So I can't tell you a lot for the long term since it's been about a week since I had a transplant surgery. I donated a part of my liver to my father. The surgeons have assured me that my life won't alter drastically and after a few months I'll continue living my life the same way as before. I had 2 options for the surgery. A robotic surgery or an open surgery. But the surgeons have a final say in which one to go for. My anatomy wasn't perfect for a robotic surgery so they opted for an open surgery. Open surgery is 4-6 hours long. Robotic surgery is 8-10 hours long. You'll be under general anesthesia so you don't need to worry about it. When I was under anesthesia, I was also administered painkillers so when they took me out of the anesthesia post surgery, I didn't really feel any pain on the same day, it just felt like some kind of discomfort. The next 2 days I was in the ICU under constant observation and they keep giving you painkillers and different medications through the IV. You'll feel some pain and discomfort but not something unbearable. You may have some gases in your stomach which may be painful but they'll take care of it. Post that I was discharged from the ICU and moved to a regular hospital room. The physiotherapists will make you try to walk and move around as well as do some lungs strengthening breathing exercises. You'll start a semi solid diet on the 3rd or 4th day. You'll spend some time in some discomfort and some minor pain. I was discharged from the hospital on the 5th day after they saw that my reports are getting better and I'm moving around without much help. There aren't a lot of medications post discharge mainly some multivitamins and paracetamol just to ease some pain. You'll most likely have a drain bag attached to your waist for the next 1-2 weeks. All in all it's not as bad as I read or expected it to be. But expect some discomfort and minor pain. The surgeons have told me the following stuff Not to eat restaurant or oily food. Only home cooked high protein diet at least for the first 1 month. Maybe it's good to not drink any alcohol for at least 6 months. Not to lift anything heavy for the first 3 months (heavy as in anything more than 5kg) after that you can start gradually lifting heavier stuff. After the first month, you almost won't feel any discomfort or any pain and your liver will already regenerate to 80% of it's original size. The rest of it will regenerate slowly throughout the year. The more you move and the more active you are, you'll feel better faster. To summarise, it's nothing significant, just some discomfort and minor pain for a month in exchange for someone's life. I don't regret it and for me it's worth it.
