Constipation, gas and passing mucus are signs of possible IBS as well as feeling full and diarrhoea.  You could ask for a colonoscopy, CT and ultrasound to rule out other conditions.  Have a look at the Fodmap diet to identify food triggers.

thanks , I did colonscopy 3 years ago is ok ,

i try to eat fodmap diet but i have gas with vegetables without carbs too.

 and only meat i have costipation,  

but I don't understand why mucus smell like fishy and i have many many gas bubbles inside mucus  

Ask your doctor about IBS. Your doctor can diagnose IBS if all your tests are negative. You will probably have to avoid the foods that are giving you symptoms and ask to be referred to a dietician to get a diet plan that will still give you essential nutrients.  Or, you could take supplements to replace vitamins and minerals.

, yes , but if fruits (sugar) give me problems carbs too like many vegetables , what I can eat to put weight? ,  is not possible that I have some other problem ?

You will need to see your doctor for further tests to establish if you have something other than IBS.  You could try Complan or Fortsip to build you up but advice on diet from your doctor/dietician is your best option.

I have the same problem. Fasting anda liver flushes, and moments fruitarian and moments eating egg turn my opinion about it confuse. I think are fermentable carne residues (fibers, starch) with rotten protein residues inside the bowel, together with a constant flow of a bile fluid who is mixed inside the liver with a lot liposoluble toxic metabolic. All this together shape the substrate to a possibility to exist diferent microbiologic species inside your bowel.

I think gran-negative, maybe proteus. The microbiome create toxins like endotoxins lipopolisacharides from gran-negative and mycotoxins from fungus.
