My mom is a dialysis patient for over 3 or 4 yrs. I just don t like to remember;( my question is this lately her stomach has grown but she is retaining too much fluidly lately about a month ago she hurt her leg causing a sore to not heal. Just today after dialysis her leg started to throb with excruciating pain and I know it s because her legs are swollen.. She weighed in today at 69.8 and when she did her 4 hrs she was 67.4.. What is going on? Should I worry? Or is this normal.. I went to her general doctor and they said, it s part of the dialysis. I almost didn t like the answer. Even the discoloration in her legs is getting worse. I noticed her fistula sight has 2 moused sized bumps and we have had them checked. But why did they get this way and why didn t the techs prevent them from happening? What should I do?

### output:

Hello, kidneys main function as you know is producing urine which is not happening right now. So in between the dialysis sessions, the fluid accumulates in body as it can't be excreted out due to decreased function of kidney. I would suggest that her daily fluid intake should not exceed 800 ml to 1000 ml. by doing this you reduce the amount of fluid she takes in thus reducing fluid accumulation. Now about the bumps in fistula site, there is fistula formation between artery and vein at that site. This causes direct blood flow from artery to vein in that particular area. As veins can't sustain the pressure of arterial blood flow in them directly, they distend which causes bump formation. This is seen commonly in patients undergoing dialysis so no need to work about it. I hope I have answered your questions. Thank you
