Weak appetite 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 weak appetite, we could:
|Congestive Heart Failure||99%||Confirm|
|Valley Fever (Coccidioidomycosis)||18%||Unlikely|
|Cirrhosis Of The Liver||4%||Ruled out|
|Atrophic Gastritis||0%||Ruled out|
|Kidney Disease||0%||Ruled out|
|Irritable Bowel Syndrome||0%||Ruled out|
