I had previously written about dealing with thick ostomy output, but many ileostomates have the opposite problem: liquid output. In this post, I’d like to go over a few tips that you can use to thicken up your output. These tips apply to colostomates who have loose stools but are directed more towards ileostomates.

Why Worry About Liquid Or Loose Output?
For the most part, there’s nothing really wrong with having liquid or loose output, but it does come with a few challenges:
- liquid output is more likely to cause leaks.
- liquid output can shorten the life of your wafer by speeding up erosion.
- liquid output can clog pouch filters and/or leak through them.
- emptying a pouch full of liquid can be messy (especially if you have mobility issues).
- liquid output could lead to dehydration more easily.
- a high-output stoma could mean that nutrients don’t have time to be properly absorbed.
- you may need to empty your pouch more often than you’d like.
Causes of Liquid Ostomy Output
Ostomates with Short Bowel Syndrome are more prone to having liquid output with fast transit of their food through their small intestine, but there are other reasons which can cause it too.
Here are a few of the more common causes:
Dietary
The following foods and beverages can cause a dramatic change in your output’s consistency. You’ll likely be able to identify the culprit within hours of consuming them:
- Coffee or tea
- Sport drinks
- Soda/Pop/Soft drinks (both diet and regular )
- Fruit juices
- Chocolate
- Certain fruits (for me, it’s cherries)
- Artificial sweeteners
- Alcoholic beverages (especially wine)
- Fried foods
- Hot/spicy foods
- Non-vegan foods like dairy (or other lactose-containing food, if lactose intolerant)
For the most part, very few of the items listed are needed (or desired) in a healthy diet, so if you can cut them out, you’ll find benefits in more than one way.
Drinking with meals or drinking too much at one time can loosen your output too.
Laxatives, Medication & Supplements
Some medication or supplements can cause our output to become loose. If you are taking a laxative, it may also cause loose stools.
Antibiotics can cause liquid output (diarrhea) that tends to pass within a few days. You may be asked to take a probiotic while you are on antibiotics to help balance out your gut flora. Keep in mind that you should never stop taking antibiotics until you’ve completed the full course.
Viral or Bacterial
There are many types of bacteria and viruses that can cause diarrhea or liquid output. If you’ve experienced an unusual change in your output, you may fall into this category.
Blockage
When you experience a blockage, your body will try to flush out the blockage, which can result in liquid output.
I didn’t have this at all for my last blockage, but many ostomates report having liquid output while they were obstructed.
This will usually be accompanied by other symptoms that are typical for a blockage like abdominal pain, pain with peristalsis (this comes in waves as your gut tries to move things along), nausea and possibly vomiting.
If you suspect a blockage, you’ll want to contact your GI or head to your local ER.
For tips on preventing and dealing with blockages, see THIS article.
Tips for Dealing With Liquid Output
Talk to your doctor if you suspect food poisoning or another bacterial/viral cause of your liquid output. As suggested above, if you suspect a blockage, you’ll want to contact a medical professional.
For “normal” causes, you might want to try the following tips:
Dietary
One of the most effective ways to deal with liquid output is to make a few dietary changes or modify the way you eat.
Keeping your meals and beverages separate, or drinking throughout the day (rather than in one sitting) can help.
The following foods are also known to thicken ostomy output:
- Starchy foods like pasta, potatoes, rice, white bread
- Crackers
- Potato chips
- Applesauce
- Bananas (especially when under ripe and without spots)
- Nut butters (peanut, almond, sunflower seed, etc)
- Oatmeal
Most of these foods can be considered healthy, although, don’t depend too much on the white bread, white pasta or chips if you don’t need to.
I remember one fellow I spent a hospital room with had to consume several bags of potato chips plus Imodium to slow his output down because of his short bowel.
Gelling agents
A popular choice among ostomates is to use gelling agents in their pouch.
These can come in tablets, powder, capsules (usually made with animal ingredients) or sachets, but they all work in a very similar fashion: Add the gelling product to your pouch as directed and it will thicken up when it comes in contact with your output.
Here’s a demo of how gelling products work:

I’ve reviewed the ConvaTec Diamonds sachets, but I’ve also tried other products and they generally work well. You should be able to get samples to try.
Anti-Diarrheal Medication
Many ostomates will be told by their doctor or stoma nurse to take a product like Imodium to slow down their output. I would personally try this last if all other options failed, however, if you have a very high-output stoma which is causing ongoing nutritional problems or dehydration, this might be an option you’ll want to try until things get stabilized.
Fibre Supplements
This is not an option I’d recommend, nor is it something that your doctor is likely to recommend either. There are fibre supplements which can bulk up stool but they carry a risk of causing a bowel obstruction too. Do not try this unless explicitly told by your doctor.
Guar Gum
Guar gum is made from guar beans, but it’s been used as a thickening agent in various products for quite some time. There are claims that it has eight times the water-thickening effect compared to cornstarch, which is pretty impressive!
As a supplement, this often comes in tablets, but you should consult with your doctor to see if it’s a good option for you. Like fibre supplements, there’s a risk of slowing things down too much.
Consider Using a High-Output Appliance
If you find that your liquid output is difficult to manage when you’re wearing a traditional ostomy pouch, consider a high-output appliance.
These styles of pouches have larger capacities and are designed to better manage liquid output.
The product in the photo above is one of Coloplast’s high-output appliances. I did an overview of them HERE, and it may be an option worth considering.
Closing Thoughts
Some ostomates don’t mind liquid or loose output.
But if you’re one of the people who find liquid output to be problematic, then I hope the suggestions listed will come in handy.
In addition to the tips included above, you may also want to try using barrier rings or moldable wafers to help prevent liquid output from leaking under your appliance.
QUESTION: What do you do to thicken your output?





My stoma is producing water.. It is very watery and i cannot sleep at night because it leaks
@KathreneLozari
Hi Kathrene,
Have you considered using a gelling product to thicken up your output? I find that they can help quite a bit in preventing leaks: https://www.veganostomy.ca/guide-to-ostomy-gelling-products/
I wonder if i could put psyllium powder in my pouch to thicken this watery output. I have a lot of capsules of it that my SIL left here after visiting. Maybe i could try emptying one capsule and see what happens.
Try it in water first (to see how much it absorbs) . A single sachet used for ostomy bags can typically soak up 1/2 – 1 cup of fluids without trouble. If the powdered psyllium works, I see no harm in using it :)
I have an active stoma and mostly liquidy output. I change my appliance when I get a chance so no way I can plan when my stoma isn’t active. I would get so irritated when I would finish cleaning my abdomen and my stoma would push out liquid, even with a tissue wrapped around it so I improvised. I use a small condiment container like you get soy sauce or catsup in at a restaurant (I actually have the nurses when I’m in the hospital get me a stack) and cut the bottom out to the size of my stoma. I wrap waterproof tape around the bottom so I won’t hurt my delicate stoma and place it over my stoma. I push a small amount of kleenex or gauze down in over the opening of my stoma which absorbs any output. I don’t stand but lay back on my bed while I change my appliance so the container stays put. The skin protector spray is sticky and that helps keep it in place too. I can clean well, let things dry and prepare my appliance with the container in place. Then I lift it off and position my appliance over my stoma. Works well for me.
Windemere, welcome to the forums! That’s a brilliant way to improvise!
Your technique reminds me of this stoma cup product: https://amzn.to/2UJotKo (Unfortunately, it’s not currently available on Amazon, but you can likely find it elsewhere).
That product has tabs on the side, which allows you to use a support belt to hold the cup in place. You may be able to modify the container you currently use to work with stoma belts too :)
Actually, since I use it so I have access to my complete abdomen for cleaning, the belt is too wide but it gives me an idea to make a ‘belt’ out of a ribbon or narrow elastic to really hold the cup against my stomach. I’m going to try a bit of the adhesive goop to see if that holds it more firmly. Thanks for getting back to me.
Similarly but maybe a little easier I used scissors to cut out the circular hole in an old bag I also cut a piece of cellophane wrap slightly larger than the appliance hole I just cut .When changing/emptying my bag, I place the cellophane over the circular whole previously cut and snap it on my wafer This gives a tight temporary seal allowing for a cleaner change as well as a quick shower Just a thought Ps. I have been using the flushable bags for sometime and enjoy them very much
Hello Pam and welcome.I am very sorry to hear of you and your sister’s struggles. This is a real and ongoing challenge.I am not a health care professional.. so take what follows in that light. Always seek more advise from medical people. BUT…I think you need to break this down into two parts. One part of your problem is keeping your sister clean. Is she physically able to stand in a shower? ( none of us soak anymore).If so, then the problem is keeping the pic line and the ostomy bag dry during a shower.I have had great success with Glad Press and Seal: https://www.amazon.com/Glad-Pressn-Seal-Plastic-Food/dp/B0014D5NVS/ref=sr_1_1_sspa?ie=UTF8&qid=1532798267&sr=8-1-spons&keywords=glad+press+and+seal+food+wrap&psc=1I had a recent foot injury with lots of stitches that had to stay dry. And I have an ileostomy.I was able to wrap both my foot and my bag area ( with the bag attached) in press and seal and shower. Just empty the bag, and while lying down pull out a big enough piece of the plastic to cover that area ( like 10 inches or so). and PRESS it down over everything. It releases really well after.For the pic line ( which I have never had ..so bear that in mind) I think you could cover it in a couple of layers of the plastic sheet..first a smaller one, followed by a larger one. Press it down well over the whole thing and all the skin. This stuff does not stick to my ostomy appliance nor the pretty large scab on my foot.Try it on yourself first. Just stick it over a piece of gauze or something then shower.Maybe just getting clean would be a good first step in your sister’s ongoing care.Good luck. Let us know. Press and seal is available in any grocery store… I included the Amazon link so you could just see the package.( this should eventually be on another thread since its pretty off topic for the name of this thread).
couple of garbage did the trick for me when my foot was injured. simple…. no fuss n muss. :-)I know lets out this on a different thread!!!
Hi Dawn, you have adopted a great approach to help yer Mom and others as well. I wish you all the best
