I received a telephone call from my sister who lives in the United States. She is experiencing moderate symptoms of morning sickness, but she tells me that she was advised to treat her symptoms only pro re nata- meaning, when symptoms re-emerge. Does this make sense?
No, it does not. Typically, nausea and vomiting of pregnancy continue for weeks and months, and in some cases until labour. It is critical to treat symptoms consistently so the woman can maintain adequate fluid and calorie intake. When symptoms improve, the dose of antiemetic medication should be decreased gradually.
我接到了住在美国的姐姐打来的电话。她有中度晨吐症状，但她告诉我，医生建议她只按需治疗——也就是说，当症状再次出现时。这有道理吗？
没有道理。通常情况下，怀孕引起的恶心和呕吐会持续数周和数月，在某些情况下，甚至会持续到分娩。持续治疗症状非常重要，这样孕妇才能保持充足的液体和热量摄入。当症状改善时，应逐渐减少止吐药物的剂量。
