The specific dietary restrictions before an endoscopy can vary depending on the type of endoscopy and your healthcare provider's instructions. However, in many cases, you will be asked to follow these general guidelines:

1. Fasting: In most cases, you will be instructed to fast (not eat or drink) for a specific period before the endoscopy. Fasting is necessary to ensure a clear view of the area being examined and to reduce the risk of complications during the procedure. The duration of fasting can vary, but it's typically at least 6 to 12 hours before the procedure.

2. Clear Liquids: In some situations, you may be allowed to consume clear liquids up to a certain point before the endoscopy. Clear liquids include water, clear broths, clear fruit juices (without pulp), and clear sports drinks. Avoid liquids that are red or purple, as they can sometimes be confused with blood during the procedure.

3. Avoid Solid Foods: You should avoid consuming solid foods during the fasting period before the endoscopy. This includes all types of solid foods, including solid snacks, fruits, vegetables, and meats.

It's essential to follow your healthcare provider's specific instructions regarding fasting and dietary restrictions before your endoscopy. Failure to do so can affect the quality of the examination and may lead to the rescheduling of the procedure. If you have any questions or concerns about what you can eat or drink before the endoscopy, be sure to discuss them with your healthcare team in advance. They can provide you with detailed and personalized guidance based on your specific situation and the type of endoscopy being performed.
