Metabolic syndrome, (obesity, hypertension, dyslipidemia and hyperglycemia AKA diabetes), remains a concern in regards to increasing health risk within the United States population.  For the first time in recorded history, our current generation is projected to have a shorter life expectancy than the prior generation.  This is a projection from the New England Journal of Medicine in 2005 based on the current epidemic.  And things have only gotten worse since then.  Metabolic syndrome with its associated cardiovascular disease, stroke, blindness, amputations, etc., accounts for the majority of healthcare dollars currently being spent.  Still worse, current medical treatments focus only on symptoms, which actually make the syndrome worse.  Hyperinsulinemia causes the pancreas to secrete increased amounts of insulin in response to elevated blood glucose.  However, practitioners typically focus on glucose levels or hemoglobin A1c, and prescribe drugs which actually increase insulin levels even further.  In a typical case, a patient would present with obesity, hypertension, diabetes and elevated blood lipids.  The patient would be told to lose weight by eating more fruits and vegetables and to cut down on fats and cholesterol and to do some light exercise as a standard first-line therapy of lifestyle changes.  This certainly stands the test of reason.  The problem is that under this regimen, the syndrome actually worsens.  Eventually antihypertensive medication is prescribed as are drugs for diabetes.  Soon the patient finds themselves on 6 or more drugs with no improvement in their status.  The underlying problem is that nothing has been done to address their insulin resistance.  A more appropriate course of treatment in this scenario would be the use of a muscle sparing protein diet and more importantly carbohydrate restriction, consisting mainly of fiber and vegetables, keeping in mind that all carbohydrate, with the exception of fiber, will eventually be turned into blood glucose either quickly or slowly.  By restricted carbohydrate intake, insulin secretion can be reduced and thus reducing insulin sensitivity/resistance.  In doing this, weight loss can occur and the patient’s syndrome can actually reverse.  If you suffer from any of the symptoms associated with metabolic syndrome, you should consult with myself and/or your family physician before undertaking any therapeutic regimen as in extreme cases drug therapies may be appropriate to reduce risk of stroke and/or other consequential risks.

Each week I see patients who have recently been examined by their primary doctors and are told that have findings of high blood pressure, elevated blood sugar or both. They are ill advised to return for followup in 8 weeks for a second test. I am not suggesting that it is wrong to followup when you have such finings. It is however foolish to make no management recommendations and expect a different outcome on a subsequent visit. Often on the next visit medication will be prescribed as now there is a trend and not just a single visit finding which may have been just coincidence. It is necessary to show a trend vs. a single visit reading to prescribe drug therapies unless hypertension is severe. It is reasonable that if someone is found to have high blood pressure, or, blood work reflects elevation in blood glucose, that rather than simply recording such data for record keeping that lifestyle modifications would be immediately discussed and proposed as being not only appropriate but necessary. Again, it could be argued that simply having an elevation in blood glucose does not mean that you are diabetic. Currently the diagnosis of diabetes is based on a blood test called the Hemoglobin A1c. However, if your blood test is demonstrating elevation in glucose, you are currently in a prediabetic state that needs to be addressed, not just monitored until such point that you definitely have diabetes, as is the case with an enormous number of Americans. If you have either elevated blood glucose or high blood pressure there are definitive lifestyle changes that you need to be making, now, not later. These changes do not merely mean kicking back and awaiting a drug therapy. It is this combination of blood glucose elevation and hypertension that constitutes the metabolic syndrome, a leading cause of disabilities, stroke, heart disease and death in this country, and it is getting worse each year despite drug therapies. When I meet with my patients I routinely discuss all aspects of their health. Most patients come to see me for dizziness and balance problems as well as other brain based disorders, but this doesn’t mean that I can’t help them get their life back if they are dangerously hypertense or prediabetic. In fact, I believe it is my job.

High blood pressure affects about 1 in 4 American adults and is one of the most common worldwide diseases afflicting humans.  It increases the risk of heart disease and stroke for those afflicted, so it’s important to know how to lower high blood pressure. High blood pressure, aka hypertension risk factors include obesity, drinking too much alcohol, smoking, and family history of hypertension.  Hypertension is the most important modifiable risk factor for coronary heart disease (the leading cause of death in North America), stroke (the third leading cause), congestive heart failure, end-stage renal disease, and peripheral vascular disease.

Normal blood pressure with respect to cardiovascular risk is less than 120/80 mm Hg, (however, unusually low readings should be evaluated for clinical significance as well).  Prehypertension is a new category emphasizing that patients with prehypertension are at risk for progression to hypertension and that lifestyle modifications are important preventive strategies.  Home blood pressure predicts cardiovascular events much better than do office readings and can be a useful clinical tool. Anyone with hypertension should be monitoring their own BP at home.  BP kits are available everywhere, and they are inexpensive.  If your BP readings suddenly become low, you should tell your doctor to titrate downwards your medication so that you do not become syncopal, (passing out).  The following are the ranges of BP:

Normal – Systolic, (top number) lower than 120, diastolic, (bottom number) lower than 80.

Prehypertension – Systolic 120-139, diastolic 80-99.

Stage 1 hypertension- Systolic 140-159, diastolic 90-99.

Stage 2 hypertension- Systolic equal to or more than 160, diastolic equal to or more than 100

Recommendations to lower blood pressure and thus decrease cardiovascular disease risk include the following:

  • Lose weight if overweight. Even a few extra pounds will raise blood pressure.
  • Google DASH (Dietary Approaches to Stop Hypertension) for a reasonable diet, which is rich in fruits and vegetables.
  • Limit alcohol intake to no more than 1-2 drinks/day.
  • Increase aerobic activity (30-45 min most days of the week).
  • Reduce sodium intake, learn to read nutritional information labels on products you purchase.
  • Maintain adequate intake of dietary potassium, calcium and magnesium for general health.
  • Stop smoking and reduce intake of dietary saturated fat and cholesterol for overall cardiovascular health.
