This condition is called peripheral edema.
It occurs when excess fluid accumulates in the tissues, particularly around the ankles, feet, and lower legs.
Several mechanisms may contribute to edema in people with significant liver dysfunction.
One important factor is reduced albumin production.
Albumin is a protein made by the liver that helps maintain fluid balance within blood vessels.
When albumin levels become very low, fluid may move into surrounding tissues.
Portal hypertension and changes in kidney-related hormone systems can also contribute to sodium and water retention.
As a result, fluid may accumulate in the legs and abdomen.
However, swollen ankles are not specific to liver disease.
Heart failure, kidney disease, venous insufficiency, prolonged standing, and certain medications can also cause swelling.
When to pay attention: Persistent unexplained swelling, particularly when combined with abdominal enlargement or other possible liver symptoms, should be assessed.
Sudden swelling in one leg, especially with pain, redness, or warmth, requires urgent evaluation because a blood clot may be responsible.
7. Persistent Itching Without an Obvious Rash
Unexplained itching can sometimes be an early symptom of certain liver and bile duct disorders.
The medical term is pruritus.
It may occur when the normal flow of bile becomes disrupted.
This is particularly relevant in cholestatic conditions, where bile formation or movement through the bile ducts is impaired.
The biological mechanisms behind liver-related itching are complex and involve several circulating substances and nerve-signaling pathways.
Some people experience itching across large areas of the body.
Others notice it particularly on the palms of their hands or soles of their feet.
In certain cases, itching becomes more noticeable at night and interferes with sleep.
Importantly, the skin may look completely normal.
There may be no obvious rash or visible inflammation.
However, itching is common and can also be caused by dry skin, allergies, eczema, kidney disease, thyroid disorders, and medication reactions.
When to pay attention: Persistent generalized itching without an obvious explanation deserves medical evaluation, particularly if accompanied by jaundice or dark urine.
8. Loss of Appetite, Nausea, and Unexplained Weight Loss
Changes in appetite can occur in people with liver disease.
Some individuals experience nausea, an uncomfortable feeling after meals, or a reduced desire to eat.
These symptoms may develop because of altered metabolism, inflammation, digestive disturbances, and complications associated with advanced liver disease.
People with cirrhosis may also experience early satiety, meaning they feel full after eating only a small amount.
Ascites can contribute to this problem by increasing abdominal pressure.
Over time, inadequate food intake and altered metabolism may contribute to malnutrition and muscle wasting.
Unintentional weight loss is particularly important.
A person may notice that clothing becomes looser even though they have not intentionally changed their diet or exercise routine.
However, appetite loss and weight loss have many possible causes, including gastrointestinal disorders, thyroid disease, infections, depression, and cancer.
When to pay attention: Persistent nausea, reduced appetite, or unexplained weight loss should not be ignored.
A healthcare professional can determine whether liver testing or other investigations are necessary.
9. Spider-Like Blood Vessels on the Skin
Certain people with chronic liver disease develop small, visible blood vessels near the surface of the skin.
These are known as spider angiomas or spider telangiectasias.
They typically have a small central red spot with thin blood vessels radiating outward, creating an appearance similar to a spider.
They may occur on the face, neck, upper chest, and arms.
Spider angiomas can be associated with cirrhosis and other conditions involving altered hormone metabolism and vascular regulation.
However, they can also occur in healthy people, during pregnancy, and in other circumstances.
A few isolated spider angiomas do not automatically indicate liver disease.
The presence of multiple lesions, especially alongside jaundice, abdominal swelling, or other concerning findings, may justify further assessment.
When to pay attention: New clusters of spider-like blood vessels should be discussed with a healthcare professional if other symptoms or risk factors for liver disease are present.
10. Confusion, Memory Problems, and Changes in Mental Alertness
One of the most serious complications of advanced liver disease is hepatic encephalopathy.
This condition affects brain function and can occur when severe liver dysfunction and changes in blood flow allow substances to accumulate and influence the nervous system.
Ammonia is one substance involved, although hepatic encephalopathy is caused by multiple metabolic and inflammatory processes.
Symptoms can range from subtle changes in concentration to severe confusion and loss of consciousness.
Early signs may include:
-
Difficulty concentrating.
-
Changes in sleep patterns.
-
Forgetfulness.
-
Mood changes.
-
Unusual irritability.
-
Slower thinking.
-
Confusion about time or surroundings.
In more severe cases, people may become extremely drowsy or unresponsive.
A physical sign sometimes associated with hepatic encephalopathy is asterixis.
This is an involuntary flapping movement of the hands that may appear when a person holds their arms out and extends their wrists.
Hepatic encephalopathy is a medical complication that requires prompt treatment.
It can sometimes be triggered or worsened by infections, gastrointestinal bleeding, constipation, dehydration, electrolyte disturbances, or certain medications.
When to pay attention: New confusion, marked drowsiness, unusual behavior, or difficulty staying awake in someone with known or suspected liver disease requires emergency medical assessment.
Why Does Liver Disease Develop?
Understanding the possible warning signs is important, but knowing what causes liver disease is equally valuable.
Several conditions can damage liver cells or interfere with normal liver function.
1. Metabolic Dysfunction-Associated Steatotic Liver Disease
MASLD is a condition involving excessive fat accumulation in the liver in association with metabolic risk factors.
It is commonly associated with:
-
Excess body weight.
-
Insulin resistance.
-
Type 2 diabetes.
-
High triglyceride levels.
-
Abnormal cholesterol levels.
-
Metabolic syndrome.
Some people develop inflammation and progressive scarring, a condition known as metabolic dysfunction-associated steatohepatitis, or MASH.
Over time, a proportion of people with progressive disease may develop cirrhosis.
2. Alcohol-Related Liver Disease
Excessive alcohol consumption can damage liver cells.
The disease may progress through several stages, including fatty liver, alcohol-associated hepatitis, fibrosis, and cirrhosis.
Not everyone develops liver disease at the same rate.
Risk depends on several factors, including drinking patterns, genetics, sex, metabolic health, and other medical conditions.
Avoiding alcohol is particularly important for people with alcohol-related liver disease.
3. Viral Hepatitis
Hepatitis viruses can cause liver inflammation.
Hepatitis B and hepatitis C are important causes of chronic liver disease worldwide.
Some people experience few or no symptoms for many years.
Without appropriate diagnosis and treatment, chronic infection may lead to fibrosis, cirrhosis, or liver cancer.
Vaccination is available for hepatitis A and hepatitis B, while effective antiviral treatments are available for hepatitis B and hepatitis C.
