Kidneys are two bean-shaped organs within our body. On the one hand, they can help filter metabolic products, toxins, extra fluid out of the body. On the other hand, they are responsible for the production of red blood cells and bone health. When kidneys are failed, a range of symptoms will occur, such as, high blood pressure, swelling, proteinuria, etc. Generally, when the GFR level declines to 15ml/min or below, dialysis will be recommended by your doctors.
As an alternative therapy, dialysis is commonly used in kidney failure patients. In addition to excreting wastes out of the body, it can also help relieve some of the symptoms to a certain degree.
To be frank, dialysis is mainly categorized into two types: hemodialysis and peritoneal dialysis.
Hemodialysis uses a dialyzer to clean your blood. Before this treatment, an access to your blood vessels should be made to get your blood into the dialyzer. The access can either be internal or external. In addition, it can be done at home or a kidney disease hospital.
Hemodialysis is usually done three times a week. And each procedure can last for 2 to 4 hours.
Comparatively speaking, peritoneal dialysis is more flexible. It uses the lining of your abdominal area as a filter. Based on the specific condition, your doctor will determine which type of dialysis is appropriate for you.
Simply speaking, the functions of hemodialysis can be concluded into the following three aspects:
1.Remove metabolic products, extra fluid and toxins out of the body.
2.Lower high blood pressure
3.Regulate chemical levels in your body, for instance, sodium, potassium, phosphorus and so on.
Honestly speaking, how long will dialysis take is determined by your own conditions:
-which type of dialysis you choose
-the residual renal function
-your body weight or the content of fluid
-levels of toxins in your body
Both hemodialysis and peritoneal dialysis can lead to some side effects. Generally speaking, the following adverse effects can be commonly seen.
FatigueIt is related to a strict diet plan, loss of kidney function, deficiency of nutrition and so on.
Muscle cramps The occurrence of muscle cramps has close connection with fluid loss during dialysis.
Itchy skin This symptom is related to high levels of toxins in the body. When it occurs, do not scratch it.
Infections Before dialysis is used, an access to the blood vessels should be made. In this condition, patients may become susceptible to infections. Additionally, other discomforts like low blood pressure, joint pain, sleep problems and so on can also occur.
To be honest, dialysis can not cure kidney failure. Even if it is commonly used, it can help expand the survival periods of patients by discharging wastes and alleviating symptoms.
Usually, your doctor will provide you a personalized dietary plan according to your condition. When eating foods, remember to: eat certain amounts of high-quality protein foods, watch the consumption of potassium intake, pay attention to the fluid intake, avoid salted foods, eat some fresh fruits and vegetables and so on.
1.For people with high blood pressure and diabetes, it is necessary to monitor blood pressure and blood sugar level regularly.
2.Patients should not quit this treatment without doctors’ permission, otherwise, high levels of toxins will build up in the body and the condition will be aggravated.
