Your liver runs over 500 functions in your body β and about 9 in 10 liver conditions are considered preventable. Here's what raises your risk, what to watch for, and what actually helps.
Your liver is the body's largest internal organ and its main processing plant β everything you eat, drink, or absorb passes through it.
Processes everything you eat, drink, breathe, and absorb β removing toxins, drugs, and waste from your bloodstream.
Creates bile to break down fats and absorb vitamins A, D, E, and K β essential for digestion.
Converts excess glucose into glycogen, then releases it when your body needs energy between meals.
Produces albumin and clotting factors that keep fluid in your bloodstream and help wounds heal.
Creates cholesterol and carrier proteins, balancing HDL and LDL levels in your body.
Metabolizes most drugs you take β a big reason liver health affects how medicines work in your body.
Some risks are lifestyle-driven and modifiable; others are genetic or viral. Knowing yours helps you decide when to get tested.
Regular heavy drinking is a leading cause of liver disease. Even moderate drinking adds strain over time.
Metabolic dysfunction-associated steatotic liver disease (MASLD) affects roughly 1 in 4 adults globally and is often silent until advanced.
Hepatitis B and C are major causes of cirrhosis and liver cancer. Vaccines exist for Hepatitis A and B.
Genetic conditions like hemochromatosis or Wilson's disease raise risk β know your family health history.
Long-term use of some painkillers, antibiotics, and herbal supplements can affect the liver.
150 minutes of moderate exercise weekly is linked to notably lower fatty-liver risk. Movement is medicine.
Liver disease is often called "silent" because symptoms appear late. Seek medical evaluation if you notice these signs.
Jaundice occurs when bilirubin builds up β one of the most recognizable signs of liver distress.
Fluid build-up (ascites) in the abdomen can signal cirrhosis or advanced liver disease.
Persistent tiredness that sleep doesn't fix β the liver's struggle to process toxins can drain your energy.
Tea-colored urine and clay-colored stools suggest bilirubin isn't being processed properly.
Bile salt build-up under the skin can cause persistent itching, especially on hands and feet.
The liver produces clotting factors β when damaged, you may bruise easily or bleed longer from cuts.
Food is one of the most powerful levers for liver health, especially for MASLD (fatty liver).
Spinach, kale, and arugula are rich in glutathione β an antioxidant that supports the liver's detox pathways.
Broccoli, cauliflower, and Brussels sprouts support the liver's natural detox enzyme activity.
Salmon, mackerel, and sardines provide omega-3s that can help reduce liver fat and inflammation.
Walnuts and flaxseeds bring antioxidants and healthy fats that support liver enzyme activity.
Fructose is metabolized almost exclusively by the liver β excess sugar is a key driver of fatty liver.
Trans fats, preservatives, and high sodium make the liver work harder. Cook fresh meals where you can.
Even without weight loss, exercise directly reduces liver fat. Aim for a mix of these three types.
Brisk walking, cycling, or swimming for 30 min, 5 days a week β the most consistently effective type for burning liver fat.
Bodyweight or weights 2β3x weekly. Builds muscle mass, which improves insulin sensitivity and liver metabolism.
Short bursts of intense activity β 15β20 min sessions, 2x weekly, are linked to meaningful drops in liver fat markers.
Follow this decision guide. When in doubt, book the appointment.
Do you have any warning signs (jaundice, abdominal swelling, dark urine, easy bruising)?
Are you overweight, diabetic, or do you drink alcohol regularly?
Has it been more than 12 months since your last liver function blood test?
Common misconceptions about liver health β and what the evidence actually says.
Your liver detoxifies your body continuously on its own. There's no solid evidence that juice cleanses, detox teas, or liver flushes improve liver function β and some herbal "detox" products have actually been linked to liver injury.
Multiple large studies associate 2β3 cups of coffee a day with lower rates of fibrosis, cirrhosis, and liver cancer, even in people with existing liver disease β both caffeinated and decaf appear to help.
MASLD (fatty liver linked to metabolic health) is now the most common liver condition worldwide, including in people who drink little or no alcohol. Obesity, diabetes, and metabolic syndrome are major drivers.
Fatty liver and even early fibrosis can improve with weight loss, diet changes, and exercise. The liver can regenerate β but usually only if the underlying cause is addressed before cirrhosis sets in.
Herbal products like kava, comfrey, and high-dose green tea extract have been associated with liver injury. "Natural" doesn't automatically mean "safe," especially at high doses or combined with medication.
Research consistently links modest weight loss β just 5β10% of body weight β to reduced liver fat, less inflammation, and even fibrosis improvement in people with MASLD.
A snapshot of recent, peer-reviewed developments in liver science. This is a research summary for awareness only, not a treatment recommendation β talk to your doctor about what applies to you.
International experts introduced "metabolic dysfunction-associated steatotic liver disease" (MASLD) to better reflect the metabolic roots of the condition. Diagnosis now centers on steatosis plus at least one metabolic risk factor β such as type 2 diabetes, obesity, or high cholesterol β regardless of alcohol intake, which has broadened how the condition is studied and treated.
Researchers identified a microRNA (miR-93) that drives MASLD progression, and found that vitamin B3 (niacin) β an inexpensive, already-approved supplement β may help suppress it. It's early-stage research, not a proven treatment, but it points to a low-cost avenue worth watching.
Scientists identified a compound (ION224) designed to block a pathway involved in metabolic dysfunctionβassociated steatohepatitis (MASH), the more aggressive form of fatty liver disease that can progress to cirrhosis and liver cancer. It's in earlier-stage development, alongside other emerging MASLD/MASH drug candidates.
An international team found altered expression of specific genes tied to liver fibrosis in people with obesity and MASLD, offering a possible new target for predicting or slowing disease progression. The team is now studying whether the link is causal.
Updated clinical guidance increasingly favors non-invasive scoring tools β FIB-4, the ELF blood test, and elastography-based liver stiffness scans β over biopsy for staging fatty liver disease in most patients, making risk assessment more accessible.
These supplement categories are commonly TGA-listed in Australia for liver support. Always consult your doctor before starting any supplement.
The most studied herbal supplement for liver support. TGA-registered products are typically standardised to 80% silymarin, often used for antioxidant and anti-inflammatory support.
A precursor to glutathione, the liver's master antioxidant. TGA-registered NAC supports the body's natural detoxification pathways.
High-quality TGA-registered vitamin E is sometimes used for MASLD/MASH under medical supervision.
High-EPA/DHA omega-3s may help reduce liver fat and inflammation markers in people with MASLD.
