IBS symptoms explained: bloating, constipation and digestive discomfort

IBS is one of those conditions that can feel confusing because the symptoms vary so much from person to person.

Some of the people I see have mostly bloating and discomfort. Others struggle more with constipation or unpredictable digestion. And some feel like it changes week to week.

I’ve had clients say to me, “I was told it’s IBS, but that doesn’t really explain what’s actually going on.” And I completely get that, because IBS is really just a label for a group of symptoms, not a single clear cause.

Common IBS symptoms

If you’ve been wondering whether IBS might apply to you, these are the symptoms I see most often:

  • Bloating after eating

  • Abdominal discomfort or cramping

  • Constipation or loose stools (or both)

  • Feeling better or worse depending on stress levels

  • Food sensitivity or fear around eating certain foods

  • A general sense that digestion just doesn’t feel “right”

You don’t need to tick every box for it to be IBS-type symptoms.

What actually drives IBS symptoms?

There isn’t one cause of IBS, which is why one approach doesn’t work for everyone.

In practice, I usually find it’s a combination of:

Gut sensitivity
Some people’s digestive systems are simply more reactive, especially after stress, illness, or antibiotics.

Food patterns and triggers
Not necessarily “bad foods”, but patterns like irregular eating, low variety, or rushed meals.

Stress and the gut-brain connection
This is a big one. I often see symptoms flare during busy or stressful periods, even if diet hasn’t changed much.

Underlying gut imbalance
Things like constipation, slow transit, or general digestive imbalance can all feed into symptoms.

Do you need to cut loads of foods out?

This is the biggest concern people come in with and the answer is usually no.

A lot of people with IBS have already tried cutting out gluten, dairy, or multiple food groups, and still feel no better long term.

Instead, I focus on understanding your patterns first, what’s actually going on in your digestion, lifestyle, and routine - before making any changes.

What support can look like

When I work with clients with IBS-type symptoms, we usually focus on:

  • Identifying personal symptom triggers

  • Supporting digestion and regularity

  • Reducing bloating and discomfort

  • Rebuilding confidence with food

  • Improving energy alongside gut health

It’s never about perfection or rigid diets — it’s about making things feel more manageable and less unpredictable.

Final thought

IBS can feel frustrating because it doesn’t always come with clear answers.

But with the right support and a more personalised approach, symptoms like bloating, constipation and digestive discomfort can often improve significantly.

If this sounds like you, this is a really common starting point for many of the clients I work with.
