What Causes Our Gas to Be Smelly?

What Causes Our Gas to Be Smelly

When it comes to bodily gas, sometimes you’ll notice a distinct stench, while other times the gas is more noise than stink. So, what’s the common link between smelly gas and gas that is odorless? You.

It’s all about what you eat and what you have going on in your system. Smelly gas may seem worse or like a toxic problem that’s going to take over the world, but it’s really not that big of a deal. Although you and anybody anywhere near you might mind, smelly gas probably is just the result of something you ate.

For example, take beans. Beans are notorious for causing gas. If you eat beans, then you probably shouldn’t be too surprised to experience some gas – inside and out – while the beans move through your system. Broccoli, cabbage, onions, eggs, and meat all contain sulfur, which is quite smelly and quite responsible for causing gas.

Because of its famously unpleasant stench, sulfur is associated with rotten eggs, and you probably notice it the most when you release it. You also release other gases, including oxygen, nitrogen, hydrogen, methane, and carbon; but you’ll likely notice them less than sulfur.

Some gas is also caused by what you’re not digesting. Certain starches from carbohydrates aren’t absorbed by your system and get broken down into gas. Usually, these gases are pretty odorless. But if they mix with bacteria in your gut, they can create an odor.

Generally speaking, healthier foods cause smellier gas. But don’t shy away from eating your veggies because of this. Just know that smelly gas isn’t a sign of gastrointestinal distress or that something is wrong. It’s just the natural fermentation process taking place in your gut. Nothing to worry about.

The sound gas makes when exiting your body depends on the force of the gas and the position of your sphincter, not any foods. So although it may seem like “silent” gas is worse from a stench perspective, it’s not any better or worse from a health viewpoint.

As a marker, most people pass gas anywhere from 10 to 20 times a day. If you’re looking for a way to reduce how often you pass gas or how to make it less smelly, then consider changing your diet. Diets are really the only way to control gas; but even then, when food mingles with your own personal brand of gut bacteria, it tends to produce a very different result.

In general, a high-protein diet results in less stinky gas than a high-carb diet, but each body is unique. Sometimes, something as simple as avoiding dairy products can reduce gas in someone with a lactose sensitivity. For others, increasing protein consumption could cause more gas than following a diet that is more balanced with carbs and proteins. It all depends on your gut bacteria and what you eat.

Consider seeing a gastroenterologist if you suffer from lots of unpleasant gas, and you think that something may be wrong.
