Types of Renal Failure in Seniors

Types of Renal Failure in Seniors


  1. Acute renal failure

In this case, changes in the balance of water, electrolytes and other substances develop rapidly. This condition develops in old age much more often than at a young age. It can be caused by any of the serious diseases such as pneumonia, intestinal infection, intestinal obstruction, complicated peptic ulcer, and many others. In the first place, of course, are those diseases that cause dehydration: poisoning, surgical diseases, accompanied by vomiting, diarrhea, or blood loss.

Why does it happen?

In old age, the renal circulation is much worse. And when the body redistributes blood due to a serious illness in order to get more of it to the heart and brain, the kidneys suffer greatly and at a rapid rate.

In elderly people, acute renal failure often develops in a post-adrenal manner. Basically, it is caused by stones, which are easier to fall in conditions where the pH level of urine are affected as one grows older.

Another cause of post-renal failure may be tumors, which also develop more often in the elderly. This is due to decreased immunity in old age and the removal of the “wrong” cells. This may lead to the formation of tumors.

  1. Chronic renal failure

atherosclerosis of the renal vessels;


chronic glomerulonephritis;

kidney amyloidosis;

kidney damage drugs;

chronic pyelonephritis;

tumors located near or in the ureter;

taking drugs that are toxic to the kidneys;

In these cases, the vessels carrying blood to the kidneys become so damaged that they are unable to pass enough nutrients to the kidneys.
