Kidney Failure

Kidney failure is one of the renal disorders in which kidneys lose their ability to filter toxins, salts, excess fluid, electrolytes and waste products from the blood. In general renal failure develops quickly. Renal Impairment can develop in two forms as acute kidney failure which is besides named acute kidney injury or chronic kidney failure which is also called chronic renal failure. Acute renal failure is most familiar in groups who are already hospitalized patients because of having a serious illness and are in intensive care unit which is almost known as hospital-acquired acute kidney failure. Acute renal failure can be deadly and necessitates support for the intensive care or treatment. However, acute renal failure may be reversible kidney function disorder. In other words, if the patient is otherwise in good health, he/she can get better normal kidney function. For a short period the patient with acute renal failure may need dialysis with dialysis machine and then may recover. However, chronic kidney failure may develop little by little and insidiously. Chronic renal failure can be the long term outcome of irreversible acute disease or division of progression of an unidentified disease. What are the symptoms of renal failure? 1- Reduced urinating even though occasionally urine production remains usual. 2- Fluid or liquid retention which causes your ankles, feet or legs to swell. 3- Swimming of the head, feeling of dizziness and drowsiness. 4- Labored breathing or shortness of breath. 5- Signs of physical and mental fatigue and tiredness. 5- Mental confusion 6- Sensation of nausea and vomiting. 7- Complaint of chest pain and feeling of tightness in the chest. 8- Seizures and coma according to severity of the kidney disease. Sometimes renal insufficiency has any signs or symptoms and is discovered throughout laboratory tests done for another health investigation.

What are the causes of either acute or chronic renal failure? 1- When something causes your kidneys to damage and unable to filter electrolytes from your blood as urinary system such as blood clots in the vascular system as in veins and arteries or in and around the kidneys, cholesterol deposits, glomerulonephritis, hemolytic uremic syndrome, lupus and serious viral infections. 2- When blood flow velocity decreases to your kidneys due to a disease such as loss of blood, severe infections, cirrhosis of the liver, heart attack, serious dehydration, anaphylaxis, heart diseases and burn injuries. 3- When the urine fails to leave your urinary system in which electrolytes and waste products filtered by your kidneys remain in your body known as urinary obstructions such as kidney stones, enlarged prostate, prostate cancer, bladder cancer, cervical cancer and colon cancer. Then, what are the risk factors of kidney failure? What are the conditions that can cause to increase the risk of renal failure? 1- Being hospitalized with a diagnosis of serious illness or being put into intensive care because of long-term long term treatment. 2- Advanced age. 3- Blood vessel blockages in the arms and legs known as peripheral arterial disease. 4- Hypertension. 5- Kidney diseases. 6- Liver diseases. 7- Heart failure. 8- Diabetes. If you have kidney failure, you probably may follow a special diet with lowered potassium foods and lowered sodium products by the recommendation of a dietitian who can examine your diet and propose alternatives to formulate your diet easier on your kidneys. Patients with renal failure must care for eating foods low-potassium level such as apple, cabbage, carrot, green bean, grape and strawberry. Besides, they must avoid nutrients with added salt such as salty snack foods, fast foods, canned foods and frozen foods. Patients with an acute renal failure may no longer necessitate following a special diet after kidneys’ recovery.
