HEART DISEASE: ORIGINS OF DISEASE – LIQUIDS
The composition of the blood, and its associated bodily fluids, is controlled by the kidneys, adrenals, liver and — to some extent — lungs and skin. The pressures are influenced by the heart, hormones, the vaso-motor nerves in the walls of the blood-vessels and by the volume of liquid drunk. The two functions overlap and interlink; what affects composition affects pressure, and vice versa.
Liquids are not all in liquid form when consumed, and even the driest 'solid' foods contain appreciable amounts of water, either in a form which can be squeezed out, or as compounds from which the water is liberated by combustion. Whether absorbed from stomach and intestine, or chemically released within the tissues, this fluid goes to increase the bulk of the blood. At the same time, wastes produced by life-processes are collected by the blood from organs and tissues. The increased volume of fluid and the tissue-wastes must be extracted, and this task falls mainly upon the kidneys. The separated-off fluid is urine.
If the kidneys do not function adequately, toxic materials and excess fluid remain in circulation. The walls of the arteries suffer, as do the heart itself and the nerves which control its action. Persistent irritation leads to a chronic inflammation and eventually to microscopic scarring of the surfaces exposed to the blood-flow; hardening of the arteries and weakening or distortion of the heart-valves are logical consequences.
The kidneys themselves depend upon a vigorous flow of reasonably healthy blood through them to sustain their function. Increased pressure or unduly charged blood cause obstruction and poor functioning. This means that overworked and under-supported kidneys are potentially liable to develop a vicious cycle. In everyday terms, any excess of fluid taken in, or any serious deficiency or gross excess in dietary, has an immediate and depressing effect upon kidney efficiency. Clean blood, not thickened by such common errors as copious drinking and the over-consumption of starchy foods, flows freely and is easily kept in sweet condition. But sticky blood — which Lindlahr called 'colloid', and which may be likened to the glutinous result of adding water to starch — is a menace.
The link between adequate kidney function and normal heart action should now be evident, and this supports James C. Thomson's claim that probably every serious heart condition has been preceded by some disturbance of the circulation through the kidneys.
When the kidneys cannot meet the body's needs not only the heart suffers. Skin, lungs and liver all come in for increased burdens. This is why excessive perspiration and bronchial distress commonly accompany kidney weakness. The discomfort of the liver may be less superficially obvious, but it has to work more intensively upon the wastes within the blood, in the attempt to render them less toxic, or to make them capable of being eliminated in other ways. No organ is an island ....
