Researchers have found that patients with the metabolic syndrome tend to have highly acidic urine, which increases the risk of developing kidney stones.
The current findings indicate that people with the other components leading to the metabolic syndrome also have highly acidic urine. The association of highly acidic urine with elevated levels of systolic blood pressure, serum glucose, triglycerides, and lower levels of high-density lipoprotein-cholesterol (LDL-C)--all features of the metabolic syndrome--has not been previously reported.
In our study we found that most of the stones formed in normal acidic urine
pH were composed of mainly calcium oxalate as dominant component while in alkaline urine at pH 6 to 8 triple phosphate is the major stone component.
Although both groups had acidic urine
, differences in pH were not statistically significant.
"Our next step is to find out what causes type 2 diabetics to have an abnormally acidic urine, and what other urinary factors protect some diabetics who do not form uric acid stones," said Dr.
Obesity and a diet rich in animal protein are associated with abnormally acidic urine. In earlier studies, uric acid stones were associated with insulin resistance and type 2 diabetes (See Nutrition Health Review, Issue #88).
Precipitation of urates is often seen in acidic urine
The problem: All the protein that Atkins recommends leads to acidic urine
. (6) "And there's no dispute that an acid urine leaches calcium out of bones," says Blackburn.
As far as cranberry juice is concerned, it does tend to create an acidic urine
that may discourage or even kill some bacteria.
Urine analysis revealed bilirubinuria (+ ++), glucosuria (++), proteinuria (++), ketonuria (++++), isosthenuria and acidic urine
Reducing the magnesium in the diet and adjusting the diet to create an acidic urine
can prevent these struvite (magnesium-ammonium-phosphate) crystals from forming.
"Larger people have very acidic urine
even when they control their diets," said Dr.
A strongly acidic urine
may also result from accidental contamination of the collection vessel.
