What precautions should I take before traveling to protect my rather fragile stomach and intestines? Is taking a probiotic a good solution?

Before traveling, it is important to take precautions to protect your stomach and intestines, especially if they are sensitive. Taking a probiotic can be a good way to help maintain healthy gut flora, but it may not be enough to protect against certain harmful bacteria. It is advisable to consult with a pharmacist or doctor to determine if you need any vaccines or antibiotics before your trip.
