Urine pH is used to classify urine as either a dilute acid or base solution. Seven is the point of neutrality on the pH scale. The lower the pH, the greater the acidity of a solution; the higher the pH, the greater the alkalinity. The glomerular filtrate of blood is usually acidified by the kidneys from a pH of approximately 7.4 to a pH of about 6 in the urine. Depending on the person's acid-base status, the pH of urine may range from 4.5 to 8. The kidneys maintain normal acid-base balance primarily through the reabsorption of sodium and the tubular secretion of hydrogen and ammonium ions. Urine becomes increasingly acidic as the amount of sodium and excess acid retained by the body increases. Alkaline urine, usually containing bicarbonate-carbonic acid buffer, is normally excreted when there is an excess of base or alkali in the body. Secretion of an acid or alkaline urine by the kidneys is one of the most important mechanisms the body uses to maintain a constant body pH.
A highly acidic urine pH occurs in:
Starvation and dehydration
Respiratory diseases in which carbon dioxide retention occurs and acidosis develops.
A highly alkaline urine occurs in:
Urinary tract obstruction
Renal tubular acidosis
Chronic renal failure
Respiratory diseases that involve hyperventilation (blowing off carbon dioxide and the development of alkalosis)
When a body is healthy, the pH of blood is 7.4, the pH of spinal fluid is 7.4, and the pH of saliva is 7.4. The pH of saliva parallels the extra cellular fluid and as such is an improtant and easy tool for analysis.
Virtually all degenerative diseases, including cancer, heart disease, osteoporosis, arthritis, kidney and gall stones, and tooth decay are associated with excess acidity in the body. While the body does have a homeostatic mechanism which maintains a constant pH 7.4 in the blood, this mechanism works by depositing and withdrawing acid and alkaline minerals from other locations including the bones, soft tissues, body fluids and saliva. Therefore, the pH of these other tissues can fluctuate greatly. The pH of saliva offers us a window through which we can see the overall pH balance in our bodies.
Cancer cannot exist in an alkaline environment. All forms of arthritis are associated with excess acidity. Acid in the body dissolves both teeth and bones. Whatever health situation you are faced with, you can monitor your progress toward a proper acid/alkaline balance by testing your saliva pH.
