Natural Remedies for Kidney Stones
Nephrolithiasis is a disorder in which small stones - usually formed from calcium and ox-alate - precipitate in the kidney. If they pass into the ureter they cause irritation, spasm, and may block the flow of urine. The pain of a kidney stone is intense it typically starts suddenly in the lower back and radiates down and around toward the groin. In general, the more calcium and oxalate in the urine, the greater the chances of developing kidney stones. Uric acid in the urine can be the seed around which calcium oxalate stones develop. The risk of kidney stones can be strongly influenced by dietary factors.5
if you can get kidney stones by drinking milk That's a common myth. Research doesn't support this mis-perception. In fact, drinking milk may reduce the risk. A high-calcium diet may decrease the absorption of oxalate, a substance in some plant-based foods that can form calcium oxalate kidney stones. . . . if phytoestrogens in soybeans protect your bones Maybe, since they act much like mild estrogens in the body. After menopause, as natural estrogen declines, phytoestrogens in soy products may help prevent bone some loss. See What's 'Soy' Good in chapter 11.
The molecule adenosine triphosphate (ATP) provides the energy that directly powers muscle contraction. Logic would have us believe that if we provide the building blocks of ATP in supplements, muscle cells would have more ATP available and exercise performance would be enhanced. The adenosine in ATP can be made from the molecule inosine. However, adenosine concentrations in the cells seem to be tightly controlled and supplemented inosine is not efficiently converted to adeno-sine. Furthermore, it has been suggested that the processes necessary to break down the excessive inosine may generate free radicals. In addition, inosine is broken down to uric acid, which is involved in the formation of certain types of kidney stones and gout if not proficiently removed from the blood
Other direct or indirect effects of alcohol abuse include impaired drug metabolism and elevated blood uric acid levels. The latter can lead to gout and kidney stones. Barbiturates, which are sedative drugs (pen-tothal, pentobarbital, seconal), are metabolized and inactivated by one of the same mechanisms that metabolizes alcohol. Since the metabolism of alcohol is given higher priority than the inactivation of barbiturates, these drugs stay active longer and build up in the body. Barbiturates depress the CNS, breathing, and heart activity. Therefore, combining barbiturates with alcohol can be a lethal combination.
In healthy adults, oral intakes of calcium up to 2 g per day do not have significant side effects or toxicity. People with hyperparathyroidism and people who form calcium-oxalate kidney stones should avoid high intakes of calcium. In healthy adults, high intakes of calcium do not appear to increase the risk of kidney stones.
The body uses calcium to convert the poisonous liquid phosphoric acid in colas into the more stable solid phosphates, for example.22 But these phosphates may form into calcified kidney stones, or calcium deposits (which can also result from a urinary infection, inherited metabolic disorders, and other causes23). Many people erroneously think kidney stones are caused by excessive calcium. But the real culprit may be the high level of phosphoric acid, which happens to be a primary ingredient of colas. Anyone with a concern about kidney stones should avoid colas.
Levels of vitamin C in urine can mask the results of tests for diabetes. Very large doses may cause kidney stones and or diarrhea, and for those with iron overload (hemochromatosis), excessive vitamin C (which enhances iron absorption) can make the problem worse. But the effects of taking large amounts for a long time isn't known. A Tolerable Upper Intake Level (UL) for vitamin C has been set 2,000 milligrams daily for adults 1,800 milligrams daily for teens ages fourteen to eighteen.
Multivitamins or single-nutrient supplements to get your water-soluble vitamins, moderation is advised (see Supplement Sense, page 38), because high doses of several of the B vitamins can have harmful effects, and high doses of vitamin C may contribute to the formation of kidney stones.
Cocoa and consequently chocolate are rich in oxalic acid. In the presence of oxalic acid or its anion oxalate, calcium easily forms water-insoluble calcium oxalate, which can form into renal calculi or kidney stones in predisposed individuals (9). Cocoa was found to contain 0.721.18 oxalic acid on a fat-free basis (6). Kasidas and Rose (10) determined the oxalate content of common foods and found high levels in rhubarb, spinach, tea, beetroot (beets), peanuts, chocolate and parsley in approximate descending concentration.
Based on this it is possible for people to exceed the AI. Although the efficiency of calcium absorption decreases as more is ingested and body calcium status is optimal, this can still lead to increased entry of calcium into the body. The Upper Limit (UL) has been set at 2,500 milligrams for children and adults, a level that is usually only achieved with the assistance of supplementation. Beyond this intake level the risk of undesirable effects increases, and can include loss of appetite, nausea, vomiting, constipation, abdominal pain, dry mouth, thirst, and frequent urination. In addition, since most forms of kidney stones are calcium oxalate, higher levels of calcium in the urine can increase the risk of kidney stones in people prone to them. Very high intakes of calcium from supplements and usually in combination with calcium-containing antacids, over time, can lead to increased calcium content in tissues such as muscle (including our heart), blood vessels,...
A varied diet based on plant proteins is adequate, yielding growth and body maintenance results equivalent to a diet based on meat protein.39 The lower incidence of obesity, constipation, lung cancer, hypertension, coronary artery disease, type 2 diabetes, gallstones, reduced risk of breast cancer, diverticular disease, colon cancer, calcium kidney stones, and osteoporosis appear to be obvious advantages particularly of the well balanced vegan diet for the elderly.3,39,40 Key et al.,40 (Table 11.1) show the protective effect of daily fresh fruit intake in ischemic heart disease, cerebrovascular disease, and lung cancer, and daily raw salad protection for ischemic heart disease. They also presented a higher incidence of breast cancer in the vegetarian women, but the confidence interval was broad. The smokers in their study population demonstrated a higher rate of ischemic heart disease, cerebrovascular disease, and, of course, lung cancer, to emphasize the disease problems associated...
In several large studies in which 5-10 g of vitamin C were given daily to healthy humans for several years, no adverse effects were demonstrated, other than occasional nausea, loose stools, and diarrhea.1617 Although reports have warned of an increased risk of kidney stones with high intakes of vitamin C (oxalate is a metabolite of ascorbic acid), large doses of vitamin C do not increase oxalate excretion into the urine and do not contribute to kidney stones in healthy people.6 However, in pa tients with a history of kidney stones high doses of vitamin C should be taken only under their doctor's supervision. There is no evidence to support contentions that high doses of vitamin C can cause conditioned scurvy.17 High doses of vitamin C may decrease copper absorption, and chewable forms of vitamin C, because of their acidity, can cause erosion of dental enamel.17
Individuals with a tendency to form kidney stones can reduce the risk by 4 Reducing caffeine intake, as high intakes increase calcium excretion into the urine and may promote stone formation. Heavy alcohol consumption also increases the chance of developing kidney stones. Because vitamin C can be metabolized to oxalate, it has been suggested that high intakes of vitamin C might increase risk of kidney stones. However, oxalate in the urine generally does not increase unless the daily dose of vitamin C is greater than 6 g, and even then only rarely. In individuals susceptible to stone formation who are taking high doses of vitamin C, supplemental vitamin B6 and magnesium can reduce risk of increased oxalate in the urine.
Because of molybdenum's widespread availability in the human diet, a deficiency is somewhat unlikely. However, people receiving intravenous (IV) feedings for several months are at risk. In contrast, molybdenum is fairly nontoxic. Molybdenum is involved in the breakdown of purines to a waste product called uric acid. Uric acid is removed from the body in urine, and theoretically there is a greater risk for developing kidney stones formed by excessive uric acid. Excessive uric acid production may also increase the risk of developing gout, which is characterized by recurrent inflammation of joint regions and deposition of uric acid in those areas.
Bone loss, especially in the legs, is significant during spaceflight. This is most important on flights longer than thirty days, because the amount of bone lost increases as the length of time in space increases. Weightlessness also increases excretion of calcium in the urine and the risk of forming kidney stones. Both of these conditions are related to bone loss. Sodium intake is also a concern during spaceflight, because space diets tend to have relatively high amounts of sodium. Increased dietary sodium is associated with increased amounts of calcium in the urine and may relate to the increased risk of kidney stones. The potential effect of these and other nutrients on the maintenance of bone health during spaceflight highlights the importance of optimal dietary intake.
Osteoporosis is a bone disorder in which bone strength is compromised, leading to an increased risk of fracture. Along with other lifestyle factors, intake of calcium and vitamin D plays an important role in the maintenance of bone health and the prevention and treatment of osteoporosis. Good calcium nutrition, along with low salt and high potassium intake, has been linked to prevention of hypertension and kidney stones.
