Dialysis becomes necessary when the kidneys can no longer filter waste, excess fluid, and toxins from the blood effectively. This typically happens at Stage 5 kidney disease, also known as end-stage kidney disease (ESKD), when the eGFR drops below 15. At this stage, the kidneys are either close to failing or have already failed. Here are some signs that dialysis may be approaching:
- eGFR below 15 — kidneys are functioning at very low capacity
- Severe waste buildup — toxins and fluid can no longer be removed naturally
- Symptoms worsening — such as nausea, loss of appetite, frothy urine, or skin rashes
There are two main types of dialysis to be aware of:
- Hemodialysis — blood is filtered through a machine, usually done at a center 3 times a week or at home more frequently
- Peritoneal dialysis — a cleansing fluid is delivered into the abdomen through a surgically placed tube, and can be done at home It's worth knowing that dialysis isn't a cure — it supports some kidney functions but doesn't fully replace them. A kidney transplant is another option that may be discussed with a care team, and is often the preferred long-term solution for eligible patients.
Always work closely with a nephrologist to understand when and which option is right for the specific situation.
