THE NEW DIGESTIVE HEALTH CENTERFrom the high-tech equipment to patient-friendly touches, every single detail in thenew GRHealth Digestive Health Center is part of center director Dr. Satish Rao’svision, years in the making.The center specializes in care and treatments for complex digestive health disordersas well as general gastroenterology problems that affect 25 percent of the population.Rao, for example, leads the Neurogastroenterology/Motility clinic, one of only 10 in thenation designated as a Center of Excellence by the American Neurogastroenterology andMotility Society. The clinic offers novel diagnostic tests and specialized treatments, notfound anywhere else in Georgia, for disorders that affect the movement and digestion offood from the esophagus to the colon.But Rao is perhaps most proud of the many patient-friendly features that were designedinto the new space. For example, restrooms are located next to colonoscopy prep rooms forpatient comfort, and prep and recovery rooms both feature TVs for entertainment.What patients won’t necessarily notice but will benefit as much from is high-techequipment from Philips that ensures continuous monitoring from prep through recovery,as well as piped-in CO2 and water irrigation/immersion, an important new advance thatmakes a huge difference in patient comfort andprocedure time during colonoscopies and wheninflating the bowel.“Our vision was to create a beautiful newregional care facility and a national center ofexcellence that caters to the specialized needsof patients with digestive health disordersand brings together our many services intoone convenient location,” said Rao. “Our newDigestive Health Center achieves that, and weare very proud to offer this facility to patientshere in the CSRA and beyond.” Digestive Matters, Spring 2015Advanced Endoscopy with Dr. Daram5Dr. Bogorad, first patient seen in the DHC clinic.

PATIENT TESTIMONIALSGastric SleeveStuck. That’s just how Pam Williams was feeling a few months ago. Not only was she unableto join her family for evening meals because her food became stuck and indigestible, but shewas stuck living with painful arthritis, severe reflux, and fatigue. This breast cancer survivoryearned for a normal and more active life, which led her to Dr. Brian Lane at GRHealth.As a result of lap band surgery, Pam spent almost four years eating “slider” foods with littleconsistency. These foods may have gone down more easily, but they were also causing Pam damageand additional weight gain. The lap band, which had become twisted, made it very difficult for Pamto eat foods with any consistency and often led to vomiting. Most days, Pam found herself exhaustedafter getting home from work, with little energy to do anything but sit and watch TV.Pam soon realized how vital it was that she have the lap band removed, not only for healthreasons, but to regain a normal and active lifestyle. Pam decided to make an appointment withLane at the Georgia Regents Center for Obesity and Metabolism. “During the first meeting I hadwith him, I knew and felt very comfortable,” she said. “Dr. Lane is a very knowledgeable and caringdoctor. He explained the gastric sleeve and exactly what would be done.”“Thanks to these caring nurses, physician assistant, andDr. Lane, I have a new lease on life!”Pam is now one month post-surgery, andshe is already seeing results. Within twoweeks, she began feeling the positive effects ofher gastric sleeve surgery. With 20 lbs. gone,she is noticing her clothes fitting more looselyand feeling much relief from the painfulpressure on her knees and joints. She is alsoexperiencing more energy and enjoying takingher new puppy on walks every day.When asked if she has advice for othersstruggling with weight issues, Pam said, “Itell them that the struggle is real, but there isa way to be helped. The gastric sleeve surgeryis a tool to help me reach my goals, and I amanxious to see where my journey takes me. Iam very pleased with the results so far!”“Dr. Lane, physician assistant, Amy, andall of the nursing staff have been amazing!”Pam continued, “They are a wonderful group,and words cannot express how grateful Iam. I could not have dreamed of a moreexperienced staff. Thanks to these caringnurses, physician assistant, and Dr. Lane, Ihave a new lease on life!” For more informationon the Center for Obesityand Metabolism, visitgrhealth.org/weightloss.Pam Williams6grhealth.org/digestivehealth

Fructose IntoleranceAs Jennie Montgomery made thewalk from her bathroom to thebedroom early one morning, it tookeverything in her to call out to her husband.That’s the last thing she remembered beforeblacking out from extreme pain.She had been dealing with unexplainedpain for over a month. “It hurt to walk. Iwould have to steel myself to walk frommy desk into the studio. I would listen toairchecks and noticed my shallow breathingbecause it hurt to inhale deeply,” she said. “Ieven wrote down on a little yellow Post-itnote three little symptoms I was feeling,knowing that if something happened thatKimberly, who sits two desks across from me,would know what was wrong.”After blacking out in her home thatweekend, Montgomery was rushed tothe hospital. After a weeklong stay, thedoctors and surgeons were unable to make adiagnosis. She left with questions unansweredand still in extreme pain. After discharge,Montgomery felt she was out of options.Taking her doctor’s advice, she made thedecision to undergo exploratory surgery.On the short drive from the hospital toTelevision Park, Montgomery received a call.Beth, a friend, fellow church member, andemployee at Children’s Hospital of Georgia,encouraged her to postpone the surgery. Shewanted her to see the doctors at GRHealthfirst. Beth arranged for an initial consult withDr. Todd Merchen. Merchen referred herto Dr. Satish Rao, Director of the GeorgiaRegents Digestive Health Center. “My firstvisit with Dr. Rao was wonderful, because he’sjust so compassionate and an extraordinarylistener. He is so relatable, and you knowthat he cares,” Montgomery said. Rao wasoptimistic and wanted to do a few more testsbefore considering surgery. Jennie called thesurgeon’s office that day and canceled hersurgery.Rao recommended the SmartPill and thatMontgomery take a hydrogen breath test. Asthe testing took place, Jennie rocked, doubledover in excruciating pain.When the test results came back, it wasdetermined she was suffering from fructoseand lactose intolerance.

THE GLUTEN CRAZEAre you gluten phobic or friendly?Gluten is a popular topic among selfproclaimed health gurus. Gluten isa protein composed of the prolamingliadin. Prolamins are storage proteins foundin the endosperm of grains. Some health“experts” or celebrities claim eating gluten is“not healthy.” Many new books and diet planshave been developed due to this craze. (SeePaleo Diet and Wheat Belly).Types of foods that contain gluten are:wheat (emmer, spelt, einkorn, karmut), wheatstarch (wheat bran, cracked wheat, wheatgerm, hydrolyzed wheat protein), barley, andrye. Alternatives to gluten are millet, rice,amaranth, buckwheat, sorghum, quinoa, andcorn.Celiac disease is an autoimmune disorderthat is caused by eating gluten. Approximately1 in 133 people in the United States hasceliac disease. Only people with celiac diseaseneed to avoid gluten. Their bodies treat glutenas a foreign substance, and this causes damageto the lining of the small intestine. Hence,gluten needs to be excluded from their diet.The damage caused by the immune responseto gluten reduces the absorptive capacity,resulting in malabsorption of nutrients;calcium, vitamin D, iron, and folate levelsmay each be reduced. This leads to symptomssuch as diarrhea, fatigue, weight loss, anemia,and skin rash. If you have any of theseunexplained symptoms, you should consultyour physician or seek a gastroenterologistreferral rather than experiment with a glutenfree diet.The United States does a great job atmarketing health “cures,” and unfortunately,gluten suffers because of this. Foods labeled“gluten free” mislead consumers into believingan item is healthier. Gluten free can bestamped on food labels that do not containgluten to begin with! Gluten-free labels aremarketed extensively in the food supply,ranging from eggs to mint candies. Thislabeling serves two purposes, which is toincrease the price of the product and give afalse sense of security to the consumer.Foods containing gluten, such as wholewheat bread or pasta, also contain fiber, whichis beneficial to digestive health. Fiber helpsprevent constipation by providing bulk tostool. Certain types of fiber act as a prebiotic,8“Only people with celiac disease need to avoid gluten.Their bodies treat gluten as a foreign substance.”which helps to feed the healthy bacteria in the colon. Fiber also promotes satiety, which can help aidweight loss.Some people may have wheat or fructan intolerance. Fructans are complex carbohydrates thatare present in wheat, onions, garlic, and artichokes. These individuals do not have celiac diseaseor an allergy to wheat but cannot digest these food items because of a lack of enzymes that breakdown these foods. This condition, like celiac disease, can be diagnosed from proper testing. Pleaseconsult your physician or seek a referral to a gastroenterologist who can order appropriate testing todiagnose this condition.Let’s set the record straight. Gluten is a type of protein in wheat that only needs to be restrictedin the case of celiac disease or gluten malabsorption. This requires definitive diagnosis by agastroenterologist. The rest of the population does not need to be concerned with restricting gluten.Restricting food items without supplementation may also lead to nutritional deficiencies, and hence,one should exercise caution.Andy Yurechko, RD Clinical Nutrition and Dietary Servicesand Food Intolerancesgrhealth.org/digestivehealth
