Eating and drinking while wearing an ileostomy or colostomy bag A porridge-like consistency is preferable since it is easier to manage. Some foods can create stoma obstructions and should thus be avoided or consumed with caution. Examples include fiber-rich foods like bread, potatoes, and vegetables. Fiber can block your stoma opening, causing you to experience pain or nausea. As long as you are eating a healthy diet that includes plenty of fruits and vegetables, then there is no reason why you could not eat porridge daily. The key is finding a recipe that you enjoy that also fits with how you feel after surgery. For example, if you feel nauseated when you eat meat, then a porridge recipe would not be a good choice for you. Many people ask whether they can eat porridge after their operation. The answer is yes, you can eat porridge after surgery as long as you follow the instructions of your doctor. You should only eat things that are easy for you to digest after your surgery. If you have an ileostomy, then proteins and fibers will not go down easily. So, for the first few weeks after your surgery, you should only eat foods that are high in liquid content like soups, porridges, and juices. As you get used to your new lifestyle, you can add some soft foods like mashed potatoes or pasta to your diet.
