Causes of Bloating and Gas from Pizza

There are several things that could be making you gassy and bloated when you eat pizza.

Lactose Intolerance

Lactose intolerance is a common cause of bloating and gas after eating pizza, as it contains cheese, which is a dairy product.

People with lactose intolerance can’t properly digest lactose, a sugar found in milk and dairy products.

This leads to gas, bloating, and stomach pain after eating pizza.

One can opt for lactose-free or non-dairy alternatives, or use lactase tablets like Lactaid to help digest lactose.

Celiac Disease and Gluten Sensitivity

Celiac disease and gluten sensitivity can also lead to bloating and gas after eating pizza.

Gluten is a protein found in wheat, barley, and rye, which are common ingredients in pizza dough.

People with celiac disease or gluten sensitivity have an immune reaction to gluten, damaging their small intestine lining and causing gas, bloating, and other digestive issues.

Avoiding gluten by choosing gluten-free pizza options can help alleviate these symptoms.


FODMAPs (Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols) are short-chain carbohydrates that can cause gas and bloating in some people, particularly those with irritable bowel syndrome (IBS).

Pizza toppings like onions, garlic, and certain vegetables can be high in FODMAPs, leading to bloating and gas.

Reduce FODMAP intake by selecting low-FODMAP toppings or following a low-FODMAP diet.

Gas-Producing Ingredients

There are several gas-producing ingredients in pizza that can contribute to bloating and gas:

  • Veggies: Veggies contain a lot of fiber, which can cause bloating and produce gas.
  • Carbon dioxide: Carbonation in sodas or beer consumed with pizza can cause gas and bloating.
  • Fermentable carbohydrates: Ingredients like wheat and barley can ferment in the gut, causing gas and bloating.

By being aware of these gas-producing ingredients and choosing alternative options, it is possible to reduce bloating and gas after eating pizza.

Digestive Issues and Pizza

For many people, eating pizza results in some digestive issues that are unpleasant.

Irritable Bowel Syndrome

Irritable Bowel Syndrome (IBS) might be one cause for feeling bloated and gassy after eating pizza.

In some people, the cheese or the dough could irritate their digestive system, leading to unwanted symptoms.

If someone has IBS, they might consider avoiding certain toppings or going for a gluten-free or lactose-free pizza to see if it helps with the gas and bloating.


Gastroparesis could also contribute to these issues when eating pizza.

This condition slows down the digestive process, making it harder for the stomach to fully break down food.

Since pizza is a heavy, high-fat food, it might exacerbate symptoms like bloating and gas for folks with gastroparesis.

Small Intestinal Bacterial Overgrowth

Another reason someone could feel bloated and gassy after enjoying a slice (or four) is Small Intestinal Bacterial Overgrowth (SIBO).

This occurs when there’s a high amount of bacteria in the small intestine, causing excessive gas production.

Pizza’s high-fat and carbohydrate content might contribute to bacterial growth and cause those pesky symptoms.

Here are a few ways to help minimize SIBO symptoms:

  • Eating smaller portions
  • Reducing high-fat toppings
  • Swapping out high-carbohydrate crusts for a lower-carb option

Acid Reflux

Acid Reflux might be another factor when it comes to pizza-induced bloating and gas.

For some people, pizza ingredients like tomato sauce, garlic, and onion can trigger acid reflux, which may lead to that bloated and gassy feeling.

If someone struggles with acid reflux, they might benefit from:

  • Avoiding these trigger ingredients
  • Eating less, but more frequently
  • Avoiding lying down soon after eating

Everyone’s different, so it’s always a good idea to listen to your own body and adjust your diet accordingly.

Prevention and Lifestyle Changes

If you want to keep eating pizza, then there are a few things you can do to reduce to eliminate the bloating and gassiness.

Dietary Modifications

Sometimes pizza can make folks feel bloated and gassy ’cause of certain ingredients that they might not tolerate well.

Examples are cheese (dairy products) or wheat (gluten).

A good way to prevent these problems is by changing what they eat.

They can try a gluten-free pizza if they’re gluten intolerant, or go for a cheeseless pizza if they’re lactose intolerant.

Some people might wanna try reducing their portion sizes, too.

Chowing down on smaller amounts can help ease symptoms.

Folks could also consider watching out for common gas-causing foods like carbs, FODMAPs, and carbonated drinks.

These might be triggers for them, so being mindful of what they eat is key.

Over-the-Counter Supplements

Another way to reduce bloating and gas after eating pizza is using over-the-counter supplements that help with digestion.

Some options include:

  • Simethicone: It’s known for breaking up gas bubbles and relieving bloating
  • Lactase: This supplement can help folks with lactose intolerance digest dairy better
  • Digestive enzymes: These might help break down foods, making them easier on someone’s tummy

Lifestyle Modifications

Finally, peeps can try some lifestyle changes to feel better after chowin’ down.

Some suggestions are:

  • Chew your food slowly; it means swallowing less air
  • Avoid gum, as chewing it can also make ya swallow more air
  • Cut down on carbonated drinks; they contain carbon dioxide, which can cause gas
  • Exercise regularly; it helps with digestion and weight loss, both of which play a role in bloating and gas

Remember, if peeps are still feeling bloated or gassy even after making these changes or if they think it might be a medical condition, gettin’ some advice from a doctor is always a good idea.

Some of these symptoms might be a sign of liver disease, kidney disease, Crohn’s disease, or diverticulitis, so professional help is super important.
