Frequently Asked Questions
I have IBS-D (diarrhea type) - can I still donate?
Yes, but time your donation for when your symptoms are well-controlled. Urgent bathroom needs during donation are problematic since you can't easily disconnect mid-donation.
What if I need the bathroom during donation?
You can request a pause, but it requires stopping the machine and may extend your visit. It's better to donate when you're confident you won't need a break.
Will the stress of donation trigger my IBS?
It might. Many people with IBS have stress-related symptoms. If you're anxious about donating, that could trigger symptoms. Bring headphones and something relaxing to watch.
