The general weight gain range of 23 weeks of pregnancy is 8-12 pounds, the weight change is not obvious in the first 3 months of pregnancy, and the weight increase is about 350g per week on average from 13 weeks onwards, but personal constitution, body absorption, pregnancy reaction and other conditions may affect the pregnancy weight. Some women may have weight gain that does not match the normal range at 23 weeks of pregnancy, at which time the following conditions should be considered: 1. Excessive weight gain: usually caused by excessive diet, if too obese, it is recommended to go to the hospital for regular checkups to see if there is gestational diabetes. Pregnant women should control their diet, avoid overeating, and should exercise properly to prevent the accumulation of fat, resulting in excessive weight gain, which can produce pregnancy-related diseases and affect the physical development of the fetus; 2, too little weight gain: pregnant women may have a heavy pregnancy reaction, which affects the absorption of nutrients, and can choose a lighter diet and eat less and more meals on a daily basis. It is recommended to eat more food rich in protein and high vitamin, eat more eggs, lean meat, fruits and vegetables, drink some pure milk, soy milk, big bone soup, etc. Go to the hospital regularly for ultrasound examination to see how the fetus is developing.
