    Study Notes

    Liver Disease Overview

    • Liver is the largest internal organ in the body, located below the diaphragm in the right upper abdominal quadrant.
    • It's the largest gland, producing bile essential for fat digestion.
    • Bile is stored in the gallbladder.
    • The liver can regenerate itself from as little as 25% of its original size.
    • Liver's functions include filtering and cleansing the blood, creating and breaking down sugar, proteins, and fats.

    Liver Functions

    • Filters and cleans the blood.
    • Breaks down sugar, proteins, and fats.
    • Stores vitamins A, D, E, K, and B12.
    • Produces bile to aid fat digestion and absorption of fat-soluble vitamins.
    • Stores minerals, like iron and copper.
    • Removes metabolic products and toxins from the blood.
    • Fights infections by capturing and digesting bacteria, fungi, parasites, and cellular debris.
    • Produces essential proteins and hormones, including blood-clotting factors, albumin, transporter proteins, and thrombopoietin.
    • Regulates glucose and cholesterol levels.
    • Breaks down haemoglobin, cholesterol, protein, sex-steroids, and many drugs.

    GDC Learning Outcomes

    • Explain general and systemic diseases and their relevance to oral health.
    • Describe relevant and appropriate physiology and its application to patient management.
    • Describe the properties of relevant medicines and therapeutic agents and their application to patient management.

    Liver Disease and the Hygienist/Therapist

    • Understand liver disease's functions.
    • Know how a diseased liver affects the body.
    • Recognize the symptoms of liver disease.
    • Understand how a dental treatment plan needs modification due to liver disease.

    Causes of Liver Damage

    • Alcohol
    • Viral infections (Hepatitis A-E)
    • Non-alcoholic fatty liver disease
    • Body's immune system (e.g., primary biliary cirrhosis)
    • Tumours (e.g., liver cancer)
    • Cysts
    • Haemochromatosis
    • The liver filters alcohol, breaking it down and removing it from the body.
    • Liver cells die during this process.
    • The liver needs time to regenerate and make new cells.
    • Prolonged excessive alcohol intake hinders liver recovery.
    • Can lead to serious and permanent damage.
    • Alcoholic fatty liver disease (usually no symptoms, reversible)
    • Alcoholic hepatitis (inflammation of the liver; reversible early on)
    • Cirrhosis (scarring of the liver; irreversible and prevents normal function).

    Symptoms of Cirrhosis

    • Often no symptoms until severe damage.
    • Tiredness, weakness, nausea, and loss of appetite.
    • Weight loss, palmar erythema, spider naevi, finger clubbing, and sialosis.
    • Jaundice, itchy skin, dark urine, and tarry stools.
    • Bleeding or bruising easily.
    • Loss of libido.
    • Swollen legs or abdomen (ascites).
    • Gynaecomastia or testicular atrophy, oesophageal varices and encephalopathy
    • Liver cancer

    Treatment of Cirrhosis

    • No cure to deal with symptoms and complications of cirrhosis.
    • Stop drinking alcohol completely
    • Healthy diet to address malnutrition, low protein and low salt diet, loss of weight and stop smoking.
    • Medications (diuretics, beta-blockers, skin creams)
    • Liver transplant.

    Non-Alcoholic Fatty Liver Disease (NAFLD)

    • Build-up of fat in the liver (not caused by alcohol).
    • Usually related to obesity.
    • Four stages, often symptom-free in the early stages.
    • Inflammation, fibrosis, cirrhosis can occur.
    • Symptoms of fibrosis: abdominal pain, tiredness, weight loss, weakness
    • Symptoms of cirrhosis (see above).

    Treatment of NAFLD

    • Healthy lifestyle changes (lose weight, healthy diet, exercise, stop smoking and alcohol).
    • Treat complications (diabetes, high cholesterol, hypertension).
    • Liver transplant if cirrhosis develops.

    Other Causes of Liver Damage

    • Primary biliary cirrhosis (immune system attacks bile ducts)

    • Tumors/cysts (Primary liver cancer, secondary liver cancer, liver cysts)

    • Haemochromatosis (inherited iron overload damages liver, joints, pancreas and heart).

    Key Takeaways:

    • Liver is a vital organ with multiple functions.
    • Various factors can damage the liver, including alcohol, viruses, and autoimmune issues.
    • Liver damage can progress through different stages (fatty liver, hepatitis, cirrhosis) leading to serious long-term complications.
    • Treatment usually focuses on addressing the underlying cause, modifying lifestyle choices and managing symptoms.
