Nausea during pregnancy, commonly called “morning sickness”, is experienced by about four out of five women. Although called morning sickness, it may occur at any time during the day or night. The causes of morning sickness are not fully understood. This nausea and sometimes vomiting is believed to be related increased levels of a hormone produced by the placenta called human chorionic gonodatropin (HCG).

ADVICE ABOUT DIET:
Eat small amounts every 2-3 hours.
EAT easily digested carbohydrates (fruits, fruit juices, breads, cereals, rice, pasta, potatoes).
Eat low-fat, high protein foods (lean meat, broiled or canned fish, poultry without skin, eggs, boiled beans)
FLUIDS:  Are better tolerated cold, clear, carbonated or sour (ginger-ale, lemonade, popsicles). Electrolyte replacement drinks (GatorAid) consume 30 minutes before or after food to minimize effect of full stomach.
Drink soups and other liquids between meals, rather than with meals, so as to not overly distend the stomach and trigger vomiting.
Avoid greasy, fried foods hard to digest and offending aroma.
Lightly season food, but salt to taste.
Snack (yogurt, milk, juice, bread, or sandwich) prior to bed or during the night.
Eat a piece of bread or crackers before getting out of bed in the morning.
Avoid brushing teeth immediately after eating.
Sit upright after meals to reduce gastric reflux (heartburn).
Try whatever appeals to you in an aroma free quiet environment including atypical food/beverages such as potato chips, lemonade, lemons (to smell) and Granny Smith apples.
AFTER RECOVERY (from SEVERE vomiting) as you restart oral feeding consider the BRAT diet consisting of bananas, rice, applesauce, and toast then advance diet as tolerated.  Getting protein intake is also key in helping reduce nausea.
Craved food should be eaten immediately or the window of opportunity may be lost.
