Frequently Asked Questions

What does your kidney do?

Kidneys are very important organs. Their job is to filter out all the toxins, drugs and waste products into your urine. They are also regulators of electrolytes, fluid, blood pressure.

What are signs and symptoms of acute kidney diseases?

Acute kidney disease occurs when your kidney suddenly does not do its job of filtering out waste products from your blood, causing these toxins to unsafely accumulate within your body. Possible symptoms are fluid retention, swelling, shortness of breath, fatigue and for a few people, low appetite.

What is chronic kidney disease (CDK)?

CKD is when your kidney functions decrease over a long period of time and are unlikely to improve. Diabetes and high blood pressure tend to lead towards CKD. Routine bloodwork, showing increasing high creatinine level (lower kidney functions), blood or protein in your urine, and high blood pressure are some of the indicators pointing towards CKD. Some ways to help prevent CKD are controlling your blood pressure and living a healthy lifestyle through low salt, low sugar and low fat diet and exercising.

What if I have kidney stones?

Depending on the size of your kidney stones, you may feel pain in your back, abdomen or while urinating. You may also have blood in your urine. Increasing intake of water, along with taking pain medication, may allow the kidney stones to pass through. However, if the kidney stones are too large, other treatment methods such as shock wave lithotripsy and surgery are used to remove the kidney stones. For people who tend to produce more stones, medication may reduce kidney stones formation.

Why is it important to treat hypertension?

Hypertension, if left untreated may lead to kidney failure. It may also lead to heart failure, coronary arterial diseases and increase your chance of stroke.

What is dialysis and what type of dialysis are there?

End Stage Kidney Failure (ESRD) is when the kidney has reached a stage where its function is too low and needs intervention. Dialysis is the treatment for End Stage Kidney Failure. ESRD. Dialysis replaces the kidney in filtering toxins and electrolytes out of the blood. One type of dialysis is hemodialysis, in which blood is removed through needles and then is filtered through a machine and is returned to your body. Peritoneal dialysis, another type of dialysis, uses a machine to place fluid in the abdomen for several hours and then remove the absorbed toxins/electrolytes and water from the blood.

Kidney transplantation is the ultimate goal in treating ESRD, however not all patients can undergo this type of treatment.
