Is pid and chlamydia the same thing? clinical doctor said yes but i'd rather an advice from a obgyn.

Yes: Pid stands for pelvic inflammatory disease. This can be caused by chlamydia or other bacteria/organisms. In its early course it causes pain, discharge and fevers. In its later course chronic pain, damage to fallopian tubes and ovaries, pelvic scarring and infertility.

Not quite: Sorry not obgyn, but easy q to answer, chlamidya can cause pid, but it is not the only cause. Pid can be caused by different bacteria, some of which do cause an std's and some of which do not, it can happen during and from pelvic surgeries , abortions, miscarriages, in rare cases pid can be caused by normal but overgrown vaginal flora. And as a urgent care doc i treat a lot of pid's.
