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:
Cause | Probability | Status |
---|---|---|
Increased Intestinal Permeability | 97% | Confirm |
Chronic Renal Insufficiency | 26% | Unlikely |
Pyroluria | 14% | Unlikely |
Congestive Heart Failure | 2% | Ruled out |
Fluorosis | 0% | 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).
Ongoing IBS can lead to chronic nausea in various ways:
Most cases of acute pancreatitis resolve within a week; chronic pancreatitis does not resolve itself and results in a slow destruction of the pancreas.
