An estimated 100,000 recreational scuba divers around the world have diabetes. But low glucose levels under water can lead to erroneous decisions or even unconsciousness. Given that scuba divers always have buddies, the risk extends to a second person as well.
Norway, Australia, New Zealand and a number of other countries prohibit diabetics from scuba diving, whereas Sweden, the UK and the United States restrict it.
A doctoral thesis by Peter Adolfsson, Senior Physician at the Queen Sylvia Children’s Hospital, at Sahlgrenska Academy presents a technique that may enable diabetics to scuba dive safely anywhere in the world.
A tiny needle is fastened a little more than one centimeter beneath the skin. A sensor at the top of the needle measures glucose values in the subcutaneous fat every tenth of a second, recording and transmitting the data to a monitor once every five minutes. If the values rise or fall by a certain percentage that has been adapted to the particular individual, the monitor sets off an alarm.
The needle remains in place for up to a week before it has to be changed. At that point it will have recorded glucose levels 2,016 times.
“A physically active diabetic is always at risk of developing high or low glucose levels,” Dr. Adolfsson says. “However, it is difficult, sometimes impossible, to monitor the levels during the course of an activity."
“This technique will enable some diabetics to scuba dive with tubes, and it can definitely offer support for type 1 diabetics who participate in football, floorball, cross-country skiing, golf and other sports.”
“Physical activity is important for everyone, and type-1 diabetics are no exception,” Dr. Adolfsson says. “My hope is that this technique will allow diabetics to scuba dive anywhere in the world, as well as to lead more active lives in other respects.”
Dr. Adolfsson, who was the official physician of the Swedish women’s national football team for nine years under Marika Domanski Lyfors, has participated in three European Championships, two World Championships and one Olympic. He defended his thesis, Recreational Scuba Diving and Type 1 Diabetes – Glucose Control during Physical Exercise, on September 14.Contact:

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
