For patients with chronic hemodialysis, maintaining an optimal level of phosphorus in the blood is essential. An elevated phosphorus level can lead over time to:
- blood vessel damage
- heart problems
- bone fragility
- persistent itching and discomfort
Within the doctoral research conducted by Dr. Andra Balcangiu-Stroescu, three important factors influencing serum phosphorus levels were analyzed: diet, physical activity, and the disease that led to the development of chronic kidney disease.
1. What do dialysis patients actually eat?
To better understand dietary habits, consumption patterns of hemodialyzed patients were analyzed and compared with recommendations from the "phosphorus pyramid" — a model that shows which foods should be limited and which can be consumed more safely.
The result?
Clear differences were discovered between:
- what we recommend from a medical perspective
- what actually ends up on the plate
Often, phosphorus-rich foods are consumed without the patient knowing they can increase lab values. This is where personalized nutritional education plays a role.
Phosphorus control does not mean "strict prohibitions," but understanding the correct choices.
2. Can movement influence phosphorus?
Yes. And more than we would have expected.
In the study conducted, patients who combined a controlled diet with physical activity adapted to their tolerance level (regular walking, light exercises, constant movement) showed better phosphorus values.
Movement helps with:
- improving metabolism
- more efficient nutrient utilization
- balancing important metabolic parameters
Even moderate physical activity, adapted to each patient, can make a difference.
3. Does it matter if the patient has diabetes?
Another important aspect analyzed was the influence of the disease that led to chronic kidney disease.
It was observed that after 6 months of strictly controlled diet:
- patients with diabetes generally had higher phosphorus values compared to those without diabetes
- the response to diet differs depending on the cause of kidney disease
This means there is no single universal solution.
Each patient has a different metabolic profile and requires a personalized approach.
What does all this mean for you as a patient?
Phosphorus control does not depend only on:
- phosphorus-binding pills
- dialysis sessions
But also on:
- what you choose to eat
- how consistently you move
- whether or not you have diabetes
The correct approach is an integrated one: adapted diet, regular movement, careful monitoring, and close collaboration with your treating physician.
The hemodialyzed patient should not live permanently with restrictions and frustration.
With correct information and medical support, balance is possible.
Phosphorus can be kept under control — but not through a single measure, but through a personalized strategy.
