After pregnancy, the swollen uterus will put some pressure on the expectant mother\’s bladder. In order to relieve the symptoms of compression, expectant mothers should not drink too much water each time. They only need to maintain a daily drinking volume of 1000ml to 1500ml. Case Review According to the \”Daily Mail\” report, Sarah Smith, a British female reporter, drank 2,000 ml of water from 8 a.m. to 10 a.m. every day for a month. Comparing the before and after photos, he looks 10 years younger. After seeing this report, Ms. Huang, who was already 8 months pregnant, found out that her prenatal B-ultrasound showed oligohydramnios. As the saying goes, you get what you eat to make up for it. Ms. Huang also learned from Sarah Smith and drank 3,000 ml of water every day. But things went counterproductive. Half a month later, Ms. Huang underwent another B-ultrasound test, and the result was that the amniotic fluid was even less. Two days later, Ms. Huang was rushed to the hospital because she suddenly urinated blood. After rescue, Ms. Huang and her child were out of danger. According to the attending doctor, Ms. Huang had suffered from acute nephritis before. The doctor said that drinking so much water put a huge burden on the kidneys, which is why she developed symptoms of hematuria. Fortunately, she was sent to the hospital in time and was not life-threatening. How much water is appropriate for expectant mothers to drink? In addition to the water they get from daily food, expectant mothers only need to maintain 1000ml to 1500ml to meet the needs of the body. In the third trimester, it is best to control it within 1000ml. In addition, expectant mothers should control the time of drinking water. Drinking a glass of water before breakfast can not only replenish the water lost during sleep, but also diuretic and laxative. In daily life and work, drink water every 1 to 2 hours, and stop drinking water 2 hours before going to bed to avoid affecting the sleep quality of expectant mothers. Several misunderstandings about drinking water among expectant mothers: 1. Drink only when you are thirsty. If an expectant mother is already thirsty, it means that the body is dehydrated to a certain extent. Therefore, it is recommended that expectant mothers drink water every 2-3 hours and do not wait until they are thirsty. 2. Drink water that has been boiled repeatedly. Mothers who drink boiled water that has been boiled for a long time or that has been boiled repeatedly can easily cause blood poisoning. Because after repeated boiling of water, the concentration of harmful substances such as silver nitrite, nitrite ions and arsenic in the water increases relatively. Drinking boiling water that has been boiling for a long time will cause the low iron hemoglobin in the blood to combine into methemoglobin that cannot carry oxygen, causing blood poisoning. 3. Drink unboiled water. The chlorine in tap water interacts with the organic matter remaining in the water to produce a carcinogen called \”trihydroxy\”. Pregnant women should also not drink boiled water stored in a thermos bottle for more than 24 hours, because as the water temperature in the bottle gradually drops, the organic matter containing chlorine in the water will continue to be decomposed into harmful nitrites, which is extremely detrimental to the internal environment of the pregnant woman\’s body. 4. Drink tea that has been brewed for a long time. Tea contains a lot of tannic acid, theophylline, aromatic oils and multivitamins. If the tea is soaked in the water of a thermos cup, the multivitamins will be destroyed and the nutrition will be reduced, making the tea bitter. , the increase in harmful substances will cause digestive and nervous system disorders after drinking. 5. Drink only purified water. Purified water is obtained by filtering tap water. Although it filters out many impurities, it also filters out minerals that are beneficial to the body. When pregnant women drink pure water,It will take away useful trace elements from the human body, reduce the body\’s immunity, and be detrimental to the fetus. Water is a daily necessity for the human body. Safety issues cannot be underestimated. Pregnant women need to pay more attention to ensure the health of mother and baby.
