Women should avoid eating crab for a short period of time after miscarriage.1. In terms of food properties, crab is very cold in nature. After a miscarriage, a woman’s uterus is weak and highly sensitive to various harmful stimuli. If you eat too much cold food, it will easily lead to the symptoms of uterine cold, so that the blood in the uterine cavity can not be discharged in time, and may even lead to dysmenorrhea. 2. After a miscarriage, the immune function of the body will change to varying degrees, and the sensitivity to various allergens may increase, making it easy for food allergies to occur. The crab is a seafood food, which has a high chance of causing food allergic reactions and should be avoided as much as possible after miscarriage. 3, crab also has a certain blood-breaking effect, so if you eat crab too early after miscarriage, it may lead to excessive postpartum bleeding.
