Diabetes - Animation

Diabetes is on the rise worldwide, and is a serious, lifelong disease that can lead to heart disease, stroke, and lasting nerve, eye and foot problems. Let's talk about diabetes and the difference between the three types of diabetes. So, what exactly is diabetes and where does it come from? An organ in your body called the pancreas produces insulin, a hormone that controls the levels of your blood sugar. When you have too little insulin in your body, or when insulin doesn't work right in your body, you can have diabetes, the condition where you have abnormally high glucose or sugar levels in your blood. Normally when you eat food, glucose enters your bloodstream. Glucose is your body's source of fuel. Your pancreas makes insulin to move glucose from your bloodstream into muscle, fat, and liver cells, where your body turns it into energy. People with diabetes have too much blood sugar because their body cannot move glucose into fat, liver, and muscle cells to be changed into and stored for energy. There are three major types of diabetes. Type 1 diabetes happens when the body makes little or no insulin. It usually is diagnosed in children, teens, or young adults. But about 80% of people with diabetes have what's called Type 2 diabetes. This disease often occurs in middle adulthood, but young adults, teens, and now even children are now being diagnosed with it linked to high obesity rates. In Type 2 diabetes, your fat, liver, and muscle cells do not respond to insulin appropriately. Another type of diabetes is called gestational diabetes. It's when high blood sugar develops during pregnancy in a woman who had not had diabetes beforehand. Gestational diabetes usually goes away after the baby is born. But, still pay attention. These women are at a higher risk of type 2 diabetes over the next 5 years without a change in lifestyle. If you doctor suspects you have diabetes, you will probably have a hemoglobin A1c test. This is an average of your blood sugar levels over 3 months. You have pre-diabetes if your A1c is 5.7% to 6.4%. Anything at 6.5% or higher indicates you have diabetes. Type 2 diabetes is a wake up call to focus on diet and exercise to try to control your blood sugar and prevent problems. If you do not control your blood sugar, you could develop eye problems, have problems with sores and infections in your feet, have high blood pressure and cholesterol problems, and have kidney, heart, and problems with other essential organs. People with Type 1 diabetes need to take insulin every day, usually injected under the skin using a needle. Some people may be able to use a pump that delivers insulin to their body all the time. People with Type 2 diabetes may be able to manage their blood sugar through diet and exercise. But if not, they will need to take one or more drugs to lower their blood sugar levels. The good news is, people with any type of diabetes, who maintain good control over their blood sugar, cholesterol, and blood pressure, have a lower risk of kidney disease, eye disease, nervous system problems, heart attack, and stroke, and can live, a long and healthy life.

Causes

Insulin is a hormone produced by the pancreas to control blood sugar. Diabetes can be caused by too little insulin, resistance to insulin, or both.

To understand diabetes, it is important to first understand the normal process by which food is broken down and used by the body for energy. Several things happen when food is digested and absorbed:

  • A sugar called glucose enters the bloodstream. Glucose is a source of fuel for the body.
  • An organ called the pancreas makes insulin. The role of insulin is to move glucose from the bloodstream into muscle, fat, and other cells, where it can be stored or used as fuel.

People with diabetes have high blood sugar because their body cannot move sugar from the blood into muscle and fat cells to be burned or stored for energy, and/or because their liver makes too much glucose and releases it into the blood. This is because either:

  • Their pancreas does not make enough insulin
  • Their cells do not respond to insulin normally
  • Both of the above

There are two major types of diabetes. The causes and risk factors are different for each type:

  • Type 1 diabetes is less common. It can occur at any age, but it is most often diagnosed in children, teens, or young adults. In this disease, the body makes little or no insulin. This is because the pancreas cells that make insulin stop working. Daily injections of insulin are needed. The exact cause of the failure to make enough insulin is unknown.
  • Type 2 diabetes is more common. It most often occurs in adulthood, but because of high obesity rates, children and teens are now being diagnosed with this disease. Some people with type 2 diabetes do not know they have it. With type 2 diabetes, the body is resistant to insulin and doesn't use insulin as well as it should. Not all people with type 2 diabetes are overweight or obese.
  • There are other causes of diabetes, and some people cannot be classified as type 1 or type 2.

Gestational diabetes is high blood sugar that develops at any time during pregnancy in a woman who does not already have diabetes.

If your parent, brother, or sister has diabetes, you may be more likely to develop the disease.

Type 2 Diabetes Facts Quiz

  • If you eat too much sugar over a long time, you may develop type 2 diabetes.

    Correct Answer
    The correct answer is: "False." Diabetes is caused by a problem in the way your body makes or uses the hormone insulin. Insulin helps move blood sugar (glucose) into cells, where it is stored to be used for energy. Eating too much sugar won't cause diabetes. But it may make you overweight, which can put you at risk for diabetes. In addition, eating too much sugar or other dietary carbohydrate can raise the blood sugar of someone with diabetes.
  • Being overweight makes it harder for your body to properly use insulin.

    Correct Answer
    The correct answer is: "True." Extra fat in the body makes it harder for the body to use insulin properly. This is called insulin resistance. Losing excess weight and being physically active can help prevent or reverse insulin resistance.
  • Which of the following health conditions does NOT put you at risk for type 2 diabetes?

    Correct Answer
    The correct answer is: "Asthma." All of the other conditions increase your risk for diabetes. If you have any of these conditions, work with your doctor to control your risk factors for diabetes and heart disease.
  • You can have diabetes for years and not know it.

    Correct Answer
    The correct answer is: "True." That's why it's important to talk with your doctor about whether you should have diabetes screening tests. People with high blood pressure, who are age 45 and older, and those who are overweight and have other risk factors should consider being tested for diabetes.
  • What are early symptoms of type 2 diabetes?

    Correct Answer
    The correct answer is: "All of the above." If you notice any of these symptoms, talk with your doctor.
  • If you have a blood sugar level higher than ____ , your doctor may test you for diabetes.

    Correct Answer

    The correct answer is: "200 mg/dL." If your blood sugar is at this level, your doctor may give you these tests to confirm that you have diabetes:

    • Fasting blood glucose level -- diabetes: 126 mg/dL or higher, on 2 separate occasions
    • Hemoglobin A1c test -- diabetes: 6.5% or higher
    • Oral glucose tolerance test -- diabetes: 200 mg/dL or higher after 2 hours

  • What health care problems are caused by diabetes?

    Correct Answer

    The correct answer is: "All of the above." Over time, too much sugar in the blood can harm your eyes, kidneys, nerves, skin, heart, and blood vessels. Talk with your doctor about the best ways to keep your blood sugar, blood pressure, and cholesterol level in a healthy range.

  • Which are treatments for type 2 diabetes?

    Correct Answer

    The correct answer is: "All of the above." The main treatment for type 2 diabetes is diet and exercise. If you still have trouble managing your blood sugar level, you may need medicine or insulin. Work with your health care provider to learn how much fat, protein, and carbohydrates you need in your diet.

  • If you have type 2 diabetes, you will have to inject insulin.

    Correct Answer

    The correct answer is: "Maybe." Many people can control type 2 diabetes with diet and exercise and diabetes medicines, if needed. However, if your blood sugar remains uncontrolled, you may need to inject insulin.

  • Having diabetes increases your risk for heart disease.

    Correct Answer

    The correct answer is: "True." Diabetes directly affects your heart, plus it can make it harder to control cholesterol without taking medications to lower your cholesterol level. This can lead to heart disease and other problems. A healthy diet, regular exercise, and eating less salt can help control diabetes, blood pressure, and cholesterol. This will reduce your risk of heart disease.

  • Some people with diabetes no longer need medicine if they lose weight and exercise.

    Correct Answer

    The correct answer is: "True." Some people with type 2 diabetes no longer need medicine if they lose weight and become more active. When they reach their ideal weight, their body's own insulin and a healthy diet may be able to control their blood sugar levels. However, ongoing monitoring of type 2 diabetes is still recommended.

Symptoms

A high blood sugar level can cause several symptoms, including:

Because type 2 diabetes develops slowly, some people with high blood sugar have no symptoms.

Symptoms of type 1 diabetes develop over a short period. People may be very sick by the time they are diagnosed.

After many years, diabetes can lead to other serious problems. These problems are known as diabetes complications, and include:

  • Eye problems, including trouble seeing (especially at night), light sensitivity, and blindness
  • Sores and infections of the leg or foot, which if untreated, can lead to amputation of the leg or foot
  • Damage to nerves in the body, causing pain, tingling, a loss of feeling, problems digesting food, and erectile dysfunction
  • Kidney problems, which can lead to kidney failure
  • Weakened immune system, which can lead to more frequent infections
  • Increased chance of having a heart attack or stroke

Exams and Tests

A urine analysis may show high blood sugar. But a urine test alone does not diagnose diabetes.

Your health care provider may suspect that you have diabetes if your blood sugar level is higher than 200 mg/dL (11.1 mmol/L). To confirm the diagnosis, one or more of the following tests must be done.

Blood tests:

  • Fasting blood glucose level. Diabetes is diagnosed if the fasting glucose level is 126 mg/dL (7.0 mmol/L) or higher on two different tests. Levels between 100 and 125 mg/dL (5.5 and 7.0 mmol/L) are called impaired fasting glucose or prediabetes. These levels are risk factors for type 2 diabetes.
  • Hemoglobin A1C (A1C) test. Normal is less than 5.7%; prediabetes is 5.7% to 6.4%; and diabetes is 6.5% or higher.
  • Oral glucose tolerance test. Diabetes is diagnosed if the glucose level is 200 mg/dL (11.1 mmol/L) or higher 2 hours after drinking a special 75 gram sugar drink (this test is used more often for type 2 diabetes).

Video Transcript

HbA1c - Animation

If you have diabetes, it's important to keep tight control of your blood sugar. The Hemoglobin A1c test, or HbA1C test, is one way to find out if you are in control. Hemoglobin is an important part of the red blood cell. Red blood cells live about three months. During the life of a red blood cell, sugar molecules, also floating around in your blood, tend to want to stick to the hemoglobin of your red blood cells. Identifying these sugar molecules allows us to get an approximate three-month average of how high persons blood sugars have been. The HbA1c test helps us diagnose a patient suspected of having diabetes and monitors the blood sugar of a diabetic patient. Now, how do we screen for diabetes? If your doctor suspects you have diabetes, your physician will order this simple blood test. A normal HbA1c level is less than 6.0%, which is a three month blood sugar average of around 126 milligrams per deciliter, written like this in your lab results. (126 mg/dl). A HgbA1c level of 5.7 to 6.4% means you are pre-diabetic or borderline-diabetic. If your HgbA1C is 6.5% or higher, you are considered to be a diabetic. That correlates roughly to a 3-month blood sugar average of 140. So, if you are a diabetic, what level should your HbA1c be? Through a combination of a good diabetic diet that controls for carbohydrates, proteins, fats and calories, the American Diabetes Association currently recommends a HbA1C goal of less than 7%. I should also point out that the American Association of Clinical Endocrinologists recommends an even stricter control of diabetes - with a recommended goal of less than 6.5%. What we do know is diabetes causes permanent and irreversible damage to the nerves, blood vessels and body organs, like your eyes, kidneys, heart and also your feet. So, it's critical to get and keep your diabetes under good control to avoid serious long-term health problems. People often ask -- How often should a hemoglobin A1C test be done IF you are a diabetic? Since the HbA1c Test reflects 3 months of control, I recommend getting checked every 3 months to let you, and your doctor know how you're doing. Remember, if you have diabetes, keeping good control of your blood sugar reduces your risk for long-term health problems, like Eye, heart, kidney problems, and even stroke. See your doctor for HbA1c tests every 3 months; you'll be glad you did.

Screening for type 2 diabetes in people who have no symptoms is recommended for:

  • Overweight children who have other risk factors for diabetes, starting at age 10 and repeated every 3 years
  • Overweight or obese adults (BMI of 25 or higher) starting at age 35
  • Overweight women who have other risk factors such as high blood pressure who are planning to become pregnant
  • All adults over age 35, repeated every 3 years or at a younger age if the person has risk factors such as high blood pressure, or having a mother, father, sister, or brother with diabetes

Treatment

Type 2 diabetes can sometimes be reversed with lifestyle changes, especially losing weight with exercise and by eating healthier foods. Some cases of type 2 diabetes can also be improved with weight loss surgery.

There is no cure for type 1 diabetes (except for a pancreas or islet cell transplant).

Treating either type 1 diabetes or type 2 diabetes involves nutrition, activity and medicines to control blood sugar level.

Everyone with diabetes should receive proper education and support about the best ways to manage their diabetes. Ask your provider about seeing a certified diabetes educator (CDE).

Getting better control over your blood sugar, cholesterol, and blood pressure levels helps reduce the risk for kidney disease, eye disease, nervous system disease, heart attack, and stroke.

To prevent diabetes complications, visit your provider at least 2 to 4 times a year. Talk about any problems you are having. Follow your provider's instructions on managing your diabetes.

Support Groups

Many resources can help you understand more about diabetes. If you have diabetes, you can also learn ways to manage your condition and prevent diabetes complications.

Outlook (Prognosis)

Diabetes is a lifelong disease for most people who have it.

Tight control of blood glucose can prevent or delay diabetes complications. But these problems can occur, even in people with good diabetes control.

Possible Complications

After many years, diabetes can lead to serious health problems:

  • You could have eye problems, including trouble seeing (especially at night), and light sensitivity. You could become blind.
  • Your feet and skin can develop sores and infections. After a long time, your foot or leg may need to be amputated. Infection can also cause pain and itching in other parts of the body.
  • Diabetes may make it harder to control your blood pressure and cholesterol. This can lead to a heart attack, stroke, and other problems. It can become harder for blood to flow to your legs and feet.
  • Nerves in your body can get damaged, causing pain, tingling, and numbness.
  • Because of nerve damage, you could have problems digesting the food you eat. You could feel weakness or have trouble going to the bathroom. Nerve damage can make it harder for men to have an erection.
  • High blood sugar and other problems can lead to kidney damage. Your kidneys may not work as well as they used to. They may even stop working so that you need dialysis or a kidney transplant.
  • Your immune system can weaken, which can lead to frequent infections.

Prevention

Keeping an ideal body weight and an active lifestyle may prevent or delay the start of type 2 diabetes. If you're overweight, losing just 5% of your body weight can reduce your risk. Some medicines can also be used to delay or prevent the start of type 2 diabetes.

At this time, type 1 diabetes cannot be prevented. But there is promising research that shows type 1 diabetes may be delayed in some high risk people.

Endocrine glands

Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body. For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the rate of metabolism in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).

Diabetes - Animation

Diabetes is on the rise worldwide, and is a serious, lifelong disease that can lead to heart disease, stroke, and lasting nerve, eye and foot problems. Let's talk about diabetes and the difference between the three types of diabetes.

So, what exactly is diabetes and where does it come from?

An organ in your body called the pancreas produces insulin, a hormone that controls the levels of your blood sugar. When you have too little insulin in your body, or when insulin doesn't work right in your body, you can have diabetes, the condition where you have abnormally high glucose or sugar levels in your blood.

Normally when you eat food, glucose enters your bloodstream. Glucose is your body's source of fuel. Your pancreas makes insulin to move glucose from your bloodstream into muscle, fat, and liver cells, where your body turns it into energy. People with diabetes have too much blood sugar because their body cannot move glucose into fat, liver, and muscle cells to be changed into and stored for energy.

There are three major types of diabetes. Type 1 diabetes happens when the body makes little or no insulin. It usually is diagnosed in children, teens, or young adults. But about 80% of people with diabetes have what's called Type 2 diabetes. This disease often occurs in middle adulthood, but young adults, teens, and now even children are now being diagnosed with it linked to high obesity rates. In Type 2 diabetes, your fat, liver, and muscle cells do not respond to insulin appropriately.

Another type of diabetes is called gestational diabetes. It's when high blood sugar develops during pregnancy in a woman who had not had diabetes beforehand. Gestational diabetes usually goes away after the baby is born. But, still pay attention. These women are at a higher risk of type 2 diabetes over the next 5 years without a change in lifestyle.

If you doctor suspects you have diabetes, you will probably have a hemoglobin A1c test. This is an average of your blood sugar levels over 3 months. You have pre-diabetes if your A1c is 5.7 to 6.4%. Anything at 6.5% or higher indicates you have diabetes.

Type 2 diabetes is a wake up call to focus on diet and exercise to try to control your blood sugar and prevent problems. If you do not control your blood sugar, you could develop eye problems, have problems with sores and infections in your feet, have high blood pressure and cholesterol problems, and have kidney, heart, and problems with other essential organs.

People with Type 1 diabetes need to take insulin every day, usually injected under the skin using a needle. Some people may be able to use a pump that delivers insulin to their body all the time.

People with Type 2 diabetes may be able to manage their blood sugar through diet and exercise. But if not, they will need to take one or more drugs to lower their blood sugar levels.

The good news is, people with any type of diabetes, who maintain good control over their blood sugar, cholesterol, and blood pressure, have a lower risk of kidney disease, eye disease, nervous system problems, heart attack, and stroke, and can live, a long and healthy life.
