Recovery after Gastro?

I’m hoping I can ask this here and I’m sorry if this is the wrong place!

How do you recover after a stomach bug? I’m usually pretty good about colds and stuff like that but this is the first time I’ve had gastro and am now recovering while also trying to lose weight in a deficit and going to the gym 2-3 times a week.

I’ve struggled with hitting my protein goals, staying in a calorie deficit and having anywhere near the amount of energy I had before getting sick. It’s been a week almost since I’ve started recovering and no matter what I eat my stomach is incredibly sensitive. I’m over eating just to satiate the nausea I get from not eating and my usual goal of 200g protein per day is almost completely unattainable.

For reference I’m 232lbs 6’2 male and have been on a weight loss journey for a bit now but hardcore in the last few months to lose weight for my brothers wedding in October. I’ve lost 20lbs since June 1st and have been fine up until this run in with gastro. I also take 5g creatine daily and have been since June.

I’m worried about losing my progress, gaining weight while trying to recover and also not being able to continue how I was prior to this

I appreciate any tips, insights and advice. Thanks in advance!
