Now, the good news: It’s also one of the most preventable, and can be managed effectively with the right care.
Diabetes affects more than 34 million Americans — about 10 percent of the population. Most of those cases are type 2, and it’s a condition that usually affects older people.
But not always. More and more young people, teenagers, and even children in the United States are being diagnosed as prediabetic or type 2 diabetic.
We’ve put together this helpful guide to answer some of the most common questions about type 2 diabetes.
To understand type 2 diabetes, it’s helpful to understand how your body creates energy.
Most of the food you eat contains some sort of sugar (natural or added sugar), also called glucose. Once it’s absorbed into your body, your pancreas secretes a hormone called insulin. Insulin essentially acts like a doorman for your blood cells: it “unlocks” the cells so the glucose can get in, at which point your body converts it into energy. When you add more sugar to your diet, your pancreas secretes more insulin.
Sometimes, people who consume high levels of sugar — consistently, over time — develop insulin resistance. The amount of sugar in their bodies becomes greater than their pancreas’ ability to produce insulin, and their blood sugar rises as a result.
This is what can lead to prediabetes and type 2 diabetes.
If your blood sugar is higher than what’s considered normal but not yet high enough to be type 2 diabetes, it’s defined as prediabetes.
Most people who have type 1 diabetes are born with it but it may develop later in life. Type 1 diabetes is an autoimmune condition that causes people’s bodies to stop making insulin entirely.
It’s not entirely clear why type 1 diabetes happens, and unlike type 2, it’s not preventable.
Pregnant women sometimes develop gestational diabetes. This happens when the placenta secretes a hormone that makes insulin less effective. Blood sugar builds up in the bloodstream as a result.
It’s not clear why gestational diabetes happens. Less than 10 percent of pregnant women in the U.S. experience it, and it usually goes away after birth.
When blood glucose levels are above normal levels over a long period of time, as they are in people with diabetes, serious and life-threatening complications can occur:
These are just a few of the possible complications, and they can lead to other related problems. Studies have found that people with diabetes may be more likely to develop other medical conditions such as depression or Alzheimer’s disease.
As we outlined above, type 2 diabetes happens when the amount of sugar in someone’s body is greater than the amount of insulin they can produce.
Exactly how that happens can depend on several things. Some of the risk factors associated with type 2 diabetes include:
Certain ethnic groups are also at greater risk to develop type 2 diabetes, including Black Americans, Latina/o Americans, Native Americans, and Alaska Natives, as well as some Pacific Islanders and Asian Americans.
A lot of people don’t experience any symptoms of diabetes. That’s one reason why it’s important to have regular check-ups with your doctor.
That said, there are some symptoms that may lead a doctor to want to investigate further:
The only way to confirm type 2 diabetes is with a blood test.
There are a few different tests that a doctor may use:
Fasting plasma glucose test — Taken after an eight-hour fast.
Random plasma glucose test — Taken any time.
A1c test — Taken any time; it shows your blood-glucose levels over several months.
Oral glucose test — A multi-step test taken first after an eight-hour fast, then in three one-hour intervals after you’ve had a sugary drink in the lab.
If a HealthTap doctor determines that it’s medically necessary, they can order any of these tests. Taking one would require traveling to an in-person lab or clinic. Schedule an appointment with your doctor if you have questions about being tested.
Even for groups who are genetically more likely to develop type 2 diabetes, there are many lifestyle choices that can be made to help prevent it from happening.
One of the best ways to avoid prediabetes or type 2 diabetes is to keep your weight in check. A “healthy weight” is different for everyone. If you’re not sure if you’re in a healthy range, talk to your doctor.
Also, be aware that weight isn’t everything. Someone who is overweight isn’t necessarily at risk for type 2 diabetes, just as someone who’s at a healthy weight can still be at risk.
Regular aerobic exercise and resistance training (e.g. weight lifting, yoga, bodyweight exercises) may help ward off insulin resistance and therefore reduce the risk of developing diabetes.
It’s a good idea for most people to aim to exercise most days of the week for at least 30 minutes per day. But for people with mobility issues or a history of injuries, it’s best to consult with a doctor first on what forms of exercise might be safest.
In addition to exercise, it’s helpful to come at this from the opposite angle: Reduce sedentary activity. Many of us work desk jobs that keep us off our feet for large swaths of the day. We could all benefit from more breaks where we’re up and moving around.
Healthy eating is a major factor in the prevention and treatment of type 2 diabetes.
What to eat (and what not to) is incredibly subjective. What’s right for one person can be completely wrong for another. But as a general starting point, the advice we’ve all heard for years still stands — eat more vegetables and fewer processed and packaged foods.
For people who have been diagnosed as prediabetic or with type 2 diabetes, their doctor may recommend a low-fat, low-glycemic diet.
A type 2 diabetes diagnosis will undoubtedly change a person’s life. But compared to other serious health conditions, it’s incredibly manageable. In fact, most people manage the condition on their own and get support from periodic check-ins with their doctor.
A diabetes management plan will look different for everyone, but could include one or more of the following:
There is no cure for type 2 diabetes.
But the right treatment plan and diligent adherence to that plan can effectively bring the condition under control for many people.
