People should pay attention to diet-related diseases in life, we think of a lot of them, but have you ever thought about the occurrence of urethral stones, understanding the general knowledge of urethral stones, so as to help the recovery of urethral stone patients, understand the danger of urethral stones, but also pay attention to diet. So, what dietary matters should patients with urinary stones pay attention to? 1, drink more water not to hold urine. Do not hold urine, drink more urine to help bacteria, carcinogenic substances and easy to stone material quickly out of the body, to reduce the chance of kidney and bladder damage. 2, eat less salt. Too salty diet will increase the workload of the kidneys, and salt and calcium have a synergistic effect in the body, and can interfere with the metabolic process of drugs for the prevention and treatment of kidney stones. The daily intake of salt should be less than 5 grams. 3, drink less beer. Some people believe that beer can be diuretic, can prevent the occurrence of urethral stones. In fact, the wort of beer contains calcium, oxalic acid, uric acid and purine nucleotides and other acidic substances, they are used in each other, can make the body’s uric acid increased, becoming an important cause of kidney stones. 4, meat animal offal to eat less. Control the intake of meat and animal offal, because the metabolism of meat produces uric acid, animal offal is a high purine food, decomposition and metabolism will also produce high blood uric acid, and uric acid is the formation of urinary tract stones components. Therefore, the daily diet should be mainly vegetarian, eat more fiber-rich food. 5, careful eating spinach. According to statistics, more than 90% of urethral stones contain calcium, while calcium oxalate stones account for about 87.5%. If the amount of oxalate intake in food is too much, the urine calcium oxalate and in a supersaturated state, excess calcium oxalate crystals may be precipitated from the urine and form stones. In the food, the highest oxalate is spinach, and spinach is one of the vegetables that people often eat. 6, do not drink milk before going to bed. As the milk contains more calcium, and most of the urethral stones contain calcium salts. The most dangerous factor in the formation of urethral stones is the sudden increase of calcium concentration in the urine for a short time. 2~3 hours after drinking milk, it is the peak of calcium elimination through the kidneys, so when you are in a sleep state, urine concentration, calcium through the kidneys more, so easy to form stones. 7, should not eat more sugar. After taking sugar, the concentration of calcium ions in the urine, oxalic acid and urine acidity will increase, the increase in urine acidity, calcium urate, calcium oxalate easy to precipitate, prompting the formation of urethral stones.
