Hepatic and Biliary Disorders

Core Concepts

The liver: a job list worth memorizing

• Synthesis: it makes albumin (which keeps fluid inside blood vessels — low levels cause edema and ascites) and clotting factors (low levels raise bleeding risk).
• Detoxification: it clears ammonia and other waste (failure lets toxins reach the brain, causing confusion — encephalopathy) and metabolizes most drugs, so liver disease changes how medicines work.
• Bile production: bile digests fats and carries bilirubin (the yellow breakdown product of old red blood cells) out of the body. Blocked bile flow causes jaundice (yellow skin and eyes), dark urine, and pale stools.
• Storage: glucose as glycogen, plus vitamins and iron.

Hepatitis: inflammation of the liver

Hepatitis means liver inflammation, from any cause. Viral hepatitis is the classic form:

• Hepatitis A: fecal-oral spread (contaminated food or water); usually acute; vaccine-preventable.
• Hepatitis B: blood and body fluid spread; can become chronic and lead to cirrhosis and liver cancer; vaccine-preventable.
• Hepatitis C: mainly blood spread; frequently chronic; no vaccine, but effective treatments exist.
• Hepatitis D and E: D occurs only with B; E is fecal-oral and especially risky during pregnancy.

Hepatitis can also be caused by alcohol (alcoholic hepatitis), medications and toxins (drug-induced liver injury — acetaminophen overdose is the classic example), autoimmune disease, and metabolic conditions such as nonalcoholic fatty liver disease (NAFLD/NASH). Symptoms — fatigue, nausea, poor appetite, jaundice, dark urine, right-upper-abdominal discomfort — overlap with many illnesses, and some people have none at all, which is why blood testing matters.

Cirrhosis: when scarring replaces the factory

Cirrhosis is the end stage of chronic liver injury: scar tissue replaces functioning liver tissue, so the liver shrinks, hardens, and loses function. Common causes: chronic hepatitis B or C, alcohol-related liver disease, and fatty liver disease. Cirrhosis is compensated (the liver still manages its essential work) or decompensated (complications have appeared). The two core problems are loss of synthetic function (fewer clotting factors, less albumin) and portal hypertension — high pressure in the portal vein carrying blood from the gut to the liver, because scarred tissue resists blood flow.

The complications of cirrhosis

• Ascites: fluid accumulates in the abdominal cavity from portal hypertension plus low albumin. The abdomen swells, breathing and eating become difficult, and the fluid can become infected (spontaneous bacterial peritonitis) — a serious complication.
• Esophageal varices: portal hypertension backs pressure into the veins of the esophagus, which swell like varicose veins. They can rupture and bleed massively — vomiting blood or black stools in a person with cirrhosis is an emergency.
• Hepatic encephalopathy: toxins (classically associated with ammonia) that the failing liver cannot clear reach the brain, causing confusion, sleepiness, personality change, and a flapping hand tremor (asterixis). Worsening confusion in liver disease must never be dismissed as "just being tired."
• Coagulopathy: with fewer clotting factors, the person bruises easily and is at risk of internal bleeding.
• Jaundice accompanies advanced disease, and hepatorenal syndrome (kidney failure triggered by advanced liver disease) is a feared late complication.

Nursing care focuses on assessment (mental status, abdominal girth and weight, bleeding signs, jaundice), safety (fall precautions), skin care (pruritus), fluid balance, and education. Medications are managed carefully because the liver metabolizes many drugs — the pharmacist and provider guide dosing. Scope note: procedures such as paracentesis, endoscopy for varices, and transplant evaluation are provider-driven; institutional protocols vary.

Biliary disorders: gallstones and their complications

Gallstones (cholelithiasis) form when bile components crystallize in the gallbladder. Risk factors include obesity, rapid weight loss, age, pregnancy, and being female. Many gallstones are silent; when one blocks the cystic duct, it causes biliary colic — episodic right-upper-abdominal pain, often after a fatty meal. Cholecystitis is inflammation of the gallbladder, usually from a stone stuck in the duct: constant pain, fever, nausea, and right-upper-abdominal tenderness. Cholangitis is an infection of the bile ducts — fever, jaundice, and abdominal pain together — and is a serious emergency. Gallbladder disease is most often treated surgically; timing and approach follow provider and surgical team decisions.

Nursing assessment and education

Assess systematically: ask about alcohol use and risk factors (without judgment), blood exposures, medications and supplements, and family history; inspect for jaundice (sclera first), bruising, spider-like blood vessels, and abdominal swelling; check mental status; measure weight and girth when ascites is a concern; ask about stool and urine color. Education covers prevention (vaccination, safe practices, alcohol moderation or abstinence, healthy diet for fatty liver), symptom recognition, and medication safety. Use person-first language — say "a person with hepatitis C," never define people by their disease — and avoid stigma.

How It Works / Step-by-Step Process

1. Take the history: alcohol and substance use (asked respectfully), blood exposures, medications and supplements, travel, family history, and symptoms (fatigue, itching, swelling, dark urine, pale stools, bleeding, confusion).
2. Inspect: sclera and skin for jaundice, bruising, spider angiomas, abdominal distention, and leg swelling.
3. Assess function: mental status (orientation, behavior, asterixis), vital signs, weight and abdominal girth (trends matter for ascites), and stool/urine color.
4. Monitor for emergencies: hematemesis, melena, worsening confusion, fever with ascites, and sudden severe abdominal pain warrant immediate provider notification.
5. Protect: fall precautions, bleeding precautions, skin care for pruritus, and fluid balance monitoring per orders.
6. Educate and coordinate: teach prevention (vaccination, safe practices, alcohol and diet), explain treatments, involve dietitian and substance-support services, and prepare the family for follow-up.
