Gastroesophageal reflux disease

Gastroesophageal reflux disease, also known as GERD, is a condition where your tummy stuff sneaks up into your food pipe (Esophagus). It can happen when you eat too much or when you lay down right after eating. The “stuff” in your tummy is called stomach acid, and when it sneaks up into your food pipe, it can hurt and make you feel bad.

You know when you burp sometimes, and it feels like a little bit of your dinner is coming up with it? Well, imagine that feeling, but it keeps happening over and over. That's what people with GERD feel like. Sometimes it can even make you throw up.

You might think, "Well, can't you just not eat so much?" But sometimes even small meals can trigger GERD. People with GERD need to be careful about what they eat and when they eat. They might also need medicine to help manage the symptoms.

So, in summary: GERD is when your tummy stuff comes up into your throat and causes discomfort. It happens when you eat too much, lay down right after eating, or have certain foods. It can be managed with careful eating and medication.
