What Is Dialysis? Hemodialysis vs Peritoneal Dialysis

It is a procedure that cleans the blood that the kidneys normally filter. There are two types of dialysis that are used: hemodialysis and peritoneal dialysis. The difference is where the cleaning process takes place. In hemodialysis, it is conducted by a machine outside of your body, whereas in peritoneal dialysis it occurs inside of your belly using its own natural membrane for the process of purification.

Each day, your kidneys work tirelessly to filter out waste products and control the balance of fluid and minerals in your body without any recognition from you. If kidney function becomes so severely reduced that kidney failure (or End-Stage Renal Disease, ESRD) develops, dialysis takes over to help you continue living your life.

What is hemodialysis?

Hemodialysis is the procedure where blood is cleaned. It is performed by a special device called an artificial kidney that consists of membranes separating blood from a special solution. The blood is drawn out of the patient’s body, enters the artificial kidney, where waste products are removed from it. Then the cleansed blood is returned to the patient.

  • It is typically performed in the clinic and takes about 3 times per week for 3-5 hours.
  • Technicians do all the technical parts
  • Great for those who like to feel taken care of and have some magazines to read in the waiting room.

What Is Peritoneal Dialysis?

The dialyser here is you. You get a special catheter which is inserted into your belly. The peritoneum, the thin lining inside your belly, absorbs the waste from the blood vessels. Then you drain the used fluid and start again.

  • Can be performed at home
  • More comfortable daily schedule, no excessive strain on the body
  • Needs a clean setup and ability to wash hands like a surgeon

What Does Research Say?

None of the options is perfect for everybody. According to Vonesh's review in Kidney International (2006), the survival of the patients is similar at the beginning. However, there are some differences in the outcome depending on age and health condition. The results of the trial FHN in the New England Journal of Medicine (2010) indicated that six sessions of hemodialysis per week improved blood pressure and heart function compared to three sessions a week. The classic CANUSA study (1996) found a correlation between the adequacy of peritoneal dialysis and better outcomes. In other words, the best choice depends on the patient.

How to Pick One

Ask yourself: Do I need a routine in the clinic or freedom at home? Can I manage the sterile setup? Do I have any help nearby? A nephrologist will consider my health, previous surgeries, and lifestyle. It will be impossible to guess without talking to the doctor.

Ways of Maintaining Healthy Kidneys

Dialysis is not the whole answer, and there are plenty of home remedies for healthy kidneys that are quite boring:

  • Ensure your blood pressure and blood sugar are normal
  • Try to limit your use of salt and processed food
  • Drink a lot of fluid, unless there is any limit set by your doctor
  • Avoid pain medication such as ibuprofen unless approved

Although googling home remedies to help your kidneys is good, always bear in mind that a glass of coriander water does not substitute for treatment. However, a good lifestyle makes your care plan work better.

Ayurveda As A Complementary Medicine

Additionally, many patients investigate kidney disease Ayurvedic treatment in parallel with routine care, aiming to achieve overall health and to improve nutrition. Like in the case of other alternative therapy, it is recommended to consult your nephrologist to discuss this issue and to make sure that your choice does not have any side effects and interfere with the current treatment. Remember, these methods should supplement standard care.

Final Thoughts

With dialysis, people learn to live their lives to the fullest. If you are looking for more than just medical assistance, you can think about visiting Karma Ayurveda for kidney disease treatment, but make sure you tell your doctors about it.

Key Takeaways

  • Dialysis filters your blood when your kidneys can’t
  • Hemodialysis uses a machine, usually at a clinic
  • Peritoneal dialysis uses your belly lining, usually at home
  • Research shows neither is better for everyone
  • Healthy habits and honest chats with your doctor matter most
