Yes, if you are pregnant and have gastroenteritis, there are some things you can do to help alleviate your symptoms. It is important to stay hydrated by taking small sips of fluids frequently. You can also try eating light foods like soups, broths, toast, eggs, and brown rice while avoiding very fatty or sugary foods. If over-the-counter medications for nausea are not enough, it's recommended to consult with a pharmacist for other options. It's important to rest and listen to your body during this time.
