46
IBS Management Rome IV emphasizes that the best management for functional GI disorders requires a ______ approach which takes into consideration * **Early life influences**: g\_\_\_\_\_, c\_\_\_\_\_, en\_\_\_\_ * **Psychosocial factors**: st\_\_\_\_, per\_\_\_\_\_\_, psychological state, cop\_\_\_, social su\_\_\_ * **Physiology**: m\_\_\_\_, sen\_\_\_\_, i\_\_\_\_\_ function, microf\_\_\_\_, food, diet

IBS Management Treatment is purely symptomatic and includes dietary modifications, medications, behavioral therapy, education and reassurance * Establish effective relationship with pt: ed\_\_\_\_\_ and re\_\_\_\_ is key * Symptom d\_\_\_\_ (timing, associated sx, feelings) * Predominate diarrhea: f\_\_\_\_ to bulk stool; **lo\_\_\_\_\_** 2-4 mg QID (45 min before meals) can be helpful * Constipation: dietary fiber; laxative- **M\_\_\_\_\_** preferred
* Establish effective relationship with pt: education and reassurance is key * Symptom diary (timing, associated sx, feelings) * Predominate diarrhea: fiber to bulk stool; **loperamide** 2-4 mg QID (45 min before meals) can be helpful * Constipation: dietary fiber; laxative- **Miralax** preferred
48
IBS Management Cont. * Gas/Bloating: diet * Abdominal \_\_\_\_\_\_: Bentyl 10-20mg TID, Levsin sl TID prn or Levbid * St\_\_\_\_\_ reduction, \_\_\_feedback, ex\_\_\_ * Moderate to severe IBS, consider Rx (1) * Follow-up in \_*-*\_ weeks then every \_*-*\_ mos

Role of Serotonin in IBS Serotonin is a neurotransmitter and a hormone that plays an important role in numerous life processes, including mood, sleep, appetite, temperature regulation, pain perception, sexual behavior, and the secretion of other hormones. Although most of the body's serotonin is found in the ___________ system and in \_\_\_\_\_\_, its most well-known effects are in the \_\_\_\_\_. Serotonin is an important signaling molecule in the gastrointestinal (GI) system, where it functions to initiate gut m\_\_\_\_\_, allow the stomach to ex\_\_\_\_, and transmit information to the \_\_\_\_.
Although most of the body's serotonin is found in the gastrointestinal system and in blood platelets, its most well-known effects are in the brain. Serotonin is an important signaling molecule in the gastrointestinal (GI) system, where it functions to initiate gut motility, allow the stomach to expand, and transmit information to the CNS.

Constipation women
51
Common Causes of Constipation **Common causes (mostly functional)** * ______ urge to defecate (most common) * inadequate f\_\_\_\_ and fl\_\_\_\_ in diet; sed\_\_\_\_\_ * met\_\_\_, en\_\_\_\_, n\_\_\_\_, colorectal disorder **Elderly patients:** * Diminished vit\_\_\_\_, decreased act\_\_\_\_, consequence of _____ illness and medications, poor d\_\_\_\_ habits, and decreased fl\_\_\_ intake
**Common causes (mostly functional)** * ignoring urge to defecate (most common) * inadequate fiber and fluids in diet; sedentary * metabolic, endocrine, neuro, colorectal disorder **Elderly patients:** * Diminished vitality, decreased activity, consequence of chronic illness and medications, poor dietary habits, and decreased fluid intake
52
Rome Criteria for Constipation Functional constipation categorized under new Rome criteria IV * IBS subtypes (constipation and diarrhea) are now based on abnormal _____ type occurring at least \_\_% of days
* IBS subtypes (constipation and diarrhea) are now based on abnormal stool type occurring at least 25% of days New diagnoses added to this edition include reflux hypersensitivity syndrome, cannabinoid hyperemesis syndrome (CHS), opiod-induced constipation (OIC), and narcotic bowel syndrome (NBS). \*\* \*\*“Many purists would say [these] are not really functional because [they have] a cause, but we have to rethink ... this in the 21st century,” Drossman said. “What we’re really saying is that these are conditions that will mimic other so-called functional GI conditions, which ... may have specific etiologies, and [they are] also consistent with our [new] definition [for functional GI disorders].”
53
Rome IV IBS Subtypes * Subtypes are based on how _____ you experience very ____ or very ____ stools. * The percentages are now based on stool ___ on days with at least one (1) * In Rome III, the percentages were based on ____ stools.
* Subtypes are based on how frequently you experience very loose or very hard stools. * The percentages are now based on stool form on days with at least one abnormal bowel movement. * In Rome III, the percentages were based on total stools.

1. **Restrictive** - restricts amt of food ingested * Dec appetite, Early satiety, Slows digestion * Sleeve gastrectomy, Adjustable gastric banding, Roux-en Y gastric bypass 2. **Malabsorptive** - limits digestion and absorption * Decreases length of intestine exposed to digested food * 25% of fat is absorbed * Biliopancreatic Diversion/ duodenal Switch (least commonly performed) * All operations can be performed open or laparoscopically

**Surgical wt loss in which the stomach is reduced to 25% of its original size, by surgical removal of a large portion of the stomach along the greater curvature (most common)** * Limits amount of food eaten and reduces hunger sensation because portion of stomach that produces \_\_\_\_\_\_, hunger stimulating hormone, is removed * Fastest growing wt loss sugery in North America and Asia * May be converted to gastric bypass or duodenal switch for ____ wt loss * Quicker wt loss than lap band * Reversible?
Gastric Sleeve * Limits amount of food eaten and reduces hunger sensation because portion of stomach that produces Ghrelin, hunger stimulating hormone, is removed * Fastest growing wt loss sugery in North America and Asia * May be converted to gastric bypass or duodenal switch for additional wt loss * Quicker wt loss than lap band * Not reversible
107
**A silicone band is placed around the upper part of the stomach, a small pouch is created; slows down gastric pouch emptying** * Early feeling of satiety/ surgical appetite suppressant; requires more patient effort for initial (1) than with gastric bypass or duodenal switch * Purely restrictve * Ad\_\_\_\_\_\_ restriction through mediport * Reversible? * Complications: sl\_\_\_\_\_, er\_\_\_\_\_, tubing dis\_\_\_\_\_\_ – *outdated*
Lap Band System * Early feeling of satiety/ surgical appetite suppressant; requires more patient effort for initial wt loss than with gastric bypass or duodenal switch * Purely restrictve * Adjustable restriction through mediport * Reversible (if necessary) * Complications: slippage, erosion, tubing disconnect – *outdated*

Roux-en Y Gastric Bypass = * Inacc\_\_\_\_\_\_ gastric remnant * Requires life long **(1) supplements** * Complications: d\_\_\_\_ing, stomal str\_\_\_\_\_, per\_\_\_\_\_ * Reversible?
**A Gastric pouch of 15-20ml and 2 anastomoses are created to bypass 95% of the stomach an duodenum** * Inaccessible gastric remnant * Requires life long vitamin supplements * Complications: dumping, stomal stricture, peritonitis * Theoretically reversible, but very difficult
