The main reason for the high incidence of kidney stone disease in summer is sweat and water. The hot weather in summer makes the body sweat a lot and the water in the body is discharged through sweat, which makes the urine concentrated accordingly. If the water lost in the body is not replenished in time, the salts that form crystals in the urine will be supersaturated and crystals will be deposited in the urine and stones will be formed. The higher the concentration of urine, the greater the risk of stones. Some people think that drinking more beverages or hiding in air-conditioned rooms to reduce sweating and hydration can reduce the incidence of kidney stones. This is not the case. It is understood that currently, college students have become the main group of people suffering from kidney stones. The reason for this is that a large proportion of them drink beverages for a long time, or even use beverages instead of plain water, resulting in an increase in the concentration of calcium ions in the urine, oxalic acid content and acidity of the urine, the mixture of which greatly increases the risk of stone development. And hiding in an air-conditioned room is also not helpful. Experts say that less sweating does not mean no water loss, air conditioning rooms are generally dry, water is not discharged through sweat but evaporated directly from the skin surface, which will also cause urine concentration. Cause three, minerals, oxalic acid excess In addition, excessive intake of animal offal, spinach and other mineral and oxalic acid-rich diet, also prone to the formation of urinary stones. Therefore, the most important preventive measure is to increase the intake of water. In addition, often stay up late and go to nightclubs, which affect the detoxification of the kidneys, so that the body excess of these substances precipitated in the kidneys; or beer, barbecue, seafood, meat as a night snack, resulting in the body intake of large amounts of uric acid, purine, long-term may lead to kidney system stones. This is also the main reason why the emergency room often sees kidney stone patients in summer. Drinking more water when you have kidney stones seems to have become the rule of thumb for many old patients. Some studies have shown that increasing the amount of urine by 50% can reduce the incidence of kidney stones by 86%. If you can drink a full 2000 to 3000 ml of water every day and maintain a urine volume of about 2000 ml, it is the easiest and most effective way to prevent kidney stones. However, the urologist would like to remind you that the method of drinking water to help drain kidney stones is not applicable to all patients. Because kidney stones patients should drink more water or not, depending on the size of the stones. Patients with small stones can drink more water to increase the volume of urine, to promote the discharge of small stones, while diluting the urine to prevent the formation of stones, and can slow down the growth of stones. Especially in summer, the human body is generally prone to sweating, so drinking more water can prevent crystal precipitation due to the accelerated evaporation of water in the body, which has a better effect on the prevention of stone formation. However, when the stone diameter exceeds 1 cm, and causes greater pressure on the urinary system, and even causes the patient’s hydronephrosis, you should not blindly drink more water. Otherwise, the increased urine volume will aggravate the obstruction of the urinary system and intensify the hydronephrosis, and the consequences will be more serious. In this case, it is recommended that patients should undergo early surgical stone extraction or extracorporeal lithotripsy treatment.
