Diabetes
Diabetes Overview
Diabetes occurs when your body can’t properly convert food into energy due to a lack of insulin, a vital hormone produced by the pancreas, or because of the body’s inability to use insulin. When your body is functioning correctly, most of the food you eat is converted into glucose, a form of sugar, and moved into your cells. When you have diabetes, the sugar builds up in your blood instead of moving into the cells. Too much sugar in the blood can lead to serious problems, including heart disease and damage to the nerves and kidneys.
Types of Diabetes
- Type 1 diabetes - Once called “juvenile diabetes”, type 1 diabetes is diagnosed when the pancreas makes little or no insulin. People with type 1 diabetes must take insulin every day to live.
- Type 2 diabetes - Once called “adult onset diabetes”, type 2 diabetes is diagnosed when the pancreas still produces some insulin. The body may not be able to use the insulin it makes, or it may not make enough insulin to keep blood glucose in the normal range. People with type 2 diabetes may be able to control it with diet and physical activity. They may also need to take medication, including insulin.
- Gestational diabetes - Three to 7 percent of women have gestational diabetes during pregnancy. Gestational diabetes can often be treated with a healthy meal plan and physical activity, but some women require insulin or other medication. Blood glucose usually returns to normal levels after the baby is born. However, women who have had gestational diabetes are at higher risk for type 2 diabetes later in life.
- Pre-diabetes - With pre-diabetes, blood glucose levels are higher than normal, but they are not yet high enough to be considered diabetes. Pre-diabetes is a warning that progression of the disease is likely unless steps are taken to prevent or delay onset. Even at the pre-diabetes stage, a healthy diet, weight loss and exercise may delay or prevent type 2 diabetes.
Symptoms
Watch for these signs and symptoms if you suspect that you may have diabetes, though some people with diabetes may not exhibit any symptoms at all.
- Blurred vision
- Little or no energy
- Thirst or hunger
- Frequent urination, especially at nigh
- Sudden weight change
- Numbness or tingling in hands or feel
- Slow-healing cuts or sores
- Frequent yeast infections
- Erectile dysfunction<
Risk Factors
- Obesity is the most important risk factor for type 2 diabetes. The more overweight you are, the more resistant your body is to insulin.
- Risk for type 2 diabetes increases with age, especially after age 45.
- Your risk for diabetes is higher if your mother, father or sibling has diabetes.
- A diet high in fat, calories and cholesterol increases your risk of diabetes.
Some ethnic groups have a higher risk of diabetes than others. You are at greater risk if you are:
- Native American
- Hispanic American
- African American
- Pacific Islander
Complications
The American Diabetes Association warns people with uncontrolled diabetes about the possibility of complications including:
- Heart disease and stroke - More than two out of three people with diabetes die with heart disease.
- Kidney disease - Diabetes can weaken the kidney's ability to remove waste products from the blood and increase the risk of kidney disease.
- Eye problems - People with diabetes are more likely to develop glaucoma and cataracts than people without diabetes. Diabetic retinopathy is a leading cause of blindness
- Gum disease - Diabetes increases the odds of developing gum disease.
- Nerve damage - Called diabetic neuropathy, nerve damage generally occurs in people who have had diabetes for a number of years.
- Foot problems - Extra dry skin, loss of sensation in the feet, calluses or foot ulcers are common problems for people with diabetes.
- Skin problems - If you are diabetic and notice a rash, blisters, fungus, cut or any change in the appearance of your skin, contact your Wellstar physician
- Gastroparesis - One of the results of damage to the nerves is a condition that slows the emptying of the stomach following a meal. Called gastroparesis, this condition can make controlling blood glucose even more difficult.
- Depression - People with diabetes are more inclined toward depression than people without diabetes
Contact your Wellstar physician if you experience any of these complications.
Diabetes Prevention
Type 1 diabetes can’t be prevented. However, at Wellstar we believe a healthy lifestyle is the best way to prevent or delay the onset of type 2 diabetes in people who have pre-diabetes or other risk factors for diabetes. Preventive steps you can take include:
- Adopting a healthy diet
- Increasing your level of physical activity
- Maintaining a healthy weight
- Getting educated through Wellstar classes on ways to avoid developing diabetes
Diabetes Diagnosis
There are three different blood tests Wellstar physicians can use to determine if you have diabetes or pre-diabetes. Each test measures your blood glucose, or sugar, level to determine if you are processing glucose correctly.
Diabetes Tests
A1C Test
In 2009 experts began recommending the A1C test as the primary test to diagnose pre-diabetes, type 1 and type 2 diabetes. The A1C test measures your average blood sugar level for the past two to three months by measuring the percentage of your hemoglobin, a protein in red blood cells that is coated with sugar. The higher your A1C level, the less controlled your blood sugar.
- For people without diabetes, a normal A1C level can range from 4.5 to 6 percent. An A1C level of 6.5 percent or higher on two separate tests indicates diabetes.
- A level between 6 and 6.5 percent is considered pre-diabetes.
Fasting Plasma Glucose (FPG) Test
This is the preferred test used to diagnose pre-diabetes, type 2 and gestational diabetes.
- Before the test, fast for eight hours
- Blood is drawn.
- Drink a sugary solution.
- Blood is drawn one or more times over a two to three hour period.
Results for pre-diabetes and type 2 diabetes test:
- A blood sugar level lower than 99 mg/dL is normal.
- A blood sugar level between 100 mg/dL and 125 mg/dL indicates a form of pre-diabetes called impaired fasting glucose (IFG).
- A blood sugar level of 126 mg/dL or higher may indicate diabetes.
If the test indicates type 2 diabetes, your Wellstar physician may repeat it on another day or use another blood test to confirm the diagnosis.
Oral Glucose Tolerance (OGTT) Test
- This test, which is seen as more reliable than the FPG test, is also less convenient.
- Before the test, fast for eight hours.
- Drink a sugary solution.
- Blood is drawn two hours after drinking the solution
Results for pre-diabetes and type 2 diabetes test:
- A blood sugar level lower than 140 mg/dL is normal.
- A blood sugar level between 140 mg/dL and 199 mg/dL indicates a form of pre-diabetes impaired glucose tolerance (IGT).
- A blood sugar level of 200 mg/dL or higher may indicate diabetes.
If the test indicates type 2 diabetes, your Wellstar physician may repeat it on another day or use another blood test to confirm the diagnosis.
Results of either test for gestational diabetes:
Your Wellstar physician will look at the results of the blood sugar tests taken at one, two and three hours after you drink the glucose solution. If two or three of the tests are higher than normal, you'll be diagnosed with gestational diabetes.
- After one hour, a normal blood sugar level is lower than 180 mg/dL
- After two hours, a normal blood sugar level is lower than 155 mg/dL.
- After three hours, a normal blood sugar level is lower than 140 mg/dL
Diabetes Treatment
Making healthy diet and exercise choices are important no matter what type of diabetes you have. Depending on the type, insulin or medication may also be part of your treatment. Your Wellstar physician will determine the best course of treatment based on the type of diabetes you have.
Pre-diabetes
Healthy dietary and exercise choices by those with pre-diabetes can help bring blood sugar levels into the normal range or keep levels from rising into the type 2 diabetes range. For people at high risk of diabetes or whose pre-diabetes is getting worse, diabetes drugs are an option.
Type 1 and Type 2
If you have type 1 or type 2 diabetes you must monitor your blood sugar. In addition, insulin and/or diabetes medications may be part of your treatment.
Monitoring your blood sugar—You will need to check and record your blood sugar from several times a day to several times a week depending on your treatment plan. Regular monitoring is the only way to ensure your blood sugar level remains in your target range. Blood sugar levels can change in response to a variety of influences, including food, physical activity, medication, illness, alcohol, stress and—for women—fluctuations in hormone levels.
A1C testing may also be part of your treatment plan. Daily testing gives your blood sugar level at that moment. A1C measures your average blood sugar level for the past two to three months, which provides a good indication of how well your treatment is working.
Insulin - Everyone who has type 1 diabetes must take insulin to survive. Some people with type 2 diabetes also need insulin. Insulin can be delivered into the body in several ways, including:
- Injecting with a needle and syringe
- Using an insulin pen, which looks like an ink pen with an insulin-filled cartridge
- Using an insulin pump, which is a small device worn on your body. The pump delivers specific amounts of insulin automatically through a catheter under the skin of your abdomen
Medications
Other medications may be prescribed for people with type 2 diabetes who still produce some insulin. Some of these medications stimulate your pancreas to produce and release insulin. Some inhibit the production and release of glucose, which means your body needs less insulin. Some block the stomach enzymes that break down carbohydrates or make your tissues more sensitive to insulin. These drugs may be given in combination as needed.
Pancreas transplant
Because the side effects of transplant can be worse than diabetes, pancreas transplants are not considered except in cases where type 1 diabetes can’t be controlled or where complications are serious.
Gestational Diabetes
In addition to a healthy diet and exercise, treatment for gestational diabetes may include blood sugar monitoring and insulin. Your blood sugar level will also be monitored during labor.
Ongoing Care for Diabetes
Type 1 and type 2 diabetes are chronic, lifelong conditions that require a commitment to ongoing care if you are to live well. Pay special attention to these parts of your life:
- Diet - There is no diabetes diet. You’ll need to eat fruit, vegetables and whole grains, foods that are good for your entire family. You can even have desserts once in a while if they are included in your treatment plan. Your Wellstar physician and a registered dietician can help you develop a meal plan to fit your lifestyle and help you maintain good health.
- Physical activity - Everyone needs regular exercise, including people with diabetes. Talk to your Wellstar physician before developing an exercise routine. Then plan at least 30 minutes of aerobic exercise most days of the week. If you haven't been active for a while, start slowly and build.
- Teeth - People with diabetes are prone to gum disease and infection. Brush and floss your teeth at least twice a day. See your Wellstar dentist at least twice a year and right away if your gums bleed or appear red or swollen.
- Physical exams - Schedule yearly physical exams so that your Wellstar physician can look for diabetes-related complications and other medical problems.
- Eyes - An annual eye exam gives your Wellstar ophthalmologist the opportunity to check for signs of retinal damage, cataracts and glaucoma.
- Immunizations and vaccinations - Because high blood sugar can weaken your immune system, get an annual flu shot and a tetanus booster shot every 10 years. Your Wellstar physician may recommend other vaccines as well.
- Feet - Poor circulation can cause serious foot sores and infections. Wash and moisturize your feet every day. Check them for blisters, cuts, sores, redness or swelling. If you have a sore or other foot problem that doesn't begin to heal in a few days call your Wellstar physician.
- Blood pressure and cholesterol - Control high blood pressure and high cholesterol through diet and, if necessary, medication.
- Quit smoking - Smoking greatly increases the risk of various diabetes complications, including heart attack, stroke, nerve damage and kidney disease. Talk to your Wellstar physician about ways to stop smoking.
- Alcohol - Alcohol can cause high or low blood sugar, depending on how much you drink and whether you eat at the same time. If you drink, drink in moderation and always with a meal.
- Stress - Learn to control stress. The hormones your body may produce in response to stress can prevent insulin from working properly.
