Your body does not accept any foreign or harmful substance you might have indigested. Vomiting occurs when your body tries to get rid of said substances. But these are not the sole reasons you might puke, as stomach bugs or other factors can cause this. But what if you’re throwing up foam? We’ll list some culprits behind foamy vomit.

Why Am I Throwing Up Foam?

Vomiting means throwing up your stomach contents through your mouth. So it can be worrisome when you notice that it looks like foam. If headaches, abdominal pain, and other symptoms also appear, it could indicate an underlying gastrointestinal condition. Usually, throwing up foam is due to these reasons:

Consuming Certain Foods or Drinks

Some foods might taste delicious, but they aren’t exactly friendly for your insides, especially if you eat them on an empty stomach. Lovers of acidic carbonated drinks might find themselves in this situation. In addition, eating spicy, fatty, and acidic junk foods can also be the culprit behind foamy vomits.

Acid Reflux or GERD

You might be throwing up foam due to acid reflux, which occurs when the corrosive stomach acids back into the esophagus. Frequent episodes of acid reflux might be a symptom of a more severe condition, gastroesophageal reflux disease (GERD).

Drinking Too Much Alcohol

Nausea, indigestion, stomachache, and irritated stomach lining can occur if you drink excessively. The hangover that follows after drinking too much alcohol can come with a headache, dehydration, and the urge to vomit. Many people will notice that the vomit is foamy, with a hint of yellow.


Your esophagus is susceptible to getting infected by the Candida fungus. The mixture of yeast cells, mucus, and stomach acid can make your puke look yellow or white. You’ll also experience difficulty swallowing, bloating and flatulence, bad breath, and more. The following increases your chances of candidiasis or yeast infection:

  • Weak immune system
  • Uncontrolled diabetes
  • Eating a lot of sugar
  • Taking antibiotics


Pregnant women experience morning sickness and acid reflux due to the changes in their hormone levels. Also, the physical aspect of the body changes, and the baby’s growth can lead to this condition too. With the baby pressing against the stomach, an expecting mother might feel the need to vomit. Since the stomach empties during the night, it can cause the vomit to appear foamy.

Stomach Infection

Vomiting can be a result of stomach infections. You’ll also experience abdominal pain, diarrhea, and constipation due to bacterial or viral gut infection.

Hiatal Hernia

Throwing up foam is also an indication of a hiatal hernia.

Our diaphragm keeps the stomach acid from backing into the esophagus. However, GERD or acid reflux can occur when an opening in the diaphragm allows the top part of your stomach to push upwards into your chest. Consequently, symptoms like heartburn, chest burning, burping frequently, and a foul taste in the mouth appear. Minor hiatal hernia usually goes unnoticed. A doctor’s diagnosis is how many people get to know they even have this condition. Still, a large hernia can cause damage and inflammation.

What to do?

Throwing up foam has many causes, including medical conditions like hiatal hernia, candidiasis, and acid reflux/GERD. Visiting a doctor to know the problem source is recommended instead of self-diagnosing.
