‘Manju,
a 26-year-old IT professional working long hours in Kochi, developed
a nagging pain in the centre of her chest. She didn’t have the time
to consult a doctor, and so did what many people do in such
situations -- search the internet for a solution. Her Google search
left her convinced that all of her symptoms pointed to terminal heart
disease and that her days were numbered.
She
was no longer able to focus on her project, became irritable and
frequently showed up for work tired from lack of sleep. She was
already worried about how her dependents would cope with her absence.
Alarmed
at her change in demeanour, Manju's colleagues took her to a doctor.
After taking a detailed history including questions on her lifestyle,
her doctor ordered a couple of blood tests and told her that she had
acidity from irregular meal timings and excess consumption of cola.
Within two weeks, Manju was back to her cheerful, healthy self.
Manju’s
story is a typical case of 'cyberchondria', defined as the excessive
use of internet health sites that fuel health anxiety. The difference
between Google and doctor, in this case, was that while the internet
provided Manju with a long list of the possible diagnoses, the doctor
was able to dig out pertinent lifestyle clues from her history using
medical knowledge, correlate with the past experience of similar
patients, and arrive at a single diagnosis.’
This
is an excerpt from the article, ‘Who is better: doctor or Google?’
from the book, ‘Think Like Your Doctor’. It has been written by
the gastroenterologist, Dr Rajeev Jayadevan, the deputy medical
director of Sunrise Hospital. The book, which has been published
recently, has been received well. The writing is simple and
accessible, and the book makes for an easy read.
It
is a compilation of articles that Jayadevan had written for a
vernacular online platform. The subjects include memory loss in old
age, a user’s guide on painkillers, information overload, the truth
about cooking oils, and first-aid tips.
Meanwhile,
in his job as a gastroenterologist, Jayadevan sees a lot of liver
disease. And he is not surprised. Because a significant number of
Malayali men are heavy drinkers. “About 50 percent of liver
cirrhosis cases in Kerala are caused by drinking,” he says. “Many
of them are unable to stop drinking because they are addicted.”
And
the amount of money and effort that goes into the treatment, it ends
up devastating a family's finances. “It is a self-inflicted blow,”
he says.
When
he came to know that most had started drinking in their teens, he
started going to schools and colleges to urge them to stay away from
alcohol and drugs. This is what he tells the students: “I am not
here to tell you what to do. I am here to give you precise
information from my personal experience as a doctor about what
happens when you drink too much or take drugs. Now you can look at
this information and decide what you want to do.”
Through
his interactions, Jayadevan discovered the astonishing fact that the
average age when men start drinking is 13. “According to published
data, 25% of our high school boys are using alcohol,” he says. “It
is a major issue.”
Another
issue is the lack of exercise. Jayadevan knows of elite sportsmen in
college, who once they finished their studies, stopped exercising,
and became obese. “Their mothers want them to be fat,” he says.
“Society, too, wants them to become fat. As a result, by the time
they are 30, they have been diagnosed with diseases A, B, C and D.
These used to be diagnosed earlier at 50 and 60.”
Another
problem is that online users tend to believe everything that is
published on the Internet. “There are articles which state that
having garlic or ginger juice is good for health,” says Jayadevan.
“It might sound plausible, but there is no hard evidence to prove
it. People can be very gullible, but it can have devastating
consequences.”
Once,
there was a widespread rumour that the juice from the bilimbi
(chemeen pulli), which grows widely in Kerala, is good at reducing
cholesterol. Many people put a large quantity in the blender, made a
juice and drank it. Unfortunately, it was full of oxalate. “All the
oxalate clogged the kidneys and it shut down irreversibly,” says
Jayadevan. “Some were lucky to get a transplant, while others had
to go into dialysis for the rest of their lives.”
The
Kochi-born Jayadevan did his MBBS and MD from Christian Medical
College, Vellore in 1995. He went on to study Clinical Epidemiology
and Public Health at Erasmus University, Rotterdam, Netherlands.
Later, he was awarded the MRCP from the UK in 1996. He also
obtained Medicine and Gastroenterology (Fellowship) from New York
Medical College. Thereafter, he spent three years in the UK and 10
years in the US. As he wanted to take care of his ageing parents, he
returned to Kochi ten years ago.
Asked
whether he likes his medical job or writing, Jayadevan smiles and
says, “Both bring me joy.”
