Weight Loss Surgery Risk: Brain Damage Posted by: "wxchickster" [email protected] wxchickster Tue Mar 20, 2007 9:05 am (PST) Weight Loss Surgery Risk: Brain Damage Vitamin B1 Deficiency Suspected; Early Diagnosis Key http://www.webmd. com/diet/ news/20070312/ weight-loss- surgery-risk- brain-damage? ecd=wnl_wct_ 031907 By Daniel J. DeNoon WebMD Medical NewsReviewed by Louise Chang, MDMarch 12, 2007 -- After weight loss surgery, some patients risk brain damage from vitamin B-1 deficiency, researchers report. Too little vitamin B-1 -- thiamine -- causes a syndrome called Wernicke's encephalopathy. It's most often seen in malnourished alcoholics. If treated right away with vitamin B-1 shots, patients quickly recover. But if the syndrome isn't recognized quickly, it can result in permanent brain damage. And that can be a problem, says Wake Forest University researcher Sonal Singh, MD. Singh and Abhay Kumar, MD, of the University of Iowa, found 32 reports of Wernicke's encephalopathy in weight loss surgery patients. "Early diagnosis is essential," Singh tells WebMD. "Yes, thiamine shots are helpful. But you get full recovery only when it is given early. Once [advanced symptoms] develop, there is going to be neurological damage." Singh and Kumar report their findings in the March 13 issue of the journal Neurology. Tricky Symptoms Wernicke's encephalopathy has three classic symptoms: jerky, uncoordinated movement; uncontrollable eye movements; and mental confusion. That sounds easy to recognize. But not all weight loss surgery patients who develop the syndrome get all three symptoms. And some patients have unusual symptoms, such as hearing loss, weakness, convulsions, and tingling or numbness in the arms and legs. Symptoms of Wernicke's encephalopathy most often occurred four to 12 weeks after weight loss surgery. However, one case began a year after surgery, and another started only two weeks after surgery. There's one major warning sign for weight loss surgery patients: frequent vomiting. Twenty-five of the 32 reported patients were vomiting after their surgery. However, not all the patients had this symptom. And many developed vitamin B-1 deficiency even though they were taking oral thiamine supplements, suggesting that deficiencies in other nutrients may also play a role. How often do weight loss surgery patients get Wernicke's encephalopathy? That isn't yet known. Singh says it's an issue that clearly needs study. "Maybe giving shots of thiamine after surgery would prevent this," Singh says. "We might do it preventively rather than waiting for symptoms to appear. That, too, needs to be studied." Bariatric surgeon Ioannis Raftopoulos, MD, assistant professor of surgery at the University of Pittsburgh, says he regularly monitors thiamine levels in his patients and routinely gives his patients thiamine supplements, either orally or by monthly injections. The result: Raftopoulos says he has never had a patient develop Wernicke's encephalopathy. "This kind of thing only happens when a patient has been vomiting for weeks," Raftopoulos tells WebMD. "That kind of neurological impairment means a patient has had a lot of problems for a long time. That is why the key here is patient follow-up. All my patients have my personal beeper number so they can contact me immediately, before there is a serious problem." Singh says patients should immediately call a doctor if, after weight loss surgery, they have coordination problems -- especially changes in their gait -- or any changes in their hearing or vision.

I've read this previously. Thanks for the info.

Thanks for the info. I've seen articles about this also....so to help prevent this, I make sure to take my B-complex every day and I've added a B1 (Thiamine) supplement to my routine - just to make sure I'm getting in enough. My doctor also checks for this on his labs, so far I've not had any problems. Take care of yourselves everyone!! Make sure you are getting in your vitamins and nutrients....and see your surgeon and PCP on a regular basis! Have those labs drawn and keep up with your numbers. I hate to say it, but a lot of times patients see trends happening before the doctors.....so keep a copy of your labs and know what the numbers mean. Most of the time you will see either H or L next to a result indicating a High or a Low. Watch for a small but steady decline in numbers. Do something before it gets critical..... you all!! Susan
