MASH: Specialist Metabolic Liver Care
MASH (formerly known as NASH) is an advanced form of fatty liver disease where excess fat causes inflammation and damage to your liver cells.
As a specialist in fatty liver disease (MASLD/MASH), Dr Nadir Abbas provides expert, multidisciplinary care in Birmingham to halt inflammation and prevent permanent liver scarring.
What is Metabolic Dysfunction-Associated Steatohepatitis (MASH)?
Metabolic Dysfunction-Associated Steatohepatitis (MASH) is a condition in which a buildup of fat in the liver leads to severe inflammation and cell damage. It is the more serious progression of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD).
If left untreated, the continuous inflammation caused by MASH leads to deep liver scars (fibrosis) and eventually cirrhosis. MASH is closely linked to metabolic conditions such as type 2 diabetes, high blood pressure, and carrying extra weight around the waist.
At House of Health, Dr Abbas works alongside a multidisciplinary team to address not just your liver, but your complete metabolic health.
As Seen On
Stages of MASH
Fatty liver disease progresses gradually. Dr Nadir uses state-of-the-art, non-invasive tests to see exactly how your liver is doing:
Early Stage (MASLD)
Fat accumulates in liver cells without causing significant inflammation. Often, you might not feel sick at all.
Active MASH
The fat has begun to cause the immune system to react. Inflammation sets in, damaging the liver cells.
Fibrosis
If the swelling persists for a long time, the liver develops scar tissue around cells and blood vessels.
Cirrhosis
The most advanced stage. The liver is heavily scarred, shrinks, and struggles to function properly.
Symptoms of MASH
MASH is often referred to as a silent disease because you can have it for years without feeling unwell. However, as the liver becomes more inflamed, common signs include:
- Feeling very, very tired (severe fatigue)
- A dull ache or discomfort in the upper right side of your abdomen
- Unexplained weight loss or weakness
- Yellow skin or eyes (jaundice), and fluid retention in the tummy or legs
Causes and Risk Factors of MASH
Unlike alcohol-related liver disease, MASH is driven by metabolic factors. You may be more likely to develop MASH if you have:
Insulin Resistance or Type 2 Diabetes
High blood sugar levels increase fat storage in the liver.
Obesity
Particularly, carrying excess weight around the waist.
High Cholesterol
High levels of triglycerides and LDL cholesterol in your blood.
High Blood Pressure
Often seen as part of ‘metabolic syndrome’.
How Does Our Liver Disease Expert Diagnose MASH?
Dr Nadir is an expert at diagnosing MASH accurately without always relying on invasive procedures. Here\u2019s how our fatty liver specialist Birmingham diagnoses:
Specialist Consultation
You will have a thorough 30-minute talk with Dr Nadir to discuss your health, diet, and lifestyle.
Advanced Blood Tests
We check your liver enzymes (ALT and AST) and your metabolic markers, such as blood sugar and cholesterol levels.
Painless FibroScan
A quick, safe ultrasound-based scan. It precisely measures both the amount of fat in your liver and the stiffness (scarring), without using needles.
Multidisciplinary Imaging
If required, our Consultant Radiologists can provide comprehensive ultrasound imaging.

Lifestyle and Nutritional Management
Currently, the most effective treatment for MASH is addressing the underlying metabolic causes. Losing 7% to 10% of your body weight can significantly reduce liver inflammation and even reverse early scarring. At House of Health, Dr Abbas works closely with specialist dietitians and nutrition coaches to build a sustainable, tailored programme for you.
Medical Management
If you have diabetes or cholesterol issues, managing these is crucial. Dr Abbas often collaborates with our Consultant Endocrinologist, Dr Sobia Arshad, to optimise your hormones and metabolic health. Furthermore, he remains at the forefront of emerging medical therapies and targeted medications designed to directly target liver fibrosis.
Advanced Multidisciplinary Care
Treating MASH requires a whole-body approach. As a liver disease expert, Dr Nadir’s main goal is to stop the progression of the disease through a comprehensive, steroid-sparing, and lifestyle-integrated care plan.
- Precision Monitoring: Regular FibroScan assessments allow us to track your liver’s exact response to lifestyle changes without repeated biopsies.
- Team-Based Approach: You have access to our full suite of private GPs, endocrinologists, and weight management services under one roof.
- Advanced Interventions: If standard lifestyle changes do not work, we explore advanced medical and weight-management pathways tailored to your exact metabolic profile.

As a MASH specialist in the UK, Dr Nadir looks after your entire metabolic and digestive system. This means you get seamless, integrated care for your liver, gut, and metabolic health under one roof.

Frequently Asked Questions
Yes. In the early to moderate stages, liver damage from MASH can often be halted and reversed through targeted weight loss, dietary changes, and expert medical management.
MASLD (Metabolic Active Steatotic Liver Disease) simply means there is fat in your liver. MASH means that fat is now causing active inflammation and damaging the liver cells.
Usually, no. Dr Abbas utilises advanced, non-invasive FibroScan technology to accurately measure liver fat and scarring, allowing us to avoid biopsies in the vast majority of cases.
You should avoid alcohol. Although MASH is not caused by alcohol, drinking puts extra stress on an already inflamed liver, accelerating scarring and damage.
Dr Abbas looks at your whole metabolic picture. He uses precise diagnostics to determine the extent of the damage, then builds a tailored programme that combines specialist nutritional support, optimisation of metabolic medication, and regular monitoring to protect your liver.
