Gastric complaints that can be linked to liver issues include upper abdominal pain, nausea, loss of appetite, and bloating. Other symptoms often seen alongside these gastric issues are fatigue, jaundice (yellowing of the skin/eyes), dark urine, and pale or clay-colored stools. When the liver is very scarred, a serious symptom can be vomiting blood or having black, tarry stools, requiring immediate medical attention.
