Has anyone experienced unexplained significant weight loss either from eliminating DAs or from getting iron infusions?
I started having unexplained weight loss last Fall. I've gone from 205 lbs to 170 since September 2018 (I may have leveled off now at ~170). I had an iron infusion in August 2018 and another in December 2018. (Both have really helped with RLS.) Then I eliminated all DAs starting in October 2018 and finishing in February 2019.
During this time, I also introduced and gradually increased methadone up to my current level of 15 mg. to replace the dreaded DAs. I've also been taking 1500 mg gabapentin/day this whole time. I'm now blessedly free of all DAs after a hellish withdrawal. This combo of 2 medications, plus the iron infusions, has now produced complete control of my RLS symptoms almost all the time.

I'm at 170 lbs, which is a healthy weight for a 6'2" male. I do still feel pretty healthy, with good strength for a 70-year-old. Able to walk several miles and do some weight work. Just a little more fatigue at times.
There's one more thing I may look into: thyroid. It's possible my thyroid is overactive.
Thanks. Again, I have been checked for medical causes, all clear. Only new symptom is a little more fatigue at times, but it's mild. Generally feeling pretty good.
But you've given me another possible clue: gabapentin. I've been taking gabapentin plus a DA for many years. I just went back and looked at my RLS diary from last Fall and found that back then, before my 2nd iron infusion helped reduce my RLS symptoms some more, i was taking 1800 to 2100 mg gabapentin a day. Now I'm taking 1200/day (I incorrectly reported that as 1500 mg). So now I'm wondering if the decrease in gabapentin might be a contributing factor in the weight loss.
Again, it looks like my weight has stabilized at around 170 lbs, which is a perfectly normal weight for a 6'2" male. But I'd be happier if I knew what caused this weight loss.
I am currently on 5 mg of Methadone which has blessedly given me a new lease on life because my RLS is 95 percent gone. I have lost 20 pounds. I have attributed it to being able to greatly reduce Lyrica from 300 mg to 75mg, but I have also wondered if the Methadone is partly responsible for my weight loss as my appetite has decreased as well.
Lyrica is an appetite stimulant and can cause weight gain, as you realise. Your weight loss may be in part due to reducing it.
it appears rls optimist is LOSING weight DESPITE taking Gabapentin.You should not expect this.
Additionally, opiates do not directly affect appetite, they can however cause nausea and vomiting and it's this that ruins appetite. If the opiate is NOT causing nausea, then again you would not expect weight loss.
Any unexpected or unexplained weight loss requires medical investigation.
I would love to get by on less methadone. And I have tried to reduce it several times, by small increments, but it is not to be. It's a trade off: I have to increase my gabapentin dose by more than I'm comfortable with (300-600 mg or more) in order to decrease the methadone. My experience is that I have fewer side effects with this combination than if I drop the methadone a little and boost the gabapentin.
I'm glad you're able to get by on 6 mg methadone. Long may it last. Are you taking anything else?
No, nothing else. For a while I was on methadone occasionally, together with pramipexole.
After an horrific daytime attack I decided to go it alone on methadone.
The methadone worked vastly better alone than in tandem, and did not interfere with sleep at all. I immediately started sleeping through the night.
The point of this is that maybe methadone is a drug best used alone if possible. Or it may be that only dopamine agonists interfere with other drugs. We just don't know. Nor do the doctors or the pharmacists.
Both the DAs and the anticonvulsants mess with the brain in complex ways, and it is reasonable to assume that combinations of mind-benders may make things worse.
When I dropped one the result was gobsmacking. I can still barely believe it, eight months later.
But I am absolutely sure that a combination of a DA and pramipexole would not have been the same at all.
And I am sure that the methadone causes weight loss if one is not wary. I am slight and have no extra to lose, so when I starting dropping kilos and my trousers fell off I took great care that it would not continue.
Well, how interesting. That's very inspiring. I may well try something similar, reducing the gabapentin as low as possible, hopefully to zero. I believe it's considered unwise to drop from 1200 mg to 0 all at once, so I'll go down gradually. Then if I get to zero, after a little while I'll see if I can reduce the methadone.
No guarantees, but if I go this route, I'll keep you posted.
I agree that significant weight loss is something that should be looked into by a medical practitioner. For what it's worth, I lost quite a bit of weight after I withdrew from pramipexole (once I got my regime under control). I think that the dopamine agonist caused a degree of compulsive eating in me (as well as significant compulsive shopping) and that compulsion fell away when I stopped it - as did the weight! I was on a high dose of pramipexole however - 1.6mg.
Thank you all for your replies. Sorry for my delay in responding. Not to worry: I have certainly seen several doctors and been tested for all the serious possibilities (various cancers, heart issues, celiac disease), all thankfully negative. And I didn't think I'd made enough changes in diet or eating habits to explain the loss. That's why I'm investigating these other possibilities.
However, since you mentioned losing weight after eliminating pramipexole, dancer, I'm now thinking that I may have been doing more compulsive eating before my DA elimination than I realized. One thing I do remember is that I pretty much stopped eating ice cream around that time; there could well have been other changes I didn't remember. Thanks for the tip.
To stress the point, I would ignore any thoughts about whether stopping or starting any drugs causing you to lose weight for now. It may be that, but it's really in your best interest to see your doctor.
