Ayurveda and Blood Pressure
- Hits: 8235
This is the force developed by the blood against any unit area of the vessel wall. It is difficult to say exactly what is high blood pressure but an attempt has been made taking into account various facts such as age and sex of the patient.
|20 years||140/90 mm of Hg|
|40 years||160/95 mm of Hg|
|75 years||170/105 mm of Hg|
In Ayurveda, blood pressure is not considered a problem of the blood alone but is considered in conjunction with the rasas.
There is no factor responsible for high blood pressure. As is basic in Ayurveda all factors within the 13 parameters – the three doshas, the seven tissues and the three waste products are taken into consideration, while treating the disease.
The various factors are diet and character of the patient which are likely to affect those with high blood pressure complaints.
Aahar (Diet): Excess consumption of alcohol, salt, bitter, sour, root vegetables, greens, fish.
Vihar: Diwaswap (daytime naps), anger, hard work.
- Manas – Anger, temper.
- Kaal (period) – Sharad (autumn).
- Guyton’s physiology.
When there is excess salt in the body, the osmosity increases and this in turn stimulates the thirst center, making the person drink extra amounts of water to dilute the extra cellular salt to a normal concentration. This obviously increases the extra cellular fluid volume.
The increase in osmosity in the extra cellular fluid also stimulates the hypothalamus and the posterior pituitary secretary mechanism, to secrete increased quantities of any diuretic hormone. This hormone in turn causes the kidneys to reabsorb greatly increased quantities of water from the renal tubular fluid before it is excreted as urine, thereby diminishing the volume of urine while increasing the extra cellular volume.
This accumulation of small amount of extra salt in the body can lead to considerable elevation of the arterial pressure. How increased fluid volume elevates the arterial pressure is the role of auto regulation.
- Increased extra cellular fluid volume.
- Increased blood volume.
- Increased mean circulatory filling pressure.
- Increased venous return of blood to the heart.
- Increased cardiac output.
- Auto regulation.
