Medical Detection Dogs Help Diabetes Patients Regulate Insulin Levels

New research from the U.K. finds that well-trained alert dogs have the potential to vastly improve the quality of life of people living with type 1 diabetes.

As reported in PLOS One, on average trained dogs alerted their owners to 83 percent of hypoglycaemic episodes in over 4,000 hypo- and hyper-glycaemic episodes that were examined.

A hypoglycaemic episode is where blood sugar drops dangerously low and if left untreated, can lead to unconsciousness or even death.

The findings confirm that alert dogs can help type 1 patients regulate their blood sugars in a non-invasive way and avoid the risks of hypoglycaemic episodes and hyperglycemia.

“We already know from previous studies that patients’ quality of life is vastly improved by having a medical detection dog.” said lead author, Dr. Nicola Rooney from Bristol University Veterinary School. “However, to date, evidence has come from small scale studies. Our study provides the first large-scale evaluation of using medical detection dogs to detect hypoglycaemia.”

In this study, researchers from Bristol assessed the reliability of 27 trained glycemia alert dogs, whose owners provided six to 12 weeks continual worth of blood records detailing every time the dog was alerted.

Medical Detection Dogs train pet dogs to respond to respond to the odour of human disease and help owners live with life-threatening diseases. Familiar with their owners, dogs are conditioned to respond with alerting behaviours when their owners’ blood sugar levels fall outside a target range.

Encouraged by the alerting behavior of their pet dog, if such out-of-range (OOR) episodes occur, the patient can take appropriate action, usually by administering insulin or eating to retain the right glucose levels.

“Our research shows a dog’s effectiveness is affected by the individual dog and its connection with its human partner,”Rooney, added, “since the use of such dogs is growing, it’s important that any dogs used for these purposes are professionally trained, matched and monitored by professional organizations like Medical Detection Dogs.”

She says it’s also vital that research continues both to assess true efficacy and determine ways to optimize their performance.

“The findings are fantastic news for all those who are living with type 1 diabetes and other conditions,” says Dr. Claire Guest, CEO, and co-founder of Medical Detection Dogs. “Medical detection dogs primarily serve patients looking for more effective and independent ways of managing their condition.”

She says their dogs also serve the wider medical community by offering proactive solutions that are natural, non-invasive and have been shown to provide countless psychological benefits.

“As our natural companions, and with a highly refined sense of smell, why shouldn’t they be able to detect changes in our personal health?”

The research has been published in PLOS One.
