Health experts warn against misinformation on dialysis, emphasise evidence-based kidney care

Health professionals have raised concern over the growing spread of misleading claims about kidney disease treatment, particularly assertions circulating on social media that dialysis weakens or damages the kidneys and that “detox” diets can serve as alternatives to medical care.

Dialysis, according to nephrologists, does not heal damaged kidneys nor does it further weaken them.

Instead, it is a life-sustaining medical procedure designed to perform essential functions—such as removing waste products and excess fluid from the blood—when the kidneys can no longer do so adequately.

Medical experts often describe dialysis as a supportive therapy, not a cure, used in cases of advanced kidney failure to keep patients alive and stable.

Reacting to claims that dialysis merely “outsources” kidney functions to machines, specialists explain that the treatment becomes necessary only after significant and often irreversible loss of kidney function.

“Dialysis does not cause kidney failure; it is prescribed because kidney failure has already occurred,” a Lagos-based nephrologist noted. “Without it, many patients with end-stage renal disease would not survive.”

Experts have also cautioned against unverified recommendations that promote detoxification through water, fruits, or vegetables as a treatment for kidney disease.

While balanced nutrition and adequate hydration are important for general health, doctors stress that so-called detox regimens have no scientific proof of repairing damaged kidneys.

In some cases, excessive intake of certain fruits or fluids can even be harmful to kidney patients, depending on their condition.

Medical practitioners agree, however, that lifestyle choices play a critical role in kidney health. Unhealthy diets high in processed foods, excessive salt, preservatives, and sugary drinks, as well as smoking and unmanaged high blood pressure or diabetes, are known risk factors for kidney disease.

Patients are therefore encouraged to adopt healthier eating habits, focus on natural and minimally processed foods, and follow medically approved dietary plans tailored to their condition.

Healthcare professionals advise individuals living with kidney disease to seek guidance from qualified doctors and dietitians rather than relying on social media advice.

“Lifestyle changes are important, but they should complement—not replace—medical treatment,” an expert emphasized.
