  1. bowel movement Presented by: Abdullah Al-Ruwaita Abdullah Al-Manea Yousif Al-Ansari Supervised by: Prof. RiazQureshi, FRCGP

  2. constipation • Dif: hard, dry, lumpy stools that are difficult or painful to pass • Causes: - Congenital or Primary. - Secondary which includes: -Insufficient dietary fiber intake. -Inadequate fluid intake. -Decreased physical activity. -Side effects of medications. -Hypothyroidism. -Obstruction by colorectal cancer.

  3. Acute diarrhea • Dif: three or more loose or watery stools per day, without abdominal bloating, pressure, and cramps commonly referred to as gas. • Causes: • Infections: - Viral - Bacterial • - Parasites • Intestinal disorders • Reaction to certain medications

  4. Chronic diarrhea • Dif: as loose stools that last for at least four weeks, usually means three or more loose stools per day. • Causes: - Irritable bowel syndrome - Inflammatory bowel disease - Malabsorptionsyndromes - Chronic infections. 

  5. 1- Irritable bowel syndrome • Dif: is a gastrointestinal syndrome characterized by chronic abdominal pain and altered bowel habits in the absence of any organic cause. It is the most commonly diagnosed gastrointestinal condition.

  6. Epidemiology • prevalence of IBS in North America estimated from population-based studies is approximately 10 to 15 percent • in Europe found an overall prevalence of 11.5 percent • 2:1 female:male

  7. CLINICAL MANIFESTATIONS  • Chronic abdominal pain(as a crampysensation and abdominal pain) • Altered bowel habits(ranging from diarrhea, constipation) • Diarrhea (frequent loose stools of small, fecal incontinence and feeling of incomplete evacuation) • Constipation (Stools are often hard, may last from days to months)Other gastrointestinal symptoms • Other gastrointestinal symptoms(Upper GI symptoms)

  8. DIAGNOSTIC CRITERIA  • Rome III diagnostic criteria: • Recurrent abdominal pain or discomfort. • at least 3 days per month in the last 3 months associated with 2 or more of the following:

  9. DIAGNOSTIC APPROACH  • many disorders present with similar symptoms (r/o), • Routine laboratory studies (complete blood count, chemistries) are normal in IBS.

  10. "Alarm" or atypical symptoms which are not compatible with IBS include (red flags) : • Rectal bleeding • Nocturnal or progressive abdominal pain • Weight loss • Laboratory abnormalities such as anemia, elevated inflammatory markers, or electrolyte disturbances • Patients with one of these alarm symptoms require further imaging studies and/or colonoscopy

  11. Causes • It is not clear why patients develop IBS. Sometimes it occurs after an infection of the intestines. This is called post-infectious IBS. There may also be other triggers; • Brain-gut signal problems (thalamic activity). • GI motor problems (unpleasant stimuli). • Hypersensitivity (stimulation of various receptors in the gut wall). • Mental health problems (Such as anxiety, depression). • Bacterial gastroenteritis. • Small intestinal bacterial overgrowth. • Food sensitivity (food intolerance to certain foods). • Child Abuse

  12. Differential diagnosis • Crohn's disease • Ulcerative colitis • Diverticulosis • Celiac Disease • Lactose intolerance • Colon malignancy • Peptic ulcer disease • Biliary liver disease • Chronic pancreatitis • Medications • Lymphoma of the GI

  13. Treatment • Patient education: Education of the proposed mechanisms of IBS helps to validate the patient's illness experience and sets the basis for therapeutic interventions

  14. Dietary modification: dietary history may reveal patterns of symptoms related to specific foods. • Lactose(similarity that may occur in symptoms of IBS and lactose intolerance, an empiric trial of a lactose free diet should be considered ) • Exclusion of gas-producing foods  • Food allergies  • Gluten sensitivity  • Carbohydrate malabsorption • Fiber (increase in the intake of fiber is often recommended)

  15. Physical activity • Psychosocial therapies • Cognitive behavior therapy • Relaxation training • Gut-directed Hypnotherapy

  16. MEDICATIONS: • Antispasmodic agents • Mebeverine • Alverine • Dicyclomine (an anticholinergic) • Antidepressants (TCAs, SSRIs)

  17. Take home message • Mind and body often combine to increase the distress of IBS patients. • Psychological intervention worth considering. • IBS patients can be managed well by family physicians. • Don’t forget “red flags” for referral to GI specialist is a must !

  18. Inflammatory Bowel Disease • Inflammatory bowel disease (IBD) is comprised of two major disorders: 1.Ulcerative colitis (UC). 2.Crohn's disease (CD). •IBD can present at any age: –The peak :15 - 30 years. – A second peak 50 •Etiology is unknown but there are 3 main factors contributing to it : Genetic factors, environmental factors, diet.

  19. 1- Ulcerative colitis • Ulcerative colitis is characterized by recurring episodes of inflammation limited to the mucosal layer of the colon. •major symptoms of UC are: -Diarrhea -rectal bleeding     ( usually fresh blood ) -Tenesmus -passage of mucus -crampy abdominal pain

  20. DIAGNOSIS:  • No single modality is enough for Diagnosis . • Combination of clinical picture, laboratory,  Endoscopy, pathology. • Colonscopy findings: –The vascular markings are lost, petechiae, exudates, touch friability, and frank hemorrhage may be present. • –In Pathology,  biopsy shows : –Crypt abscesses. –chronic changes including branching of crypts, atrophy of glands, and loss of mucin in goblet cells

  21. MANAGEMENT: • –Rule out infection • –5 ASA (5-amino salicylic acids)-  therapy: •Rectal ( if the UC extend less than 20 cm ) •Oral ( if the UC extend more than 20 cm +) in combination with rectal  • –Corticosteroids:  •Systemic: Prednisolone •Local acting: enema. • –Immunomodulators : •Azithyoprine •Methotrexate • –Anti TNF therapy

  22. 2- Crohn's disease  • Is a disorder of uncertain etiology that is characterized by transmural inflammation of the gastrointestinal tract. • SYMPTOMS: –Fatigue. –Diarrhea.  –Abdominal pain. –Weight loss. –Fever. –Bleeding is very rare.

  23. DIAGNOSIS: • Colonoscopy: • Endoscopic features include focal ulcerations adjacent to areas of normal appearing mucosa along with polypoid mucosal changes that give a cobblestone • Wireless capsule endoscopy  • Serologic markers  •Inflamatory marker : ESR, CRP •Antibody tests : •Antineutrophilcytoplasmic antibodies (pANCA) > with UC •Anti-Saccharomycescerevisiae antibodies (ASCA)  > with CD • Stool markers — fecal calprotectin.

  24. complications: • The intestinal complications of Crohn's disease include the following: -Intestinal obstruction -Fistulas -Abscess -Hemorrhage (bleeding) - Unusual in Crohn's disease -Malabsorption -Carcinoma, Colonic disease increases risk of colon cancer • The longer you have Crohn's disease, the more likely you are to develop complications that can be fatal.

  25. Treatment: • The goals of treatment of Crohn's disease are to reduce the underlying inflammation, which then relieves symptoms, prevents complications, and maintains good nutrition. • Aspirin-like anti-inflammatory drugs (mesalamine) reduce the inflammation. • Corticosteroids reduce inflammation and suppress the immune system. • Antibiotics reduce inflammation indirectly by reducing infection. • Immunosuppressants suppress the immune system. • Surgery. (alternative).

  26. Celiac Disease • Celiac disease is a medical condition in which the absorptive surface of the small intestine is damaged by a substance called gluten. This results in an inability of the body to absorb nutrients: protein, fat, carbohydrates, vitamins and minerals, which are necessary for good health. • SYMPTOMS: –anemia. –chronic diarrhea. –weight loss. –Fatigue. –cramps and bloating. –irritability.

  27. DIAGNOSIS: • Screening • Biopsy: A definitive diagnosis can only be made by a small bowel biopsy.

  28. TREATMENT: • Celiac disease as yet has no known cure, but can usually be effectively treated and controlled. The treatment of celiac disease is strict adherence to a GLUTEN FREE DIET FOR LIFE.

  29. Lactose Intolerance • Lactose intolerance means the body cannot easily digest lactose, a type of natural sugar found in milk and dairy products. Lactose intolerance occurs when the small intestine does not make enough of an enzyme called lactase. • Lactose intolerance most commonly runs in families, and symptoms usually develop during the teen or adult years. • It could be temporary 

  30. SYMPTOMS: • Symptoms of lactose intolerance can be mild to severe, depending on how much lactase the body makes. Symptoms usually begin 30 minutes to 2 hours after eating or drinking milk products. symptoms may include: •Bloating. •Pain or cramps. •Gurgling or rumbling sounds in your belly. •Gas. •Loose stools or diarrhea. •Throwing up.

  31. DIAGNOSIS: • medical history. • To confirm a diagnosis: -Hydrogen breath test -Lactose tolerance test

  32. TREATMENT: • Fortunately, lactose intolerance is relatively easy to treat. No known way exists to increase the amount of lactase enzyme the body can make, but symptoms can be controlled through diet.
