The desire to vomit in early pregnancy is a normal physiological phenomenon. If it does not affect daily life, it usually does not require special treatment, and the symptoms can be improved through dietary modifications and distraction. In early pregnancy, due to the fluctuation of hormone levels in the body, the level of estrogen increases, resulting in slower gastrointestinal peristalsis and prolonged retention of food in the digestive tract, easily triggering nausea and vomiting, which are typical early pregnancy reactions. In addition, the symptoms of nausea and vomiting can be aggravated by the stimulation of odors such as fumes and irritating smells, and accompanied by reactions such as coldness, fatigue and drowsiness, which mostly start in the fourth week of pregnancy and last for about two months, and can disappear on their own as hormone levels return to normal. Pregnant women who want to vomit in early pregnancy can change their diet, adjust the diet structure, choose easily digestible food, eat less and more meals, avoid eating too cold, greasy, spicy and stimulating food, and eat sour food to increase appetite and improve vomiting reaction. If you experience frequent vomiting, increased nausea and vomiting, accompanied by weight loss and decreased urine output, it may be severe pregnancy vomiting, so you should go to the hospital for examination and supplement fluids according to your condition to avoid affecting the health of the fetus.
