What are Foamies?
The Foamies are a blend of mucus and broken-down foods which come up instead of vomit. Gastric bypass patients are usually fitted with a sleeve or pouch. Its primary purpose is to limit the amount of food you eat. It also has a small structure which slows down the food intake.
Now, when bariatric surgery patients eat too fast or don’t chew their food well, there might be problems with the pouch. They might eat something that is not compatible with the pouch or overeat the same thing. All of this might lead to them regurgitating the food in the form of foams.
When you eat too fast or too much, the food tends to block the stoma. As a reaction, the body produces a whole lot of mucus to help pass the food. But instead of being of any help, it produces this slimy foamy concoction that comes up like vomit.
What is foamies or what causes foamies after gastric bypass will be the main focus of this article. So, stay put.
Foamies vs Vomit
Vomiting on its own doesn’t feel good. But, if you get the Foamies, then it’s worse. However, it’s nothing to be scared of. It’s just a very annoying situation. Foamies are quite different from vomiting.
While you vomit, you usually regurgitate the food content along with bile and stomach acid, which might lead to a burning sensation in the mouth and throat. But after gastric bypass surgery, your stomach is no longer connected to your alimentary canal.
Thus the bile and stomach acid don’t come up. If you are regurgitating acid or bile along with Foamies, it might be a dangerous sign. You must immediately call your doctor if you notice something like this.
Bariatric surgery patients can typically have Foamies as they get used to the new food habit. It is usual for them to regurgitate the excess amount of food taken. So, there is nothing to be worried about. However, you should be aware of avoiding such annoying conditions. Let’s get to know how to get rid of the foamies.

What to Do When You Get the Foamies?
Foamies don’t go away as quickly as vomit. If you ask me ‘how long do foamies last,’ let me tell you that it can persist for hours. Thus, something needs to be done about it. One of the easiest ways to get rid of Foamies is to expel everything in your sleeve or pouch.
It’s not so easy in the beginning and might take some practice. But if you can vomit out or expel the irritating food material from your pouch, then it might provide some relief. You might have trouble vomiting out the food content in your pouch.
In this case, you can try taking something that breaks down protein. You can try eating papaya enzymes which contain papain. This helps break down protein faster. Some home remedies include taking pineapple juice before meals will provide some extent of relief.
If your Foaming tendencies persist longer than normal, then it is best to consult your doctor. They would look into the situation for underlying conditions. They might suggest you medication for a few weeks to resolve your sliming gastric bypass issue.
Other Causes of Foamies

Avoiding Foamies
Foamies can get very annoying. However, it’s not that hard to avoid this annoying condition. You just need a little bit of practice. Here is what you should do:
- It is suggested that taking smaller bites and eating in smaller portions helps avoid the Foamies. Try eating on a smaller plate with small bites. This might take you longer to finish your food. But you should always be mindful of your condition.
- You should chew your food well. Chew your food until it resembles a mushy consistency. If you swallow poorly chewed food, it might block your stoma.
- Avoid dry foods. Dry fish, chicken, or crackers might be hard to digest. You should rather opt for lightly spiced curries or gravies. Food with a soupy consistency will go a long way.
Prevent Gas Build Up After The Foamies
If you do not flush out your pouch correctly after getting the Foamies, there might be some gas build-up. The remnant food at the bottom of your pouch will ferment. This would produce gases. This would fill up your pouch and create pressure or pain.
The pain might get severe depending on the amount of gas production. To avoid this, you must drink as much water as you can. It would help flush out the remnant food particles in your pouch.
