Dialysis is neither inherently good nor bad; it's a life-sustaining treatment for kidney failure, but its benefits and drawbacks depend on individual circumstances and overall health.
Here's a breakdown to help understand:
-
When Dialysis is Good:
- Kidney Failure Support: Dialysis effectively removes waste products and excess fluids from the blood when the kidneys can no longer perform these functions. This addresses the immediate, life-threatening consequences of kidney failure. Dialysis can significantly improve symptoms caused by kidney failure.
- Symptom Relief: By filtering the blood, dialysis can alleviate symptoms like nausea, vomiting, swelling, fatigue, and shortness of breath, which are common in kidney failure.
-
When Dialysis Might Not Be the Best Option or Could Be Considered "Bad":
- Underlying Health Conditions: In individuals with significant pre-existing health conditions like stroke, Parkinson's disease, peripheral vascular disease, frailty, or dementia, dialysis may not address the root cause of their symptoms and can even worsen their overall condition. Dialysis will not help with the symptoms caused by these other diseases.
- Quality of Life Considerations: Dialysis can be a demanding treatment, requiring frequent and lengthy sessions. This can impact a person's quality of life, limiting their ability to travel, work, or participate in social activities.
- Physical Strain: The dialysis procedure itself can put a strain on the body, especially for frail or elderly individuals. Side effects like low blood pressure, muscle cramps, and infection are possible.
- Not a Cure: Dialysis is a treatment, not a cure. It manages the symptoms of kidney failure but doesn't restore kidney function.
Ultimately, the decision of whether or not to pursue dialysis is a complex one that should be made in consultation with a physician, nephrologist, and loved ones, considering all aspects of a patient’s health and quality of life. If kidney transplant is an option, it should be explored.
