What Is Type 2 Diabetes?
Type 2 diabetes is a lifelong disease that keeps your body from using insulin the way it should. People with type 2 diabetes are said to have insulin resistance.
People who are middle-aged or older are most likely to get this kind of diabetes. It used to be called adult-onset diabetes. But type 2 diabetes also affects kids and teens, mainly because of childhood obesity.
Symptoms of type 2 Diabetes
In type 2 diabetes, your body isn’t able to effectively use insulin to bring glucose into your cells. This causes your body to rely on alternative energy sources in your tissues, muscles, and organs. This is a chain reaction that can cause a variety of symptoms.
Type 2 diabetes can develop slowly. The symptoms may be mild and easy to dismiss at first. The early symptoms may include:
- constant hunger
- a lack of energy
- fatigue
- weight loss
- excessive thirst
- frequent urination
- dry mouth
- itchy skin
- blurry vision
As the disease progresses, the symptoms become more severe and potentially dangerous.
If your blood glucose levels have been high for a long time, the symptoms can include:
- yeast infections
- slow-healing cuts or sores
- dark patches on your skin, a condition known as acanthosis nigricans
- foot pain
- feelings of numbness in your extremities, or neuropathy
If you have two or more of these symptoms, you should see your doctor. Without treatment, diabetes can become life-threatening. Discover other symptoms of type 2 diabetes.
Causes of type 2 Diabetes
Insulin is a naturally occurring hormone. Your pancreas produces it and releases it when you eat. Insulin helps transport glucose from your bloodstream to cells throughout your body, where it’s used for energy.
If you have type 2 diabetes, your body becomes resistant to insulin. Your body is no longer using the hormone efficiently. This forces your pancreas to work harder to make more insulin.
Over time, this can damage cells in your pancreas. Eventually, your pancreas may not be able to produce any insulin.
If you don’t produce enough insulin or if your body doesn’t use it efficiently, glucose builds up in your bloodstream. This leaves your body’s cells starved for energy. Doctors don’t know exactly what triggers this series of events.
It may have to do with cell dysfunction in the pancreas or with cell signaling and regulation. In some people, the liver produces too much glucose. There may be a genetic predisposition to developing type 2 diabetes.
There’s definitely a genetic predisposition to obesity, which increases the risk of insulin resistance and diabetes. There could also be an environmental trigger.
Most likely, it’s a combination of factors that increases the risk of type 2 diabetes. Find out more about the causes of diabetes.
Treatment for type 2 Diabetes
You can effectively manage type 2 diabetes. Your doctor will tell you how often you should check your blood glucose levels. The goal is to stay within a specific range.
Follow these tips to manage type 2 diabetes:
- Include foods rich in fiber and healthy carbohydrates in your diet. Eating fruits, vegetables, and whole grains will help keep your blood glucose levels steady.
- Eat at regular intervals
- Only eat until you’re full.
- Control your weight and keep your heart healthy. That means keeping refined carbohydrates, sweets, and animal fats to a minimum.
- Get about half an hour of aerobic activity daily to help keep your heart healthy. Exercise helps to control blood glucose, too.
Your doctor will explain how to recognize the early symptoms of blood sugar that’s too high or too low and what to do in each situation. They’ll also help you learn which foods are healthy and which foods aren’t.
Not everyone with type 2 diabetes needs to use insulin. If you do, it’s because your pancreas isn’t making enough insulin on its own. It’s crucial that you take insulin as directed. There are other prescription medications that may help as well.
