I have experienced loss of appetite for the past year or so..everyone is always on my case about not eating..honestly I believe it's caused from the depression that comes with the diagnosis.. I know for me it's hard to get my mind to believe I can't do as much as I used to.

I got this either about a couple of month ago. Interestingly I loose little weight considering that I almost eat nothing for an adult man! Eating now become a nightmare for me! This disease is really weird with shocking and also interesting gifts every now and then!

I hope you get to feeling better ! I have lost my appetite about 3mths ago lost 30 pounds just like you my daughters tell me I need to eat I agree depression has alot to do with it I became disable at 32 years old it's hard but we have to be tuff and try to stay positive hang in there lady I'm new to this website but Im here and it might get me down but I still going to try to pick myself up and take it one day at a time .

I've had the same problem. Often nauseated, very low appetite, worried about not getting enough nutrients. The fact is, since I move a lot less, I don't spend a lot of energy, it's quite normal to be less hungry. Plus nausea doesn't help. As the others suggested you could take some meal substitute shakes, but I suggest you talk to your pharmacist to pick the right one for you since there are many different kinds! But what helped me the most is choosing food that I really want to eat. My diet wasn't the most balanced and healthiest it could be but at least I was eating more! Hope this helps, take care!

Depressed? (can be the case even if you don't register it) Maybe even the nausea which in my experience can come as part of 'the Fibro package deal'...
This random appetite thing happens to me all the time... it's odd to be aware of deep hunger yet food is still a no-go...

There's probably a bunch of direct/indirect Fibro related causes, none of which will show in tests. As Cathy advised, for now get something with all the nutrients you're otherwise missing that can be made into a drink; Slim Fast, Weight Gain (whey protein etc), Huel... any or either that's marketed as a supplement or replacement for meals will help fill the gaps for now.
Just be sure to let your doctor know you're strategising in case of any dietary or med related clashes.
