The lack of appetite in the early stage of pregnancy is a normal early pregnancy reaction. Pregnant women are advised to ensure sufficient sleep, avoid staying up late, and can increase the number of naps; try to eat dry food and reduce the intake of soup; eat less and more meals and avoid too spicy and stimulating food; try more starchy food, such as cookies and steamed buns; eat the food you like, but do not be partial and have balanced nutrition. The increase of energy required by pregnant women in early pregnancy is not a lot, as long as there is no starvation ketone body in pregnant women’s urine and the energy is sufficient. Relax your emotions and avoid tension. Early pregnancy reaction usually relieves itself after 12 weeks of pregnancy.
