Kidney failure doesn't mean life stops: Here is your clear guide to understanding dialysis

Have you ever heard a doctor talk to someone in your family about kidney trouble? Hearing that your kidneys are failing and you might need dialysis can feel very scary and shocking.

You probably have many questions running through your head right now. What is dialysis, and do you really need to be afraid of it? Can you still live a normal life with this treatment?

Do not worry. Today, we will talk about this in a very simple way so that you can understand it completely.

What Is Dialysis?

Simply put, dialysis is a medical treatment that steps in when your two kidneys stop working well. It does the job that your kidneys are supposed to do for you.

Think of your body as a large factory that is always busy working. This work creates waste products every single day.

Your two kidneys are like the ultimate cleaning system inside this factory. Their main job is to filter extra water, waste products, and poisons out of your blood, turning them into urine to leave your body.

They remove harmful nitrogen waste, like urea, and waste from your muscles, like creatinine. Now imagine what happens if this filter system breaks down and stops working.

All the trash made in the factory builds up, and the whole system becomes messy and unsafe. That is exactly what happens when kidney failure occurs.

Poisons, waste, and extra fluid start to build up in your blood. This condition is very dangerous for your life.

Dialysis does that exact job for you. It cleans your blood using a machine or a special process when your kidneys cannot do it anymore.

Just like you buy bottled pure water when your home water filter breaks, dialysis cleans your blood when your kidneys stop working.

Who Needs Dialysis Treatment?

Not everyone with a kidney problem needs to have dialysis. It is only needed for people in late-stage kidney disease or those with complete kidney failure, known as End-Stage Kidney Disease, or ESKD.

Kidney disease usually has five stages. By the time you reach stage five, your kidneys are working at less than 15 percent of their normal level.

At this point, your body can no longer clear the built-up poisons on its own. That is when you need dialysis or a kidney transplant to stay alive.

Some people use dialysis as a bridge while they wait for a kidney donor. Others rely on it long term.

Common Causes of Kidney Failure

• High Blood Pressure: High blood pressure that is not controlled over time is a main cause of kidney damage.
• Diabetes: High sugar levels in the blood from diabetes damage the tiny blood vessels inside your kidneys.
• Lupus and Other Diseases: These are conditions where your body's defense system attacks your own healthy organs.
• Other Causes: Sometimes, a sudden injury or a severe infection can cause kidneys to fail quickly. Other people develop kidney disease without doctors finding a clear cause.

Starting dialysis is a major decision. However, if someone with kidney failure does not get dialysis, poisons build up in the blood, leading to a condition called uremia, which can cause death within days or weeks. Therefore, this is an essential treatment to save your life.

Two Main Types of Dialysis

When people hear the word dialysis, they usually only think of being hooked up to a big machine to clean the blood. But there are actually two main ways to do dialysis. Let us look at the differences simply.

1. Hemodialysis

2. Peritoneal Dialysis

Your doctor will help you decide between these two methods based on your health condition and your daily lifestyle.

More Details About Hemodialysis

This is the most common form of dialysis used around the world. Here is how it works:

1. Getting Ready: Because a dialysis machine pumps blood quickly, your regular blood vessels cannot handle that high speed. Therefore, a surgeon does a minor surgery to connect an artery and a vein in your arm to create a large, strong blood vessel called a fistula. This access point is used to take blood out and put it back in.

2. The Treatment: When you go to the dialysis center, a nurse puts two needles into your fistula. One needle takes blood out of your body and sends it to the dialysis machine. As the blood passes through a fake filter called a dialyzer inside the machine, waste and extra water are removed. Then, the clean blood flows back into your body through the second needle. This process takes about 3 to 4 hours. During this time, you can sit in a chair, read a book, or watch television.

More Details About Peritoneal Dialysis

This method is quite different. It does not use a large machine. Instead, it uses a natural part of your own body as a filter.

1. Getting Ready: Before starting this treatment, a surgeon places a soft, permanent tube called a catheter into your belly.

2. The Treatment: Through this tube, a special cleaning liquid called dialysate is filled into your belly space. The peritoneum is a membrane lining the inside of your belly that contains many tiny blood vessels. While the liquid sits inside your belly, it acts like a magnet, pulling waste and extra water out of your blood. After a few hours, the fluid filled with waste is drained out through the tube and thrown away. This process is called an exchange.

There are two main ways to do this:

• CAPD (Continuous Ambulatory Peritoneal Dialysis): You change the fluid yourself about 3 to 5 times during the day. Hanging a fluid bag higher than your belly lets gravity pull the liquid inside. This takes about 30 to 40 minutes.
• APD (Automated Peritoneal Dialysis): This is much easier for many people. Before you go to sleep at night, you connect yourself to a small machine. While you sleep, the machine automatically changes the fluid several times through the night.

Life With Dialysis: Should You Be Afraid?

These are some of the biggest questions people have when starting dialysis. Let us look at them one by one.

Does Dialysis Hurt?

• Hemodialysis: You only feel a small pinch when the needle goes into your vein. After that, there is no pain during the treatment.
• Peritoneal Dialysis: There is no pain at all during this process. However, when your belly fills up with fluid, you might feel a bit full or heavy.

What Are the Risks of Dialysis Treatment?

Like any medical treatment, dialysis has some risks.

• During Hemodialysis: There is a risk of infection at the access site where the needles go in. Blood clots can also block the blood vessel. Sometimes, your blood pressure can drop. But do not worry, machines have safety systems built into them. If anything goes wrong, an alarm sounds and the machine stops to protect you from harm.
• During Peritoneal Dialysis: The main risk is an infection of the belly lining, called peritonitis. This can happen if germs enter through the tube. Therefore, you must keep everything very clean. Over time, belly muscles can also weaken, which may lead to a hernia.

Will My Kidneys Get Better Again After Dialysis?

This is a very common question. Dialysis is not a cure for kidney disease. It only does the job of your kidneys temporarily. Kidney failure, or ESKD, is a condition that cannot be reversed. Because of this, you must continue dialysis for the rest of your life unless you get a kidney transplant.

How Long Can Someone Live on Dialysis?

There is no single answer to this question. It varies a lot from person to person. Your age, overall health status, and the disease that caused your kidney failure all affect this. However, many people live happily for many years, and sometimes decades, by following their treatment and listening to doctor advice.

Can You Do Normal Activities With Dialysis?

Absolutely yes. Doing dialysis does not mean your life is over. Many people continue their jobs, take care of family duties, and live a normal life. You can even travel. If you do hemodialysis, you can talk to a dialysis center at your travel destination to plan your treatments there. If you do peritoneal dialysis, it is even easier because you can pack your fluid bags and take them with you.

Watch for These Symptoms: Tell Your Doctor Right Away

If you are receiving dialysis treatment, tell your doctor or your treatment center right away if you notice any of the following signs.
