Is any of this happening?
Be seen today
Seek prompt medical assessment if spider angiomas appear with yellow skin or eyes, persistent abdominal swelling, unexplained weight loss, marked tiredness, easy bruising, or dark urine.
These symptoms do not prove that liver disease is present, but they should be assessed.
