These are active providers in Oregon whose primary NUCC specialty treats unexplained weight loss; it is not a list of providers confirmed to treat your specific case, and absence does not mean a provider does not treat it. Ordering reflects NPPES profile completeness and registry tenure — a transparency signal, not a quality, outcome, or "best" ranking. Condition-to-specialty mapping: MedlinePlus, NIH, ABMS.
