Q

Alternative Route

A

Overflow can back into the spleen and stomach. It can also go to the esophagus. The esophagus becomes dilated, makes the veins weak, causes rupture, leads to bleeding.

56
Q

Important Things About IBS

A

Chronic Functional Disease.
Anxiety, Depression, Abuse, PTSD.
Antidepressants can help.
Back and forth between diarrhea and constipation.
Excessive flatulence!
Low FODMAP (sugar) diet, no gas-producing foods, increase fiber intake (20 g daily), yogurt better than milk, and probiotics.

57
Q

Important Things About C-Diff

A

Gram Positive Spore Forming & Toxin Producing Bacillus.
Watery diarrhea with mucus.
Antibiotics kill off natural flora and can lead to c-diff bacteria overgrowth.
PPI Use increases risk for c-diff because it decreases acidity in the stomach which allows the bacteria entered orally to not be broken down by acid.
Inflammation opens you up for more infections.
Enteric Isolation.
Stool sample.
Disposable oral thermometer vs. Dynamap.
Can be given IV or per enema.
Fecal Transplant Microbiota.
Vancomycin

58
Q

Management of Colorectal Cancer

A

Surgery most common.
May be chemotherapy and radiation.

59
Q

Hernia Strangulation

A

Medical emergency! Blood supply is unable to reach the hernia. Can cause bowel ischemia.

60
Q

Causes of a Hernia

A

Congenital, previous abdominal surgeries, muscle weakness, heavy lifting, straining with constipation, and pregnancy.

61
Q

Reducible vs. Incarcerated

A

Hernias are classified as reducible when the hernia contents can be placed intra-abdominally through the layers of the abdominal wall. If the contents of the hernia cannot be reduced, the hernia is considered incarcerated.

62
Q

Crohn’s Disease Complications

A

Nutritional problems, especially when the terminal ileum is involved.
Fat malabsorption and anemia occur.
Small intestinal cancer.

63
Q

Causes of Inflammatory Bowel Disease

Labs
CBC
Serum electrolyte levels
Serum protein levels

67
Q

Nutritional Therapy of Inflammatory Bowel Disease

Lactose
High-fat foods
Cold foods
