It is generally safe to consume glucose during pregnancy, even if you are experiencing vomiting and diarrhea. Glucose can provide quick energy and help prevent dehydration. However, it is important to consult with your healthcare provider before making any dietary changes or taking any supplements. They will be able to assess your specific situation and provide personalized advice. Additionally, they may recommend alternative sources of hydration and nutrition that are better suited for your condition. Remember to stay well-hydrated by drinking plenty of fluids, such as water or electrolyte solutions recommended by your doctor.
