Hello,
To the question "How to limit itching symptoms when dialysis?", the doctor would like to answer as follows:
Itching is also a common complication of dialysis. This symptom may be precipitated or aggravated by dialysis. If itching is accompanied by other mild allergic reactions, it may be a mild allergy to the dialysis membrane or components of the dialysis line. However, the most common pruritus symptom is chronic.
Itching in dialysis patients is caused by many causes: hyperphosphatemia, stagnation of medium molecular weight substances, skin diseases (dermatitis), allergies....To determine the cause As a cause of itching, viral (or drug-induced) hepatitis should not be ignored as this may be a potential cause.
Skin rash (also called urticaria) is an outbreak of swelling, redness, or plaque on the skin that appears suddenly, due to the body's reaction to certain allergens, or for unknown reasons. .
