Blood Pressure, When it Rises...

Dr. Nidhi Luthra

The cure for high blood pressure is much more about prevention and control than cure. Changes in life-style- diet, regular exercise are a must to prevent and keep a check over rising blood pressure. Since, the treatment for high blood pressure is more at promotion of health, homoeopathic system of medicine forms a very important mode of treatment for this problem.


Blood pressure is the sideways pressure exerted on the walls of the artery by the force of the heart beat. The heart is a muscular pump and its function is to pump 57-85gm of blood in each beat about 70 times a minute throughout day and night. When the heart contracts and fresh blood is pumped into the arteries, the pressure is at its peak and is called the systolic pressure. When the heart relaxes and gets filled with fresh blood, the pressure is at its lowest and is called the diastolic pressure. The body has a complex system by which the blood pressure is regulated and controlled. The kidneys, suprarenals, brain and nervous system play a major role in regulating blood pressure. The normal range of blood pressure is 110/70 to 140/90 mm Hg depending upon the age of the person.

Hypertension is a condition that occurs when the pressure of blood in the arteries is persistently higher than normal for a person's age because of increased resistance to blood flow through the arterial circulation. This resistance results from narrowing of arteries or reduced elasticity of their walls. The large arteries become more and more rigid with ageing but the rate and extent of this change vary greatly between individuals.

A disorder characterized by high blood pressure; generally this includes systolic blood pressure (the "top" number, which represents the pressure generated when the heart beats) consistently higher than 140, or diastolic blood pressure (the "bottom" number, which represents the pressure in the vessels when the heart is at rest) consistently over 90.

Hypertension puts a strain on the left ventricle because greater pumping force is needed to push blood around the body through the arteries. The muscle of the left ventricular wall thickens to cope with the task. This is called left ventricular hypertrophy. The walls of the arteries gradually become damaged by the increased pressure within them.

Causes, Incidence, and Risk Factors
Blood pressure is determined by the amount of blood pumped by the heart, and the size and condition of the arteries. Many other factors can affect blood pressure, including volume of water in the body; salt content of the body; condition of the kidneys, nervous system, or blood vessels; and levels of various hormones in the body. Caucasian men and African-Americans of both s*x*s have a higher incidence of significant hypertension.

"Essential" hypertension has no identifiable cause. It develops gradually in adults in whom there is no single reason for the increased pressure. It is thought that one's heredity may affect the circulation and contribute to essential hypertension. It is more common in men and the risk is increased by obesity, smoking, high salt intake, excessive alcohol consumption, emotional stress and a sedentary life-style. Essential hypertension comprises over 95% of all hypertension.

"Secondary" hypertension is hypertension caused by another disorder. This may include:

  • Adrenal gland tumors
  • Cushing's syndrome
  • Kidney disorders
  • Glomerulonephritis
  • Renal vein thrombosis
  • Renal artery occlusion (renal artery stenosis)
  • Renal artery embolism
  • Renal failure
  • Use of medications, drugs, or other chemicals
  • Pregnancy or use of ora* *******tives
  • Hemolytic-uremic syndrome
  • Henoch-Schonlein purpura
  • Periarteritis nodosa
  • Radiation enteritis
  • Retroperitoneal fibrosis
  • Wilms' tumor
