Liver disease is often referred to as “silent threat” because it can progress for years with few or no noticeable symptoms. Understanding the stages, from early fatty liver changes to advanced cirrhosis, can help you protect your health and know when to seek care.
The Stages of Liver Damage
• Stage 1: NAFLD (Non-Alcoholic Fatty Liver Disease)
Fat begins to accumulate in liver cells, usually linked to obesity, diabetes, or high cholesterol. In Singapore, NAFLD is increasingly common due to rising rates of metabolic syndrome. This stage can progress without causing any symptoms, which is why regular health screenings are important. Lifestyle changes like eating a balanced diet and staying active can often reverse NAFLD at this point.
• Stage 2: NASH (Non-Alcoholic Steatohepatitis)
When fat buildup leads to inflammation, the liver can start to sustain damage. NASH is more serious because it can progress silently over time. This stage may cause mild symptoms, such as fatigue or abdominal discomfort, but they are often overlooked. Medical evaluation can detect inflammation early through blood tests or imaging, helping prevent progression.
• Stage 3: Fibrosis
Healthy liver tissue is gradually replaced by scar tissue. Although liver function may still be adequate at this point, damage is happening at a cellular level. Early fibrosis can still be managed if detected early. Timely treatment may slow or stop further scarring. Monitoring liver health through periodic checkups is essential for those with risk factors.
• Stage 4: Cirrhosis
Significant scarring causes the liver to harden and lose its ability to function properly. Symptoms like jaundice, swelling in the abdomen, easy bruising, and persistent fatigue can appear. At this advanced stage, complications like ascites, variceal bleeding, or liver failure may occur. Prompt medical attention and specialist care can help manage symptoms and prevent further decline.
Why Early Detection Matters
Liver disease often worsens quietly before symptoms are noticeable. Detecting issues in the early stages allows for interventions like diet adjustments, weight management, and medical treatment that can slow or even reverse damage.
Taking Care of Your Liver
• Eat a balanced diet with plenty of fibre, whole grains, fruits, and vegetables.
• Stay physically active to maintain a healthy weight and reduce fatty liver risk.
• Limit alcohol consumption, as excessive intake is a major contributor to liver damage.
• Get vaccinated for hepatitis A and B to protect against viral liver infections.
• Avoid overusing painkillers or supplements that can stress the liver.
• Stay hydrated to help your liver flush out toxins efficiently.
• Go for regular health checkups and liver function tests, especially if you have diabetes, high cholesterol, or a family history of liver disease.
When to Seek Medical Attention
If you notice yellowing of the eyes, itchy skin, dark urine, or unexplained fatigue, it’s important to seek medical attention promptly. Persistent symptoms, abnormal liver function tests, or a family history of liver disease should also prompt evaluation by a gastroenterologist. Specialists like Dr Fernandes Mark Lee manage liver disease across all stages and can guide patients through diagnosis and treatment options.
Protecting Your Long-Term Health
Understanding the stages of liver damage empowers you to take action early. Regular checkups, lifestyle changes, and timely medical care can prevent complications like cirrhosis. Patients with liver issues should consult gastroenterologists such as Dr Fernandes Mark Lee or visit trusted local healthcare resources for reliable information.
