Morning sickness and nausea are common in pregnant women. Most nausea occurs during the early part of pregnancy. In most cases this discomfort improves when you enter the second trimester. For some women, morning sickness and nausea might last longer, even for the entire nine months.

The changes in your body can cause nausea and vomiting when:

• you smell certain things,
• you eat some foods,
• you are tired,
• you are stressed,
• or for no apparent reason

You may be able to reduce nausea by changing when and what you eat. Try these tips:

• Eat smaller meals, such as six to eight small meals instead of three larger ones each day.
• Don’t go for long periods of time without eating.
• Drink fluids between, but not with, meals.
• Avoid foods that are greasy, fried, or highly spiced.
• Avoid strong, foul and unpleasant odors.
• Rest when you are tired.

Severe nausea and vomiting in pregnancy is rare. But constant vomiting can cause you to lose needed water and become dehydrated. If you feel that your nausea or vomiting is keeping you from eating right or gaining enough weight, talk with your doctor
