The liver is a vital organ, responsible for detoxifying waste, metabolizing nutrients and regulating hormones. Yet global liver health is alarming: the World Health Organization (WHO) reports non-alcoholic fatty liver disease (NAFLD) affects over 1 billion people, while chronic hepatitis B and C infect 325 million, causing 1.3 million annual deaths from cirrhosis or liver cancer. Common conditions like NAFLD (linked to obesity) and alcoholic liver disease also contribute to rising mortality.​

Valid liver health detection methods are evidence-based: Blood tests measuring ALT, AST and bilirubin assess basic function. For high-risk groups (e.g., those with obesity or family liver disease history), annual blood tests plus biennial ultrasound are advised to spot issues early. Abdominal ultrasound or CT scans detect fatty buildup or tumors and liver biopsy (when needed) is the gold standard for diagnosing cirrhosis or inflammation. These tools enable early intervention for treatable conditions.​

In contrast, unproven methods like "liver detox" programs, often involving fasting, herbal supplements (e.g., green tea extract) or coffee enemas, are useless and dangerous. Research shows 20% of drug-induced liver injuries stem from herbal supplements; for instance, some milk thistle products, falsely promoted as liver protectors, have caused rare but serious liver inflammation. Coffee enemas risk infections or fatal electrolyte imbalances, while fasting worsens existing liver damage (e.g., in hepatitis B patients).​

In summary, protecting liver health relies on proper detection: regular screenings for high-risk groups such as heavy drinkers and diabetics, and avoidance of unproven detox methods. Pairing early detection with lifestyle changes - including limiting alcohol intake, maintaining a balanced diet and engaging in regular exercise to prevent further liver damage. Remember: effective liver care depends on science, not unproven remedies.
