PESHAWAR — Over the last few years, “fatty liver” disease has spread rapidly across Pakistan. This condition emerges when excessive fat accumulates in the liver, an organ that functions as the body’s primary factory. The liver filters blood, stores energy, and helps digest nutrients. However, when fat levels exceed healthy limits, the organ sustains damage, leading to severe health complications.
From NAFLD to MASLD: The New Terminology
Medical professionals previously used the term “Non-Alcoholic Fatty Liver Disease” (NAFLD) because the liver tissues of these patients mirrored those of alcoholics, despite the patients not consuming alcohol. Today, the medical community uses a more precise name: Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD).

This new title highlights the disease’s link to obesity, diabetes, and high blood pressure. In some patients, the condition evolves into a more aggressive form called MASH (Metabolic Dysfunction-Associated Steatohepatitis), where fat causes inflammation and permanent scarring.
The Prevalence in Pakistan
The global rise in diabetes has turned fatty liver into a major health concern. Because diabetes is prevalent in Pakistan, millions of citizens now suffer from this silent ailment. If left unchecked, MASLD can lead to fibrosis (scarring) or cirrhosis. In extreme cases, patients may eventually face liver cancer.

Identifying Potential Symptoms
In its early stages, fatty liver disease management is difficult because MASLD often shows no symptoms. However, as the condition progresses, patients may experience:
- Persistent and severe fatigue.
- Mild pain or discomfort in the upper right side of the abdomen.
- A general sense of being unwell or weak.
If the disease reaches a critical stage, symptoms become more visible. These include swelling in the legs or abdomen, jaundice (yellowing of the skin and eyes), easy bruising, and mental confusion.

Modern Diagnostics and the FIB-4 Score
Doctors diagnose MASLD by assessing risk factors like obesity and checking liver enzyme levels. Modern diagnostic tools have replaced invasive procedures in many cases:
- Imaging: Ultrasound, CT scans, or MRI scans examine the liver’s structure.
- FibroScan: This technology measures “liver stiffness” to estimate the level of scarring.
- FIB-4 Score: This is a simple calculation based on routine blood tests (enzymes and platelets). A score below 1.3 usually indicates a low risk of scarring, while a higher score necessitates a consultation with a liver specialist.
Risk Factors and Prevention
Both adults and children can develop MASLD. High-risk individuals typically struggle with:
- Excessive body weight or obesity.
- Type 2 diabetes and insulin resistance.
- High blood pressure and elevated triglycerides.
- A family history of liver disease.
Treatment: Lifestyle First
There is no single “magic pill” for MASLD. Instead, fatty liver disease management relies primarily on permanent lifestyle changes. Experts recommend a healthy diet rich in fruits and vegetables, at least 150 minutes of weekly exercise, and significant weight loss. Most importantly, patients must maintain strict control over their blood pressure and cholesterol.

FDA-Approved Medications for MASH
While lifestyle is the first line of defense, the US FDA has approved two specific medications for patients with the severe MASH form:
- Rezdiffra (resmetirom): The first drug approved specifically to reduce liver fat and inflammation in adults with moderate to severe fibrosis.
- Wegovy (semaglutide): Originally used for weight loss, this drug is now approved for MASH patients to help improve liver health through weight management.
The Importance of Early Care
Early detection can slow, stop, or even reverse liver damage. For high-risk individuals, regular medical checkups are essential. By adopting positive lifestyle changes today, you can protect your liver and ensure long-term physical health.
