Why am I constantly gassy?

Constantly gassy?

Is being constantly gassy is a problem you need to address, or just a healthy biproduct of good gut bacteria doing their thing? The frustrating answer is both, but there are definetely ways you can assess it with more nuance. 

Gas-producing bacteria in the gut are a normal and natural part of the gut microbiome. These bacteria ferment undigested carbohydrates that pass through the digestive system, producing gases such as hydrogen, methane, and carbon dioxide as byproducts.

Some of the main types of gas-producing bacteria in the gut include:


These are a group of gram-negative bacteria that are commonly found in the gut. Bacteroides species are known to produce hydrogen and other gases during carbohydrate fermentation.

Clostridia: Clostridia are a diverse group of gram-positive bacteria that are also commonly found in the gut. Some species of Clostridia are known to produce hydrogen gas and other gases during fermentation.


These are a group of gram-positive bacteria that are commonly found in the gut and are often used as probiotics. While lactobacilli are generally considered beneficial, some strains have been found to produce gas during fermentation.


These are a group of archaea that produce methane gas as a byproduct of fermentation. Methanogens are present in small numbers in the gut, but their overgrowth has been linked to conditions such as SIBO.

While gas-producing bacteria are a normal part of the gut microbiome, being constantly gassy can be a symptom of gut dysbiosis or other gastrointestinal disorders. In these cases, interventions aimed at restoring microbial balance, such as probiotics or dietary changes, may be helpful in reducing gas production and related symptoms.

Differentiating between “good” and “bad” gas:

This can be difficult since there isn’t a clear definition of what constitutes “good” or “bad” gas. However, there are certain cues that can indicate potential issues or imbalances in the gut microbiome.


The odor of gas can vary depending on the types of gases produced and the composition of the gut microbiome. Generally, foul-smelling gas may indicate the presence of sulfur-producing bacteria like Desulfovibrio or an overgrowth of certain species.

Pain or discomfort:

Excessive gas production can lead to bloating, abdominal pain, and discomfort. These symptoms may indicate an underlying medical condition, such as IBS or SIBO, and should be evaluated by a healthcare professional.

Irregular bowel movements:

Changes in bowel movements, such as constipation or diarrhea, may also indicate an imbalance in the gut microbiome or an underlying medical condition.

Frequency and duration:

The frequency and duration of gas production can also provide insights into gut health. Excessive or persistent gas production may indicate an issue with the gut microbiome or an underlying medical condition.

It’s worth noting that everyone’s gut microbiome is unique, and what may be considered “good” or “bad” gas can vary from person to person. Additionally, many factors can influence gas production, including diet, stress, medication use, and underlying medical conditions.
