Pregnant women can drink rehydration salts, but they need to take them under the guidance of a doctor. During pregnancy, changes in hormone levels in the body can lead to gastrointestinal tract dysfunction, which can easily lead to diarrhea symptoms due to improper diet, or infectious factors. Prolonged diarrhea can easily lead to dehydration in pregnant women and affect the growth and development of the fetus. Therefore, in the case of severe diarrhea, pregnant women can follow the doctor’s instructions to replenish fluids, such as oral rehydration salts or intravenous electrolyte infusion. For example, low potassium may induce cardiac arrhythmia, which may lead to death in serious cases, while rehydration salt, because of its balanced ions, can not only replenish water, but also replenish sodium, potassium, calcium and magnesium plasma, which is very important for the stability of the human body environment. . In addition, while taking medication, pregnant women also need to pay attention to dietary hygiene and drink warm boiled water in moderation. In our daily life, we should eat low-salt, low-fat and coarse-fiber food, avoid too cold, spicy, stimulating and greasy food, and eat more fresh fruits, vegetables, milk, eggs, lean meat, etc.
