Muscle weakness is commonly seen in patients on dialysis. It might be due to the following causes:
* Patients on dialysis are less active than healthy people, which is very likely to cause muscle atrophy.
* Renal failure can cause poor nutrition and many patients on dialysis are malnourished. Therefore, the patients on dialysis are recommended to work with a dietician to ensure that their diet possesses enough nutrients to maintain optimal health.
* Renal failure usually disorder the balance of chemicals in body. Raised chemical level may damage some of the body’s lipids and proteins, which may cause uremic myopathy. Dialysis can help balance the minerals in body and reduce the risk of the muscle weakness.
* Dialysis patients often have abnormalities of their bones and mineral metabolism, which can lead to hyperparathyroidism and vitamin D deficiency and loss of calcium in the bones. These conditions commonly cause muscle weakness.
* Anemia is commonly seen in renal failure and people on dialysis. It may cause fatigue and muscle weakness. Usually, the condition can be relieved by injection of EPO.
* Muscle weakness may be a sign of heart disease which is commonly seen in dialysis patients. Usually, the patients can keep their heart function more effectively by limiting fluid intake between dialysis treatments.
