Constipation: why you're stuck and what actually helps

By The FixMyGut team · Published · Updated · 4 min read

Day three. Nothing. You’ve tried coffee, prunes and staring meaningfully at the bathroom door. Constipation is incredibly common and usually easy to manage, but it can make you feel heavy, bloated and grumpy. (Part of gut health basics.)

What counts as constipation?

According to the NHS, you’re probably constipated if:

  • you haven’t pooped at least 3 times in the last week, or you’re going less often than usual
  • your poop is dry, hard or lumpy
  • it’s unusually large or small
  • you’re straining, or it feels like you haven’t fully emptied

On the Bristol stool chart, constipation usually looks like type 1 (hard lumps) or type 2 (lumpy sausage).

What causes it?

The NHS and NIH list the everyday culprits:

  • not enough fiber, or not enough fluids
  • not moving much
  • ignoring the urge to go (we see you, office loo avoiders)
  • changes in routine: travel, shifts, a new job
  • some medicines, and iron supplements
  • stress or anxiety
  • pregnancy

What helps constipation at home?

Things to try for a week

  • Add fiber gradually: oats, wholegrains, fruit, veg, a spoon of linseed or wheat bran
  • Try fruits with sorbitol, like apples, apricots, grapes or raspberries
  • Drink more fluids, especially water
  • Walk or move more each day
  • Keep a regular time and place to go, and don't ignore the urge
  • Rest your feet on a low stool so your knees are above your hips
  • Ask a pharmacist about laxatives if needed

The NHS notes that laxatives from a pharmacy usually work within 3 days. If your constipation is regular, a GP can help find out why.

A simple toilet routine

The NIDDK suggests trying to have a bowel movement at the same time each day, for example 15 to 45 minutes after breakfast, because eating helps your colon move stool. The NHS adds: don’t delay when you feel the urge, give yourself time, and try resting your feet on a low stool so your knees are above your hips. Details in how to sit on the toilet.

Constipated away from home?

The NIDDK lists travel among routine changes that can bring on constipation. Our travel constipation guide covers water, fiber and timing on the road.

What about laxatives?

The NHS recommends trying diet and lifestyle changes first, and a pharmacist can help you choose a laxative. Our plain-English laxatives explainer covers the four main types the NHS describes.

How can tracking help?

Constipation is all about frequency and form, which are the two things a log captures best. Over a couple of weeks you’ll see your real rhythm, which foods or routines line up with harder days, and whether changes are helping.

Mon  no poop  (travel day, little water)
Tue  no poop
Wed  09:10  type 1
Thu  08:40  type 3  (added porridge + linseed Tue)

More in constipation tracking and how often should you poop.

When should I see a GP about constipation?

The NHS says see a GP if you’re regularly constipated or bloated, it isn’t getting better with treatment, you’ve lost weight without trying, there’s blood in your poop, you feel tired all the time, you notice a sudden change in your bowel habits, or you have tummy pain. If a medicine might be the cause, talk to the GP before stopping it.

Wrap-up

Constipation usually responds to the basics: fiber, fluids, movement and not ignoring the urge. Give changes a week or two and keep notes. If you’re stuck for longer, it’s time for professional help, not more prunes.

Quick answers

How long is too long without pooping?

The NHS describes constipation as going fewer than 3 times in a week, or less often than usual for you. See a GP if it isn't improving.

What helps constipation quickly?

A pharmacist can recommend a laxative, and the NHS says most work within 3 days. Fluids, fiber and a walk help too.

What foods help constipation?

Fiber-rich foods such as oats, wholegrains, fruit, vegetables and linseed, plus plenty of fluids. The NHS also suggests fruits containing sorbitol, such as apples, apricots, grapes, raspberries and strawberries.

Which Bristol types mean constipation?

Types 1 and 2 are the hard, lumpy end of the scale. The NHS England chart describes types 3 and 4 as what healthy poo looks like, and says a poo that doesn't look like type 3 or 4 could be constipation.

Can constipation cause bloating?

Yes. The NHS lists constipation as a common cause of bloating.

Does drinking more water help constipation?

The NHS says fiber needs fluid to do its job. See [water and poop](/blog/water-and-poop).

Why do I feel like I still need to go after pooping?

That feeling is called tenesmus. It can happen with constipation and also with inflammation or infection, so mention it to a GP if it continues. See [feeling like you still need to poop](/blog/feeling-like-you-still-need-to-poop).
