Is there anything that can help to prevent the onset of type 2 diabetes?
One of the most important factors in the development of
diabetes is genetics (which we have no control over). However, there are things in our environment we
can control to lower our personal risk of developing diabetes. And, frankly,
none of it is magic.
Exercise
Yes folks - it is true. Exercise is good for you. When adjusted for family
history, the benefits of exercise can be broken down based on previous studies;
for every 500 kcal burned weekly through exercise, there is a 6% decrease in
relative risk for the development of diabetes. This data is from a study done in
men who were followed over a period of 10 years. The study also notes a greater
benefit in men who were heavier at baseline. There have been similar reports on
the effects of exercise in women.
Exercise is thought to be a major determinant of insulin sensitivity in
muscle tissue. By increasing exercise, the body uses insulin more efficiently -
for up to 70 hours after the exercise period has occurred. Thus exercising 3-4
times per week would be beneficial in most people.
The same benefits are seen when looking specifically at
patients with impaired glucose tolerance/impaired fasting glucose. When
diet and
exercise are used as tools in this population over a six year study and compared
to a control group, glucose tolerance improves by about 76% compared to deterioration in 67%
of the control group. The exercise group also had a lesser rate of progression
to type 2 diabetes.
It should be noted that a lot of the benefit of exercise occurs independent
of weight loss. However, when combined with weight loss, the benefits increase
substantially.
Weight Loss
In patients at risk for diabetes,
weight loss can improve insulin
sensitivity, delay, and even prevent progression to type 2 diabetes. In patients
with overt diabetes, weight loss can play a tremendous role in improving blood
sugar control.
Two large studies - one in Finland and the other one U.S. (the Diabetes
Prevention Program- DPP) have shown the benefit of weight loss in diabetes
prevention. In the Finnish study, more than 500 men and women with impaired
glucose tolerance were assigned to a control group or an exercise/weight loss
group. By the end of the study, the weight loss group had lost about 8 pounds,
and the control group about 2 pounds. The weight loss group had significantly
less participants develop diabetes than the control group.
The DPP study showed a similar result. In this study, there was also a group taking
metformin (Glucophage) as a preventative measure. At the end of the study, the
lifestyle group actually did better at prevention of diabetes than those taking
metformin. In fact, the study was stopped early, because the benefit of weight
loss (the weight loss group lost about 15 pounds on average and kept it off) was
so dramatic. That just about says it all!
Smoking
Smoking more than 20 cigarettes a day can increase your risk of developing
diabetes to more than three times that of nonsmokers. The exact reason for this
isn't well understood. It may be that smoking directly decreases the body's
ability to utilize insulin. Moreover, it has been observed that after smoking,
blood sugar levels increase. Finally, there is also an association between
smoking and body fat distribution - smoking tends to encourage the "apple" shape
- which is a risk factor for diabetes.
So.....that's one more reason to quit, right?
Nuts
In as study of over 83,000 women, nuts (and peanut butter) consumption seemed
to show some protective effect against the development of diabetes. Women who
have more than five one-ounce servings of nuts a week lowered their risk of
developing diabetes compared to women who consumed no nuts at all.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
A stroke results from impaired oxygen delivery to brain cells via the bloodstream. A stroke is also referred to as a CVA, or cerebrovascular incident. Symptoms of stroke include: sudden numbness or weakness of the face, arm or leg. Sudden confusion, trouble speaking or understanding. Sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, or loss of balance, and/or sudden severe headache with no known cause. A TIA, or transient ischemic attack is a short-lived temporary impairment of the brain caused by loss of blood supply. Stroke is a medical emergency.
Hypoglycemia is a syndrome caused by low blood sugar. Symptoms of hypoglycemia include palpitations, trembling, intense hunger, sweating, nervousness, and weakness. Consuming lifesavers, table sugar, soda, and juice are good treatment options for hypoglycemia.
Insulin resistance is the diminished ability of cells to respond to the action of insulin in transporting glucose (sugar) from the bloodstream into muscle and other tissues. Causes of insulin can include conditions such as stress, obesity, metabolic syndrome, and steroid use. Some of the risk factors for insulin resistance include fatty liver, heart disease, strokes, peripheral vascular disease, high cholesterol, and smoking. Treatment for insulin resistance are lifestyle changes and if necessary, medication.
Heart disease (coronary artery disease) is caused by a buildup of cholesterol deposits in the coronary arteries. Risk factors for heart disease include smoking, high blood pressure, heredity, diabetes, peripheral artery disease, and obesity. Symptoms include chest pain and shortness of breath. There are a variety of tests used to diagnose coronary artery disease. Treatment includes life-style changes, medications, procedures, or surgery.
Obesity is the state of being well above one's normal weight. A person has traditionally been
considered to be obese if they are more than 20 percent over their ideal weight.
That ideal weight must take into account the person's height, age, sex, and
build.
The major goal in treating diabetes is controlling elevated blood sugar without causing abnormally low levels of blood sugar. Treatment for type 1 diabetes is with insulin, exercise, and a diabetic diet. Treatment for type 2 diabetes is first treated with weight reduction, a diabetic diet, and exercise. When these measures fail to control the elevated blood sugar, oral medications are used. If oral medications are still insufficient, insulin medications are considered.
The main features of metabolic syndrome include insulin resistance, hypertension (high blood pressure), cholesterol abnormalities, and an increased risk for clotting. Patients are most often overweight or obese. Lifestyle modification such as the Mediterranean diet, exercise, and quitting smoking are the preferred treatment of metabolic syndrome.
Turner syndrome is an inherited chromosomal condition affecting women. Women with Turner syndrome do not have ovarian function, and features of the syndrome include webbed neck, lymphedema of the hands and feet, heart defects, kidney problems, and skeletal abnormalities. The X chromosome is related to Turner syndrome. Treatment focuses on the symptoms of the syndrome.
Renal artery stenosis is a narrowing of the diameter of the renal arteries. When the renal arteries narrow, the result is restricted blood flow to the kidneys, which may lead to impaired kidney function and high blood pressure (referred to as renovascular hypertension (RVHT). Renal artery stenosis can occur in one or both kidneys. The primary cause of renal artery stenosis is atherosclerosis. Risk factors for renal artery stenosis include high blood pressure, high cholesterol levels, age, cigarette smoking, and diabetes. Symptoms of renal artery stenosis include high blood pressure that does not respond to treatment, severe high blood pressure in individuals younger than 30 or greater than 50 years of age. Renal artery stenosis is diagnosed with imaging and functional tests. Treatment for renal artery stenosis include medication or surgery.
Preeclampsia is related to increased blood pressure and protein in the mother's urine. Preeclampsia typically begins after the 20th week of pregnancy. When preeclampsia causes seizures, it is termed "eclampsia" and is the second leading cause of maternal death of in the US. Preeclampsia is the leading cause of fetal complications. Risk factors for preeclampsia include high blood pressure, obesity, multiple births, and women with preexisting medical conditions such as diabetes, kidney disease, rheumatoid arthritis, lupus, or scleroderma. Pregnancy planning and lifestyle changes may reduce the risk of preeclampsia during pregnancy.
A diabetic diet, or diabetes diet helps keep blood glucose levels in the target range for patients. Exercise and medication may also help stabilize blood glucose levels. Keeping track of when you take your diabetic medicine, keeping track of food choices, eating the proper amount of fruits, vegetables, carbohydrates, and fats will also help maintain proper blood glucose levels.
Diabetes-related foot problems can affect your health with two problems: diabetic neuropathy, where diabetes affects the nerves, and peripheral vascular disease, where diabetes affects the flow of blood. Common foot problems for people with diabetes include athlete's foot, fungal infection of nails, calluses, corns, blisters, bunions, dry skin, foot ulcers, hammertoes, ingrown toenails, and plantar warts.
Prader-Willi syndrome is a condition characterized by severe floppiness (hypotonia), poor growth, delayed development, and poor feeding problems in early infancy later followed in infancy by excessive eating that may lead to extreme obesity. The genitals in both females and males are underdeveloped and most are infertile. Prader-Willi syndrome is related to chromosome 15.
In the United States diabetes is the most common cause of kidney failure. High blood pressure and high levels of blood glucose increase the risk that a person with diabetes will eventually progress to kidney failure. Kidney disease in people with diabetes develops over the course of many years. albumin and eGFR are two key markers for kidney disease in people with diabetes. Controlling high blood pressure, blood pressure medications, a moderate protein diet, and compliant management of blood glucose can slow the progression of kidney disease. For those patients who's kidneys eventually fail, dialysis or kidney transplantation is the only option.
Managing your diabetes is important. The goal of diabetic therapy is to control blood glucose levels and prevent the complications of diabetes. Information about exercise, diet diet, and medication will help you manage your diabetes better. Blood glucose reagent strips, blood glucose meters, urine glucose tests, tests for urinary ketones, continuous glucose sensors, and Hemoglobin A1C testing information is also provided in this article.
Stroke is the third leading killer in the United States. Some of the warning signs of stroke include sudden confusion, trouble seeing with one or both eyes, dizziness, loss of balance, and more. Stroke prevention and reatable risk factors for stroke include lowering high blood pressure, quit smoking, heart disease, diabetes control and prevention.
The importance of a healthy lifestyle in disease prevention is widely understood and most people know that lifestyle changes and choices can be critical to good health. Yet, few practice healthy behaviors that constitute healthy living.
Cholesterol occurs naturally in the body. High blood cholesterol levels increase a person's risk of developing heart disease, heart attacks, strokes, TIAs, and more. In addition to medication (fibrates, statins, bile acid sequestrants, and niacin), lifestyle changes can be made to lower blood cholesterol levels
Disease prevention in women includes screening tests that are a basic part of prevention medicine. All screening tests
are commonly available through your general doctor. Some specialized tests may be available elsewhere.
