Chronic obstructive pulmonary disease (COPD) refers to a group of respiratory conditions that cause limited airflow in the lungs and difficulty breathing. If a person with COPD is also experiencing kidney disease, they may require kidney dialysis.
Researchers do not know whether
In this article, we provide an overview of COPD and kidney failure and discuss how these two conditions may be related. We also explain how kidney dialysis works and look at the possible outlook for people with COPD and kidney failure.
COPD is a
Typical COPD symptoms include a cough and shortness of breath. In severe cases, however, COPD can cause respiratory failure.
Chronic kidney failure, also known as
- removing waste products from various bodily processes
- regulating the body’s balance of fluids and electrolytes, such as calcium and potassium
- promoting good bone health
- regulating blood pressure and red blood cell production
Chronic kidney failure can occur for some time without apparent effects on the body. However, it can then start to have
Research indicates a strong association between COPD and chronic kidney failure. Study findings suggest that people with COPD are
Chronic inflammation seems to be a risk factor
Kidney failure means that the kidneys are not working well enough to perform their vital functions. Damage to the kidneys may happen over a long period, leading to kidney failure. However, in some cases, an injury can cause kidney failure to occur suddenly.
A person typically requires kidney dialysis when the kidneys have lost 85–90% of their function.
- encephalopathy, which refers to diseases affecting the brain
- signs of toxins building up in the blood, which include vomiting and poor appetite
- electrolyte imbalances, such as hyperkalemia
- edema, which is swelling due to excess fluids commonly in the legs, feet, arms, or hands
- acid-base imbalances
Kidney dialysis is a treatment that helps the kidneys filter blood to remove waste products, such toxins and excess water. There are two main types of kidney dialysis: hemodialysis and peritoneal dialysis.
Peritoneal dialysis is
The peritoneum contains a high concentration of blood vessels, making it useful for filtering. A doctor makes a small incision in the abdomen and inserts a catheter. A machine can then pump blood through this catheter for the peritoneum to filter.
Some research suggests that people with chronic kidney disease may have a worse outlook if they also have COPD. For example, a
Another study suggests that people with COPD may have a worse outlook if they also have chronic kidney disease. This
However, it is important to keep in mind that everyone is different. Many factors unique to each person can alter the ways in which COPD and kidney disease progress and respond to treatment.
More research is necessary to determine whether COPD can cause chronic kidney disease. Chronic inflammation is a known factor that COPD and chronic kidney disease share.
Although having COPD and kidney failure at the same time can worsen a person’s outlook, treatment options exist for both conditions. COPD treatments include medications to control the symptoms, supportive oxygen therapy, pulmonary rehabilitation, and exercise. For those with kidney failure, different forms of kidney dialysis are available.
