What's causing your bloating? Common causes and what to look for
Bloating is one of the most common concerns I hear about in practice.
It can be uncomfortable, frustrating and, for some people, something they experience most days. Often, people arrive convinced that a particular food must be the cause, and that identifying the culprit will solve everything.
Sometimes that is the case.
More often, however, the picture is a little more complex.
Bloating can be influenced by a range of factors, including eating habits, digestive function, bowel movements, stress, hormones and lifestyle. That's why understanding the bigger picture is often more helpful than simply removing foods and hoping for the best.
What exactly is bloating?
Bloating is the feeling of fullness, pressure, tightness or swelling in the abdomen.
For some people, it's something they notice after certain meals. For others, it gradually builds throughout the day. Some experience discomfort alongside changes in bowel habits, while others struggle to identify any obvious trigger at all.
Although bloating is common, it's not necessarily something you should ignore or simply learn to live with. It can be a valuable clue that helps us understand what's happening within the body.
It may not be what you're eating, but how you're eating
When we think about digestion, we often focus on food.
Yet how we eat can sometimes be just as important.
Eating quickly, rushing between meetings, not chewing thoroughly, drinking through a straw or talking while eating can increase the amount of air we swallow. This may contribute to bloating and discomfort.
Large meals can also leave us feeling uncomfortably full, particularly if digestion already feels sluggish.
Sometimes, it's not just what you eat, but how you eat that matters.
Certain carbohydrates naturally produce more gas
Some carbohydrates are fermented by bacteria in the large intestine, producing gas as a normal part of the digestive process.
Foods such as onions, garlic, legumes, certain fruits and wheat-based products are common examples.
These foods are often highly nutritious and play an important role in a balanced diet. However, some people may find they tolerate them differently, particularly during periods when digestion feels more sensitive.
Rather than labelling foods as "good" or "bad", I prefer to focus on understanding individual patterns and tolerance.
Constipation is often overlooked
When people think about bloating, constipation isn't always the first thing that comes to mind.
However, it is something I explore with many clients.
If bowel movements are infrequent, incomplete or difficult to pass, stool and gas can build up within the digestive tract, leading to feelings of heaviness, pressure and bloating.
If bloating is accompanied by irregular bowel movements, this may be an important piece of the puzzle.
Even healthy changes can cause bloating
One thing I often see is people trying to improve their health by dramatically increasing fibre intake.
Adding more vegetables, legumes, seeds and wholegrains can absolutely be beneficial, but introducing large amounts too quickly isn't always well tolerated.
The digestive system often needs time to adjust.
When it comes to fibre, a gradual approach is usually more comfortable than an overnight transformation.
Don't forget about stress
Digestive health isn't only about what we eat.
The gut and brain are constantly communicating with one another, which means periods of stress can have a noticeable impact on digestion.
Some people find their appetite changes when they're stressed. Others notice shifts in bowel habits or increased digestive discomfort.
This doesn't mean symptoms are "all in your head". Rather, it highlights how closely connected our digestive system and nervous system really are.
When exploring bloating, it's important to consider stress alongside nutrition and lifestyle factors.
Hormones may play a role too
Many women notice changes in digestion throughout their menstrual cycle.
Hormonal fluctuations can influence fluid retention, bowel habits and digestive comfort, making bloating more noticeable at certain times of the month.
Tracking symptoms alongside your cycle can sometimes reveal patterns that might otherwise be easy to miss.
A Practitioner's perspective
One of the most common mistakes I see is people removing more and more foods in an attempt to solve bloating.
While food triggers can certainly play a role, excessive restriction doesn't always provide the answers people are looking for.
Before eliminating foods, I usually encourage people to take a step back and look at the wider picture.
Ask yourself:
When does the bloating occur?
Does it build throughout the day?
How are your bowel movements?
Are you eating on the go or rushing meals?
Have stress levels been higher than usual?
Do you notice patterns around your menstrual cycle?
Often, these questions provide valuable clues that are worth exploring further.
Final thoughts
Bloating can feel confusing, especially if you've already tried changing your diet without seeing the improvements you were hoping for.
The good news is that bloating is often a clue rather than something you simply have to put up with.
Sometimes the answer is food-related. Sometimes it's linked to eating habits, constipation, stress, hormones or lifestyle. More often than not, it's a combination of several factors.
The goal isn't to chase perfection or endlessly remove foods from your diet.
It's to better understand your body, identify patterns and uncover the areas that may need a little more support.
