At first, some patients may have cramps, nausea, vomiting, or dizziness during or just after dialysis. During the last hour of hemodialysis and for a short time after, your loved one may be tired or weak, and not think as clearly as usual. Diabetics who take insulin may find that their insulin needs change when they start dialysis. They may need to monitor blood sugar more often, even at the dialysis facility. These effects usually lessen over time.
Many patients look forward to hemodialysis once their bodies adjust to it.
Dialysis can make them feel better. Some patients schedule dialysis in the evening so they can enjoy a full day and go to bed afterwards. Even though patients may feel better after hemodialysis, many do not enjoy the treatment itself. Inserting the needles used in hemodialysis can be uncomfortable, and dialysis can be boring. That is why some patients want to cut their treatments short.
