I was recently admitted to the labour room 1 at Columbia Asia Hospital, and the experience was excellent. The ward and Operating Theatre (OT) staff were highly professional and hospitable. A special thanks to my anesthetist, Dr Loy, for the reassuring and wonderful care. Thank you to the whole team!

First of all, thank you so much to Dr. Raja Juhaidah, my O&G surgeon. From the very beginning, you made me feel like I was in good hands. Thank you for your reassurance, your kindness, and for making such a scary experience feel so much less overwhelming. Thank you as well to Dr. Loy, my anesthesiologist. I was really nervous before the surgery, but your calm and gentle words gave me so much comfort. surely will reduce my weight as per your advice hehe. A huge thank you to every nurse who looked after me during my 3 days and 2 nights in Ward MD3, Bed 81A. To all the day and night shift nurses, thank you from the bottom of my heart. Nursing is such a tough job, and after being a patient, I have so much more respect for everything you do. i forgot to ask for their names but some like Ms. Cynthia, Shahilla, and others... you guys are the best! I was in a lot of pain after my surgery, but every single nurse was so patient with me. they never made me feel like I was a burden. then nurse kept coming back to check on me, asked how I was doing, made sure my pain was under control, and guided me through every step of my recovery. also, a special thank you to the two nurses who helped remove my catheter. That was honestly one of the most painful moments for me, and I remember i couldn’t stop crying afterwards. Even though I don’t remember your names, I will never forget your kindness. You made me feel safe at one of my most vulnerable moments. One thing I’d really like people to remember is that patients like me only see these amazing nurses for a few days. We eventually go home, recover, and move on with our lives. But they stay. They continue caring for patient after patient, day after day, through long shifts, stressful situations, and emotional moments, yet they still greet us with kindness, patience, and genuine compassion. Thank you! :)
