Children can also suffer from liver diseases, such as congenital metabolic disorders or viral hepatitis, with symptoms often subtle. Parents should watch for changes in appetite, jaundice, or fatigue, and arrange regular health check ups. Pregnant women face a heavier liver burden as they metabolize more hormones and nutrients. If conditions like hepatitis or fatty liver are present, both mother and baby may be affected. During pregnancy, avoiding alcohol, maintaining a balanced diet, and checking liver function regularly are essential for safety.

Liver fibrosis is the liver’s repair response after damage, but if it worsens it can progress to cirrhosis. Cirrhosis is the end stage of many liver diseases, where the liver gradually loses function and may cause ascites, jaundice, or even develop into liver cancer. Liver cancer often arises from chronic hepatitis or cirrhosis, with early symptoms being subtle, so regular screening is the only effective defense. People should monitor their condition through liver elasticity scans or blood tests, and treat underlying issues such as fatty liver or hepatitis early. High risk groups, such as hepatitis B carriers, are advised to undergo ultrasound or alpha fetoprotein tests every six months to reduce risk.

Viral hepatitis, such as types A, B, and C, is also a major factor damaging the liver. It is caused by different viruses, some preventable through vaccines. Good hygiene, avoiding shared needles, and practicing safe behaviors are key to lowering infection risk. Drug induced liver injury is another concern: certain medications or supplements, if taken long term or in excess, can burden the liver. People should avoid self medicating and consult professionals before using herbal remedies or supplements to safeguard liver health.

Fatty liver is the most widespread, often caused by obesity, poor diet, or lack of exercise. Early symptoms are subtle, but long term progression can lead to fibrosis or cirrhosis. Alcoholic liver disease results from excessive drinking, as toxic byproducts of alcohol metabolism accelerate liver cell damage. To prevent these conditions, people should maintain a balanced diet, reduce oil and sugar intake, exercise regularly, and control alcohol consumption—or even quit drinking.

Common ones include the “three highs”—high blood pressure, high blood sugar, and high cholesterol—which raise the risk of fatty liver and cirrhosis. In addition, chronic inflammation continuously stimulates the liver, leading to fibrosis. To protect the liver, people should maintain healthy habits, avoid excessive stress, poor diet, and lack of exercise, and actively control the three highs. Doing so not only safeguards cardiovascular health but also preserves liver function.

Because the liver itself has no pain nerves, early problems usually show no symptoms. Only when the liver enlarges and presses on surrounding tissues might discomfort occur. Therefore, people cannot rely on feelings to judge liver health. Regular check ups, including blood tests, ultrasound, or fibrosis scans, are essential to detect abnormalities early. Early diagnosis greatly improves treatment outcomes and prevents disease progression.
