How Hemodialysis Affects Long-Term Health

How Hemodialysis Affects Long-Term Health

Hemodialysis, a type of dialysis treatment, plays a crucial role in sustaining the lives of those suffering from severe kidney disease or kidney failure. The process involves circulating the patient’s blood through a machine known as a dialyser, which cleanses the patient of toxins before being returned to the body. Doctors often perform hemodialysis in a dialysis centre, but patients can also carry out the procedure at home, known as home hemodialysis. This option depends on patients’ conditions and doctors’ recommendations.

Over time, however, the physical toll of hemodialysis treatment on the body can lead to various long-term health challenges. This is not exclusive to hemodialysis but can also occur in peritoneal dialysis, which is another type of dialysis. These conditions can range from cardiovascular issues to degeneration of bone health. That said, patients and healthcare providers should be aware of these potential risks. Taking appropriate steps to mitigate risks is crucial for preserving the patient’s health and overall quality of life.

Short-term Effects of Hemodialysis

The process of hemodialysis involves connecting the patient to a dialysis machine via vascular access, usually a catheter. Vascular access is essential for hemodialysis. It is the site where blood is removed and returned during treatment. A dialysis session typically runs three times a week and lasts for about four hours. This is where waste products and extra fluid are removed, as the diminished kidney function can no longer filter it out. Even in these initial stages, it is normal for patients to experience some physical discomfort as their body adjusts to the process.

Despite the potentially life-saving benefits, the short-term effects of this treatment are considerably challenging. Patients immediately experience changes such as fatigue from long dialysis sessions and muscle cramps from rapid fluid removal. They may also face low blood pressure from such sessions. Furthermore, some patients experience frequent infections due to the catheter’s consistent use, which provides a likely entry point for bacteria.  Peritoneal dialysis, an alternative to hemodialysis, has comparable short-term effects. These effects include infection risk at the catheter site and changes from continuous dialysis fluid in the abdomen.

Long-term Effects of Dialysis Treatment on Health

People commonly seek hemodialysis as a treatment option for kidney diseases such as chronic kidney disease. Many patients begin with a hemodialysis session at a dialysis centre under the watchful eye of a trained technician. However, the journey doesn’t end with mastering the type of hemodialysis or feeling comfortable in the dialysis centre’s surroundings.

Over time, it becomes evident that navigating through the dialysis process has consequences on one’s overall health. One of the dominant effects is alterations in cardiovascular and bone health, which present an attribute of intrigue for medical practitioners and research scholars alike. Long-term use of the hemodialysis machine, although a lifeline for many, carries significant implications for the patient’s well-being that necessitate continual management and care.

Impact on cardiovascular health

In patients who receive hemodialysis over a long duration, there may be a substantial rise in certain health risks. During the hemodialysis dose, a machine circulates the patient’s blood, cleaning it before returning it to the body through a fistula or graft. Over time, these patients may witness an increased rate of hospitalisations due to cardiovascular events.

While standard hemodialysis at a dialysis facility usually occurs three times a week, more frequent hemodialysis at home, such as nocturnal or daily sessions, may help reduce some cardiovascular risks. It’s important to underscore that hemodialysis removes not only toxins but also some necessary nutrients from the body, which could potentially strain the heart. Moreover, the interaction of the dialysis patient’s blood with the dialysis machine may result in inflammation, another factor contributing to cardiovascular risk. These individuals must stay vigilant for any signs of infection to ensure prompt treatment, minimising the detrimental impact on the cardiovascular system.

Effects on bone health

Frequent hemodialysis treatments may predispose patients, especially those with end-stage kidney disease, to a myriad of bone-related complications. Disturbances in mineral and bone metabolism are common among hemodialysis patients. Disruptions in the body’s regulatory systems primarily drive these issues. The optimal hemodialysis frequency is crucial for addressing kidney issues. It must strike a balance between maintaining health and preventing additional complications. Consistent exposure to the hemodialysis process can potentially exacerbate bone conditions, emphasising the importance of carefully calibrated, patient-specific hemodialysis plans. Such plans aim to provide effective kidney disease management while curbing unwanted side effects.

Start Hemodialysis Treatment for Your Kidney Health

The hemodialysis process, often simply called dialysis, can have multiple impacts on patients, both in the short and long term. As a treatment for severe kidney issues, this process necessitates a dialysis catheter, which presents potential complications from infection to blood clots. Immediately after the start of treatment, some individuals may experience fatigue, low blood pressure, or skin irritation around the catheter site. Notably, these short-term aftermaths are generally manageable and tend to alleviate as the body adjusts or as treatments adapt to patient needs.

As for long-term effects, a thorough understanding is vital for maintaining patient health. Evidence suggests clear associations between ongoing hemodialysis therapy and the likelihood of cardiovascular ailments. Patients with no prior cardiac history have reported heart disease, arrhythmias, and other cardiovascular problems. Since dialysis became more widely employed, researchers have documented changes in bone density and an increased risk of fractures. These findings highlight the significant concern of the effects on bone health.

These complexities underscore the sheer importance of careful management and diligent dialysis practice. Both intermittent hemodialysis and chronic modalities require careful attention to hygiene. This is especially important for dialysis equipment to prevent infections and other complications. Ongoing research, such as the cooperative dialysis study, offers remarkable insights into optimising this treatment. This helps countless patients undergoing dialysis better manage their condition.
