Patients with kidney stones can consume fried foods in small amounts. The formation of kidney stones is the result of a multi-factorial formation. A prolonged high-fat diet can increase the decrease of calcium excretion in the gastrointestinal tract, which causes an increase of calcium excretion in the urine. Moreover, a prolonged high-fat diet, fried food diet, etc., can cause sclerosis of the blood vessel walls and lead to related medical complications, and can also interfere with the normal electrolyte metabolism of the body. Therefore, after prolonged intake of large amounts, the probability of suffering from stone disease may increase. However, stone formation is not an overnight process, it is a long-term chronic process. As long as the amount of intake is not too much or not too much for a long time, occasional use of fried food or small intake of fried food will not increase the probability of kidney stones in principle. In principle, a daily intake of less than 50g does not significantly increase the probability of kidney stones. At the same time, there are various aspects of stone prevention in daily life, including drinking more water appropriately, regular medical checkups, regular work and rest, and many other situations.
