Avoiding Weight Gain May Cut Costs For Diabetics, Finds Study

Even if one struggles with keeping your blood sugar under control, preventing weight gain is really important.

Overweight adults with type 2 diabetes who can maintain their current weight may reduce their health care costs in the long term, a recent study suggests.
From 2010 to 2013, researchers looked at whether maintaining weight, along with keeping blood sugar under control, had an impact on health care costs for people with type 2 diabetes.
The average patient in the study was obese. Even so, three years after the study began, those who maintained their weight had reduced their annual healthcare costs by $400 or nearly Rs 27,000, on average, regardless of whether their blood sugar levels were well controlled.

By comparison, those who gained weight and had uncontrolled blood sugar had an average cost increase of $1,473 or close to Rs 1 lakh.

“Simply put, weight gain is expensive,” said study co-author Dr Greg Nichols, a diabetes researcher at Kaiser Permanente Center for Health Research.

“Even if you struggle with keeping your blood sugar under control, preventing weight gain is really important,” said the doctor.

Almost 90 per cent of patients with type 2 diabetes are affected by overweight or obesity, the study authors point out in the journal Diabetes Care.

Using medical records of Kaiser Permanente members in the Oregon and Washington area, Nichols and colleagues tracked 8,154 adults with type 2 diabetes from 2010 through the end of 2013.

Overall, 81 per cent of participants gained less than 5 per cent of their weight, but only 38 per cent managed to maintain blood sugar control, as determined by the levels of hemoglobin A1c in their blood.

Patients who maintained their weight within 5 per cent of what it was at the start of the study had a reduction in costs of about $400 or nearly Rs 27,000 regardless of A1C.

Patients who didn’t maintain their weight had modestly increased costs if they were able to keep their blood sugar under control – about $387, on average, reflecting a 3 per cent increase – and a more significant increase in medical costs if their haemoglobin A1c levels were at or above 7 per cent. For that group, with weight gain and poorly controlled blood sugar, costs rose by $1,473 or Rs 1 lakh, on average, or 14 per cent.

Heart failure, depression and insulin use were also associated with greater health costs.
“Heart failure is a condition that requires constant hospitalization,” said Dr Amisha Wallia, an endocrinologist at Northwestern Memorial Hospital, who was not involved with the study.

“Preventing heart failure can impact the cost of diabetes,” she said.

She also pointed out how important it is for patients using insulin to pay close attention to their weight.

“Insulin can be very effective in bringing down blood sugar, but it can also cause weight gain. I tell my patients that we have to take this one step at a time – first we lower the blood sugar, then we address the weight,” she added.

Losing weight under any circumstances is difficult, noted Nichols.

“It’s not that blood sugar control isn’t important – it definitely is – but if your blood sugar is not terribly out of control, preventing weight gain may be a more important goal,” he said.
