Pregnancy vomiting, hiccups and dry heaves can be relieved by eating less and more meals, healthy diet and proper exercise. 1. Eat less, eat more: Usually after pregnancy, patients can change the habit of eating three meals a day to eat less, eat more, and ensure sufficient nutritional intake. 2. Healthy diet: During pregnancy, patients should try to avoid eating foods that are heavy in flavor and fried, as these foods will stimulate the stomach and produce dry heaving. Pregnancy vomiting, hiccups and dry heaves suggest eating more fresh fruits and vegetables. 3. Appropriate exercise: patients can take a walk outdoors in the morning after getting up to breathe fresh air, which can maintain a relaxed state of mind. When the patient’s mental state is good, the food is easy to be digested, and the symptoms of dry heaving may be relieved. If the patient’s pregnancy vomiting hiccups and dry heaving is serious, he should consult a doctor in time and under the guidance of the doctor for formal treatment.
