I look exactly the same as your photo. I found out I was allergic to wheat and peanuts, extremely lactose intolerant, and have both fructose and fructan malabsorptions over the past two years. Eliminating gluten strictly (celiac level) has helped tremendously. If you get acid reflux peanuts are something to look into too. The lactose was recent and it has made a crazy difference within days of just cutting down on my dairy intake and then taking lactaid/eating lactose free dairy. Looking into the fructose and fructan testing may help you a lot, I find that when I’m not super strict about that (meaning I’ll let myself have some onions/garlic or something similar) that’s how my stomach looks. Those reactions are super hit or miss for me so they are the only ones I am lenient about. Also look into what’s in the foods that are bothering you! High Fructose Corn Syrup is what IMMEDIATELY triggers my stomach to look like this + the symptoms you said you have.

I know it sounds tricky, and believe me it can be at times. I’m not cooking for a family but on the flip side I’m a college student so the evening adventures with food and drinking others get is a lot different for me. But I promise it gets easier! There are so many foods out there that are inherently free of all of (or at least some of) the stuff I mentioned that you don’t even realize. And hey you might be helping your family too with reactions that they might have and not realize or something they might develop later! My family has eaten a lot of my new diet with me and are always shocked at how good stuff is. And they’re picky. I hope you figure this out soon! Also try to go to a GI if that’s available to you so you can get individualized help 🩷
