Homeostatic Imbalances a Person on Dialysis Might Face
Homeostasis is extremely important for proper functioning of all the human body systems. When our body is not able to regulate temperature all our body functions will fail to work. Even the enzymes need a specific constant temperature to work at their optimum level. At higher temperatures the enzymes will stop working. Dialysis is the artificial process of getting rid of waste (diffusion) and unwanted water from the blood. This process is naturally done by our kidneys. Some people, however, may have failed or damaged kidneys which cannot carry out the function properly, they may need dialysis. The human body relies on homeostasis to function properly, so the body constantly makes adjustments to keep balanced within its physiological limits. The kidneys in the urinary system are a major workhorse in keeping the body in balance. They regulate the ionic composition of blood, pH of blood, blood volume, blood pressure, blood glucose, production of hormones, and excretion of foreign materials and waste products. If this process fails or there is impairment (renal failure), then a person relies on dialysis to artificially clean the blood, remove excess fluid and electrolytes. The patient will have to go to a facility to have this done on a routine schedule. The dialysis machine uses dialysate solution to maintain diffusion gradients that help with removing waste and add other substances; meanwhile the patient will also be heparinized to prevent clotting during the procedure. Patients with renal disease or renal failure have a lot of electrolyte imbalances and most commonly will have too much calcium, called hyperkalemia. The excess calcium can cause arrhythmias. After dialysis the patient usually will have severe cramping due to the shift in pH and removal of excess fluids (concentration). Patients are at risk for
