Summary. 1  It is important to differentiate physiologic flushing from flushing associated with more serious diseases. 2  Distinguish wet flushing from dry flushing. 3  Look for flush distribution, triggers, reproducibility, and associated symptoms. 4  Do not forget to look for drugs that are known to cause flushing. Alcohol and certain foods can cause physiologic flushing but may also trigger flushing in carcinoid syndrome. The character of the flushing in carcinoid syndrome depends on the location of the tumor.
