1, milk, chocolate, citrus, orange. American scholars on the causes of pediatric enuresis after an in-depth study, the diet of milk, chocolate and citrus fruits in excess, is the main cause of nighttime enuresis in children, including milk in excess caused by the enuresis up to 60%. As soon as the above-mentioned foods are stopped, the enuresis can disappear almost immediately. The main reason for this is that these foods can produce a metabolic reaction in children, causing the bladder wall to swell and reduce its capacity, and promoting the smooth muscle to become rough and produce spasm. At the same time, this metamorphosis can cause the child to sleep too deeply and cannot wake up when there is urine, resulting in urine loss. 2. Spicy and stimulating food. Children’s nervous system is immature and easily excited, so if they consume such foods, the cerebral cortex can be dysfunctional and urine loss can easily occur. Therefore, spicy and irritating foods should be avoided in the diet. 3. Drink more water after dinner. After 4 p.m., urge children to control the amount of water they drink, avoid using a liquid diet, and drink as little water as possible for dinner, so as not to increase the burden on the kidneys and reduce the amount of urination at night. 4, more salt, sugar and cold food, especially carbonated beverages. More salt and sugar can cause more drinking and urination, cold food can weaken the function of the spleen and stomach, which is not beneficial to the kidneys, so it should be avoided. 5, corn, coix seeds, adzuki beans, carp, watermelon. These foods are sweet and light, diuretic effect is obvious, can aggravate the condition of enuresis, so should be avoided.
