Fructose intolerance could be the culprit in unexplained abdominal pain and gas

21.10.2002


Researchers recommend testing symptomatic patients for the condition



Researchers at the University of Kansas Medical Center (Kansas City) urge physicians to consider adding fructose breath testing to their diagnostic strategy for patients with unexplained abdominal pain, gas, diarrhea, and intestinal rumbling or gurgling. The recent study’s results, presented at the 67th Annual Scientific Meeting of the American College of Gastroenterology, indicate that fructose malabsorption occurs in a significant proportion of healthy adults.

Fructose -- the simple sugar found in honey, many fruits, and some soft drinks -- is one of the principal sweeteners in the Western diet. Not everyone has the ability to absorb fructose properly, however, and now researchers are discovering that it may play an important role in the onset of common gastrointestinal symptoms, such as bloating, cramps, and diarrhea. These symptoms arise when the fructose is allowed to pass through the digestive tract to the colon, where some bacteria can use the sugar as a food source. Unfortunately, in the process, hydrogen gas is liberated.


After the subjects were given 25 grams of fructose, which is about how much is in a 12-ounce can of soda sweetened with high fructose corn syrup, the researchers collected breath samples. The analysis revealed an abnormal level (greater than 20 parts per million) of hydrogen gas in nearly one-half of the subjects. Hydrogen gas would not be present in breath unless fructose was not digested normally. On a subsequent day, the subjects received 50 grams of fructose, and about three-quarters had hydrogen levels greater than 20 parts per million.

"When given levels of fructose commonly consumed in the Western diet, a significant number of

our subjects had both objective and subjective evidence of fructose malabsorption, meaning that the breath analysis showed hydrogen in excess of 20 parts per million and they had symptoms like gas and diarrhea," said Peter Beyer, M.S., R.D., of the Dietetics and Nutrition Department at the University of Kansas Medical Center. "When patients present with such symptoms, doctors should consider adding breath analysis for fructose intolerance to the arsenal of routine diagnostic tests."

Last year, at ACG’s 66th Annual Scientific Meeting, Young K. Choi, M.D. and colleagues from the University of Iowa performed fructose breath tests on 219 patients with unexplained gas, bloating, and pain. The analysis revealed the abnormal presence of hydrogen or methane gas in 78 percent of the patients and gastrointestinal symptoms in 58 percent.

"If a patient is found to be fructose intolerant and symptomatic, the doctor may recommend a low-fructose diet," said Beyer. "But in severe cases, antibiotic therapy may be required to provide relief."

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
