Essential Steps & Tips | Rapidcare
Living with an ostomy changes many things- and hydration is one of them. We spoke to Jill, one of our stoma care nurses, to better understand how staying can help people with a stoma feel more comfortable, energetic, and in control. In this article, she shares practical tips and signs to look out for- plus how to spot when your body might be running low on fluids.
Why hydration matters when living with an ostomy
"We often underestimate the role of water in our bodies, especially when living with an ostomy," says Jill, who's supported hundreds of patients through their stoma journeys.
If your large intestine has been partially or fully removed, your ability to absorb water may be reduced. Around 20-30% of our water absorption usually happens in the large intestine - so it's not just about drinking more, but understanding how your body handles it.
How much should I drink?
According to the Ostomy Nutrition Guide from the University of Rochester Medical Center, most people with an ostomy should aim for at least 8 cups of fluid daily. That amount can change depending on:
How much output you're passing
The weather (hot days need more!)
Your activity level
Spot the signs of dehydration early
One of the most important things Jill highlighted was recognising dehydration before it becomes serious. Keep an eye out for:
Headaches
Dizziness or light-headedness
Fatigue
Dark Urine
Dry Mouth
"Muscle cramps or a racing heart can be signs your body's struggling to keep up," she explains." Act early- top up your fluids and rest if needed."
What causes dehydration with a stoma?
There are lots of potential causes, including:
Not drinking enough throughout the day
Vomiting or diarrhoea
Hot weather or exercise
Medications that act as diuretics
Foods or drinks that increase output(like caffeine or alcohol)
Easy ways to stay hydrated
She also gave us her top strategies for supporting hydration with an ostomy:
Sip fluids slowly and regularly - especially between meals.
Add electrolytes- sodium and potassium help your body retain fluids
Include salty snacks- things like crackers or pretzels can help
Limit fluid during meals- to avoid diluting digestive enzymes
What to avoid with an ostomy
Some foods and drinks can lead to unpredictable output or irritation. These may include:
Sweets and artificial sweeteners
Alcohol and caffeine
Frizzy drinks
Dairy (if you're sensitive to lactose)
Nuts, seeds, and high-fibre veg
Whole grains like bran or popcorn
Legumes, beans, and lentils
Everyone's different, so tracking how your body reacts can really help.
