Study Notes

Liver Disease

Liver disease is highly prevalent; affecting 3 in 10 Australians.
Prevention and health promotion are crucial.
Liver cirrhosis is a leading risk factor for hepatocellular carcinoma.
Common causes include: excessive alcohol consumption, smoking, a fatty diet, chronic infection, and tissue injury.
Medications associated with liver injury include analgesics, antiepileptics, and antimicrobials.

Hepatitis

Hepatitis refers to liver inflammation.
It can be acute or chronic.
There are five types: Hepatitis A, B, C, D, and E, each with distinct transmission routes and symptom severity.

Treatment for Hepatitis

Treatments include a well-balanced diet, vitamin supplements, and rest (amount varies depending on the severity).
It's essential to avoid alcohol and medications metabolized by the liver.
Notifying potential contacts about the infection is vital.
Medications may be prescribed.

Early Screening for Liver Issues

Liver biochemistry and liver function tests (LFTs) are crucial for early detection of potential liver issues.
Elevated bilirubin levels during liver function investigations could indicate a range of liver problems.

Gallbladder

The gallbladder is susceptible to several conditions, including cholelithiasis (gallstones), cholecystitis (gallbladder inflammation), and cancer.
Understanding the pathophysiology and nursing management of cholecystitis is crucial for providing effective care.

Pancreatitis

Pancreatitis is a condition that affects the pancreas.
It can be acute, chronic, or even lead to cancer.
The pathogenic process of acute pancreatitis involves the activation of digestive enzymes within the pancreas, leading to tissue damage and inflammation.

Lower Gastrointestinal Conditions

Intestines Role: Responsible for digestion and absorption of nutrients.
Clinical Manifestations of Intestinal Abnormalities: Abdominal pain, diarrhea, constipation, bloating, nausea, vomiting, and weight loss.
Causes of Chronic Abdominal Pain: Irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), coeliac disease, diverticular disease, and bowel cancer.

Irritable Bowel Syndrome (IBS) vs Inflammatory Bowel Disease (IBD)

IBS: Characterized by abdominal pain, bloating, diarrhea, and constipation. No inflammation in the gut.
IBD: Chronic inflammatory condition affecting the GI tract. Includes conditions like ulcerative colitis and Crohn's disease.

Coeliac Disease

An autoimmune disorder triggered by gluten ingestion.
Damages the small intestine, leading to malabsorption of nutrients.

Bowel Cancer in Australia

Fourth most common cancer.
Second leading cause of cancer death.
Early diagnosis: Improves survival rates.

Risk Factors for Bowel Cancer

Age (over 50)
Family history of bowel cancer.
Personal history of polyps or IBD.
Smoking and excessive alcohol consumption.
Diet low in fiber and high in red meat.
Obesity and lack of physical activity.

Clinical Manifestations of Bowel Cancer

Changes in bowel habits.
Blood in stool (rectal bleeding).
Abdominal pain, bloating, and fatigue.
Unexplained weight loss.

Investigations for Bowel Cancer

Colonoscopy: Visual examination of the colon.
Sigmoidoscopy: Visual examination of the sigmoid colon.
Faecal occult blood test (FOBT): Detects blood in the stool.

Diverticular Disease

Formation of pouches (diverticula) in the wall of the colon.
Can lead to diverticulitis (inflammation of the diverticula).

Polyps

Abnormal growths on the lining of the colon.
Some polyps can be precancerous.

Colonoscopy

Procedure: Examination of the colon using a flexible tube with a camera.
Indications: Screening for colorectal cancer, diagnosis of other colon conditions, and removal of polyps.
Preparation: Fasting and bowel cleansing.
During procedure: Sedation is usually provided.
Recovery: Most patients recover within a few hours.

Diagnostic Tests

Barium Enema: X-ray examination of the colon after administration of barium contrast.
Faecal Occult Blood Test: Detects microscopic blood in stool.
Sigmoidoscopy: Visual examination of the sigmoid colon with a flexible tube.

Lifestyle and Nutritional Changes for Lower GIT Disorders

High-fiber diet: Promotes regular bowel movements and reduces constipation.
Low-fat diet: May reduce symptoms of diarrhea and bloating.
Avoidance of trigger foods: Identify and avoid foods that worsen symptoms (e.g., spicy foods, dairy).
Regular exercise: Promotes bowel function.
Stress management techniques: Stress can exacerbate gastrointestinal symptoms.

Impact of Gastrointestinal Surgery

Potential for complications: Infections, bleeding, and bowel obstruction.
Changes in diet and bowel habits: May require dietary modifications or the use of medication.
Quality of life: Can be affected by symptoms, side effects of surgery, and lifestyle changes.
