Chronic nausea can have various causes, ranging in severity from 'minor' 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 chronic nausea, we could:
|Increased Intestinal Permeability||97%||Confirm|
|Chronic Renal Insufficiency||26%||Unlikely|
|Congestive Heart Failure||2%||Ruled out|
|Diabetes II||0%||Ruled out|
|Intestinal Obstruction||0%||Ruled out|
|Gallbladder Disease||0%||Ruled out|
If you suffer significantly from unexplained nausea (at least once per week), for how long has this been a problem?
Possible responses:→ It is not a problem / don't know
→ It started within the last week
→ It started within the last month
→ I've had it for 1 to 3 months
→ I've had it for over 3 months
Approximately 50% of patients with chronic idiopathic nausea and vomiting evaluated in referral centers have gastroparesis. A viral etiology was suggested in these patients and in other series when there was an acute onset of nausea and vomiting with other features of a viral illness (fever, myalgia, diarrhea, fatigue, or abdominal cramping).
Most cases of acute pancreatitis resolve within a week; chronic pancreatitis does not resolve itself and results in a slow destruction of the pancreas.
