Termination of pregnancy before the 28th week of pregnancy is called miscarriage, and weight loss should not be carried out during the month after miscarriage. This is because a woman’s body is weak after a miscarriage, and there is still obvious discharge of malignant fluid, her immune system is particularly low and she needs to increase nutrition to replenish her body’s needs, and the pelvic floor muscles need time to repair. If weight loss is carried out at this time to reduce the diet and affect the nutritional intake, unsuitable exercise will lead to increased vaginal bleeding and affect the recovery of the uterus, which will also affect the repair of the pelvic floor muscle and even lead to uterine prolapse and affect the future life and work. After miscarriage, the body resistance is low because of dieting and reduced nutritional intake, which makes the body weaker and more susceptible to bacterial or viral infections and diseases. After a miscarriage, women should rest for half a month, eat a light and nutritious diet, eat more high-protein foods to replenish the body’s nutritional needs, such as eating fish, shrimp, ribs, etc., and moderate activities such as slow walking to restore the body to normal faster.
