Does Drinking Water Help You Poop? A UK Guide to Constipation Relief

by Dr. Jonathan Doyle - Updated February 18, 2026
Constipation is something that almost everyone will experience at some point in their life. Having problems with bowel movements not only makes you uncomfortable but also affects your mood and daily activities.
Most people think that drinking more water could help alleviate the symptoms of constipation. But does it really work? If you are wondering, "Does drinking water help you poop?", well, you are not alone. So let’s get into the details of how drinking water could help alleviate the symptoms of constipation.

The Role of Water in Digestion

Water is a major component of body fluids and is required for almost every function in the body. Starting from the time food is chewed in the mouth, the digestive process begins.
Proper hydration is required for the following reasons:
  • Keeps stool smooth and regular
  • Helps in the muscle contractions in the intestines
  • Helps in the passage of stool through the colon
When the body is not properly hydrated, the colon absorbs more water from the stool, resulting in hard and dry stool, which is difficult to pass. Thus, the absence of proper hydration results in constipation.

Does Drinking Water Help You Poop?

The answer is a simple yes. Drinking water does help in the passage of stool. Here are the reasons how drinking water could help in the passage of stool.

Softens Stool

When the body is hydrated properly, the stool is also hydrated. As a result, the stool is easier to pass because the stool is moist and bulkier. Dehydration results in hard stool because the stool is dry and hard.

Supports Intestinal Movement

It stimulates the natural muscle contractions in your digestive tract. This process is known as peristalsis. It moves food and waste through your body.

Works Together With Fibre

The best way for water and fibre to work in your body is as a team. Fibre absorbs water and adds bulk and softness to stool. Excessive fibre without water can make constipation worse. Water helps fibre do its job.

How Much Water Should You Drink for Constipation?

The amount of water you need daily depends upon your age, body size and shape, activity level, and the climate you live in. According to many health experts in the UK, a general recommendation for adults is a daily intake of 2–2.5 litres of fluids.
If you are constipated, you can relieve constipation by increasing your water intake. It is better to drink water regularly rather than consuming a lot of water at a time.

Other Natural Ways to Relieve Constipation

Hydrating yourself is a good way to relieve constipation. It works best in combination with other healthy habits.

  • Fruits and vegetables
  • Beans and lentils
  • Whole grains
  • Oats, seeds, and nuts
It is better to increase your fibre intake gradually and drink a lot of water.

Stay Physically Active

Physical activity stimulates the muscles in your intestines. Simple physical activities like walking, stretching, cycling, and yoga can be highly beneficial in relieving constipation.

Some foods are natural laxatives. They can help relieve constipation.
  • Prunes
  • Figs
  • Flaxseeds
  • Chia seeds
  • Leafy greens

Build a Bathroom Routine

Make an effort to use the bathroom at the same time every day, especially after meals. Never ignore the need to use the bathroom. Give yourself sufficient time to relax without the need to rush.

Best Types of Water for Digestive Health

All clean and safe drinking water is suitable for digestion. Nevertheless, the majority of people in the United Kingdom prefer filtered water since it is free from the taste and smell of chlorine and other trace elements.
