Can You Have Diabetes and Not Know It?
People with type 2 diabetes often have no symptoms at first. They may not have symptoms for many years.
According to Medlineplus.gov, early symptoms of diabetes caused by a high blood sugar level may include:
- Bladder, kidney, skin, or other infections that are more frequent or heal slowly
- Increased thirst
- Increased urination
- Blurred vision
After many years, diabetes can lead to serious health problems, and as a result, many other symptoms. Internal Medicine physicians help keep diabetes patients healthy with regular monitoring.
What is diabetes?
When you have diabetes, your body doesn't make enough insulin. Or it can't use the insulin it makes. Insulin is a hormone. It helps sugar enter the cells to be used as energy. Without insulin, too much sugar collects in your blood.
There are 3 types of diabetes. They are type 1, type 2, and gestational diabetes.
What is prediabetes?
Prediabetes often happens before type 2 diabetes. Prediabetes is when blood sugar levels are higher than normal. But not as high as for diabetes. Many people with prediabetes will have type 2 diabetes within 10 years. More than 1 in 3 U.S. adults have prediabetes. And most of them don't know the risks they face. Prediabetes also raises the risk for heart disease and stroke.
You can delay type 2 diabetes. Or even prevent it. You can do this by making lifestyle changes. These include losing extra weight if you are overweight. And getting more exercise. If you are overweight, losing 5% to 7% of your weight can help. Aim for at least 150 minutes a week of physical activity. Don't let more than 2 days go by without being active. Ask your healthcare provider for a referral to a lifestyle intervention program. This program will help you get to and stay at a 7% weight loss and increase physical activity.
Experts also advise all adults to spend less time sitting and being inactive. This is even more important if you have type 2 diabetes. If you do sit for a long time, get up for some light activity every 30 minutes.
How does diabetes affect blood sugar?
Your pancreas makes insulin. Insulin is needed for glucose to move into the body's cells for energy. Normally insulin is available for this.
When you have diabetes, your pancreas makes little or no insulin. Or your body's cells don’t respond to the insulin that’s made. This causes sugar to build up in the blood. But your body's cells need sugar. Without it, they don't have enough fuel to work as they should.
The 3 main types of diabetes all lead to a buildup of blood sugar. This happens because of problems with insulin. But each type has a different cause and treatment:
- Type 1 diabetes. Type 1 diabetes is an autoimmune disease. The body's immune system destroys the cells in the pancreas that make insulin. This means your body makes little or no insulin. People with type 1 diabetes must take insulin every day to live. About 1 in 20 people with diabetes have type 1.
- Type 2 diabetes. Type 2 diabetes happens when the body can't make enough insulin. Or the body can't use it correctly. Type 2 may be controlled with diet, exercise, and weight loss. It can also be controlled with medicine taken by mouth. Or with insulin injections. About 9 in 10 to 19 in 20 people with diabetes have type 2.
- Gestational diabetes. This type happens during pregnancy. It affects women who did not have diabetes before they got pregnant. They can't use the insulin their body makes. This type of diabetes often goes away after the baby is born. If it doesn't, it likely was not gestational diabetes. It was more likely type 1 or type 2 diabetes that began during pregnancy. Gestational diabetes may be controlled with diet and exercise, and by watching weight gain. Women with this type may need to take medicines to control blood sugar. They may be at higher risk for type 2 later in life.
Complications of diabetes
Complications of diabetes include:
- Eye problems and blindness
- Heart disease
- Nervous system problems
- Loss of a limb
- Kidney disease
Except for gestational diabetes, diabetes is an ongoing (chronic) disease that can't be cured. It affects nearly every part of the body. It can lead to other serious diseases. And it can be life-threatening. You must work with a healthcare provider to manage your diabetes. With the correct care, you can prevent the serious problems of the disease. Or stop them from getting worse.
Many people manage diabetes under the supervision of a primary care physician, and in some cases, they are referred to an endocrinology specialist. If you don’t have a primary care physician, visit PIHHealth.org/doctors or call 562.789.5982 to speak with someone who can help you find a provider.
