blood becomes thicker

One of the problems of too much blood / increased red blood cell
production / thick blood is heart problems.
Lowering of too much blood was and is accomplished by blood donation.

Addressing 'thick blood' lowers the death rate to zero.

BLOODLETTING IN PNEUMONIA
John Haddon
BLOODLETTING IN PNEUMONIA.
Sir, Dr. Balms's communication in the Journal of June 5th, p. 970,
telling how he treats some cases of pneumonia, deserves to be
noticed.
It was the late Professor John Hughes Bennet who first advocated the
expectant treatment of pneumonia, and his book on the subject was
translated into many languages.
I acted as his resident in the clinical wards of the Edinburgh Royal
Infirmary, and , by his directions, I occasionally bled patients.
Bennet would have bled the cases Dr. Balm describes , and if the idea
is original on his part , he deserves credit.
Talking about his letter with a medical friend , he told me that he
had a patient whose nose bled profusely; he failed to stop it, and
the
late Dr. Joseph Bell was consulted he told my friend that his father
would , in such a case , have opened a vein, and that was what Dr.
Joseph Bell did.
He did not take more than two tablespoonsfuls of blood , and there
was
no more bleeding from the nose.
Our grandfathers used to be bled every spring, and I have heard
Professor Bennet tell of the row of patients waiting to be bled.
Lanquid and lazy before being bled, they felt as if their youth were
renewed by the bleeding.
I heard Sir T. Clifford Allbutt tell of having had a patient
suffering
from a pulse of very high tension, who was kept for a year by one
venesection; in these days of so-called sudden death from heart
failure or apoplexy , which I look upon as an opprobrium to the
physician, it would be well to resort to an annual bleeding aagain,
unless the profession can be converted to the views set forth in my
book which proves that food is the chief cause of disease, and
restricts the quantity , as well as changes the quality , of the
patients food.
In what has been called "idiopathic anasarca" we have a neurosis ,
due
to what the ancient physicians called plethora, which was just too
much blood, and which venesecton removed.
Such anasarca is almost universal after middle life, and I have found
it in some quite young , proving that even the youngest may be
injured
by the food they eat.
Such facts ought to encourage the study of dietetics which the
General
Medical Council would do well to make a compulsory subject of
examination for every licence to practice medicine. -- I am, etc.,
Hawick June 7th, John Haddon, M.D.

Study Involving Survival of Congestive Heart Failure Patients and
Blood Volume Measurement Using the BVA-100

New York, NY, May 24, 2004 – Daxor Corporation (AMEX: DXR),
a medical instrumentation and biotechnology company, today
announced a new study involving blood volume measurement and
the survival of congestive heart failure patients.
The study, conducted at the Columbia Presbyterian Medical Center,
ranked as the #1 hospital in the NY region, was published in The
American Journal of Cardiology (2004;93:1254-1259).
The study, authored by Dr. Stuart Katz , currently an Associate
Professor at Yale Medical School , and Dr. Ana- Silvia Androne,
et al. utilized the BVA-100 Blood Volume Analyzer to measure the
degree of blood volume expansion in congestive heart failure patients
and the eventual outcome of these severely ill patients.
The patients had a median follow up for a total of 719 days.
This is the largest published study measuring blood volume and
patient
outcomes.
Congestive heart failure is the number one cause for admission to
hospitals for patients over 65 years of age and results in annual
healthcare costs exceeding $38 billion.

The study is notable for a number of significant findings.
The study followed severely ill congestive heart failure patients for
a
median follow up of 719 days.
During the first year, the major finding was a 39% death rate in
patients
that were hypervolemic (excess blood volume) vs. 0% death rate for
those who were normovolemic/hypovolemic (normal blood volume/mildly
reduced blood volume).
For those hypervolemic patients that were followed fora median
duration
of 719 days, the death rate was almost 55% vs. 0% for those patients
who were normovolemic to slightly hypovolemic.

The second finding was based on comparing the ability of a
cardiologist when performing a comprehensive physical examination to
evaluate whether the patient had hypervolemia, normovolemia or
hypovolemia.
The study found that physicians were only correct 51% of
the time in categorizing the blood volume status of the patient.
Another finding was that the systolic blood pressure for the
hypervolemic group was significantly lower as compared to that of the
normo/hypovolemic group.
This may be related to Vasodilators, which are commonly used to treat
congestive heart failure.
An additional observation was that patients in the normo/hypovolemic
group had better kidney blood flow than the hypervolemic patients.
Dr. Joseph Feldschuh, President of Daxor, who is a cardiologist,
stated “At the present time, it is very difficult for experienced
physicians to judge when they have over-treated or under- treated
patients.
More precise treatment has the potential for reducing the
frequency and extent of hospitalization of congestive heart failure
patients.
The treatment for hypervolemia is different than the treatment for
hypovolemia in heart failure.
Dr. Androne and Dr. Katzs’ study demonstrates the difficulty a
physician faces in distinguishing these conditions and administering
optimum therapy.
The difference in the survival rate between the different groups of
heart
failure patients suggests that adjusting medical therapy in a heart
failure
patient to normalize his/her blood volume can improve the longevity
of
the patient.”


Daxor Corporation manufactures and markets the BVA-100, a semi-
automated Blood Volume Analyzer.
The BVA-100 is used in conjunction with a single use diagnostic kit,
and measures blood volume to within a 98% accuracy.

This says bloodletting and / or menstruation alleviates
accumulation of blood and hyperviscosity / 'thick blood' and
should be used as a **selling point** in blood donation centers.


Alleviative Bleeding: Bloodletting, Menstruation
and the Politics of Ignorance in a Brazilian Blood
Donation Centre
Emilia Sanabria
Centre Edgar Morin (EHESS/CNRS),


This article focuses on blood donation as a form of bloodletting
in a context where donation is commonly seen to alleviate the
symptoms of `thick blood'.
It deals with the gendered aspects of blood donation, and the
parallels drawn between donating blood and menstruating.
Women are seen not to need to donate blood as much as men,
who, in the absence of menstruation, are more prone to thick
blood and require a means to expunge the ensuing excess.
While blood donation professionals strive to reconstruct donation
as a selfless and ungendered act, counterposing the `facts' of
arterial blood circulation to local blood-lore and beliefs, lay
understandings challenge this construction in the use they make
of blood donation centres or by reiterating the personalistic and
gendered dimensions of donation.
The article explores cases of patients who use hormonal
contraceptives which suppress menstruation and express concerns
over the resulting accumulation of blood in the body.
It considers how blood donation is adopted by some women as
a means of dispelling both the perceived inconveniences of menstrual
bleeding and its swelling effects.
Such literalized engagements with medical technologies reveal a
conception of the body as a permeable, malleable and recipient-like
enclosure.
These views are often characterized as `ignorance' by medical
practitioners, where ignorance is seen to derive not only from the
absence
of knowledge, but from the presence of the wrong kind of knowledge.
