How Are AFib and Kidney Problems Linked?

Educate Yourself About AFib and Kidney Problems

Learn as much as possible about your kidneys. Understand the difference between CKD and kidney failure.

Search the Internet and read information from reliable sources such as WebMD and Mayo Clinic. Write down a list of specific questions about your kidneys and take it with you to your appointment with your doctor to help start a discussion to uncover the answers you seek.

In CKD, there is a permanent damage to your kidneys, but they still work enough to do their job of cleaning wastes and extra fluids from the body, controlling the blood pressure and various chemicals in the body, helping make red blood cells and keeping your bones healthy.

As the kidneys get more damaged, this condition progresses to kidney failure. As the name implies, the kidneys fail and can’t work enough for you to live. Kidney failure is treated with dialysis or kidney transplant.

Take Care of Yourself

The best way to prevent CKD and kidney failure is to take care of your health and avoid the risk factors. There are two conditions that increase the risk of CKD that are even more common than AFib: diabetes and high blood pressure.

If you have been diagnosed with either or both, talk to your doctor and find out what you need to do to have them well controlled.

CKD can be assessed with urine testing and specific blood tests for eGFR (estimated glomerular filtration rate).

Check in With Your Doctor

Regular visits to your doctor are important, as your treatment may be adjusted over time.


Check your blood pressure and blood glucose levels at home, according to what your doctor recommends for you. Keep a logbook for both that you can bring along to your appointments.

If you do not have a GP, you should check if there are kidney screening clinics in your area or call 1.866.300.2900, which is a helpline where you can get information about kidney screenings where you live.

Pay Attention to Your Diet

You should avoid processed foods, and adopt a low fat, low salt diet. Smart choices will help you achieve and maintain a healthy weight as well as keep your cholesterol levels under control.

Follow heart-healthy guidelines that focus on eating lots of fresh and frozen fruits and vegetables. Consume lean cuts of meat and include fish at least twice a week.

If you have kidney disease, there are some dietary modifications you will need to make. Discuss these with a registered dietitian to ensure that what you’re consuming isn’t interfering with your kidney function or your medications.

Avoid smoking and drink coffee and alcohol in moderation.

Take Your Medications as Your Doctor Prescribes

Your medications are a vital part of your treatment plan. You should take them daily according to your doctor’s instructions.

It’s recommended to learn as much as possible about these drugs, so you understand what they are for and how they work. If your doctor prescribes anything new, find out first if they will cause any adverse reactions with the other medications you currently take.

If you have concerns about side effects, visit with your doctor and pharmacist. It’s possible that there is an alternative drug that can replace the one that is causing adverse signs or symptoms.

Don’t cease taking any of your medications unless your doctor gives you clearance to do so. If you have concerns that you are taking too many, or the dosage is too high, have that conversation before making any changes on your own.

Remember that your body often requires some time to adapt to a new medication, so allow several weeks for this to take place before deciding whether it’s working as it should.

Be as Active as You Can

Along with diet, exercise can help your entire body to function better, and relax your mind. Try to incorporate physical activity into your routine every day.

The American Heart Association encourages 30 minutes of regular exercise five days a week.

Engaging in activities like walking, bicycling, jogging, swimming, and using a treadmill or rowing machine can improve cardiovascular endurance. Participating in strength training 2 to 3 days per week for each muscle group will increase muscular strength and stamina.

Both types of exercise can reduce the workload on the heart and reduce strain on the kidneys.

For some people, leisure activities like gardening, yard work, or going for a walk with a friend can help reduce tension and anxiety.

Since AFib and CKD these can cause significant stress in your life, you may want to add other relaxation techniques such as deep breathing and meditation.

At this time, medical researchers continue to search for clues on the genetic links between AFib and kidney problems. Unfortunately, conclusive information is not available yet about how effective treatment of AFib will improve outcomes for individuals with CKD.
