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

Now you have all the details about ‘what are foamies.’ However, vomiting white foam can also occur in people without a geriatric cause. Some of the other reason for having a foamy vomit is given as follows:

Vomiting on An Empty Stomach

If you are continuously vomiting, you’ll soon be out of food content. If you continue to vomit, your vomit would contain mucus, stomach acid, and swallowed saliva. This makes it appear white and foamy.

Certain Foods

Consumption of ice cream and carbonated drinks, spicy and acidic foods make vomit appear foamy and frothy, so if you want to avoid a foamy mouth after gastric sleeve, cut down the consumption of those foods.

A balanced diet will help you to stop thinking about ‘what are foamies’ for good.

Excessive Alcohol Consumption

Too much consumption of alcohol irritates the stomach lining. This can lead to indigestion, diarrhea, and vomiting. The morning after, you can have a bad hangover with a headache, nausea, and vomiting. The vomit might appear frothy with a tinge of yellow.

If you ask my honest recommendation on how to get food unstuck after gastric bypass, I would say you cut your alcohol during the Friday nights to enjoy the Saturday mornings.

The stomach contains millions of flora and bacteria, which are suitable for digestion. However, yeast infections can always cause diarrhea and vomiting. Vomit might appear white and foamy.

Drugs like ibuprofen, morphine, aspirin, antibiotics, etc., can induce vomiting as a side effect. Consult your doctor before taking any of these medications if you have a history of frothing after gastric sleeve.

  • 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.
