It is common for pregnant women to be more sleepy in early pregnancy because in early pregnancy, hormone levels change significantly, mainly the level of chorionic gonadotropin will be high, and the change in hormone levels will lead to nausea, vomiting, weakness and drowsiness. Since these symptoms can cause discomfort, many pregnant women are more likely to want to sleep and strain during early pregnancy. For this situation, no special treatment is needed. Proper rest helps to relieve the early pregnancy reaction, and it is also recommended to have a lighter diet, and for more serious pregnancy vomiting, thyroid function should be checked to exclude thyroid-related diseases.
