Bulimia May Result from Hormonal Imbalance

05.01.2007
Bulimia is normally regarded as a mental illness that should be treated with cognitive behavioural therapy (CBT).

A newly published thesis from Karolinska Institutet in Sweden, however, shows that the condition depends in certain cases on a hormonal imbalance that can be corrected with common oral contraceptives.

"We have shown that one third of female bulimics have metabolic disorders that may explain the occurrence of the eating disorder. These disorders may in certain cases express the hormonal constitution of the patient, rather than any mental illness", says Dr Sabine Naessén about the research results that are presented in her doctoral thesis.

Bulimia nervosa, compulsive overeating, is probably the most common form of eating disorder, and it is approximately ten times more common in women than in men. The condition is normally considered to have psychological causes, and it is for this reason normally treated with cognitive behavioural therapy and antidepressive drugs.

The results that Dr Naessén has obtained show that bulimia is a complex condition that contains hormonal and genetic components, in addition to psychological components. The bulimics in the studies had higher levels of the male sex hormone testosterone and lower levels of the female sex hormone oestrogen than healthy subjects in the control group had. Testosterone is directly involved in the normal appetite regulation of the body, and an increased level may lead to an increased feeling of hunger.

The testosterone level of patients with bulimia could be reduced by treating these patients with oestrogen-dominated oral contraceptives. The result was that the craving for fat and sugar decreased, as did the feeling of hunger, in approximately half of the bulimics after as short a period of treatment as three months. Three subjects became completely free of the eating disorder as a consequence of the treatment.

"This is a very strong effect. Hormone treatment may very well be an alternative to cognitive behavioural treatment", says Dr Naessén.

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...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
