It is never a good solution to skip meals, especially during pregnancy. Not eating enough means depriving your body of all the nutrition and energy-inducing foods that are important for your fetal health.
If you are someone who experiences nausea and vomiting during pregnancy, you can choose to eat in small quantities rather than skipping your meals. Whatever amount of food you eat, include all the nutrients and bulk up on your fibre-intake.
Drink a lot of water, so you stay hydrated. Add some lemon to it, to get rid of the nausea and feeling of vomit.
Additionally, you can always seek medical help. Consult your doctor and ask them to advise you on the same.
