Fibre and Haemorrhoids: How Much You Need and the Best Sources

Fibre and Haemorrhoids: How Much You Need and the Best Sources

Why Fibre Matters for Haemorrhoids

Fibre is the first thing most clinicians recommend for haemorrhoids, and for good reason. Haemorrhoids are swollen cushions of tissue in and around the anus, and one of the main triggers is straining on the toilet. Fibre makes stools softer and bulkier so they pass more easily, which reduces the pressure on those veins. It will not shrink haemorrhoids that are already large, but it can ease symptoms such as bleeding and discomfort and lower the chance of flare-ups. This guide explains how much fibre to aim for, where to find it and how to build it up comfortably.

How Much Fibre Do You Need Each Day?

UK guidance for adults is around 30g of fibre a day, and most people eat considerably less, often closer to 18g. If you are well below that, it is worth increasing gradually rather than all at once. Fibre works best alongside enough fluid, so aim to drink regularly through the day, mostly water. Fibre without enough fluid can make stools harder rather than softer.

Soluble and Insoluble Fibre: What Is the Difference?

There are two main types. Soluble fibre dissolves in water to form a soft gel, and is found in oats, barley, beans, lentils, apples and citrus fruit. Insoluble fibre adds bulk and helps food move through the gut, and is found in wholemeal bread, bran, nuts, seeds and the skins of fruit and vegetables. Most plant foods contain a mix of both, so you do not need to count each type. A varied diet is the simplest way to get what you need.

The Best High-Fibre Foods for Piles

Practical choices include porridge or wholegrain cereal at breakfast, wholemeal bread or pasta, brown rice, beans, lentils and chickpeas in meals, and plenty of vegetables. Fruit such as pears, apples with the skin on, berries, oranges and prunes is useful, and so are a handful of nuts or seeds as a snack. Swapping white versions of bread, rice and pasta for wholegrain ones is one of the easiest ways to raise your intake. Our guide to foods to avoid with haemorrhoids covers what can make symptoms worse, such as very spicy food or too much alcohol.

Do Fibre Supplements Help?

If you struggle to get enough fibre from food, a supplement such as ispaghula husk or methylcellulose can help soften stools. These are usually mixed with water or taken as sachets, and they work best when taken with a full glass of fluid. Start with a low dose and build up. Supplements are a reasonable option for some people but food is generally preferable, as it also supplies vitamins and other nutrients. A pharmacist can advise on options, particularly if you take other medicines, as fibre supplements can affect how some are absorbed.

How to Increase Fibre Without Bloating

Adding a lot of fibre quickly can cause wind, bloating and cramps. Increase your intake over two to three weeks, adding one extra high-fibre food at a time. Drink more fluid as you go, and give your gut time to adjust. If beans and pulses cause wind, start with small portions. If symptoms persist or are severe, particularly if you have a bowel condition such as irritable bowel syndrome, speak to a GP or dietitian before making big changes.

Fibre, Constipation and Straining

Hard stools and straining are the habits most linked to haemorrhoids, so fibre is only part of the picture. Go when you feel the urge rather than holding on, avoid sitting on the toilet for long periods or reading your phone, and stay active, as regular movement helps the gut. Our articles on constipation and haemorrhoids and on straining on the toilet go into this in more detail.

Can Fibre Make Haemorrhoids Worse?

For most people fibre helps, but too much too fast, or too little fluid, can bring on bloating, hard stools or loose stools, and any of those can irritate piles. If your stools become harder after increasing fibre, the usual fix is to drink more and slow down the increase. Fibre is not a cure: if haemorrhoids are large, prolapsing or keep returning despite a good diet, it is worth being examined.

When to See a Doctor

See a GP if you have bleeding from the bottom that is heavy, repeated or unexplained, a change in your bowel habit lasting more than a few weeks, pain that does not settle, or a lump you cannot explain. Bleeding is not always caused by piles, and a proper examination is the quickest way to be sure. Seek urgent help for heavy bleeding, fainting, severe pain or fever with anal swelling. Our guide on when to see a doctor about haemorrhoids sets out the warning signs.

When Diet Is Not Enough

Mild haemorrhoids often settle with more fibre, fluid and avoiding straining, sometimes with a pharmacist-recommended cream. If symptoms keep returning or are affecting daily life, there are in-clinic treatments for internal haemorrhoids that do not need a general anaesthetic. Our overview of non-surgical haemorrhoid treatments compares the main options, and our guide to haemorrhoid treatment costs in the UK sets out typical prices.

What We Offer at Our Clinics

At our clinics in Glasgow and London we examine patients and treat internal haemorrhoids with eXroid electrotherapy, which applies a low-dose direct current to the base of the haemorrhoid so that it shrinks over the following weeks, without cutting or a general anaesthetic. Of 116 patients treated at our clinics since January 2025, 84% needed only one session, although individual results vary and some people need a follow-up. A consultation with examination is £365, consultation and treatment on the same visit is £1,095, and a follow-up treatment, if needed, is £795. If what we find is not something we treat, or needs a referral for further tests, we will say so and tell you who to see.

Next Steps

If diet changes are not enough, you do not have to put up with symptoms. Our severity test takes a couple of minutes and can help you think through your symptoms, although it is not a diagnosis. You can read about our procedure or book an appointment at our Glasgow or London clinic.
