What is fatty liver disease and how is it treated?
Fatty liver disease occurs when excess fat accumulates in liver cells, impairing liver function. It ranges from simple fat accumulation to inflammation and scarring. Treatment focuses on lifestyle changes — weight loss, dietary modification, and managing underlying conditions such as diabetes or high cholesterol. S.L. Raheja Hospital in Mumbai provides specialised Gastro-Intestinal Science care for patients with fatty liver disease at all stages.
Tip: Fatty liver disease is often silent in early stages. Routine blood tests and ultrasound can detect it before symptoms appear.
There are two main types of fatty liver disease:
- Non-Alcoholic Fatty Liver Disease (NAFLD) — fat build-up unrelated to alcohol consumption; the most common form globally.
- Alcoholic Fatty Liver Disease (AFLD) — caused by excessive alcohol intake.
- Non-Alcoholic Steatohepatitis (NASH) — a more severe form of NAFLD involving liver inflammation and cell damage.
What are the most common causes of fatty liver?
Fatty liver disease develops when the liver cannot process and break down fats efficiently, causing fat to accumulate in liver cells. The following are the most frequently identified causes:
- Obesity or being overweight
- Type 2 diabetes and insulin resistance
- High levels of triglycerides or LDL cholesterol in the blood
- Excessive alcohol consumption (for AFLD)
- Rapid weight loss or malnutrition
- Certain medications, including corticosteroids and some chemotherapy drugs
- Metabolic syndrome
- Polycystic ovary syndrome (PCOS)
- Underactive thyroid (hypothyroidism)
In Mumbai, rising rates of sedentary lifestyles, processed food consumption, and type 2 diabetes contribute to a growing prevalence of NAFLD symptoms in the population. Patients with diabetes or metabolic conditions are at particularly elevated risk.
What are the 5 signs of a fatty liver and symptoms of liver inflammation?
Fatty liver disease is frequently asymptomatic in its early stages. When symptoms do appear, they may indicate progression to inflammation (steatohepatitis) or fibrosis. Common signs include:
- Persistent fatigue and low energy
- Dull or aching discomfort in the upper right abdomen
- Unexplained weight loss
- Weakness and general malaise
- Enlarged liver (hepatomegaly), detected on examination or imaging
Symptoms of liver inflammation in adults — which may indicate NASH or advanced fibrosis — include:
- Nausea and loss of appetite
- Abdominal swelling (ascites) in advanced cases
- Yellowing of the skin or eyes (jaundice) — typically appearing in later stages of liver disease
- Spider-like blood vessels visible on the skin
- Confusion or difficulty concentrating (hepatic encephalopathy, in severe cases)
Warning: Jaundice, abdominal swelling, or confusion alongside known liver disease require urgent medical assessment. Do not delay — use the booking form on this page to arrange an appointment promptly.
What are the stages of fatty liver disease and how are they identified on ultrasound?
Fatty liver disease progresses through distinct stages. Early identification — often through ultrasound or blood tests — is key to preventing irreversible damage.
| Stage | Name | What Happens | Reversible? |
|---|---|---|---|
| Stage 1 | Simple Steatosis | Fat accumulates in liver cells; no inflammation | Yes, with lifestyle changes |
| Stage 2 | Steatohepatitis (NASH) | Fat plus liver inflammation and cell damage | Partially, with treatment |
| Stage 3 | Fibrosis | Scar tissue forms around liver cells | Partially, with early intervention |
| Stage 4 | Cirrhosis | Extensive scarring; liver function severely impaired | Not reversible; manageable |
On ultrasound, fatty liver is graded by the degree of increased echogenicity (brightness) of the liver compared to the kidneys. Grades I, II, and III correspond broadly to mild, moderate, and severe fat infiltration. A gastroenterologist may also order a FibroScan (transient elastography) to assess liver stiffness and estimate the degree of fatty liver fibrosis non-invasively.
What is a healthy diet for the liver and how can fatty liver be reduced?
There is currently no approved medication specifically for NAFLD or NASH. The cornerstone of fatty liver treatment is lifestyle modification. A structured approach can significantly reduce liver fat and, in early stages, reverse the condition.
Dietary recommendations for a healthy liver:
- Increase intake of vegetables, fruits, whole grains, and legumes
- Choose lean proteins — fish, poultry, tofu, and pulses
- Include healthy fats from sources such as olive oil, nuts, and avocado
- Limit refined carbohydrates, white bread, white rice, and sugary beverages
- Avoid processed and ultra-processed foods high in saturated fat
- Eliminate or strictly limit alcohol consumption
- Reduce added sugar, including fruit juices and sweetened drinks
Foods to avoid with fatty liver:
- Alcohol (in any quantity for NASH or fibrosis)
- Sugary soft drinks and packaged fruit juices
- Fried and fast foods
- Red and processed meats in excess
- High-fructose corn syrup products
Other treatment strategies:
- Gradual, sustained weight loss of 7–10% of body weight (rapid weight loss can worsen liver inflammation)
- Regular aerobic exercise — at least 150 minutes per week of moderate-intensity activity
- Optimal management of diabetes, hypertension, and dyslipidaemia through the endocrinology team where relevant
- Avoidance of hepatotoxic medications unless medically necessary
- Regular monitoring with liver function tests and imaging
Tip: Even a 5% reduction in body weight has been shown in clinical literature to reduce liver fat. Consistent small changes outperform crash diets.
When should you see a gastroenterologist for fatty liver disease?
Many people with fatty liver disease are diagnosed incidentally during routine health checks. However, prompt specialist review is warranted in the following situations:
- Persistent fatigue or upper right abdominal discomfort lasting more than 2 weeks
- Liver function tests (LFTs) that are elevated on two or more consecutive blood tests
- Ultrasound report indicating moderate or severe fatty liver (Grade II or III)
- Known risk factors — obesity, type 2 diabetes, or metabolic syndrome — combined with any new abdominal symptom
- Unexplained weight loss alongside abdominal symptoms
- Any appearance of jaundice, abdominal swelling, or confusion
- A family history of liver cirrhosis or liver cancer
Do not wait for symptoms to worsen before seeking evaluation. Early-stage fatty liver disease is manageable and, in many cases, reversible with appropriate guidance from a gastroenterologist.
How does S.L. Raheja Hospital in Mumbai approach fatty liver disease care?
S.L. Raheja Hospital in Mumbai, located at Mahim West, offers a structured pathway for patients with fatty liver disease through its Gastro-Intestinal Science department. The team provides diagnostic evaluation including liver function tests, abdominal ultrasound, and FibroScan assessment, alongside personalised management plans addressing diet, weight, and co-existing metabolic conditions.
Where fatty liver disease co-exists with diabetes or hormonal disorders, the GI team works alongside the endocrinology specialists to coordinate care. Patients with advanced fibrosis or cirrhosis are assessed for further hepatological intervention as clinically indicated.
