Dr. Subramanyam Ayyar

Board Certified General Surgeon

NHSA / About Us / Dr. Subramanyam Ayyar

Meet Dr. Subramanyam Ayyar

Dr. Ayyar obtained a bachelor of science degree in biology from Baylor University and received his M.D. from the University of Texas Medical School in Houston, Texas. Dr. Ayyar completed his five-year residency curriculum in surgery at St. Joseph Hospital in Houston, Texas in 1999 with an emphasis in minimally invasive surgery. Aside from being a devoted physician, Dr. Ayyar is a loving husband and father of five.


Beyond the basic laparoscopic gallbladder removal procedures, appendix removal procedures, or anti-reflux operations, Dr. Ayyar also performs laparoscopic colon/rectal resections for infections and tumors, laparoscopic splenectomy, and adrenal and renal (kidney) resections. He has performed many laparoscopic hernia operations as well as single incision gallbladder removal, and robotic procedures.

While enjoying all aspects of general surgery he has pioneered minimally invasive surgical procedures in the suburbs of West and Northwest Houston. This form of surgery has evolved in the last decade and is advantageous for the patient, leaving smaller scars, less postoperative pain, and fewer wound infections affording individuals a rapid and safer recovery.

Dr. Ayyar and his partners have been successful in completing delicate operations endoscopically. Another field of his expertise is in the subspecialty of endocrine surgeries (thyroid, parathyroid, adrenal and pancreas). Dr. Ayyar combines his passion for minimally invasive surgery and endocrine surgery by performing thyroid and parathyroid operations through approximately an inch size incision.

More About Dr. Ayyar

Outside of the job, this hard working team of doctors enjoys volunteering at the Houston Food Bank during the holidays, helping to reach those who need it most across the city. With the support of his family and friends, Dr. Ayyar’s dedication and compassion is experienced by his patients and the community. He passionately loves what he does and it shows.

What Patients Say About Me

Dr. Ayyar, I feel so blessed and thankful to have found you in my time of need. Finding a doctor you can trust and believe in makes the decision and recovery 100% easier. Due to your great compassion for your work and patients, your extended knowledge and expertise in the field of cancer, I feel this robotics form of surgery could far exceed the more invasive surgery now practiced. It leaves no unsightly incision or scar, incurs less pain, has a quicker recovery and shorter stay in the hospital.
Sharon Clark, Pancreatic Surgery Patient.
Dr. Ayyar is an amazing doctor and surgeon. I cannot recommend Dr. Ayyar enough! I had virtually no pain a week after surgery with no scars. I highly recommend Dr. Ayyar to friends and family or anyone. If you’re trying to decide on your surgeon he’s #1!
