Dr Vadamalayan is professional and caring. My son has been under his care for 3 years during which time we have seen significant improvement in his condition (of Crohns) such that he leads a fully normal life. We have been provided with clear information and instructions. He responds quickly to correspondance, and the administration from his office is exemplary. We are extremely grateful.

We consulted Dr Babu for my son with history of abdominal pain and bleeding . Doctor Babu listened to us, and after careful examination recommended further tests. He performed endoscopy and diagnosed colitis , and treated with medication. We are very pleased with his support and highly recommend him.

Our one-year-old daughter needed an MRI and an gastroscopy,, both of which required general anaesthesia. We asked Dr. Vadamalayan if they could be performed together so she would only need to undergo general anaesthesia once. It was very difficult to arrange this, but Dr. Vadamalayan truly did his utmost and managed to get both procedures done in a single session

We were referred by our insurance, and Dr Vadamalayan helped to manage my son’s abdominal pain. He diagnosed H pylori gastritis and treated successfully with an improvement in symptoms. He did not put us through unnecessary investigations and always explained well & discussed the management plan with us in detail

Unfortunately, I'd not rate Dr Vadamalayan highly. My child and I were in and out in 10 minutes and I felt that he didn't listened to me much or took any notice of what I was telling him, even before we left the room he was checking his phone. Even my child commented " that was quick mummy, it took us 25 mins to get here and only a few mins to see the doctor!" Despite telling the doctor that my child did not suffer from constipation he prescribed tablets for a colonic transit study so my child had to take tablets for 3 consecutive days and on day 4 an x-ray of abdomen was done. He called us a couple of days after the x-ray, he didn't even have the results and asked us to tell him once again what our concerns were which I thought he'd have had noted down during our initial consultation. He then called a few days later to tell me that he had found the x-ray results and there was no sign of the tablets somy child did pass them and didn't have constipation which I had told him already. The only thing he could suggest was giving my child laxatives to make my child have diarrhea and clear out the intestines which again was unnecessary as the reason for our visit was to find out why my child throws up occasionally while feeling absolutely fine and well, without any sign or symptoms of any illness. My child did not suffer from constipation. I told him at the consultation that it could of course be psychological but I wanted to rule out any physiological problems and focusing on constipation was not helpful. Having had to pay the excess on our health insurance and other bills I'...

I highly recommend this doctor and he diagnosed reflux on our 8 weeks old. He did not recommend to exclude milk unnecessarily like 2 previous doctors and discussed the rationale for the treatment plan at every step
