This is really weird. The one thing that is known is that drugs like Orgovyx can cause weight gain not weight loss.

I have neither gained nor lost weight since being on Lupron and then Orgovyx, but I have to carefully watch my weight every day and base what I eat on what I weigh.

I hear from a lot of people on weekly advanced prostate cancer meetings I attend complaining about how much weight they have gained, not lost. Give it time you probably will gain it all back.

At one point a couple of years ago (while on Lupron for four years) I lost about 5 pounds and was worried I couldn’t gain it back, that was very short term, gained it all back in a short period.

Being on drugs like Orgovyx can cause you to get belly fat. After seven years I have some, but keeping my weight under control keeps it from getting much of a bearing on my overall weight. That belly fat usually adds weight. Have you noticed that?

Perhaps your RO can just give you the 6 months and be done with it? 7 1/2 months seems like a weird interval - usually done in increments of 6 months.
Also, what do your MD’s say about your weight
loss? Are they concerned? Do blood tests show anything else unusual going on?
Be sure you are getting more protein than you need. muscles can waste away on ADT and all the working out won’t do anything. Possibly low sugar Ensure or Atlas Bars from Amazon might be a good idea.
