Hemodialysis is commonly performed three times a week for patients with kidney failure or those who require dialysis due to chronic kidney disease. This frequency is designed to efficiently remove toxins and excess fluid that accumulate in the body between sessions. Each session typically lasts about three to five hours, and this regimen helps to maintain proper electrolyte balance and fluid homeostasis in patients who do not have functioning kidneys.

Some patients may have more frequent sessions based on their specific health needs, but the standard practice for patients on hemodialysis is three times a week, as it strikes a balance between effective waste removal and patient quality of life. Other suggested frequencies, such as once or twice a week, do not adequately support the needs of most patients with significant kidney impairment. Daily dialysis is an option for a small subset of patients who may benefit from it, but it is not the norm for the general hemodialysis population.
