Nausea in pregnancy
Diet
Mixing solids and liquids can increase nausea and vomiting because it can make the stomach feel fuller and, in some women, can cause gas, bloating, and acid reflux. Eating small portions every 1 to 2 hours and eating and drinking separately can be helpful. For example, eat a small portion of food, wait 20 to 30 minutes, then take some liquid.
Eat whatever you can tolerate. Other than in the case of severe malnutrition, fetuses generally receive the nutrition they require—sometimes to the detriment of the mother. For example, the calcium depletion from the fetus can cause a mother’s teeth to decay.
There are supplements on the market that the mother can consume if she is unable to digest a full meal, such as liquid supplements, puddings, and protein bars to replace the lack of essential maternal nutrients.
Fluids
A pregnant woman should try to consume at least 2 litres of fluids daily in small amounts taken frequently. Colder fluids, including ice chips and Popsicles, appear to be easier to tolerate and can decrease the metallic taste in the mouth. There are also commercial products available that maintain the electrolyte balance (sports drinks, etc).
