Příprava na fibroskopii: co musíte vědět před vyšetřením jícnem a žaludkem

When you're scheduled for a fibroskopii, endoskopické vyšetření horního trávicího traktu pomocí pružného optického přístroje. Also known as gastroskopie, it is the most accurate way to see what's really happening inside your esophagus, stomach, and the first part of your small intestine. This isn't just a routine check—it's often the key to finding out why you've had constant heartburn, trouble swallowing, unexplained weight loss, or black stools. And if you skip the prep, you might as well skip the whole thing.

Fibroskopie isn't magic. It needs clean, empty passages to work. That means no food for at least 6–8 hours before. Water? Usually allowed up to 2 hours before, but check with your clinic. Smoking? Absolutely not for at least 24 hours—it irritates the lining and makes it harder to spot early changes. Alcohol? No way. Even one drink the night before can mess with your body’s response and blur the results. And if you take blood thinners, diabetes meds, or supplements like garlic or fish oil, you need to talk to your doctor days ahead. This isn't about being difficult—it's about making sure the doctor sees everything clearly.

Many people think fibroskopie is the same as kolonoskopie, but they're not. One checks your bottom end, the other your top. But the prep rules? They’re similar in one big way: příprava na fibroskopii isn’t optional. If your stomach isn’t empty, the doctor might miss a small ulcer, a polyp, or early signs of cancer. And if they can’t see clearly, they might have to reschedule you—and that means more stress, more waiting, and more cost. You don’t need to starve yourself for days. Just follow the simple window: no solid food after midnight, clear liquids only until a few hours before. No milk, no soup, no juice with pulp. Water, black tea, or clear broth are your friends.

And don’t forget the mental prep. Most people are scared of the tube. But it’s not like in the movies. You’ll get light sedation. You’ll feel drowsy. You might not remember much. The whole thing takes 10–15 minutes. The real work happens before—when you follow the rules. This isn’t about being perfect. It’s about being smart. If you do the prep right, you get answers. If you don’t, you get guesswork.

What you’ll find below are real, practical guides from people who’ve been there. From how to eat three days before a fibroskopie, to what happens right after, to why some people need this test instead of a capsule endoscopy. You’ll see how fibroskopie connects to rektoskopie, gastroskopie, and even how black stools can point to something serious. No fluff. No theory. Just what you need to know to walk in prepared, calm, and confident.
