💩 Constipation and Ondansetron - Sunday Support 🫶
If you are currently taking, or have previously taken Ondansetron, you may well be aware of one of its most common (and frustrating) side effects.
Constipation.
When you’re already dehydrated, weak, and barely functioning from non-stop nausea/vomiting, dealing with painful, stubborn constipation is just one more thing and many factors that HG sufferers face just don’t help – e.g. having a very limited diet, reduced fluid intake and being bedbound.
A few things that might help:
🔸Hydrate as much as you can – easier said than done, but sips of fluid, ice lollies/ice pops, and any foods high in water content that you can manage may help to reduce symptoms.
🔸Add in fibre when tolerated – things like pears or prune juice, smoothies and whole grains.
🔸Gentle movement (if possible) – this can be as much as light stretching or a gentle walk.
🔸Ask your doctor or pharmacist about pregnancy safe stool softeners or laxatives. Some laxatives require water intake to work effectively, so it’s important to discuss the safest option with a medical professional and address any symptoms of dehydration.
🔸If things worsen, don’t hesitate to seek medical help.
