Intestinal Infection: Causes, Symptoms, and What You Can Do

When you have an intestinal infection, a harmful microorganism invades your digestive tract, causing inflammation and disrupting normal function. Also known as gut infection, it’s one of the most common reasons people visit doctors—or just stay home with a heating pad. It’s not just about feeling sick. It’s about sudden cramps, watery diarrhea, nausea, and sometimes fever that hits fast and hits hard.

Most intestinal infections, are triggered by bacteria, viruses, or parasites from contaminated food, water, or poor hand hygiene. Common culprits include E. coli, Salmonella, norovirus, and Giardia. You don’t need to travel overseas to catch one—undercooked chicken, unwashed veggies, or even a dirty kitchen sponge can be the source. And while some cases clear up on their own, others need real medical attention, especially if you’re elderly, pregnant, or have a weak immune system. The link between food poisoning, a type of intestinal infection caused by eating contaminated food and your daily habits is stronger than most people think. It’s not just about restaurants. It’s about how you store leftovers, whether you wash your hands after using the bathroom, and if you let your kids lick spoons after tasting raw cookie dough.
