- What is hemodialysis and how does it work? Who needs it? How do you prepare for it? In the United States, over 30 million Americans have kidney disease, and sometimes, kidney disease progresses to kidney failure or end-stage renal disease. When this happens, you cannot survive unless you have a kidney transplant or some form of dialysis. So today we're going to talk about hemodialysis.
Your kidneys are the two kidney bean-shaped organs that are located in your lower back, or in your flanks. And the kidneys are responsible for filtering out or cleaning your blood. They get rid of excess waste, excess toxins, and excess fluids. If your kidneys stop functioning, then you develop renal failure or end-stage renal disease.
What is Hemodialysis?
Hemodialysis, or blood dialysis, is the filtering of your blood outside of your body. So, if your kidneys stop working properly, the hemodialysis acts as a substitute kidney. Now it's important to note that hemodialysis does not actually correct your own kidney function. It does not fix or treat your kidneys.

What is The Dialyzer?
The dialyzer is actually the filter. It's the main powerhouse of the hemodialysis system, and it is what actually acts as the substitute kidney. In the dialyzer, you have these hollow fibers that run through it, and these fibers are bathed in something called dialysates, or dialysis fluid.
How Often Are Patients Treated With Hemodialysis?
Most patients who are on hemodialysis are on it between three and six hours, about three days a week, especially if they go to a center.
How Does Hemodialysis Work?
So when you are on dialysis, how does your blood get from your body to the hemodialysis machine and then back to your body? Well, it does so through tubes, and those tubes are connected to your access, and we'll talk about access in just a moment. But as far as the tubing, the tubing is connected to your body.
Types Of Hemodialysis Access
Arteriovenous Fistula or AV Fistula
The AV fistula is the gold standard as far as hemodialysis access is concerned because it gives you the most efficient hemodialysis and it is the least likely to be infected.
Arteriovenous Graft or AV Graft
The AV graft is very similar to the AV fistula in that you still have a surgically connected artery and a vein, usually in the arm, but in the case where if you have veins that are rather thin or arteries that are thin and maybe too weak in order to really give you a properly functioning, substantial AV fistula, then the vascular surgeon may opt to add an artificial material in order to make that shunt a little stronger, or little more durable. And so, an AV graft is another option for dialysis access.
Catheter
If you're in a situation where you need temporary dialysis, or if you have acute kidney injury, then you may have a temporary Vascath placed, and it's usually placed in a vein of the neck, the internal jugular vein, or it can be placed in the groin, or in the femoral vein.
Who Needs Hemodialysis Treatment?
How do you know if you need hemodialysis, and when is it time to prepare? Well, if you follow up with your kidney doctor (nephrologist) regularly, he or she will be watching your labs. They'll be able to see those signs of your kidneys not functioning properly.
Dr. Frita thanks for explaining Hemodialysis so clear. You have explained the kidney function so well.
Hi Dr. Frita, thank you so much for sharing this information with us.
Thanks Dr Frta, for all your teachings. I have someone on hemodialysis and it's not easy.
not only are you so interesting to watch and listen to, you are wonderful.
Dear Dr. Frita,
Thank you so much for helping others and the work you do.
You are very welcome. Thank you for watching and be well.
@@DrFritacan we stop hemo dialisys doc ? And remove AVF ? If the creatinine lower 515 to normal?
Hi Dr Frita. I always learn a lot from your videos. But i have a question : why do patients often die while they're connected to the machine ? Is it due to a sudden malfunction of the machine ?
Thank you Doctor Frita
Very helpful and informative. I had my mom watch it because she is worried about using her fistula because she has had severe bruising.
Thank you!
I learned so much, as you explained the functions of our Kidneys. Thank you Dr. Freda.
That’s Right You Can’t Live Without A Heart Kidney Brain And Liver
Frita
GREAT VIDEO... I ALWAYS WONDERED HOW DOES A PERSON WORK IF YOU ARE HAVNG TO GO 3-4 TIMES A WEEK
Good evening Mam, you are so grace full
Thanks dr.frita
Thanks for info. I am on dialysis.
Thank You for this information.
Please make a video on how to reverse CKD.
Thank you!
You’re welcome! 😊 I will consider this for a future video. Thank you for watching.
Hey doctor Fooda. Wish I was impatient compared to the one I go to now.
Blessings to you 🙏 Dr Frita we love you and the important videos you send our way ❤
Buenos días.
Thanks for sharing this information with us.
My pleasure, I appreciate you for watching!
I have only but one kidney and I am at stage 3A. I also have what is called restricted lung disease. And I also get a lot of spasms in my arms and legs and when that happens I go flying into first base can anything be done
If the cause of health problem is severe for dialysis is severe infection was there a research to read what's inside the memory t- cell's information or if an autoimmune disease is the cause of dialysis was there a research to analyze the misreading and misdirecting of the immune system on the types of antigens or research on how to reverse genetic mutation, or if the cause of dialysis is severe inflammatory reaction can the information inside the mast cells be analyzed? Because knowing those things can direct the treatment or create new treatment approach.
My father has end stage liver failure and his kidneys aren't working properly, he just started dialysis . I was wondering what are his changes ? He isnot on a transplant list for his liver or kidneys and he's had end stage liver failure for several years now.
What are advantages and disadvantages of hemodialysis and peritoneal dialysis
Was there a research about how the stem cell differentiation like for example how bone marrow stem cells or umbilical cord stem cells which differentiate to create cells for heart, brain, muscles, kidneys, liver, lungs etcetera a stem cell differentiation on organs in a controlled manner wherein a defective organ can be the focus of controlled stem cell differentiation for the treatment of that particular organ like for example if the nephrons, or glomerolus, or renal tubules were affected the stem cells will be focus to repair those organ parts and aside from that what if a new regenerative research will be undertaken focusing on how the body repair itself and push that regenerative capability of the body to the maximum.
Hi🖐😍Thank you for this video.
You are so welcome!
Dr. I'm getting diabetes when my husband passed away. They said it was the shock. Now a few years later I got very sick and in hospital. That Prof. said I do have Hart and kidney failure due to deabetes and its buzzy sutting down my organs. I'm also COPD and have Ostrio Arthritis. He also said in my stage nothing will help I must just go on like this.... 🙈 I do drink about 5liters water per day and drink water tabs but get alot infections in my bludder, but only take home remedies for that. What do you think? I'm from South Africa and no medical aid and 55 years old. I 95 % only in bed and my burning painful feet is killing me. My feet swelling under the feet. They also dead. Walking wuth a walker. Can you please have advice for me?
I hated it so glad and thankful for my transplant
this has been very educational, I think I would just accept my fate and surrender. but that's just me. I understand those who would choose Hemodialysis.
Hi doctor Freedom my name is Ronnie I need your help soon as possible Stage 5 kidney by my kidney doing really good right now I need help from you because doctor forcing me to get on dialysis but I don't have any dialysis symptom to be on it can you help me on that side please please
You need dialsis
You don’t need to have necessarily symptoms to start dialysis, if the bloods show you need to start then you need to start, earlier without symptoms it’s better than later in distress fighting for your life. Hope you did start dialysis back then. 🙏
Thank you so much doctor🙏
Dear doctor, may I ask you one question?🙇
I wonder if hemodialysis is ever stopped due to improvement in health (except for kidney transplants)
Yes, nay patients with AKI (Acute Kidney Failure) do recover in time and no longer require dialysis, it is the ESRD (End Stage Renal Disease) patients that require dialysis for the rest of their lives or until a kidney transplant is performed
I’m in 3rd stage Kidney Disease with a Filt Rate that continues to drop and my last blood test was 38.3. How bad is it? Any advice?
I'll advise you to contact Dr. Odion for herbal treatment because he's the one that helps my wife with his herbs
The best is HDF = Hemodiafiltration methode.
nope
@@shellytanner why no ?
Thank you for covering hemodialysis Dr. Frita. I had a kidney transplant 12 years ago. Prior to that I was on hemodialysis (I had the chest catheter) and then peritoneal dialysis.
Do you work with patients on Home Hemodialysis?
From what I've been able to gather it seems that a kidney transplant only lasts about 20 years?🤔 Is this true or is this mis-information?
@@gloriamaryhaywood2217 definitely far from true Gloria. I’m working on year 13 myself and I know many people who are 30 and 40 years post kidney transplant. One is a good friend of mine. Professional Rollerblader Paul Noworita. He’s currently 32 years post kidney transplant and doing great. I interviewed him on my UA-cam channel and we discuss this actual topic. Hope this helped.✌️
@@Exodus1414KeepStill Yes! Clears it right up! I guess I was thinking about when I watched the "Gary Coleman" documentary? He had his kidney transplant about 20 years in and was needing another one, as he was back on dialysis. But I also seem to recall that he had other health issues going on as well?🤔 Anyways, great to know that you and others are doing really good!!😊
Happy you for sharing your caring medical wisdom. You pretty black woman 👩🏽.
💗
Hi thanks for help
I feel always headaches
Special pot party of my head
If there any advise thanks 😊🙏
Dr, does chilling and fever related to CKD?
What stage is it if someone has 40% kidney function?
Hi I'm a hemodialysis patient
I have to do this every 2nd day, for 4 1/2 hrs. Its hell
It is not
