"Ah, estás embarazada!" My partner's aunt exclaimed, gesturing to my stomach, which I'd been rubbing inconspicuously (I thought) since we sat down at her family's kitchen table. I was not, in fact, pregnant with my first child, though the confusion was understandable: My stomach was bloated to second-trimester size, and even if my Spanish was perfect I wouldn't have been able to explain why.
Sufferers share their stories this Endometriosis Awareness Month.

For a woman in her 30s in the year 2023, having a messed-up belly is hardly a unique occurrence. An estimated 40 percent of the global population has some sort of functional gastrointestinal disorder (FGID), the most well-known of which is irritable bowel syndrome (IBS). These disorders present in women twice as often as men. FGIDs are basically any type of tummy troubles that have vaguely mysterious origins and don't show up as abnormalities in standard blood tests, X-rays, or other diagnostic tools. IBS usually presents as chronic, extreme stomach pain and abnormal bowel movements; you can have IBS- C(onstipation), IBS-D(iarrhea), or IBS-M(ixed).
People have been feeling sick to their stomach for centuries, but thanks to social media it seems like everyone’s finally talking about it. (TikTok's official declaration is that all hot girls have stomach issues.) And since FGIDs disproportionately affect women, some might even call it a feminist act to post about poop.
For most people with IBS, the road to a diagnosis is long, uncomfortable, and can start only when you do something many don't: Ask your doctor for help. While it used to be widely accepted that IBS and other FGIDs were caused by neurological disorders, doctors now are less convinced this is the case. However, people with IBS still tend to be people with anxiety. "Two-thirds of the anxiety among patients with IBS happens after the disease starts," says Mark Pimentel, MD, a gastroenterologist, and the executive director of the microbiome-focused Medically Associated Science and Technology (MAST) Program at Cedars-Sinai in Los Angeles. A large part of this is due to what might be the most frustrating feature of the disease: its unpredictability. If I knew that my flare-ups would come every time I ate pizza, I'd probably just stop eating pizza (...probably). But sometimes I eat pizza and I'm totally fine in the morning; other times I eat the exact same pizza from the exact same pizza shop, wake up with debilitating stomach pains, and have to spend the better part of the day having explosive diarrhea. "That's classic IBS," Dr. Pimentel assures me when I tell him this. "Your symptoms are irregular and unpredictable…[Patients with IBS] can't plan and that's also anxiety provoking." So while it's possible that anxiety could also make GI symptoms worse (the connection there has yet to be proven), "IBS makes people anxious because they can't just be relaxed," he says. In my case, this symptom rollercoaster combined with anxiety about bothering anyone (including my doctor) over something that felt like it could be a fluke delayed my seeking formal treatment.
