Reasons Why You Might NOT donate a kidney
Your medication requirements aren't compatible
After donating a kidney, you may have to change the medication you take to minimize stress on the remaining kidney. For instance, all kidney donors are supposed to avoid NSAIDs like ibuprofen, Aleve and aspirin, and to take Tylenol (acetaminophen) instead. You may also have other medications (including psychiatric meds) that would need to be changed.
If you aren't able to take Tylenol or find substitutes for other medications, it may be worth thinking long and hard about whether donation is right for you. Your physician and psychiatrist will be able to give you more information if needed.
You're scared of needles or blood
You will get your blood drawn a lot in the process of donating an organ, and may also get an IV drip after surgery.
You're nervous about surgery
That's valid! All surgeries and anesthesia do carry risks. The risk of long-term complications from donating a kidney is very low, but it's your body and your choice, period.
Your family has a history of kidney disease, or you already have just one kidney.
Some people are born with only one! Or if you think there's a good chance you'll need two, it's totally rational not to donate one.
You've had issues with painkiller addiction in the past
After surgery, you may have a morphine or fentanyl drip in the hospital, and you're likely to be prescribed an opioid painkiller. The amount of painkillers is normally not enough to create a physical dependency. But for some people in addiction recovery, this may still be concerning.
If this worries you, I highly recommend discussing this topic with your physician and the surgeon, and following their advice. Medical professionals in the USA cannot report you to law enforcement for using illegal substances.
Any other medical conditions that make you a bad candidate
Your own health is important, and it might also affect whether your kidney would be viable in someone else's body.
You'll get scanned to hell and back during the screening process, so if there's any medical issues that would get in the way, the transplant team will tell you. They will NOT remove your kidney if they believe the surgery or loss of the kidney could harm your health later.
You want to make a connection with someone
Yeah...don't go into this process expecting it to change your life, or win you lots of praise, or hoping to meet the recipient (if you donate to a stranger like I did). What if your recipient turns out to be someone you don't like? What if you stay in touch but the kidney fails after a few years? What if you were hoping to feel better about yourself, but a month after surgery you realize you're still the same old you?
(Personally, I do feel like it changed my life for the better, and some people do form strong relationships with their recipient after the transplant. But people can have a lot of different reactions. Nothing is guaranteed.)
I chose not to contact or receive contact from my recipient, or to hear follow-up reports of how they were doing. I didn't want them to feel indebted to me, or for me to unwittingly place expectations on them. You might choose differently, which is valid - but make sure you'd be okay with not ever hearing from the recipient, too.
This isn't always a hurdle. If you donate through the National Kidney Registry, for instance, they'll try to compensate you for any lost wages during your surgery and recovery period. You won't bear the cost of surgery or follow-up appointments, either. At least, that's how it is in the USA.
However, I did have to take time off work to go to the pre-surgery appointments. I did have to buy extra groceries for before and after the surgery, an abdominal binder and robe, and a few other costs. If I get medical complications later in life, I will have to pay for those either out of pocket or with health insurance. These may still be serious considerations for you.
You can't take enough time off to recover
My surgery team recommended two weeks off work - even though I work from home. They also wanted me to have someone present to drive me to and from the hospital, and to stay with me for the first few days after surgery. Your own job, childcare needs, or transportation/living assistance needs may impact your ability to do this.
You just plain don't want to
As I said, it's your body, your choice. You never, ever have to undergo surgery and give away part of your body for someone else. Even if you love that person and they're in pain. A donated organ should be a gift given freely, and gladly, not a source of fear or worry for you.
If you aren't able or willing to donate yourself, there are still many ways you can help people in need:
You could donate blood or plasma, which regenerate over time and don't require surgery.
You could help a prospective kidney donor by offering childcare while they're in the hospital, transportation assistance, or helping them recover after surgery.
You could register as an organ donor on death, so that your body isn't affected at all while you're alive. In the USA, only 60% of adults are registered as organ donors even though 90% support postmortem organ donation.
You can spread awareness of how organ donation works! Many people don't realize that they can donate a kidney, even without an intended recipient. Or they might believe it's more dangerous or debilitating than it actually is. By sharing educational resources about it, you can still increase the likelihood of more patients getting kidneys.
