The kidneys are a pair of vital organs that perform many functions to keep
the blood clean and chemically balanced. Unfortunately, a few things can damage
the kidneys over time. The commonest reason for people to develop Kidney Failure
includes Diabetes or high blood pressure. Other factors include certain
medications, low blood pressure, allergic reactions, kidney inflammation,
etc.
Initially, there is very few symptoms of Kidney Failure. With gradual decline
of renal function, it can be first detected on blood test. As Kidney Failure
progresses, symptoms as below may occur due to gradual loss of kidney
function.
■ Swelling
Healthy kidneys can function to get rid of extra fluid, so you may notice the
buildup of fluid with Kidney Failure. It often happens in the legs at first. The
swelling can also lead to weight gain which can be difficult to eliminate with
medications.
■ Anemia
Anemia is a common problem caused by Kidney Failure. The most common cause is
not having enough of a hormone called erythropoietin (EPO). Healthy kidneys make
EPO which tells the bone morrow to make red blood cells. When the kidneys are
not working well, they can not make enough EPO, and then the bone marrow will
not make enough red blood cells. This lead to anemia. Patients may appear
tiredness, weakness, being short of breath, dizziness, etc.
Besides, patients with Kidney Failure can start to feel weak and confused.
The appetite may decline and patient may begin to lose weight. Sometimes, people
notice a metallic taste in their mouth, while other can feel very nauseous and
start vomiting. Usually, these symptoms don't start until you are nearly to lose
all the kidney function and have to receive renal replacement treatments
(dialysis or a kidney transplant).
