Drinking water could be beneficial to patients with low blood pressure

01.12.2004


Ordinary tap or bottled water could help people suffering from low blood pressure who faint while standing, claim researchers from Imperial College London and St Mary’s Hospital.

According to research published in the latest issue of Journal of Neurology, Neurosurgery and Psychiatry, drinking two glasses of water can raise blood pressure, potentially providing a solution for patients with low blood pressure while standing, caused by autonomic failure. Autonomic failure is where parts of the nervous system, responsible for the control of bodily functions not consciously directed, such as blood pressure, heart rate and sweating, do not function properly.

Professor Christopher Mathias, from Imperial College London and St Mary’s Hospital, and the senior author of the research, comments: “This surprising discovery that water can have such an effect on blood pressure could help us to treat both sufferers of autonomic failure, and many people who suffer from low blood pressure generally, especially those who faint, such as with vasovagal syncope.”



The researchers looked at 14 patients with autonomic failure, and measured their blood pressure while lying and standing, before, and 15 and 35 minutes after drinking 480ml of distilled water. When asked to stand, before drinking water, this caused a fall in blood pressure.

The 14 patients were divided into two groups, seven of whom had multiple system atrophy (MSA), while the other seven had pure autonomic failure (PAF). MSA is a neurodegenerative disease marked by a combination of symptoms affecting movement, blood pressure, and other body functions. PAF is a disorder affecting only the autonomic nervous system. They both often present in middle to late life.

The patients then drank water causing a significant rise in blood pressure. For the patients with PAF it took five minutes for a significant rise in blood pressure to be recorded, and for patients with MSA it took 13 minutes. In both the fall in blood pressure and symptoms of low blood pressure, was reduced while standing.

Professor Mathias adds: “While autonomic failure itself is generally not life threatening, it can have a significant impact on an individual’s quality of life. People with low blood pressure caused by autonomic failure are at a greater risk of fainting when standing upright, after food or even after mild exertion. This can affect their life in many ways, stopping them from driving, or in extreme cases, from being able to work. This discovery could be of considerable use in helping these patients to understand why this happens. It may also benefit the many without autonomic failure who faint as a result of low blood pressure.”

The research was supported by a grant from the Sarah Matheson Trust Autonomic Disorders Association.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
