gastrointestinal diseases Flashcards
what is IBS?
what plays a role?
symptoms?
1st rule?
- intestinal problem that doesnt have a clear cause
- abnormal contractions in the intestine, food intolerance, stress
- abdominal pain or cramps, bloating, doarrhea, constipation, gassiness
- check wwith a doctor, there may be sign of other serious disease or disorder
nutritional care in IBS
- Eat small, frequent meals. Chew very
well to help digestion. - Eat slowly = No air
swallowing = dec gassy feeling - Eat plenty of fibers to prevent
constipation - Avoid foods that irritate or cause too
much gas - Limit substances that make symptoms
worse: caffeine, alcohol, fat, sugar
alcohol, fructose etc. - Drink more fluids to prevent
constipation - manage stress and anxiety
- reduce lactose if lactose intolerant
- antacids may make symptoms worse = talk to doctor if already prescribed and pay attention to some supplements
definition of constipation
characteristics
difficult or infrequent passage of stool
- difficult: physical discomfort of straining, hard stools, or incomplete evacuation
- infrequent: less stool every 3 days and / or hard stool
- chronic medications, dysmobility disorders, lifestyle: inadequate fiber intake, laxative abuse, physical inactivity, ignoring urge to defecate
nutritional care in constipation
- increase fiber rich foods: cooked mloukhiye, fruits with the skin, bran containing cereals, whole wheat bread, legumes, cooked spinach
- 8 cups of water /day
- never delay going to the bathroom
-increase physical activity = maintains muscle tone of GI tract
limit caffeine containing beverages
diarrhea:
Frequent evacuation of liquid stools,
usually exceeding 300 mL + an excessive
loss of fluid and electrolytes, especially
sodium and potassium
causes of diarrhea
- inlammatory diseases
- medications
- viral, fungal, or bacterial infections
- overconsumption of sugars or other osmotic substances
- insufficient or damaged mucosal absorptive surface
first step in nutritional care in diarrhea
replace all necessary fluids and electrolytes from ORS, soups and broths, vegetable juice, isotonic fluids
avoid lactose, fructose, sugar alcohols, large amount of sucrose may worsen osmotic diarrhea
- modest intake of prebiotic components and soluble fibers (pectins, gums) slows transit thru GI
how do soluble fibers help in diarrhea?
soluble fibers fermented in the colon by bacterias = production of short chain fatty acids
–> substrates for colon cells –> facilitate absorption of fluid and salts, help regulate GI motility
what is also useful in diarrhea management
micronutrient replacement, it accelerates the normal regeneration of the damaged mucosal cells.
what are prebiotics
nondigestible substnces in food that promote the growth of normal healthy bacteria already in the colon.
sources: dietary fibers, starch, sugar alcohols
probiotics
Probiotics: are active
cultures, such as some
strains of lactic acid
bacteria, or foods rhat
contain them, that help
reintroduce or change
bacteria in the
intestine.
i.e: Lactobacilli and
bifidobacteria in yogurt.
how do probiotic cultures help
- decrease the risk of some cancers
- shorten duration of diarrhea
- decrease symptoms of lactose intolerance
- prevent allergy symptoms
- decrease IBS symptoms
what is heartburn?
main symptom of reflux
what happens in reflux disease?
stomach contents flow backward to the esophagus –> feeling pain like ulcer, heartburn, trouble swallowing, regurgitating stomach acid.
what are the factors associated with acid reflux?
- pregnancy
- hiatal hernia
- abdominal pressure from obesity
