Normally, the blood will flow through the kidneys and allow them to excrete
wastes and conserve electrolytes (mineral salts). Any condition that
significantly interfere with blood flow to the kidney can lead to the loss of
kidney function, thus eventually resulting in Renal Failure. Nausea and vomiting
are typical symptoms of kidney failure and can greatly affect the quality of
life and the appetite of the patient. How does this occur?
Definition
Nausea refers to the feeling of having an urge to vomit, which is often
called being sick to your stomach.
Vomiting, or throwing up is forcing the contents of the stomach up through
the esophagus and out of the mouth.
The severity of the above two symptoms may vary from patient to patient in
different stages. Generally, this phenomenon is more serious in the morning.
Causes
For people with Renal Failure, most of their kidney function has been
damaged, so the kidneys cannot function adequately, causing accumulation of
wastes and toxins throughout the body. With the severe decline of renal
function, the amount of nitrogen in the blood (in the form of urea) will
gradually build up, resulting in elevated BUN levels. Meanwhile, urease in the
intestinal tract can decompose BUN into ammonia. As the level of BUN increases,
large amounts of ammonia will present, thus stimulating the gastrointestinal
tract and causing nausea and vomiting.
Why will you suffer from more severe discomforts in the morning? For some
Renal Failure patients who suffer from frequent urination at night, there is a
large quantity loss of water in the night, which leads to hemoconcerntration, a
condition with increased concentration of cells and solid in the blood. As a
result, the blood urea nitrogen level will raise in the morning. Series of
reactions will lead to your severe nausea and vomiting in the morning.
