Causes of Gas and Bloating
Gas and bloating can be caused by various factors. Swallowing air is one common cause, and this can happen when we eat or drink too quickly or when we consume carbonated beverages. Constipation is another major cause, as slow bowel movements can lead to gas retention and abdominal discomfort. The gut microbiome also plays a role, particularly when it struggles to process high-fiber foods. Lastly, our food choices can contribute to gas and bloating, with non-fermented dairy and artificial sweeteners being common culprits.
Swallowed Air and Belching
Swallowing air is a primary source of gas in our digestive system. Air that enters through the mouth is either released as burps or travels through the intestines to be expelled as gas. Factors such as frequent gulping or consuming carbonated drinks, using straws, chewing gum, or eating quickly can lead to excess swallowed air. Belching is the result of this swallowed air, which doesn't have the same odor as gas produced by the gut microbiome.
The Role of Constipation
Constipation is a significant contributor to gas and bloating. When bowel movements are sluggish, gas can build up in the intestines, leading to bloating and discomfort. Research shows that people with constipation tend to produce more bowel gas. Addressing constipation through lifestyle modifications, such as increased fiber intake and staying hydrated, can help alleviate gas and bloating symptoms.
Most of us are familiar with the unpleasant feeling of being bloated. It can happen after eating specific foods or when you experience slower bowel movements. Sometimes, it can be a symptom of an underlying health condition.
To take a closer look at issues related to gas and bloating, we’ve invited a special guest this week: superstar gastroenterologist and Zoe’s US Medical Director Will Bulsiewicz.
In today’s short episode of ZOE Science & Nutrition, Jonathan and Will ask: what are the main causes of gas bloating and how do we stop it?
