I apologize if this has been mentioned (I did search but it’s kind of specific). I am three months post op so I’m entering my first summer with one kidney. I like to take walks after lunch but I’ve noticed with the hotter temps that I am so nauseous after being outside and have had a headache almost every day. I’m drinking a lot of water so I don’t think it’s dehydration. Anybody experienced this or is it unrelated to the kidney donation?
