Management of Micronutrients Loss During Dialysis

In general both the deficiency and excess of any element in the body can affect health. When the kidney function declines or completely absent the balance of various substance in the body gets disrupted leading to serious complications. ESRD is usually associated with a state of oxidative stress, chronic inflammation, antioxidant depletion and imbalance of some trace elements
What affects the trace elements status in CKD?
In CKD due to dietary restrictions apart from major nutrients (proteins, fats, carbohydrates) deficiency. They may also suffer from deficiencies of major micro nutrients particularly trace elements and nutrients

-Anorexia(poor appetite), altered taste, nausea
-Dialysis loss (water soluble vitamins, type filter > loss, high influx and PC)
-Uremic conditions
-Altered distribution and intestinal uptake
-Medications (interfere with absorption)
-Proteinuria (protein – bound trace elements loss)

Commonly occurring vitamin deficiencies in undergoing dialysis are vitamin C (Ascorbic acid), Folate, B vitamins and Calcitriol
Your doctor will prescribe the right dosage of supplements that you should take for the respective vitamin deficiency
Coming to trace elements deficiency more commonly we observe zinc and selenium
Zinc deficiency causes anorexia, alteration of taste and smell, delayed wound healing and anemia. Dietary sources of zinc include legumes, cereals and diary products.

Selenium deficiency leads to hypertension, cardiomyopathy and increase susceptibility to oxidant stress in hemodialysis. Dietary sources – nuts(restricted/moderate consumption), cereals, mushroom, fish and eggs.

Oral trace element supplements are readily available and oral zinc and selenium preparation have been shown to increase blood levels of these elements in people undergoing dialysis. Your doctor will prescribe the right dosage of supplements that you should take for the respective deficiency
Along with these there comes antioxidant deficiency because of less intake of antioxidant vitamins like vitamin E, vitamin C and carotenoids.
When considering vitamin supplementation for individuals with CKD, we should aware of certain factors. General multi-vitamins are not recommended for those with CKD in later stages.

As the kidney function declines, the body requirements for certain vitamins may change. Each micronutrients and vitamins has specific food sources where they are found. A balanced diet with a variety of fruits, vegetables (dialysis friendly), whole grains and proteins typically provides the necessary vitamins for overall health and well -being.

Consult your dietician for the right amount of foods required for you to get maximum nutrients.
