Is Blood Cleansing Safe? Insights on the Procedure and Its Risks - Internal Medicine

Could you please provide information regarding blood washing?


Hello Dr.
Ke: Recently, a friend from China underwent a blood cleansing treatment, where he spent four hours using a machine to draw out blood, cleanse it, and then return it to his body.
He described that they extracted an amount of fat equivalent to a can of beer.
I recall seeing reports that some politicians in Taiwan are undergoing this treatment.
Do you know which hospitals offer this service and whether there are any potential side effects? I hope you can provide some guidance.
Thank you!

Currently, plasmapheresis is only used for autoimmune diseases (which can generally be performed at medical centers), but the purposes of blood washing at other private clinics, such as fat removal, antioxidant effects, and asthma treatment, are not recognized as reasonable methods in current medical practice, and health insurance does not cover them.

More Info


Blood cleansing, often referred to as "blood washing" or "blood purification," is a procedure that has gained popularity in various parts of the world, including some regions in Asia. The concept behind this procedure is to remove impurities, toxins, or excess lipids from the blood, with the aim of improving overall health and well-being. However, it is essential to approach this topic with caution and a critical understanding of the medical implications involved.

Firstly, it is crucial to note that the human body has its own highly efficient mechanisms for detoxification and purification. The liver, kidneys, and lymphatic system work continuously to filter out toxins and waste products from the bloodstream. Therefore, the necessity and efficacy of artificial blood cleansing procedures are often questioned by medical professionals.
In terms of safety, any procedure that involves the manipulation of blood carries inherent risks. These risks can include infection, allergic reactions, and complications related to the equipment used. For instance, if the equipment is not properly sterilized, there is a potential risk of transmitting bloodborne pathogens, such as HIV, hepatitis B, and hepatitis C. Additionally, the process of drawing blood and reinfusing it can lead to complications such as air embolism, hemolysis, or adverse reactions to anticoagulants used during the procedure.

Regarding the specific case of your friend who underwent blood cleansing, it is important to consider the qualifications of the medical personnel involved and the facility where the procedure was performed. Procedures like these should only be conducted in licensed medical facilities with trained professionals who adhere to strict hygiene and safety protocols. If your friend experienced the removal of a significant amount of lipids, it raises questions about the method used and whether it was scientifically validated.

As for the potential for long-term side effects, there is limited research on the long-term consequences of blood cleansing procedures. While some individuals may report feeling better or experiencing temporary improvements in certain health markers, these effects are often anecdotal and not supported by rigorous scientific evidence. Moreover, the removal of certain components from the blood could potentially disrupt the body’s natural balance, leading to unforeseen health issues.

In conclusion, while the idea of blood cleansing may seem appealing, it is essential to approach it with skepticism and caution. The human body is equipped with its own detoxification systems, and any procedure that alters blood composition should be carefully evaluated for safety and efficacy. If you or anyone you know is considering such a procedure, it is advisable to consult with a qualified healthcare professional to discuss the potential risks and benefits, as well as to explore safer and more scientifically supported methods for improving health and wellness.
