India has 50 million diabetics and millions more in the pre-diabetic stage. T.V. Jayan sounds the alarm bells on the pre-diabetes wave that is about to engulf India | ||
It's just a sandwich, you told yourself, as you bit into the mayo-smothered chicken nestling between two slices of soft white bread. You watched your spreading waistline in the mirror — and promised yourself that one of these days you'd do something about it. And when the doctor told you to go join a gym, you yawned. There would be time enough for all this, you said. It's a story that may sound familiar to Chennai resident Sangeetha Raju. She's been there, done that — but wishes she hadn't. Last year, the 42-year-old banker had the chance of making an investment of her lifetime. She could have cut Rs 1,000-4,000 from her monthly expenses and saved herself some heartache. Raju was what doctors call a pre-diabetic — that is, her blood sugar level was above the normal, but not as high as that of a diabetic. Today she is a full-blown diabetic, requiring life-long medication — only because she ignored her doctors' advice. All she had to do was exercise for 30 minutes every day. But Raju thought pre-diabetic wasn't the same as a diabetic. Millions of people across India are making this mistake. A burgeoning population of young and middle-aged people has been diagnosed with borderline diabetes, a transition stage before full-blown diabetes, warns V. Mohan, head of Dr Mohan's Diabetes Specialities Centre, Chennai. People like you and me could be among them — the disease cuts across age, region, gender and class. Doctors warn that pre-diabetes is affecting not just those who have diabetes in their genes but even people with no such family history. Dropping levels of physical activity and wayward eating habits have together caused a diabetic epidemic in the country. And propping up this mountain are people like Raju, who could have walked away from the disease — but didn't. Geetanjali Shah, a 35-year-old Delhi psychologist, did that. A pre-diabetic, she was asked to reduce her weight by one-third to ward off the progression to diabetes. She ended up losing 30kg in five months. "She strictly followed 400 minutes of intensive physical activity per week, along with a strict diet," says her physician, Dr Anoop Misra, an internal medicine specialist at the Fortis Hospital in New Delhi. "Her pre-diabetes reversed to normal blood glucose levels." Her cholesterol and blood pressure levels — which used to be high before she started exercising — also became normal. If left unattended, pre-diabetic people run a high risk of developing diabetes within the next 5-10 years. That, in turn, can cause a host of ailments — including heart problems, kidney failure, damaged eyesight, erectile dysfunction and ulcers that can lead to amputation. The problem, doctors stress, is that few take borderline diabetes as a serious warning. "But the high prevalence of pre-diabetes may be a predictor of ominous things to come," says Nihal Thomas, an endocrinologist at Christian Medical College, Vellore. It may lead to a spurt in diabetes in less than a decade from now, he says. The actual number of pre-diabetics in the country is not known, but it is roughly 25-40 million — a huge worry for a country which already has more than 50 million diabetics. The latest Diabetes Atlas, released last year by the Brussels-based International Diabetes Federation, says that India will have 50.8 million diabetics in 2010. By 2030, the numbers will rise to 87 million. Borderline diabetes crops up in two forms — as impaired fasting glycaemia (IFG) and impaired glucose tolerance (IGT). In the first case, fasting blood sugar levels would be 100-126 milligram (mg) per decilitre (dl), whereas a healthy person's levels would be 70-100mg/dl. Those who suffer from IGT will have higher than normal sugar levels in the blood after a meal, though the levels wouldn't be as high as those with diabetics. Both indicate defects in the action or secretion of the hormone insulin whose primary job is to goad the cells in the liver, muscles and other organs to take up sugar in the bloodstream and use it as an energy source. The failure to do so means extra sugar in the blood, which translates into diabetes, a disease that often slowly kills. Of course, diabetes is often also genetic. If a person's parents are — or one of them is — diabetic, he or she is likely to become diabetic. But diabetes will probably come with the alarm bells — in the form of pre-diabetes. It is at this stage that people can make or break their future. For the disease can actually be checked in the pre-diabetes stage — and some believe it's the only way of battling the mounting diabetic epidemic in the country. What's interesting is that it's not difficult to do so. Many studies have shown that weight reduction through lifestyle modification and physical activity can reduce the risk of diabetes among the pre-diabetic population by half. "A mere 7 per cent weight reduction is all that is needed to cut the risk of diabetes by 58 per cent," says Mohan, quoting a landmark study by an international team which followed up 2,700 patients over up to 10 years and which appeared in the Lancet journal last October. Mohan's clinic has, interestingly, developed a simple scoring system called Indian Diabetes Risk Score, for those who have never had to undergo any blood sugar test. The do-it-yourself system, based on your age, waist circumference, physical activity and family history, tells you whether you are at risk or not (see box below). Losing weight and exercise help even those with a family history of diabetes. It's just that they have to work harder, says Misra. "Sometimes diabetes manifests even after taking all of these precautions. However, in most cases, it is delayed," he says. But pre-diabetics cannot wait and watch — as many tend to, to their own detriment — because the growing number of diabetics in the country is a cause for concern. The World Health Organization estimates that the economic burden of diabetes, heart diseases and stroke comes to about $210 billion in 2005. In India, people spend 2.5-15 per cent of their health budget on diabetes treatment alone. Thomas believes that nearly 10 per cent of India's adult population is pre-diabetic. The 2001 National Urban Diabetes Survey which covered six metros found that Hyderabad had the highest pre-diabetes prevalence at 29.8 per cent, followed by Chennai with 16.8 per cent, and Bangalore, 14.9 per cent. The study put the borderline diabetes prevalence in Calcutta at 10 per cent. Random studies in Bengal have shown that the prevalence of the most common form of diabetes in the state has gone up to 10-12 per cent versus 8 per cent about five years ago, says Ashok Kumar Jain, chief diabetologist at the S.K. Diabetes Research and Education Centre in Calcutta. Kerala — with a 19 per cent diabetic population, possibly the highest in the country —may also have the highest prevalence of pre-diabetes in the country. Mobile clinics conducted by Kesavadas Jothydev, who runs a diabetes research centre in Thiruvananthapuram, in Kerala have thrown up a scary picture. Up to 26 per cent of people in the 25-35 age group and 40 per cent in the 50-60 age group are pre-diabetic, he says. Public health experts are also worried that the scourge — once seen as a disease of the urban rich — is spreading to rural areas too. A recent study showed that 18 per cent of those below 30 years in urban areas of Vellore were pre-diabetic, as opposed to 14 per cent in the rural areas. A study in the Godavari region of Andhra Pradesh has shown that 14 per cent of its predominantly agrarian population is pre-diabetic, in addition to 13 per cent who already suffer from diabetes. The mechanisation of farm work — which means less manual work — is one of the reasons for the spread of the disease in rural India. Obesity is also one of the main factors responsible for pre-diabetes and diabetes. The Third National Family Health Survey conducted in 2006 shows that obesity has reached alarming levels in many states. Another study states that about 20 per cent of Indian school children are obese. And many of them, clearly, are going to be pre-diabetics sooner rather than later. When it comes to obesity, the odds are already stacked against Indians. Studies have shown that people in the sub-continent put on more fat around their abdomen than those in the West. The increased body fat leads to greater insulin resistance in Indians, says Dr Seema Gulati, dietician at the Diabetes Foundation of India. Clearly, Indians have to strive that much harder to ward off diabetes. And they'd better swallow the bitter pill — without a sweet coating. |
