweight increases your chances of developing type 2 diabetes seven times, and being obese increases it by up to 40 times more than people at a healthy weight.  Losing just 7 to 10 percent of your current weight can cut your chances of developing type 2 diabetes in half. For more on losing weight, go to 

Eat Healthy

Eat Healthier Foods.
Diet isn’t only about less calories, it’s also about eating the foods that offer the best nutrition. In general, you want to choose foods that are lower in fat and calories and higher in fiber by focusing on fruits, vegetables and whole grains. Research into diabetes prevention found that these four key diet changes had the greater effect on lowering diabetes risk:

Replace refined carbohydrates with whole grains. Processed carbs include regular pasta, white rice, white bread, typical breakfast cereals and foods made with white flour, which is refined. Refining takes out the healthful bran and fiber from the grain.

Instead, aim for three servings a day of whole grains like whole-wheat pasta, brown or wild rice, whole grains like barley and quinoa, whole wheat and whole grain breads, whole grain breakfast cereals like bran flakes and oats and other foods made from whole grains. Whole grains aren’t as easily converted to sugar as refined grains, so you experience a lower, slower increase in blood sugar.

Replace sugary drinks with water, coffee, or tea instead. Sugar is a refined carbohydrate, too. The Nurses Health Study found that even one sugar-sweetened beverage a day could raise the risk of type 2 diabetes by 80 percent compared to women who drank less than one such drink a month. It’s important to know that even healthy sounding drinks, like 100-percent fruit juice, can be nearly as dangerous because of their high sugar content. Sugar can add to diabetes risk indirectly—by causing weight gain—and directly by increasing diabetes risk factors like chronic inflammation, high blood fats called triglycerides and lowered HDL cholesterol (the good type of cholesterol).

Water is the number one beverage—no fat, sugar or calories. But it’s okay to drink coffee and tea, both caffeinated and decaf, as long as you don’t add cream and sugar.

Replace saturated fats with healthier fats. The two types of dangerous fats are saturated fat found in animal foods from butter to beef (that white marbling is pure fat), and trans fat, found in many fast-food restaurant foods, packaged foods including those with “partially hydrogenated vegetable oil” in the ingredients list (it preserves their shelf life) and solid fats like some margarines. Instead choose poly- and mono-unsaturated fats found in liquid oils as well as in nuts and seeds. 

Replace unhealthy protein with good-for-you sources. Research shows that eating even a small 3-ounce serving of red meat—beef, pork, lamb—every day raises diabetes risk, and the risk from processed meat like bacon, hot dogs and cold cuts is even greater. Healthy protein sources include fish, skinless chicken, nuts, no- and low-fat dairy, poultry, and beans. For more ideas on healthy food choices, go to 


Increase Your Activity Level. 
A sedentary lifestyle is another serious risk factor for diabetes, whereas working your muscles (exercising) boosts their ability to use insulin and absorb glucose. Aim for 30 minutes of moderate physical activity like brisk walking, every day. If you can’t fit in one long workout, do three 10-minute sessions throughout the day, like before each meal (this may help reduce your appetite, too).

Studies have found a notable link between watching TV and developing diabetes. This could be because people tend to eat mindlessly while they watch and are already overweight and inactive. Try limiting viewing time and, when you do watch, march in place or do weight-resistance exercise during the commercials. For ideas on exercise, go to

Stop Smoking

Quit Smoking. 
Lung cancer and other lung diseases aren’t the only risks from smoking. Smokers are nearly twice as likely to develop diabetes than non-smokers, and if you’re a heavy smoker, your risk is even greater. Quitting requires a commitment. Find ways to make it easier at
