I recently had a colonoscopy at a public hospital in Spain, and the process was much smoother than I expected. I decided to write down my whole experience as a reference for anyone who might need it. After all, your health is your wealth, and regular check-ups are crucial.
Appointment and Preparation
It all starts with your family doctor (médico de cabecera). I’d been feeling some discomfort in my stomach, so I made an appointment. After I described my symptoms, the doctor thought a colonoscopy was necessary to rule out any issues and gave me a referral to the hospital’s gastroenterology department. I was put on a waiting list, and about two months later, I received a letter from the hospital with the specific date and time for my procedure. It also included detailed preparation instructions for seeing a doctor in Spain and a box of bowel prep medication.

The Unpleasant Bowel Prep Phase
The most important part before the procedure is the bowel prep. This step is absolutely crucial as it directly affects the quality of the examination. Following the instructions, I had to start a low-residue diet three days prior. This basically meant white bread, white rice, chicken breast, fish, and the like, while avoiding all fruits with seeds, vegetables, and whole grains. The day before the procedure, the “epic” laxative-drinking phase began. I was given two bottles of solution to drink in two doses. The taste was… hard to describe, a bit salty and a bit sweet. I just had to pinch my nose and chug it down. After drinking it, I was constantly running to the bathroom until my output was clear liquid, which meant the prep was successful. This process is quite exhausting, so I highly recommend taking the day off work to rest at home.
Procedure Day Walkthrough
On the day of the procedure, I went in on an empty stomach. You need to be accompanied by an adult because you can’t drive or go home alone after anesthesia. At the designated area in the hospital, a nurse first verified my information, then led me to change into a gown and inserted an IV catheter into my hand for administering the anesthetic. The medical staff were all very friendly and chatted with me to help me relax, which was very reassuring; it’s great to have such positive experiences with the healthcare system, whether for this or a simple [scalp examination]. After that, it was just a matter of waiting to be called into the examination room.
| Preparation Phase | Key Tasks |
| 3 days before | Start a low-residue diet |
| 1 day before | Take bowel prep solution as instructed, no solid food |
| Day of procedure | No food or water, be accompanied by a family member or friend |
Anesthesia and the Experience
When it was my turn, I was led into the examination room and asked to lie down. The doctor and nurses were all there. The anesthesiologist asked a few simple questions, like my weight and if I had any allergies, then administered the drug through my IV. I just felt a cool sensation in my arm, and then… nothing! I was out in a second, I didn’t feel a thing. The next thing I knew, I was in the recovery room. The whole thing felt like I just had a nap; it was completely painless. When a nurse saw I was awake, she gave me a glass of juice and some cookies to regain my energy. A little later, the doctor came by and told me the results were all normal and there was nothing to worry about. A huge weight was lifted off my shoulders. The entire process, from entering the examination room to leaving, took only about half an hour. Overall, the colonoscopy in a Spanish public hospital is very reliable. Apart from the slightly long waiting time for [hospital tests in Spain], the experience was great, so there’s no need to be overly nervous or scared.
