3. Swollen Ankles
Swelling in the ankles, known medically as peripheral edema, can be a sign that the liver is failing to maintain fluid balance in the body. When liver function declines, protein production—particularly albumin—drops. Albumin helps keep fluid within blood vessels; without enough albumin, fluid leaks into surrounding tissues causing swelling.
Additionally, liver dysfunction can cause portal hypertension, increased pressure in the portal vein that carries blood from the intestines to the liver. This pressure contributes to fluid accumulation in the legs and abdomen (ascites). If you notice persistent swelling in your legs or ankles, especially if accompanied by fatigue or abdominal discomfort, it’s important to get a liver ultrasound and blood tests to assess liver function.
4. Dark Urine
Dark-colored urine is a subtle yet important indicator that the liver’s ability to process bilirubin is impaired. When bilirubin is not excreted properly into the bowel, it leaks into the bloodstream and is filtered by the kidneys, coloring the urine dark amber or brown.
Unlike dehydration, which can also darken urine, liver-related dark urine usually appears alongside other signs such as pale stools or jaundice. If you observe a persistent change to a darker urine color without changes in fluid intake, consult your healthcare provider for liver function testing and possibly imaging to identify bile duct issues or liver inflammation.
5. Brain Fog and Fatigue
The liver plays a crucial role in detoxifying ammonia and other waste products from the bloodstream. When liver function declines, these toxins build up and can affect brain function, causing confusion, difficulty concentrating, and persistent fatigue. This condition is sometimes called hepatic encephalopathy.
People may describe this as feeling mentally sluggish or “foggy,” often accompanied by irritability or mood changes. Chronic fatigue related to liver dysfunction is not relieved by rest and may worsen over time. If you experience unexplained cognitive changes or severe fatigue, it is important to have liver enzymes and ammonia levels checked. Early diagnosis and treatment can help prevent progression to more severe neurological impairment.
