Patient's question:
Etiology or causes of onset:Doctor's answer:
Avoidance: This mainly includes three aspects: limiting foods high in oxalates, animal protein foods, and high-salt foods.1. Limit intake of foods high in oxalates: Most oxalates in urine come from the body's metabolism, while a small portion comes from food. However, it is still important to reduce the absorption of oxalates in the intestines and avoid consuming foods rich in oxalates, such as chocolate and coffee.
2. Control intake of animal protein foods: Excessive intake of animal protein can increase the excretion of oxalates and calcium in the urine, reduce the excretion of citrate, lower urine pH, and thus increase the risk of kidney stone formation. Therefore, it is important to control the excessive intake of animal protein in the diet.
3. Avoid high-salt foods: High-salt foods can increase urinary calcium levels while reducing the excretion of citrate, thereby increasing the incidence of kidney stones. Therefore, in daily meals, use less salt during cooking, eat less pickled vegetables, cured meats, and fried foods to maintain a light diet. At the same time, drink more water to prevent the occurrence and recurrence of kidney stones.
