Single row update using primary key affects many rows

Question

I'm doing a very simple datetime update in a table using its primary key:

update TABLE 
set END_DATE = '2015-10-14 00:00:00' 
where ID = 1165027;

I received the message (1 row(s) affected) 183 times!

When doing a select only one row is returned:

select * from TABLE where ID = 1165027;

What am I missing?

There are one or more trigger(s) on your table.

The multiple (1 row(s) affected) messages are generated not just by your single-row update statement, but also by other statements in the triggers fired from that original action.
