Difficulty losing or gaining weight can have various causes, ranging in severity from 'worrying' to 'life-threatening'. 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 difficulty losing or gaining weight, we could:
|A Weight Problem||27%||Unlikely|
|Gluten Sensitivity||3%||Ruled out|
|Diabetes II||2%||Ruled out|
|An Underweight Problem||2%||Ruled out|
