Bitter taste sensation can have various causes, ranging in severity from 'troubling' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose bitter taste sensation, we could:
|Infectious Mononucleosis||4%||Ruled out|
|Pancreatic Cancer||0%||Ruled out|
|Diabetes II||0%||Ruled out|

Jaundice also suggests the following possibilities:
Jaundice is a yellowing of the skin and eyes that occurs when the diseased liver does not process enough bilirubin.
The gallbladder releases bile into the small intestines through a tube called the cystic duct, which connects to the bile duct. When gallstones are obstructing these ducts, bile builds up in the gallbladder and increases the concentration of a yellowish substance called bilirubin in the blood, causing a yellowing of the skin known as jaundice.
Malaria can cause jaundice through the loss of red blood cells.
