Diabetes

Tuesday, March 9th, 2010

Diabetes, a disease in which the amount of glucose (sugar) in the blood is too high, has an effect on cardiovascular health.

If you have diabetes, your pancreas, the organ in your body responsible for producing insulin, is defective in producing or adequately utilizing insulin…or both, which leads to elevated blood sugar levels.

Insulin is vital for converting sugars into fuel so your body can function properly. When these sugars are not turned into energy, your body responds by creating more glucose from stored fats. Over time, these sugars accumulate in the bloodstream. If the condition is left untreated, it can cause very serious complications such as kidney, eye, and nerve damage and heart and vascular disease.

The two main types of diabetes are:

  • Type I (also called juvenile diabetes) develops in children and young adults. In Type I Diabetes, the body does not produce enough or any insulin. Cells in the pancreas responsible for this function have been destroyed.
  • Type II (also called adult-onset diabetes) is the most common form of diabetes, affecting roughly 16 million Americans. In Type II Diabetes, the body cannot produce enough insulin, or the insulin produced is ignored by the body. This condition develops in usually older, overweight people.

There is no cure for diabetes, but many treatments are available for diabetics which enable them to lead long and healthy lives. It is important to follow your doctor’s treatment plan precisely, as this can add many “quality” years to your life.

What are the warning signs and symptoms of diabetes?
The warning signs of diabetes, both Type I and Type II, are similar. The main difference is that Type I Diabetes usually develops much more quickly. It is important to be aware of the symptoms of diabetes because early detection and treatment is the best way to avoid permanent complications.

If you have any of the symptoms below, contact your Primary Care Physician immediately:

  • Sweet, fruity breath (also called “acetone breath”)
  • Increased thirst
  • Fatigue
  • Weight loss
  • Excessive trips to the bathroom to urinate, especially at night
  • Blurred vision

How is diabetes detected?
Diabetes is diagnosed by a blood test. Your doctor will order a lipid profile, which examines your cholesterol and your glucose levels. If your glucose levels are high, it is an indicator that you may have diabetes. Diabetes can also be diagnosed by a simple urine test which shows the presence of glucose in the urine.

What are the treatment options for diabetes?
The key is to keep your sugar levels within your target range by maintaining a healthy lifestyle and by using insulin injections. Your physician will determine your target range.

Type I diabetics must be treated with insulin injections because the body is unable to produce insulin on its own. Two to four insulin injections are required daily.

For all diabetics, lifestyle changes are a must. This includes stopping smoking, exercising regularly, eating a balanced diet (low in carbohydrates, fat and sugars), and maintaining a healthy weight, cholesterol level and blood pressure level. It is important that all people lead a healthy lifestyle. However, it is especially important if you are a diabetic. Why? Because all of these risk factors compound the severity of diabetes.

Renal artery ultrasound

Monitoring the arteries that carry blood to your kidneys.

Your doctor may order a renal artery ultrasound if you have early signs of kidney failure or if your blood pressure is difficult to control despite multiple medications. Renal artery ultrasound uses ultrasound waves to make an image of the arteries.  This test can help your doctors diagnose if your kidney vessels are blocked, which can affect your blood pressure and kidney function. You may also have your kidney tissue imaged to help determine the size and shape of your kidneys. Kidney size and function can often be affected in people with high blood pressure or diabetes.

What happens during a renal artery ultrasound?
You will be asked to lie down on an examination table. The technician (or physician) will place a clear gel on your abdomen. The gel is simply a lubricant that allows the transducer (a device that both puts out and detects ultrasound signals) to slide around easily on your skin. When the transducer is placed against the skin, an image of the artery is shown on a video screen. The renal arteries are identified and a measurement will be made of the speed of blood flow through the artery.

What are the risks of renal artery ultrasound?
Since the procedure is done without entering the body and does not use dyes or x-rays, there is no known risk or pain involved in having a renal artery ultrasound.

How does a renal artery ultrasound work?
The transducer (ultrasound probe) emits high-frequency ultrasound waves that pass into the body and bounce back to the transducer. The sound waves are reflected differently by different parts of the body. The transducer detects the different reflections of the sound waves, which are then measured and converted by a computer into live pictures of the artery.
