Hemodialysis: What You Need to Know – Symptoms, Procedure, Risks, and Lifestyle Tips

Introduction to Hemodialysis

Hemodialysis is a treatment for people with kidney failure. When kidneys stop working well, waste and extra fluid build up in the body. Because of this, hemodialysis helps remove these wastes and fluids. The procedure uses a machine to clean the blood. Many people visit hemodialysis centers for this care. Hemodialysis can help you feel better and live longer.

Symptoms and Signs That May Lead to Hemodialysis

Some symptoms may show your kidneys are not working well. If you notice these signs, you should talk to your doctor. Early care can help prevent problems. Common symptoms include:

  • Swelling in your legs, ankles, or feet
  • Feeling very tired or weak
  • Shortness of breath
  • Nausea or vomiting
  • Loss of appetite
  • Trouble sleeping
  • Itchy skin

    • Sometimes, these symptoms can be mild at first. However, they may get worse over time.

    Causes and Conditions Requiring Hemodialysis

    Many health problems can damage the kidneys. When kidney damage is severe, hemodialysis may be needed. The most common causes include:

  • Diabetes
  • High blood pressure
  • Chronic kidney disease
  • Severe infections
  • Inherited kidney disorders

    • In some cases, sudden injury or illness can also cause kidney failure. Your doctor will decide if hemodialysis is right for you.

    How Hemodialysis Works: Step-by-Step Process

    Hemodialysis uses a special machine to clean your blood. Here is how the hemodialysis procedure usually works:

  • A nurse places two needles in your arm. One needle takes blood out, and the other returns clean blood.
  • Your blood flows through a tube into the dialysis machine.
  • The machine has a filter called a dialyzer. This filter removes waste and extra fluid from your blood.
  • Clean blood goes back into your body through the second needle.
  • Each session lasts about three to five hours. Most people need hemodialysis three times a week.

    • Some people may have hemodialysis at home. However, most visit a clinic or hospital.

    Common Risks and Side Effects of Hemodialysis

    Like any medical treatment, hemodialysis has some risks. Most side effects are mild, but some can be serious. Common risks and side effects include:

  • Low blood pressure during treatment
  • Muscle cramps
  • Feeling dizzy or weak
  • Infection at the needle site
  • Itching or dry skin
  • Headaches

    • Rarely, more serious problems can happen. For example, heart problems or severe infections may occur. Your care team will watch for these issues and help manage them.
