Acute renal failure happens when the kidneys suddenly lose their ability to remove toxins from the urine. Typically the cause for a sudden kidney failure are acute tubular necrosis (ATN) and autoimmune kidney diseases. Other causes leading to kidney damage are acute pyelonephritis and septicemia. The symptoms indicating acute renal failure are changes in urination, lowered sensation in extremities and metallic taste in the mouth. Typical symptoms include nausea, blood in stools, swelling of feet and ankles, swelling of ankle or leg, fluid retention and fatigue. A person might also notice high blood pressure, nausea and reduced appetite. Change in mental alertness might be noticed.
A nephrologist will need to examine the patient and suggest further course of action. BUN test and blood tests for creatinine and potassium are done. Kidney ultrasound or MRI might be done to look for any stones, tumors or blockage. A person suffering acute kidney failure is hospitalized and the amount of liquid ingested in monitored. The diet has to be tailored to reduce proteins and salt. Diuretics might be prescribed for reducing fluid retention. In some cases, dialysis is done; especially when the potassium levels are abnormally high. The balance of body electrolytes is maintained.
Acute kidney failure is more common with older adults and those suffering kidney or liver disease, heart failure or diabetes. An abdominal surgery might also make you more susceptible to kidney failure. Severe dehydration, blood pressure medications and overuse of NSAIDs are other possible causes for renal failure. This condition can be life threatening if not treated in time. It can lead to chronic kidney failure or damage to the nervous system and the heart. The patient can develop very high blood pressure or loss of blood in the intestines leading to last-stage kidney disease. Treatment for kidney disease include antibiotics and iodine-based medications.
Uremia is regarded as the end stage of Kidney Failure. Uremia is also called the 'second cancer'. Uremia is related to the second point filtering blood. The kidney is impaired and does not filter the waste products that result from the body's metabolism. When this function fails, the waste products and blood urea nitrogen accumulate in the bloodstream. This build-up is Azotaemia. Mild levels of azotaemia may not show symptoms. But continued kidney failure to filter the waste result in symptoms and this condition is called uremia.
Uremic patients show varied signs and symptoms collectively called as uremic syndrome.
Gastrointestinal tract: Loss of appetite, discomfort in the abdomen, nausea, vomiting, diarrhea, severe dehydration, oral ulcer, Glossitis (inflammation of the tongue) and urine taste in breath.
Nerves related: Headache, dizziness, lethargy, drowsiness, weakness, fatigue. In advanced stage symptoms such as irritability, muscle trembling, seizures and convulsions may be experienced.
Cardiovascular system: Hypertension and arrhythmia and in the advanced stage heart failure can happen.
Blood forming or hematopoietic system: Serious anemia and in the advanced stage bleeding can happen.
Respiratory system: Shortness of breath, difficulty breathing, chronic cough, respiratory disorders such as pleural effusion (fluid accumulation in the lungs), pneumonia, uremic bronchitis, pleurisy.
To decide on the course of treatment the cause of Uremia is of great significance. As Uremia can be life-threatening, quick and proper treatment may reverse the illness condition. The chief cause is of course, kidney failure or damage to kidneys.
Diseases that affect kidney function:
How is Uremia diagnosed?
Most renal disease including Uremia do not cause symptoms in the early stages. Uremia is likely to be noticed incidentally from blood or urine tests done for other health issues. Urinalysis is done to detect protein and blood in urine. Blood clotting test, kidney biopsy and stool culture to ascertain presence of a certain type of E.coli bacteria or other bacteria.
How is Uremia treated?
If the diagnosis is confirmed, the patient would be hospitalized for observation and treatment. The cause determines the treatment.
Erectile Dysfunction (ED) or Impotence is a condition where a man is unable to develop and maintain an erection during sex. Conditions that lead to impotence are medications such as anti-depressants, kidney failure, diabetes, anxiety, depression and aging. Other causes for ED - Erectile dysfunction include high cholesterol, hypertension and obesity. Low levels of testosterone, metabolic syndrome and atherosclerosis could also lead to impotence.
Lifestyle changes that can help treat erectile dysfunction are reducing stress, quitting smoking and exercising regularly. Oral medications for impotence are Sildenafil and Tadalafil. Viagra is one such popular medication that is used to increase blood flow and relax the muscles in the penis.Tags: #Renal Failure #Uremia #Erectile Dysfunction
