In the early stages of pregnancy, if there is constant spitting up, it is mainly due to the increase of estrogen in the body after pregnancy, which will lead to water and sodium retention in the body, causing a mild edema in the oral mucosa, so the symptoms of constant spitting up will occur. In this case, you can contain some plums to avoid this old spitting up. It is also recommended to have more snacks and eat snacks often to avoid this situation. After pregnancy, it is also recommended to eat foods that are easy to digest to avoid increasing the burden on the gastrointestinal tract. When you are about 45 days pregnant, due to the increase of hormone levels in your body, you often also experience nausea, vomiting and other gastrointestinal symptoms. It is recommended to eat as much as possible when you can, so as to avoid aggravating nausea and vomiting by rubbing the gastric mucosa in an empty stomach. If the nausea and vomiting are particularly severe and you cannot eat, go to the hospital as soon as possible for the appropriate examination and give timely treatment.
