Can Bariatric Surgery Lead to Severe Headache?

23.10.2014

Bariatric surgery may be a risk factor for a condition that causes severe headaches, according to a study published in the October 22, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.

In the study, gastric bypass surgery and gastric banding surgery were associated with later developing a condition called spontaneous intracranial hypotension in a small percentage of people.

Spontaneous intracranial hypotension is often caused by a leak of the cerebrospinal fluid (CSF) out of the spinal canal. The leak causes low pressure of the spinal fluid, triggering sudden headaches in the upright position, which are relieved when lying down. Other symptoms include nausea, vomiting, neck stiffness and difficulty concentrating.   

“It’s important for people who have had bariatric surgery and their doctors to be aware of this possible link, which has not been reported before,” said study author Wouter I. Schievink, MD, of Cedars-Sinai Medical Center in Los Angeles, Calif. “This could be the cause of sudden, severe headaches that can be treated effectively, but there can be serious consequences if misdiagnosed.” 

For the study, researchers compared a group of 338 people with spontaneous intracranial hypotension to a control group of 245 people with unruptured intracranial aneurysms. A total of 11 of the 338 people with spontaneous intracranial hypotension, or 3.3 percent, had previously had bariatric surgery, compared to two of the 245 people with intracranial aneurysms, or 0.8 percent. 

Schievink said body weight plays an important role in CSF pressure. The typical person with spontaneous intracranial hypotension has a tall and lanky build, while obesity is a risk factor for intracranial hypertension, or high CSF pressure. “While more research is needed to understand the relationship between body weight and spinal pressure, it’s possible that the loss of fat tissue may uncover a susceptibility to spontaneous intracranial hypotension,” Schievink said.  

Of the 11 people with bariatric surgery and spontaneous intracranial hypotension, nine had no more symptoms after treatment, while symptoms persisted for two. The symptoms started from three months to 20 years after the bariatric surgery, and participants had lost an average of 116 pounds during that time.

The American Academy of Neurology, an association of more than 28,000 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, stroke, migraine, multiple sclerosis, brain injury, Parkinson’s disease and epilepsy.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
