Cholecystitis is a swelling and irritation of your gallbladder, a small organ in the right side of your belly near your liver.
The gallbladder’s job is to hold a digestive juice called bile. It releases bile into your small intestine when your body needs it to break down fats. But if the path to your small intestine is blocked, bile gets trapped. That backup can irritate your gallbladder. That’s how cholecystitis happens.
Nausea and vomiting are common symptoms. They often show up after you’ve eaten a big or especially fatty meal.
It’s easy to mistake cholecystitis for other health problems, but another telltale sign is intense pain -- in your belly, in your back, or under your right shoulder blade.
If you don’t see a doctor and get treatment, it can lead to dangerous infections or become a long-term condition. The most common solution is surgery to remove your gallbladder.
