Constant Bloating? Help!

Hi everyone. I’m just posting here because I have alot of stomach issues and although I’ve made so many changes It has barely improved. Posted, is a picture of me not bloated (and not sucking in) verses a picture of me bloated (and not sucking in). The bloating is so incredibly bad that I look and feel pregnant aswell as having really uncomfortable side effects. I’ve taken a food intolerance test and have followed it for the most part as well as having started taking lactose pills. I also have started eating much healthier whole foods rather than junk food (which is a challenge as I’m a college student lol) I eat pretty little meat and fatty products and eat a lot of fibre and fruits/vegetables. It’s important to note that although I have gone to the doctors all they have said is I must have ibs and that’s it so I’m at a loss for ideas/solutions. Anyone have any suggestions or advice? Thanks!
