Abdominal bloating is a relatively common condition that occurs when the abdomen fills up with gas or air. About one in six people may experience bloating, even if they don’t have any gastrointestinal conditions.

While bloating is not always a serious condition, it may cause people to feel tight or swollen, which can cause discomfort.

Some common symptoms of bloating include:

  • Excessive gas

  • Gurgling sounds from the stomach

In many cases, bloating may make everyday activities more difficult and interfere with social activities.

What causes abdominal bloating? 

Bloating may occur due to certain habits, including eating too fast, smoking, and not having bowel movements for an extended period.

There are, however, some medical issues that may cause bloating. These include:

  • Irritable Bowel Syndrome (IBS)

  • Lactose or gluten intolerance

  • Giardiasis

  • Crohn’s disease

Individuals with chronic conditions such as Crohn’s disease and IBS may experience bloating often but with proper treatments, they could reduce bloating.

How can you reduce bloating? 

Adopt a low-FODMAP diet

A low-FODMAP diet is most suitable for people with IBS and includes food that contains fermentable oligosaccharides, disaccharides, monosaccharides, and polyols. These carbohydrates are hard to digest and may remain in the colon and ferment, aiding in gas release and reducing bloating.

Try enzyme supplements

These are supplements that contain enzymes such as lactase and may help break down certain carbohydrates. 

Check if you have food sensitivities

Food allergies and intolerances may cause bloating. If you have any food sensitivities, consult a specialist and get the appropriate treatment.

Reduce the consumption of high-fibre food

Highly fibrous food may produce excessive amounts of gas. Avoiding these food items may help reduce bloating.

Have probiotics

Probiotic bacteria like Bifidobacterium lactis Bi-07 may help curb gastrointestinal problems like constipation, in turn, help reduce bloating.

Consult with your gastrointestinal specialist before following the treatments mentioned above.
