In patients with end-stage renal disease (ESRD) receiving dialysis, elevated blood pressure is common and poorly controlled in general. 4 Although volume overload and sodium retention appear to be the main pathogenic mechanism of hypertension in this population, other factors such as increased arterial stiffness, activation of renin-angiotensin-aldosterone system, sleep apnea, activation of sympathetic nervous system, and use of recombinant erythropoietin may be also involved. 5
What happens if your blood pressure is too high during dialysis?
It can occur when too much fluid is removed from the blood during hemodialysis. This causes pressure to drop, and nausea and dizziness can result. Tell your dialysis team if you experience any of these issues. Medication for high blood pressure should usually not be taken before treatment, unless the doctor prescribes it that way.
Why is blood pressure checked on dialysis patients?
Blood pressure is checked in all medical settings, but it is even more significant for patients on dialysis. Low blood pressure, or hypotension, can create problems during dialysis. Know the symptoms so you can alert staff and get treatment quickly.
What are the risk factors for low blood pressure during dialysis?
Risk Factors. Certain patients are more likely to see debilitating drops in their blood pressure during dialysis. While these observations do not suffice as acceptable medical evidence, a quick review of the literature reveals that certain patients are more likely to see blood pressure drops. Patients with too low dry weight.
How do you manage high blood pressure on peritoneal dialysis?
Managing high blood pressure in peritoneal dialysis patients. Keeping the blood pressure in optimal range first requires that a person’s fluid be managed well. Too little fluid in the body may cause the blood pressure to be low, and can be associated with symptoms such as leg cramps, nausea and lightheadedness.
Why is my blood pressure high during dialysis?
intradialytic hypertension is caused by an increase in stroke volume and/or vasoconstriction with an inappropriate elevation in PVR during hemodialysis; therefore, it appears plausible that stimulation of the sympathetic nervous system should contribute its development.
How do you control high blood pressure during dialysis?
Dihydropyridine calcium channel blockers (CCBs) are widely used to reduce BP for dialysis patients as well as general hypertensive population. They are effective for overhydrated state commonly observed in HD patients [29].

Hypertension is common among patients with chronic kidney disease and often remains poorly controlled in hemodialysis patients. Recently, a large cohort study found that the variability of blood pressure (BP) within patients was at least as great as variability seen between patients.
Can you have dialysis with high blood pressure?
People who are on dialysis need blood pressure medicines to ensure their blood pressure remains under control. Blood pressure is caused by too much fluid in the body, and reducing the dry weight can help a patient on dialysis. The problem of high blood pressure has become more common now than ever before.
How to prevent hypotension during dialysis?
To prevent hypotension during dialysis, take in adequate protein, as it helps fluid move from tissues into the bloodstream. The protein level is usually reflected as albumin in the lab. Patients are often encouraged to increase consumption of fish, eggs and chicken when albumin is low.
How to avoid hypotension?
Another important way to avoid hypotension is to keep fluid intake low between treatments so the change in body fluid isn’t so drastic. Removal of large amounts of fluid makes the treatment much harder on the heart. Weight gains between treatments should be no more than 5% of dry body weight.
What is the difference between systolic and diastolic blood pressure?
The first, systolic blood pressure, represents the “working” phase of your heart, or the pressure in your blood vessels when your heart contracts. The second, diastolic blood pressure, represents the pressure in your blood vessels when your heart “rests” between beats. Though individuals vary, generally a blood pressure before dialysis should be ...
Can you take BP medication at night?
If a patient takes BP medication at night, and then arrives at dialysis with very high blood pressure in the morning, either: 1) fluid gains are too high or 2) the evening dose is not adequate. This is dangerous. Patients’ checks of blood pressure at home morning and evening can help the doctor optimize timing and dosages.
Does dialysis medication increase urine output?
One medication may increase urine output, another relaxes the blood vessels, and another improves heart rate, contractions or output. Some medications are available in combination, so patients may want to ask their doctor for options. Blood pressure medications can affect dialysis.

What happens when you exchange dialysis?
When patients do an exchange (the process of filling, dwelling and draining dialysis solution), the pressure from the dialysis solution in the peritoneum pushes against these already weak muscles. This pressure could cause a tear, and organs from the abdominal cavity could emerge through the opening.
What are the side effects of PD?
Side effects of PD. 1. Hernia. A hernia is a potential side effect of PD, a type of home dialysis treatment. The muscles of the abdominal wall protect the internal organs and keep them in place. The insertion of a catheter—positioned inside and outside of the body to allow dialysis solution into and out of the abdominal cavity—can weaken these ...

Weight gain can also come from the sugar in the dialysis solution being absorbed by the body and lead to extra pounds. Talk to a renal dietitian and nurse to learn how to balance nutritional needs and achieve comfort while on PD.
Can you eat phosphorus on dialysis?
Phosphorous isn't effectively removed by dialysis, so foods with phosphorus are restricted on the renal diet. Following the dietitian's guidelines and taking a phosphorus binder can help prevent this side effect. Dialysis patients are also prone to dry skin, which can be the cause of itching.
Can PD catheters cause nausea?
In PD, exchanges through the PD catheter must be done carefully to lessen the risk of infection. However, there's still a chance of peritonitis, which is an infection where the catheter is placed in the abdomen. Peritonitis can cause fever, nausea, vomiting and stomach pain.
Can hemodialysis cause muscle cramps?
Muscle cramps. Patients sometimes experience muscle cramps while undergoing hemodialysis. Occasionally, when fluid is taken out of the body at a fast rate during dialysis or too much fluid is removed, the muscles react by cramping. A doctor may be able to recommend some remedies. 6.
What is a drop in blood pressure during hemodialysis?
A drop in blood pressure is a common complication during hemodialysis. In medical jargon, the phenomenon is called intra-dialytic hypotension. It can be a debilitating problem, as it often requires cutting dialysis treatments short, leading to inadequate dialysis therapy.
