I’ve been having some minor health issues recently, and my GP recommended a colonoscopy for a thorough check-up. To be honest, just hearing the word ‘colonoscopy’ made me a bit nervous, as I’d heard all sorts of daunting stories about the experience. However, after going through the entire process here in Spain, I found it to be much easier than I expected. So, I decided to start this thread to share my full experience with anyone who might need it.
Appointments and Preparation
The process started with an appointment with my family doctor. After explaining my symptoms, the doctor gave me a referral to schedule an appointment with a specialist at a designated public hospital. I took the referral to the hospital’s ‘atención al cliente’ (customer service) desk, where they entered my information and told me to wait for a letter at home. About three weeks later, I received the letter from the hospital. It clearly stated the date, time, and location of the procedure, along with detailed preparation instructions and two boxes of bowel prep solution.

The most important part is the dietary control and bowel prep in the days leading up to the exam. This was definitely the most challenging part of the whole process. Following the instructions, I started a low-residue diet three days prior, mainly eating things like white bread, rice, chicken breast, and fish. The day before the procedure, I could only consume clear liquids, such as water, clear broth, and apple juice. Starting in the afternoon, I had to drink those two large bottles of bowel prep solution—with its indescribable taste—in intervals according to the instructions. I recommend pinching your nose while drinking it or having another clear beverage on hand to alternate with, as it can be quite nauseating.
On the Day of the Procedure
My appointment was scheduled for the next morning, so after finishing the prep solution and emptying my bowels the night before, I didn’t eat or drink anything else. I arrived at the hospital’s Digestive Endoscopy Center a little before my scheduled time. A nurse checked my ID and information, then gave me a hospital gown to change into—the kind that ties in the back. Once inside, the doctor and nurses were very friendly. They asked a few simple questions, like if I had any drug allergies or if someone was with me. In Spain, procedures like this are typically done under sedation, so you basically just sleep through it. A nurse inserted an IV line into the back of my hand, and then I was wheeled into the examination room. I lay down on the procedure bed, turned onto my side, and the anesthesiologist whispered ‘relájate’ (relax) in my ear. After that, I don’t remember a thing.
When I regained consciousness, I was already in the recovery room. I felt absolutely nothing during the entire procedure; there was no pain at all. When a nurse saw I was awake, she brought me some water and crackers and told me to rest. About half an hour later, once I felt fully awake, the doctor came over to explain the initial findings and gave me a preliminary report. The official, detailed report would be sent to my family doctor later. Because of the sedation, the hospital strongly requires that you be accompanied by an adult to leave, and you are not allowed to drive or perform any hazardous activities that day. My husband picked me up, and we went straight home. Apart from feeling a bit gassy, I had no discomfort whatsoever.
| Preparation Stage | Key Points |
| 3 days before | Start a low-residue diet |
| 1 day before | Consume only clear liquids and take the bowel prep solution on schedule |
| Day of procedure | Fast, and be accompanied by an adult |
Overall, my experience getting a colonoscopy at a public hospital in Spain was very positive. The medical staff were professional and kind, and the use of sedation made the whole process completely painless. So, if your doctor recommends this procedure for something like scheduling a colonoscopy in Spain, there’s really no need to be nervous. The most crucial thing is to strictly follow the doctor’s instructions for preparation, especially the bowel prep, as this directly affects the clarity and accuracy of the examination. I hope my sharing this has been helpful to you!
