Fish Oil, kidney failureFish oil is something good to Kidney Failure patients, it can be obtained from eating fish or by taking supplements. What kind of benefits can fish oil being to Kidney Failure patients?

When the condition develops Kidney Failure, some complications such as high blood pressure, heart disease, osteoporosis, atherosclerosis and so on. Fish oil plays a very important role in treating or relieving these complications of Kidney Failure.

Taking fish oil alone or in combination with calcium and evening primrose oil seems to slow bone loss rate and increase bone density at the thigh bone and spine in elderly people with osteoporosis.


Fish oil seems to slow or slightly reverse the progress of atherosclerosis in the arteries serving the heart (coronary arteries), but not in the arteries that bring blood up the neck to the head.

Kidney problems

Long-term use (two years) of fish oil 4-8 grams daily can slow the loss of kidney function in high-risk patients with a kidney disease called IgA nephropathy. Fish oil also seems to reduce the amount of protein in the urine of people who have Kidney Failure as a result of diabetes.

High blood pressure and kidney problems after heart transplant

Taking fish oil seems to preserve kidney function and reduce the long-term continuous rise in blood pressure after heart transplantation.
