The reason for this is not yet fully understood, but it may be due to the increase of HCG, the decrease of stomach acid, and the prolongation of gastric emptying time, and may also be related to mental and psychological factors. Generally, no special treatment is needed, and it can usually be cured by itself, but the specific situation varies from person to person. Cola is a carbonated beverage, which is generally ineffective in relieving pregnancy vomiting because it contains carbonic acid, which may cause flatulence and aggravate the reaction of pregnancy vomiting. To relieve pregnancy sickness, you can eat some easily digestible, sweet and sour food, such as strawberries, lemon, pineapple, or pasta, coarse grains and other foods. Pregnant women with mild morning sickness should try to avoid contact with odors and foods that can easily induce vomiting, and it is recommended that they eat fewer and more frequent meals. Pregnant women with severe vomiting should seek medical attention and be given targeted treatment under the guidance of a doctor.
