Hello, my name is Dr.Dorina Gurabardhi. I understand your concern. 
Some advices that I can give to you are:
-avoiding artificial sweeteners, which may cause 
bloating.
-drinking plenty of water, which helps to reduce 
constipation.
-eating a diet that contains high-fiber foods that promote digestion, such as fruits, vegetables, and whole grains.
-eating several small meals per day instead of fewer larger ones
-exercising regularly
-Try taking over-the-counter gas-reducing medications, such as 
simethicone drops and continue with digestive enzymes, to help relieve bloating.
Hope my answer was helpful, if you have any other questions I'll be glad to help, thanks!
