How is kidney failure caused

Dec 28, 2016
Renal failure may be caused by a variety of reasons, to sum up, there are three main causes of renal failure: toxic substances, immune response to drugs, as well as acute glomerulonephritis infection or disease, can cause renal failure; severe burns when the sudden drop in blood pressure, severe bleeding (e.g. by crushing injury) or a heart attack, can lead to blood disorders, thus damage the kidney; a final cause of urinary tract obstruction is the place, the urine flow suddenly and completely blocked.
Renal failure can be pided into acute and chronic, acute renal failure disease progress rapidly, usually due to insufficient supply of renal blood flow (such as trauma or burn), renal obstruction caused by dysfunction due to certain factors or by poison damage caused by acute renal failure. Chronic renal failure (CRF) is the final outcome of various progressive nephropathy, so many causes of renal failure occur, the most common are the following:
1, chronic glomerulonephritis: such as IGA nephropathy, mesangial proliferative glomerulonephritis; focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis.
2, metabolic abnormalities caused by kidney damage, such as diabetic nephropathy, gouty nephropathy and amyloidosis nephropathy.
3, vascular renal lesions, such as hypertension, renovascular hypertension, renal arteriolar sclerosis, etc..
4, hereditary nephropathy, such as polycystic kidney disease, Alport syndrome.
5, infectious kidney disease, such as chronic pyelonephritis and renal tuberculosis.
6, systemic systemic diseases, such as lupus nephritis, vasculitis renal damage, multiple myeloma.
7, toxic nephropathy, such as analgesic nephropathy, heavy metal poisoning nephropathy.
8, obstructive nephropathy, such as ureteral obstruction; reflux nephropathy, urinary calculi, etc..
Symptoms of renal failure
Renal failure can be pided into acute and chronic, acute renal failure disease progress rapidly, usually due to insufficient supply of renal blood flow (such as trauma or burn), renal obstruction caused by dysfunction due to certain factors or by poison damage caused by acute renal failure. Chronic renal failure is the main cause of long-term renal disease, with time and disease, kidney function gradually decreased, resulting in the occurrence of renal failure.
On the performance of renal failure, patients due to different conditions, the disease will be different, in general, the digestive system anorexia, nausea, vomiting, urine odor. Nervous system fatigue, headache, dizziness, drowsiness, irritability, apathy, severe convulsions, coma. The cardiovascular system had left ventricular hypertrophy, hypertension, retinal hemorrhage, myocarditis, pericarditis, visual disorder; hematopoietic system anemia, bleeding tendency. Deep breathing respiratory metabolic acidosis, there may be a sign of pleurisy. Pruritus with pigmentation, water electrolyte imbalance. When kidney damage to a certain extent, the patient's physical changes and symptoms will be obvious. Kidney failure patients will be different.
Renal failure is very harmful to patients, and seriously affect the patient's daily life and work. Kidney failure on patients harm, together to understand.
The risk of renal failure in patients
1, psychological harm
Because the risk of renal failure is relatively large, coupled with the long-term treatment effect is not very good, it is easy to give the patient's psychological burden, long-term negative will only aggravate the patient's condition.
2, complications
Almost all parts of the body will be affected by renal failure, including the patient's heart, liver, spleen, lungs, kidneys and bones and skin are affected.
3, physical harm
What are the main hazards of renal failure, digestive system will harm patients with renal failure, there will be loss of appetite, abdominal discomfort, nausea, vomiting and other symptoms of some columns, but also have a certain effect on the nervous system of the patients, the patient will appear dizziness, fatigue, dizziness, memory loss and the symptoms of numbness of limbs skin pruritus and coma; patients also have hypertension, heart disease and heart failure.
Therefore, in daily life, once found the condition, to a timely manner to the regular hospital for diagnosis and treatment, according to their condition choose scientific treatment, so as not to delay the disease.
