Managing high ileostomy output can be a bit of a challenge, but with some helpful tips and a bit of patience, you can find what works best for you. If you're dealing with high output from your ileostomy, here are some suggestions that might help:

1. Consider incorporating thickening foods into your diet. Foods like mashed potatoes, regular potatoes, bananas, bread, bagels, rice, carrots, applesauce, pudding, peanut butter, and oatmeal-raisin cookies can help thicken the output.

2. Try eating small amounts of these stool-thickening foods every 2–3 hours. It's also a good idea to avoid drinking liquids while you're eating and to wait about 20 minutes after meals before having a drink.

3. Some products might help slow down the output. Imodium (loperamide) is one option, but make sure to use it as directed by your healthcare provider. Psyllium husk, found in products like Metamucil gummy bears, has been reported by some to firm up the output and reduce its volume.

4. Make sure to eat substantial meals regularly. If your calorie intake is too low, you might notice that the output becomes very liquid and profuse.

5. Be cautious with foods that might liquefy the output. For some, chocolate can have this effect, but it can vary from person to person.

6. Remember that finding the right balance can take time. Be patient with yourself as you experiment with different approaches, as it might take a while for your body to adjust after surgery.

7. Keep an eye out for any signs of dehydration, such as dizziness or fainting. High output can lead to dehydration and electrolyte loss, so it's important to seek medical attention if you experience these symptoms.
