The symptoms of nausea and hiccups are common in early pregnancy and some pregnant mothers even experience vomiting, bloating and loss of appetite, which are mainly related to hormonal changes in the body. Most mild nausea, acid reflux, belching and other symptoms can be relieved by themselves, so pregnant mothers do not need to be nervous. If the early pregnancy reaction is obvious, you can regulate it through diet, such as a light diet, and try to eat less and more meals. In addition, relaxation and rest can improve the symptoms of early pregnancy. In case of serious upper gastrointestinal discomfort, you can go to the hospital if necessary and cooperate with the doctor to give medication. For the sake of safety, it is better for pregnant mothers not to use medication throughout pregnancy to avoid affecting the fetus.
