If you are experiencing a runny tummy during your 37th week of pregnancy, it is important to take steps to manage this discomfort. Firstly, ensure you stay hydrated by drinking plenty of fluids like water and electrolyte-rich beverages. Avoid foods that may exacerbate diarrhea such as spicy or greasy foods, caffeine, and dairy products. Instead, opt for bland and easily digestible foods like bananas, rice, toast, and applesauce. It's also crucial to maintain good hygiene practices and wash your hands thoroughly before handling food or eating. If symptoms persist or worsen, consult your healthcare provider for further guidance and potential treatment options.
