Early-stage MASH symptoms are subtle, but they are real. Knowing them can prompt earlier conversations with your healthcare provider. 

Persistent Fatigue and Low Energy 

This is the most frequently reported symptom among people with MASH. But not ordinary, end-of-day tiredness — rather, a deep, ongoing exhaustion that doesn't improve with adequate rest or sleep. 

When the liver is inflamed, its ability to process nutrients and regulate energy metabolism is compromised. The result is a body that feels chronically depleted. Many patients describe it as feeling "heavy" or "running on empty" regardless of how much they sleep. 

Watch for: Fatigue that persists despite adequate sleep, that doesn't have another  obvious explanation, and that has gradually worsened over months — especially in the  presence of metabolic risk factors. 

Discomfort or Dull Pain in the Upper Right Abdomen 

The liver sits beneath the right rib cage. When inflamed or enlarged, it can create noticeable physical sensations in that area: 

• A dull, persistent ache or sense of heaviness 

• Occasional sharper pains or pressure

• Discomfort that worsens after eating — particularly high-fat meals 

This symptom is easy to rationalize as "just gas" or a pulled muscle. But persistent right upper quadrant discomfort, especially when combined with other symptoms on this list, deserves medical attention. 

Unexplained Weight Changes 

Both weight gain and weight loss can be signals. 

Unexplained weight gain — particularly around the midsection (abdominal obesity) — is a major contributor to MASH and one of its early indicators. Abdominal fat is especially metabolically active and drives liver inflammation. 

In later stages, however, some people experience unexplained weight loss. As the liver's function degrades, the body's ability to process proteins, fats, and carbohydrates is impaired — leading to unintentional weight changes the person hasn't tried to achieve. 

Digestive Disturbances 

Because the liver plays a central role in digestion — producing bile, processing nutrients from food, and filtering toxins — MASH can manifest through a variety of GI symptoms: 

• Nausea, especially after fatty meals 

• Bloating or a feeling of fullness 

• Reduced appetite or early satiety 

• Indigestion 

• Irregular bowel movements (constipation or loose stools) 

These are commonly dismissed as ordinary stomach issues. In isolation, they may well be. But combined with other symptoms — or in someone with metabolic risk factors — they may point toward the liver. 

Advanced MASH Symptoms: Signs of Progressing Liver Disease 

As MASH advances toward fibrosis and cirrhosis, symptoms become more pronounced and harder to ignore. These are serious warning signs that require prompt medical evaluation.  

Swelling in the Legs, Ankles, or Abdomen 

Advanced liver disease impairs the organ's ability to produce proteins (like albumin) that regulate fluid balance in the body. The result can be: 

• Edema — swelling in the legs, feet, or ankles 

• Ascites — fluid buildup in the abdominal cavity, causing a distended or bloated belly 

• General puffiness, particularly in the lower body 

Ascites is a particularly significant sign. It indicates substantial liver damage and requires medical management. If you or someone you know experiences significant abdominal swelling, seek evaluation promptly. 

Jaundice: Yellowing of the Skin or Eyes 

Jaundice occurs when the liver can no longer effectively process bilirubin, a yellow compound produced when red blood cells break down. When it accumulates in the bloodstream, it causes: 

• A yellow tint to the skin (especially visible on the face, palms, and torso) 

• Yellowing of the whites of the eyes (scleral icterus) 

• Darker than usual urine (often described as tea-colored or amber) 

• Pale or clay-colored stools 

Jaundice is a serious symptom indicating significant liver dysfunction. It warrants immediate medical attention. 

Skin Changes and Easy Bruising 

The liver synthesizes clotting factors — proteins essential for normal blood clotting. When it's severely damaged, these levels drop, and the consequences appear on the skin: 

• Easy bruising from minor bumps or pressure 

• Small red or purple spots under the skin (petechiae) 

• Itchy skin — caused by bile salt accumulation when liver function declines 

Persistent unexplained itching or noticing that you bruise far more easily than before, can be a subtle signal of declining liver function. 

 Cognitive Changes and Mental Fog 

One of the more alarming manifestations of advanced MASH is hepatic encephalopathy — a condition in which toxins that the liver normally filters begin to accumulate in the bloodstream and reach the brain. Symptoms include: 

• Difficulty concentrating or following conversations 

• Forgetfulness and memory lapses 

• Mental fogginess or confusion 

• Personality changes or unusual irritability 

• In severe cases, disorientation or altered consciousness 

Hepatic encephalopathy does not typically occur in early MASH. Its presence suggests significant, advanced liver damage. However, it's worth noting because it can sometimes be mistaken for dementia or mental health conditions — delaying correct diagnosis.
