A case study:
I myself Chaitanya Gupta, a 11 year old boy would like to tell the whole
world that I am thankful to Dr G.D Oswal and his G-Therapy. I was suffering
from autism spectrum disorder. Now I am confident as normal person and I am
not afraid of the world.
When I was just three months old baby, I suffered from severe illness and
was having frequently high fever. Every time, my mother took me to doctors,
they prescribed higher dose of antibiotics. But the fever was not getting
controlled and each time the antibiotic dose was higher than previous one.
This resulted in my brain development and at the age of three I was
diagnosed with autism at a reputed hospital in Mumbai. While going thru a
year of treatment with Hinduja hospital at Mumbai, my mummy came to know
about Dr. Gunvant D. Oswal through a friend.
Then in august 2001, we got our first appointment with DR. G.D. Oswal and my
treatment was started.
Initially my immunity system began to develop and without any high dose of
antibiotic, my fever became normal. That was the first sign of the
improvement.
Even at the age of 4-5 years, I was not talking much, I would just repeat
words or rather answer irrelevant answers or tell them some long time back incidents like road accidents. Everybody around me would just laugh at my irrelevant answers . I could not sit at one place for a single minute. I was hyperactive. Even
while playing, talking, I kept moving or shaking my hands or leaping. I
could not sit still for a moment.
After recovering from high fever, I was free from high doses of antibiotics
and then processing of my normalization began.My talking skill improved, my
parroting attitude changed to answering people's question instead of telling
past stories and giving irrelevant answers. I would answer them properly.
Slowly my talking skill also improved. In just few words I used to describe
things and stories. I began to sit still for some time and now I am no
longer hyperactive.
Today after seven years of treatment, I am fine and more like anybody around
me. I'm confident and score good marks in school. I'm in normal school
and studying in class VI. I play football and do judo. I like to play music on
keyboard. My parents are happy too. They all thank Dr. Oswal for all these.
