Dialysis is a medical procedure used to perform the functions of the kidneys in individuals whose kidneys are no longer able to adequately filter waste products and excess fluids from the blood. The process is essential for people experiencing kidney failure or end-stage renal disease (ESRD). There are two main types of dialysis: hemodialysis (Hemo) and peritoneal dialysis (PD).
​
Patients typically undergo dialysis when their kidneys are no longer able to effectively perform their crucial functions, leading to a condition known as end-stage renal disease (ESRD) or advanced chronic kidney disease (CKD). The decision to initiate dialysis is based on several factors, including the decline in kidney function, the presence of symptoms such as fluid retention, electrolyte imbalances, and the accumulation of waste products in the blood. Nephrologists assess the patient's overall health, considering factors like blood test results, blood pressure, and the impact of kidney dysfunction on daily life. Once kidney function reaches a critical point where it can no longer maintain the body's internal balance, dialysis becomes a necessary intervention to remove waste products and excess fluids, providing life-sustaining support for individuals with compromised kidney function.

1. **Hemodialysis (Hemo):** This method involves using an external dialysis machine to filter the blood. During Hemo, the patient's blood is circulated through a dialyzer, a device that acts as an artificial kidney. The dialyzer removes waste products and excess fluids from the blood before returning the cleansed blood to the patient's circulation. Hemo is typically performed in a clinical setting, such as a dialysis center, and requires the creation of vascular access, often through an arteriovenous fistula or graft.
​
2. **Peritoneal Dialysis (PD):** In PD, the patient's peritoneum, a membrane lining the abdominal cavity, serves as the filter. A cleansing solution, called dialysate, is introduced into the abdominal cavity through a catheter. Waste products and excess fluids from the blood pass through the peritoneal membrane into the dialysate. After a specified dwell time, the used dialysate is drained, and fresh dialysate is introduced for the next cycle. PD offers the advantage of being performed at home, providing greater flexibility for individuals managing their kidney health.
Dialysis is a critical and life-sustaining treatment for those with compromised kidney function, helping to maintain a balance of essential substances in the body and prevent the buildup of harmful waste products. The choice between Hemo and PD depends on various factors, including the patient's health, lifestyle, and preferences, and is typically made in consultation with a nephrologist.

Dialysis Methodology
Choosing the Right Dialysis
Choosing the right dialysis treatment involves a collaborative decision-making process between you and your healthcare team. Factors to consider include your lifestyle, preferences, overall health, and the specific requirements of each dialysis modality. Hemodialysis (Hemo) is typically conducted in a clinical setting, requiring vascular access, and involves scheduled sessions several times a week. Peritoneal Dialysis (PD), on the other hand, offers more flexibility as it can be performed at home, allowing for greater independence. Discussing these options with your nephrologist will help determine which approach aligns better with your daily life and personal preferences. Additionally, understanding the benefits and potential challenges of each modality, as well as considering factors like travel, work commitments, and family support, will contribute to making an informed decision tailored to your unique circumstances. Open communication with your healthcare team ensures that your chosen dialysis treatment not only addresses your medical needs but also enhances your overall quality of life during the treatment journey.
