Symptoms of acute renal failure in the elderly

The symptoms of acute renal failure in the elderly are a common disease among the elderly, with the highest incidence rate among people over 60 years old. Acute renal failure is a relatively serious physical disease that often brings great physical pain to patients. Acute renal failure has multiple sites of onset. In addition to the kidneys, various organs and parts of the body will often experience short-term, intermittent pain.

In addition, acute renal failure can also cause severe hypertension: severe hypertension can cause renal arteriosclerosis, reduced renal blood flow, and renal function damage. Disease of the renal arteries themselves can also be a cause of loss of kidney function. Let’s take a look at some of the causes of this disease.

Causes of acute renal failure:

Acute renal failure is also called acute tubular necrosis. The disease often occurs after a large amount of tissue damage, such as crush injury, large blood vessel surgery, acute necrotizing pancreatitis, severe fractures, Gram-negative bacterial sepsis and certain infectious diseases. Acute renal failure can also be caused by excessive blood loss, dehydration and heart failure-induced hypotension, renal insufficiency, acute glomerulonephritis, fulminant pyelonephritis, acute rejection of transplanted kidneys and substances that are particularly toxic to the kidneys, such as mercury, bismuth, phosphorus, carbon tetrachloride and certain toxins and antibiotics. If acute renal failure is treated properly, renal function can be restored. It takes about 2 to 4 weeks from the onset of acute renal failure to the basic recovery of renal function. During this stage, most patients need hemodialysis to maintain life.

Causes of chronic renal failure:

Glomerulonephritis: Immune complexes cause various pathophysiological changes leading to glomerulonephritis and ultimately renal failure. Renal failure can occur within a few months or may last for several years until serum urea and creatinine rise and renal function drops to half of that of a normal person, at which point symptoms appear. Sometimes glomerulonephritis is not diagnosed until years after onset, when the terrible uremic symptoms appear.

Interstitial nephritis: Interstitial nephritis is the second leading cause of chronic renal failure. Tubular atrophy, fibrosis, and scarring lead to reduced glomerular blood supply and decreased renal function. Nephropathy caused by analgesics, gouty nephropathy, and nephropathy caused by antibiotics and other nephrotoxic drugs are all interstitial nephritis.

Some diabetic patients with long-term diabetic nephropathy may develop renal complications, especially those with juvenile or type 1 diabetes who may develop proteinuria, which is often the first indication of kidney involvement. About half of diabetic patients who develop kidney disease will develop renal failure after 5 years, and other complications of diabetes, such as reticuloendothelial system, vascular system, and nervous system complications may also occur at the same time.

Polycystic kidney disease: Polycystic kidney disease is a congenital disease that can occur in several patients in the same family. Pathological examination revealed developmentally defective water-filled cysts. Compression of normal renal tissue. The disease can remain hidden for a long time and is not diagnosed as polycystic kidney disease until the kidneys become enlarged and renal dysfunction becomes obvious after the age of 40 to 50.

Acute renal failure is a relatively serious physical illness that is difficult to prevent. It is best to detect it early and treat it early, and choose a hospital with good treatment conditions for treatment. Of course, patients with this disease do not need to worry too much. Actively cooperating with the doctor's treatment will have a certain effect on the recovery of the disease.
