Staying Hydrated with IBD: Why It Matters More Than You Think
Living with Crohn’s Disease or Ulcerative Colitis brings daily challenges, from managing flare-ups to navigating fatigue and dietary changes. One often overlooked but vital aspect of managing IBD is hydration. For people with IBD, staying properly hydrated isn’t just about quenching thirst—it’s a key part of maintaining health and preventing complications.
Why Are People with IBD More Prone to Dehydration?
People with IBD are at a higher risk of dehydration due to:
- Frequent diarrhoea – a common symptom during flare-ups, leading to rapid fluid and electrolyte loss.
- Vomiting – especially during active disease phases.
- Surgical changes – such as a stoma (e.g. ileostomy) or J-pouch, which can reduce fluid absorption.
- Medication side effects – including diuretics or laxatives that increase fluid loss.
Signs You Might Be Dehydrated
Watch out for these early signs:
- Thirst or dry mouth
- Dark yellow or strong-smelling urine
- Headaches or dizziness
- Fatigue or confusion
- Dry or cracked lips and skin
Remember: Severe dehydration is a medical emergency. Symptoms like rapid heartbeat, extreme thirst, and confusion require immediate medical attention.
How Much Should You Drink?
While the general recommendation is 6 to 8 glasses of fluid a day (about 1.2 litres), people with IBD may need more—especially during:
- Hot weather
- Illness or fever
- Flare-ups
Water is best, but diluted squash, herbal teas, and oral rehydration solutions (ORS) can also help.
Tips for Staying Hydrated
- Carry a water bottle and sip throughout the day
- Set reminders or use hydration tracking apps
- Avoid excessive caffeine and alcohol
- Use ORS during diarrhoea or vomiting to replace lost salts and sugars
- Special Considerations for Those with a Stoma
- If you have an ileostomy, your body may not absorb fluids as efficiently. You may need:
- Increased fluid intake
- Specialist ORS with higher sodium content
Always follow your IBD team’s advice on fluid and salt replacement.
Final Thoughts
Hydration is a simple yet powerful tool in managing IBD. By staying on top of your fluid intake, you can:
- Reduce the risk of complications
- Support your body’s healing
- Feel more in control of your condition
If you're unsure about your hydration needs, speak with your IBD nurse, Stoma nurse or gastroenterologist. And remember—don’t wait until you’re thirsty to drink. Your body (and your gut) will thank you.
