I'm Joe Proietto.
I am a Professor Emeritus at
the University of Melbourne.
I will be talking about
"Pharmacotherapy for Obesity".
There are two parts to
this talk. Two lectures.
Part 1 shows you why it's
necessary to have
pharmacotherapy for the rest
of the life of the patient and
Part 2 will talk about the agents
that we have at the moment.

Before I start, I'd like to
declare possible
conflicts of interest.
I've given lectures on the
management of obesity for
Novo Nordisk who markets
Saxenda and Wegovy
around the world,
and for iNova here in
Australia who are marketers
of Duromine and Contrave.

There are many factors that
can influence body weight.
A lot of these are said
to be able to lead to
obesity and these include
the built environment.
In other words, the
lifestyle we have
now in modern times.
Medical conditions
such as, for example,
Cushing's syndrome
or hypothyroidism.
There's quite a bit
of literature about
the microbes that live in
our large bowel
affecting weight.
There's evidence for some
viruses influencing weight.
There are medications
that can change
weight such as steroids
and antipsychotics,
sleep deprivation, stress.
Menopause is known to
cause some weight gain and
some environmental toxins.
