Morning sickness is a common symptom of pregnant women in the first trimester, but some pregnant women may still have serious morning sickness reaction in the third trimester. Here are some ways to relieve morning sickness:

1. Diet adjustment: avoid eating greasy, spicy and irritating foods, and eat more light and digestible foods, such as rice porridge, noodles and biscuits. At the same time, the intake of protein and vitamins, such as eggs, milk and beans, can be appropriately increased.

2. Eat a small amount of meals: eat 5-6 times a day, don't eat too much each time, so as not to overload the stomach.

3. Avoid fasting: Keeping a certain amount of food in the stomach can reduce the occurrence of nausea and vomiting.

4. Pay attention to drinking water: Drinking plenty of water helps to dilute gastric juice and relieve stomach discomfort. But avoid drinking too much water to avoid edema.

5. Adequate rest: Maintaining good sleep quality and adequate rest time can relieve physical fatigue and stress, and help relieve morning sickness symptoms.

If none of the above methods can relieve the symptoms of morning sickness, it is recommended to consult a doctor or obstetrician in time to get more professional treatment advice.
