Life details are the key to stone prevention and control, and perseverance is the only way to achieve results. 1. Drinking water guidance Generally, the risk of stone formation will increase if the daily urine volume is below 1 liter, while the risk is lower if it is above 2 liters. To ensure a daily urine volume of 2 liters or more, it is recommended to consume more than 2000 ml of water daily in addition to diet. 2. Dietary guidelines for stone patients 1. Limit excessive consumption of animal protein 2. Recommend a certain amount of calcium intake (600-800 mg/day) 3. Limit excessive oxalic acid intake Plant foods often contain high amounts of oxalic acid. Therefore, it is necessary to control the excessive intake of oxalic acid-rich foods, such as spinach, bamboo shoots, chocolate, black tea. Oxalic acid itself is soluble and can be removed from the juice by boiling, so it is recommended that foods with high oxalic acid content be boiled and consumed. 4, limit the excessive intake of salt (10g/day or less) Excessive intake of sodium will not only cause urinary sodium, but also increase the excretion of calcium in the urine. Japanese salt intake should be guided by the standard of dissatisfaction (10g/day). 5, the intake of carbohydrates (recommended consumption of cereals, limit excessive consumption of sugar) cereals are rich in magnesium and dietary fiber. It is now believed that the magnesium in the urine is one of the factors that prevent the formation of stones. Magnesium in the intestine can also be combined with oxalic acid, prevent the absorption of oxalic acid, therefore, the intake of magnesium can play a role in inhibiting the role of urinary stones. 6.Limit the excessive intake of fat 7.Recommended intake of moderate amount of citric acid: citrus in citric acid content is relatively high, can be moderate consumption. 8, dietary life guidance Therefore, it is very important to maintain a balanced breakfast, lunch and dinner. In addition, it is also important to keep a balanced diet from dinner to bedtime, because the amount of substances conducive to stone formation in the urine increases within 2 to 4 hours after meals. 9, drink less sugar and alcoholic beverages because sugar can promote the intestinal absorption of calcium, and accordingly also increase the absorption of oxalic acid. Drinking alcohol can increase urinary uric acid excretion and reduce urine volume, although beer can be a temporary diuretic, but then will cause urine concentration, long-term drinking makes high calcium urine, high phosphate urine becomes more prominent, conducive to stone formation.
