Q

Dumping syndrome

A

Early: 30 mins after eating. Symptoms– abdominal discomfort, N/V, diarrhea, vertigo, dizziness, syncope, diaphoretic, palpitations, tachycardia

Late (1-3 hours after eating): hunger, fatigue, diaphoretic, dizziness, lightheadedness, tachycardia, can cause low blood sugar

Can cause distention bc lots of fluid goes directly into small intestine, antidiarrheal, limit high sugar, small frequent meals

Q

IBS

A

Causes: females, genetics
Dx: symptoms
CM: alternating constipation/diarrhea, LLQ pain
Complications: dehydration, electrolyte disturbances, constipation causing increased hemorrhoids & bowel obstruction
Tx: fiber, anti-diarrhea, probiotics, caffeine alcohol fruit and dairy make it worse

18
Q

Colorectal

A

refers to colon and rectum, which together make up large intestine

19
Q

Colorectal cancer

A

Intermittent painless rectal bleeding most common symptom also Change in Bowel Habits

Other Symptoms: anemia, weak, fatigue, pale, low o2 sats, melena (black tarry stools), Hematochezia (bright red blood in stools)

20
Q

Intestinal obstruction

A

Causes: Paralytic ileus, age, severe constipation, hernia, tumors, scar tissue
Diagnostics: x-ray can show abdominal distention, CAT scans
Clinical Manifestations: Vomiting, pain, reflux, absent bowel sounds, obstipation=no BM, large intestine- abdominal distention, once small intestine and large intestine are full you start vomiting fecal matter. Hyperactive above obstuction and hypoactive bowel sounds below
Complications: rupture –> infection (prognosis is very poor), electrolyte imbalances so lab work is good, peritonitis, necrotic bowel bc not getting blood due to the pressure, death
Interventions: NG tube for continuous suction of gastric secretions and decompression, NPO so you need IV fluids, pain management, may do a bowel resection

21
Q

Small intestine obstruction

A

sporadic, colicky pain
visible peristaltic waves
profuse projective vomitus with fecal odor, which relieves pain

Causes symptoms shortly after onset: abdominal cramps centered around the umbilicus or in the epigastrium, vomiting, and—in patients with complete obstruction—obstipation
With infarction, the abdomen becomes tender and auscultation reveals a silent abdomen or minimal peristalsis. Shock and oliguria are serious signs that indicate either late simple obstruction or strangulation.

22
Q

Large intestine obstruction

A

diffuse and constant pain
significant abdominal distention
infrequent vomiting, leakage of fecal fluid around impaction

Usually causes milder symptoms that develop more gradually than those caused by small-bowel obstruction. Increasing constipation leads to obstipation and abdominal distention.
Lower abdominal cramps unproductive of feces
istended abdomen with loud borborygmi.
There is no tenderness, and the rectum is usually empty. Systemic symptoms are relatively mild, and fluid and electrolyte deficits are uncommon.

23
Q

Volvulus

A

twisting of bowel

24
Q

Intussusception

A

telescoping of bowel

25
Q

Common causes of lower GI bleeding

A

ulcerative colitis, polyps, colon cancer, diverticulosis/diverticulitis, rectal cancer, hemorrhoids

26
Q

Inflammatory intestinal disorders

A 
Appendicitis
Peritonitis
Gastroenteritis
Ulcerative Colitis
Crohn’s Disease
Diverticulitis
27
Q

Inflammatory Bowel Disease

A

A group of immunologically related inflammatory conditions of the colon and small intestine. body mistakes food for foreign objects and sends white blood cells which causes inflammation

Crohn’s disease and ulcerative colitis are major types

Main difference between Crohn’s disease and UC is the location and nature of the inflammatory changes

28
Q

Crohn’s Disease

A

End of small intestine / beginning of large intestine
RLQ pain
20-40 yrs old
Severe diarrhea, crampy abdominal pain, occasional bleeding, fever, fatigue
Food avoidance due to pain –> weight loss

Goal is to rest the bowel, let inflammation subside, prevent infection, give relieve of pain and severe diarrhea

tx: 
Aminosalicylates
Antibiotics 
Steroids 
Immunosuppressant
29
Q

Ulcerative colitis

A

Colon and Rectum
LLQ pain
Bloody loose stools, crampy abdominal pain, urgent bowel (tenesmus), fatigue, anorexia, possible anemia due to blood loss

Complications: hemorrhage, perforation which leads to peritonitis or toxic megacolon (massive dilatation of colon causes gangrene and perforation)
         **Risk for Cancer (10-20X)** 
Tx:
Aminosalicylates
Antibiotics 
Corticosteroids
Immunosuppressant
30
Q

Appendicitis

A

RLQ, rebound tenderness

McBurney’s point

31
Q

Diverticula

A

Out-pouching’s– food gets stuck, causing infection and inflammation (diverticulitis)
Form near the end of the large intestine

Diverticulosis is associated with constipation, low fiber diet and straining with bm -> increases pressure inside colon-> forming diverticulum
Diverticulitis occurs when diverticulum become inflamed -> LLQ pain fever, constipation and decreased appetite

32
Q

Diverticulosis Tx

A

Fiber rich diet

33
Q

Diverticulitis Tx

A

clear liquid diet and oral antibiotics, no fiber at this phase
alternating diarrhea and constipation, chills or fever, LLQ pain
Flagyl, cipro

34
Q

Peritonitis

A

Hallmark signs- abdominal distention, pain & nausea, rebound tenderness, abdominal rigidity (board like)
Tx: Pain increase bp and hr
Bowel sounds may decrease
Want to decompress stomach and bowel using ng tube, give fluids, antibiotics, pain meds, supplemental electrolytes, monitor bowel sounds

35
Q

Acute hepatitis

A

N/V/D, Anorexia, Fever, Light (clay) colored stools, Dark urine, Jaundice

Tx:
A – no specific drug therapy, wait for liver to heal itself
B – a-Interferon, Ribavirin
C – Pegasys

Prevention
A – Hepatitis A vaccine, immune globulin
B – HBV (series of 3)
C – no vaccine available

Nutritional Therapy
Important for hepatocyte regeneration
Sufficient calories to prevent weight loss
Vitamin Supplements

36
Q

Cholecystitis

A

RUQ pain (gallbladder is below liver)
Murphy’s sign
Increased pain with deep breath
N/V, Feeling full, abdominal distention, jaundice, fever
ESWL- break up stones so it can travel easier
Acute episode focus on: Pain control, antibiotics, fluids and electrolytes
Tx: Anticholinergics, Analgesics, Fat-soluble vitamins, Bile salts, Cholestyramine (Questran)

37
Q

Albumin

A

3.5-5.0 g/dl

38
Q

Pre-Albumin

A

20 mg/dl

39
Q

Transferrin

A

215-380mg/dl or 2.15-3.8g/L

40
Q

Ammonia

A

15-110 mg/dL

41
Q

Phosphorus, Potassium, Albumin

A

all about 3.5-5

42
Q
