I Eat the Healthiest in My Family. So Why Am I Still Constipated?

You eat your vegetables. You choose wholegrain bread, add seeds to your breakfast and probably think more about fibre than anyone else in your household.

So why are you still struggling to poo?

If you're eating what you consider a healthy diet but still dealing with constipation, it can be frustrating to hear the same advice over and over again: eat more fibre, drink more water and get moving.

These habits can help, but constipation isn't always as simple as eating more fibre. Your bowel habits are influenced by several factors, and even a nutritious diet doesn't guarantee comfortable, regular bowel movements.

If you're already eating well but still constipated, it might be time to look beyond how much fibre you're eating and consider the type, your symptoms and what else could be going on.

What does constipation actually look like?

Constipation isn't just about how often you go to the toilet. You might be constipated if you:

• Pass hard, dry or lumpy stools.

• Need to strain to pass a bowel movement.

• Feel like you haven't completely emptied your bowel.

• Find it difficult or uncomfortable to pass stool.

• Go less often than is normal for you.

Some people have a bowel movement every day and still experience constipation because passing stool is difficult or they don't feel fully emptied. Others go less frequently without experiencing discomfort.

The important thing is to consider the whole picture, not just the number of times you poo each week.

Why might you still be constipated if you eat well?

Fibre plays an important role in bowel health, but it isn't the only factor affecting how comfortably you go.

Your fluid intake matters. Fluid helps support normal stool consistency. If you're increasing your fibre intake, adequate fluid is particularly important, although drinking more water alone won't resolve every case of constipation.

Your routine can make a difference. Travel, stress, changes in activity and ignoring the urge to go can all affect bowel habits. Giving yourself time to use the toilet when you feel the urge may help.

Medications and supplements can contribute. Some medicines, including certain pain medicines, and supplements such as iron can cause constipation. Don't stop prescribed medication without speaking to your healthcare professional.

Your pelvic floor may be involved. The muscles that help you pass stool need to coordinate and relax appropriately. If they don't, you may experience straining, difficulty emptying or a persistent feeling that stool is still there, even when you're eating enough fibre.

Health conditions can also affect bowel function. If constipation is ongoing, particularly if you're experiencing significant straining or difficulty emptying, it's worth discussing this with your GP rather than continually adding more fibre.

Could the type of fibre you're eating make a difference?

If you've been focusing on eating more fibre, you might assume that all high-fibre foods will help your bowel movements in the same way.

They don't.

Some fibres contribute to stool BULK, some form a GEL by absorbing water, and other FEED fibres are fermented by gut bacteria. These properties can overlap, and different fibres have different effects.

If you're passing hard stools, one option worth exploring is GEL fibre, which can help retain water and support stool consistency.

This doesn't mean GEL fibre is the answer for everyone with constipation. But understanding what it does can help you make more informed choices about the foods and products you try.

GEL fibre: helping support stool consistency

GEL fibre absorbs water and forms a soft, gel-like substance in your digestive system. Depending on the type and amount, it can help soften stools and make them easier to pass. Some GEL fibres can also help regulate stool consistency when stools are too loose.

You can find GEL fibre in foods and ingredients such as:

• Oats, which contain beta-glucan, a soluble fibre.

• Chia seeds, which absorb liquid and develop a gel-like coating.

• Ground linseed (flaxseed), which provides a mixture of fibre types.

• Psyllium husk, a GEL fibre with evidence supporting its use for some types of constipation and irritable bowel syndrome (IBS).

These options aren't interchangeable, and adding more isn't necessarily better. Psyllium, in particular, has been studied for its ability to improve stool frequency and consistency in some people. If you're considering a psyllium supplement, follow the product directions and take it with adequate fluid. Check with your pharmacist or dietitian if you're unsure whether it's suitable for you.

What could this look like in everyday life?

You don't need to overhaul your diet or add every fibre source at once. Start by looking at what you already eat and whether a small, manageable change might suit your symptoms.

For example:

Breakfast: overnight oats with rolled oats, milk or lactose-free milk, chia seeds and yoghurt, topped with kiwi fruit.

Snack: yoghurt with a little ground linseed and your preferred fruit.

Easy addition: stir oats into porridge or add them to homemade muffins.

Kiwi fruit is also worth considering. Research suggests it may help improve constipation for some people, although its benefits aren't solely explained by GEL fibre.

If you're increasing fibre, do so gradually and pay attention to how your symptoms respond. You don't need to introduce several new foods at once to make progress.

What if you've already tried eating more fibre?

If you've already increased your fibre intake and nothing has changed, resist the urge to keep adding more without considering the bigger picture.

Think about what you're experiencing. Are your stools hard? Are you straining? Do you feel as though you can't fully empty your bowel? Or are you going regularly but still feeling bloated and uncomfortable?

These differences matter because they can point towards different contributors to your symptoms.

For some people, adjusting the type or amount of fibre may help. For others, medication, pelvic floor dysfunction, an underlying health condition or another factor may need to be addressed.

You don't need to keep experimenting with your diet indefinitely. An Accredited Practising Dietitian (APD) can help you review your intake and symptoms, while your GP can investigate possible medical causes.

Your questions about fibre and constipation

How much fibre should I eat if I’m constipated?

In Australia, the general recommendation for adults is around 25g of fibre a day for women and 30g for men, although everyone’s needs are a little different.

Hitting a number doesn’t guarantee comfortable, regular poos, though. The type of fibre you eat matters too, along with how much water you drink and anything else affecting your bowels. If you’re already eating plenty of fibre, adding even more may not be the most helpful next step. Looking at whether you’re getting the right mix of GEL, BULK and FEED often is.

Is soluble fibre better than insoluble fibre for constipation?

Neither is better across the board, and the labels can be confusing. Psyllium and inulin are both soluble fibres, for example, but they behave very differently in your gut. Psyllium forms a GEL that helps soften and regulate your poo, while inulin FEEDS your gut microbes and can mean more gas. Most insoluble fibre adds BULK, which helps keep things moving.

That’s why I use GEL, BULK and FEED instead. They tell you what a fibre does in your gut, not just whether it dissolves in water. What works best for you depends on your symptoms, the fibre itself and how your gut responds. If your gut is already grumpy, the order you add them in matters too.

When should I see a doctor about constipation?

Speak with your GP if constipation is persistent, keeps coming back, or isn’t improving with reasonable changes to your routine. See your GP promptly if you notice blood in your poo or unexplained weight loss. Severe or worsening tummy pain, vomiting, or not being able to pass a poo or wind needs urgent medical attention.

Want to make sense of fibre for your gut?

Eating well and still being constipated can leave you wondering what you’re missing. And you probably don’t need another list of foods you’re “supposed” to eat.

Understanding the three jobs fibre does is a great place to start. That’s why I created my free Fibre for Grumpy Guts starter guide. It explains GEL, BULK and FEED, and the simple one-week gel test I start my clients with.
