Some pregnant women may have nausea, vomiting, dizziness, drowsiness and fatigue, but some may simply feel nausea without vomiting, and a few may not feel anything throughout early pregnancy, without any symptoms, and only discover early pregnancy when they go to the hospital for examination. Pregnant women who only have nausea and no vomiting have a mild degree of early pregnancy reaction. This phenomenon occurs because the secretion of estrogen and progesterone in large quantities changes the secretion of certain glands and weakens the function of the digestive system, including the stomach, intestines and gallbladder, resulting in delayed digestion and prolonged retention of food in the stomach, which often makes the stomach feel bloated after meals, and the stomach feel regurgitated when the stomach acid increases. At present, there is no effective way to eliminate this reaction, but the following methods can be weakened or temporarily alleviated: 1, slow down the speed of eating, eat less and more meals: the reason for regurgitation is due to the reduced digestive function of pregnant women, at this time to chew slowly when eating, in order to facilitate food digestion. At the same time, we should eat less and more meals to reduce the burden on the stomach and not to make a large amount of food accumulate in the stomach to reduce the symptoms of regurgitation; 2, eat less acidic food: If you eat acidic food again when you have regurgitation, the reaction will be stronger and even cause vomiting. If vomiting often, it will also lead to malnutrition. If pregnant women feel regurgitated, they can eat appropriate alkaline food, such as baking soda cookies, etc.; 3, appropriate exercise after meals: it helps to promote gastrointestinal peristalsis, so that food is quickly digested and absorbed, which can relieve the symptoms of regurgitation.
