He is very skinny but he has a huge tummy with a lots of gasses 🙈 He doesn't has any diarrhea, not fever, he got good appetite, plays but he is weak and sleeps a lot. What can I do? Any suggestions? What kind of test? Any medicine? 🙏🙏🙏  

Hello - it sounds as though your vet has done some initial investigations, including blood tests, which I have seen.  These tests will have helped to rule some possibilities out and they should now have a shortened 'differentials list' ie a list of things that could be causing the clinical picture that they can see.   Ask them about this - I think that medical investigations can appear very opaque to clients but, when you appreciate what tests are being done, what has been ruled out and and how they are helping, it can help to give you more confidence in the process.   Good questions include 'what could still be causing these signs?'   And 'Should we try to narrow these possibilities down further, or can we try to treat the problem?'   Sometimes, vets will try to treat the patient eg  give fluids to keep the patient hydrated, before proceeding with investigations.   Human medics work in a similar way; not every mystery can be solved on day one, but by following a logical process, your vet should be able to whittle it down to the correct cause while keeping the patient as stable as possible.  Ideally, they will tailor their focus to.suit the needs of the individual situation and patient.  I hope that something here will be of help.
