Overcoming Renovascular Hypertension


In an issue of HR magazine, there appears a health article by Dr. R.D. Gordon of the University of  Queensland medical unit in Australia that hypertension – a disabling and potentially dangerous condition – can be treated successfully without drugs if the cause can be pinpointed.

One kind of hypertension is that arising from insufficient blood reaching a kidney.  This is called renovascular hypertension.  It is a kind of hypertension where precise diagnosis could be difficult.  A diagnostic procedure where there is no need to suspend medication has been developed. 

A research project aims at establishing the link between the blood pressure and the sympathetic nervous system.  It involves the investigation of the behavior of circulating adrenaline as a modulator of the sympathetic nervous system activity.  The adrenaline, according to Dr. Gordon, is actually the so-called stress hormone which is believed to bring hypertension by causing the arteries to contract in response to stress.

Dr. Gordon’s theory is that adrenaline may work by modulating the release of non-adrenaline, another hormone which directly controls blood pressure.  This hormone comes from nerve endings in many areas of the body, many of which are adjacent to major arteries.  Dr. Gordon suspects that the action of this hormone might be affected by minute traces of adrenaline flowing loosely in the bloodstream.

In conducting this experiment, Dr. Gordon measured the minute quantities of adrenaline and non-adrenaline in the blood of a patient.  The patient is then required to perform isometric (a method of physical exercise in which one set of muscles is tensed, for a period of seconds, in opposition to another set of muscles or to an immovable object) like the raising of the legs stiffly for several times in a day. These isometric exercises, according to Dr. Gordon, was a stimulus for sympathetic nervous system activity.

Slimmer is Healthier.  Most people don’t realize all the health advantages of being slender.  Research shows that people who are from 20 percent or more above recommended weight are more likely to die from heart, circulatory and kidney diseases, cancer, diabetes, digestive disorder, and even accidents.

Thinner people, on the contrary, have a lower risk of trouble from strokes, liver cirrhosis, appendicitis, intestinal obstructions and hernia.

Tidbits. Geriatrics, the study of aging, teaches many conflicting theories, one of the most exciting revolving around the eventual possibility of inserting genes in the DNA, reprogramming their present commands to die within what is called the normal life span.
