(HealthDay News) -- During the first trimester of pregnancy in particular, hormonal changes are responsible for nausea and vomiting that's often labeled "morning sickness."

The womenshealth.gov website suggests how to minimize symptoms of morning sickness:

• Eat slowly, and consume a number of small meals throughout the day instead of three large ones.
• Don't eat foods that are fried, spicy or greasy. Cereal, rice or bananas are good choices.
• Eat your meals well before lying down.
• Eat dry foods, such as toast or crackers, after waking in the morning.
• Avoid smells that can trigger nausea.
