Blood Is Often Clotting During The Hemodialysis Process?

Good afternoon, I am a hemodialysis patient who has undergone the hemodialysis process for 2 years, but lately my blood clotting frequently during the HD process. NI want to ask, what factors cause blood clotting? What foods should I avoid to prevent blood clotting? The nurse said it was because I was still drinking ice water. Is that true?

Hello Hadi,

The process of hemodialysis is carried out by draining blood from the body into a tube (dialyzer) consisting of two compartments - functions like a kidney, then flows back into the body. Blood outside the body will be more prone to clotting. Some of the factors that cause clotting during hemodialysis are:

Low blood flow, due to blockage of the dialyzer or access to small blood vessels. Blood contact with synthetic materials in the blood line (a tube to supply blood to and from the dialyzer) The hypercoagulable nature of the blood of people with kidney disorders causes the blood to become more concentrated. The use of drugs such as nitroglycerin, excessive administration of clotting erythropoietin can cause the dialyzer machine to stop and possibly have to replace the dialyzer. Clotting that enters the body is also dangerous because it can cause embolism. Therefore, to avoid this, in the hemodialysis process an anticoagulant (anti blood clotting) is used. The anticoagulant used is usually heparin. In addition, there are several hemodialysis machine settings that medical personnel can do to reduce the possibility of clotting.

There are no foods that can specifically cause blood clotting, but there are some food recommendations for patients undergoing hemodialysis, namely:

Limiting the intake of foods containing potassium, for example bananas, potatoes, avocados, tomatoes Limiting the intake of foods containing phosphorus, such as milk, cheese, liver, sardines Limiting salt intake Adjusting the amount of fluids drunk per day In patients with chronic kidney disease, usually the diet given is low in protein. However, patients who have undergone hemodialysis are advised to increase protein intake, for example meat, eggs, fish. Regarding the diet and foods that should or should not be eaten during hemodialysis, it is better if you consult again with an internal medicine specialist and a nutrition specialist who treats you. The adjustment of food portions and composition is different for each patient.

Hopefully the explanation above is useful.
