I am a patient of Dr. Saiful. First of all, I wanted to say that the way patients are admitted and the doctor visits in this hospital are very bad and rudimentary. I always arrive at 8 am and the staff says that there are 13 people ahead of me in the queue. I compare it to other hospitals and the way they are admitted is very bad,Every times must wasting time around 9 to 8 hours. Second :Comparing this hospital with a hospital like Thomson Kuta Damansara, we see that it is very weak‌ and hospitality is poor and price Range here more than everywhere .

I came to Malaysia with my mother for a health check-up from December 28th to December 31st. My mother has been suffering from diabetes for a long time, and her condition at the time was quite severe, with frequent shortness of breath, tremors, and extreme weakness. Walking even about 4 meters felt strenuous, so my mother spent most of her time in the car. I would like to express my deepest appreciation to the doctors and all the facilities at Gleneagles Hospital Kuala Lumpur, especially Dr. Mohamed Saiful Bahari Mohd Kassim, who treated my mother with utmost professionalism. Initially, I registered through IHH Center, but there was a communication issue. When we arrived at the hospital around 9:00 AM with our appointment confirmation, the appointment was not yet recorded in the doctor's administration. After a lengthy discussion, we were eventually given an appointment, but it was scheduled for the very end of the day, around 5:00 PM. On that morning, my mother had a blood test, and then we were asked to wait. Due to my mother's weak condition, we did not engage in much activity and simply waited for the subsequent examinations. We finally met Dr. Saiful around 6:15 PM, as he had a high volume of patients. Based on the blood test results, the doctor advised that my mother needed to be admitted for inpatient care that very day. I believe this decision was very appropriate and swift. During the inpatient stay, my mother was managed by three specialist doctors, including internal medicine, hematology, and gastroenterology. My mother also underwent a CT scan, and thankfully, the results did not indicate any other serious issues. Since her admission on December 29th until December 31st, my mother's condition has shown a significant improvement. Her breathing is more stable, tremors have reduced, and her overall condition is much better compared to when we first arrived. The service provided by the doctors, nurses, and administrative staff, as well as the condition of the rooms and hospital facilities, were excellent, clean, and professional. However, I also want to be honest and state that excellent service comes with a corresponding cost. For a 3-day, 2-night inpatient stay, the total cost incurred was approximately RM 20,000. Although it was a substantial amount, I feel the cost was justified by the results and my mother's significantly improved condition. I am writing this review in the hope that it will assist friends from Indonesia who are planning to seek medical treatment at this hospital, so they can prepare their finances, time, and mental state more thoroughly. Thank you, Gleneagles Hospital Kuala Lumpur and Dr. Saiful, for the invaluable assistance and care provided to my mother.
