It is not recommended for organisms with kidney stones to eat fish gelatin because it is rich in collagen, iron, selenium, calcium, phosphorus and other substances. Although rich in nutritional value, it tends to promote the enlargement of kidney stones and the formation of new stones, because the formation of kidney stones has a great cause with dietary structure and lifestyle. If the diet is high in sugar, fat, animal protein, dairy products and other ingredients, it tends to increase the excretion of urinary calcium, urinary oxalic acid and uric acid, thus promoting the formation of stones. Once the stones are formed, we should take drugs to promote stone discharge or break them up by extracorporeal shock wave lithotripsy. If the stones are too large, they can be removed by minimally invasive surgery, and it is recommended that the body with kidney stones drink more water and urinate more in daily life to help the discharge of small stones and maintain the health of the urinary system.
