I have severe right side pain after eating fatty foods. I have slight right side pain after eating healthy foods. My ALT and AST are elevated.?

Betting on GB. Sounds like you may have a gallbladder issue. Should see your doc to obtain further studies and imaging. Elevated alt/ast need an explanation.
Probably gallbladder. This is likely related to gallstones but increased alt/ast are atypical. See doc & get tests. If due to gallstones most docs advise surgery but i've had many patients have great success with natural therapies to dissolve gallstones & flush them out of the liver/gallbladder.
