Diabetes UK: Survey reveals hidden incidence of "hypos" among people with Type 2 diabetes

Survey reveals hidden incidence of "hypos"
among people with Type 2 diabetes

"Total confusion. vulnerable. frightening.
unable to function in a rational manner"* 1

Half (49 per cent)1 of people with Type 2 diabetes2 (excluding those treated with insulin) experienced at least one "hypo"3 - an episode of low blood glucose that can result in symptoms ranging from sweating to a loss of consciousness - during a fortnight period4, according to a new survey by leading health charity Diabetes UK.

Sponsored by Bristol-Myers Squibb (BMS) and AstraZeneca (AZ)5, the survey questioned 1,954 people with Type 2 diabetes in the UK and provides insight into the prevalence and impact of mild to moderate hypos.

Over half (52 per cent) of those surveyed believe mild to moderate hypos affect their quality of life and one in ten reported having to take at least one day off work in the last year as a result of a mild to moderate hypo1.

Simon O'Neill, Diabetes UK Director of Care, Information and Advocacy, said: "Previous research around hypoglycaemia has tended to focus on the impact of severe hypoglycaemia. This survey, however, reveals the everyday impact of mild and moderate hypos among people with Type 2 diabetes."

"Importantly, this survey has also shown us that even people who are not taking insulin are having regular hypos. These people need to be reassessed by their GP to ensure they are taking the appropriate medication.

"Almost 90 per cent of people with diabetes in the UK have never received structured diabetes education6, which is key to improved self-management and a reduced risk of hypoglycaemia. It's therefore vital that we make this area a priority for improvement. We want to see hypos become the exception rather than the rule."

The survey also revealed that more than one third reported that mild to moderate hypos affect their ability to carry out day-to-day tasks, including housework (35 per cent), social activities (37 per cent), sports activities (35 per cent) and sleep (35 per cent). Nearly half of those questioned said they worry about having a mild to moderate hypo (47 per cent) and that their emotional wellbeing is affected (47 per cent) 1.

Type 2 diabetes is treated with a healthy balanced diet and regular physical activity, but medication is often also required. Hypos only occur in people with Type 2 diabetes who have to take certain medications. Treating a hypo is usually simple and requires taking some fast acting carbohydrate, such as a sugary drink or some glucose tablets, and following this up with some longer acting carbohydrate, such as a cereal bar or sandwich3.

Tim Page, 53, from Wadhurst, East Sussex, was diagnosed with Type 2 diabetes in November 2003. He said: "I experience hypos fairly regularly, most of which are mild but nonetheless have a huge effect on my life.

"Even the mildest of hypos can leave me feeling weak and disorientated, very tired - in fact, exhausted.

"This is followed by what I can only describe as a real hunger pang, so simple day-to-day things that most people take for granted, like driving or looking after your children, sometimes even going out for a walk, can be difficult for me and mean I've always got this nagging fear at the back of my mind."

1Results of a Diabetes UK online survey of 1,954 people with Type 2 diabetes in the UK, conducted between 15 June and 13 July 2009, sponsored by Bristol-Myers Squibb and AstraZeneca.

2Type 2 diabetes develops when the body can still make some insulin, but not enough, or when the insulin that is produced does not work properly (known as insulin resistance). In most cases this is linked with being overweight. This type of diabetes usually appears in people over the age of 40, though in South Asian and African-Caribbean people it often appears after the age of 25. However, recently, more children are being diagnosed with the condition, some as young as seven. Type 2 diabetes is the most common of the two main types and accounts for between 85 and 95 per cent of all people with diabetes. There are currently 2.5 million people with diabetes in the UK and up to half a million people with diabetes who have Type 2 diabetes but don't know it.

3Hypoglycaemia (or a 'hypo') occurs when the level of glucose in the blood falls too low, usually under 4 mmol/l. People with diabetes who take insulin and/or certain diabetes tablets are at risk of having a hypo. A hypo may occur if you have taken too much diabetes medication, delayed or missed a meal or snack, not eaten enough carbohydrate, taken part in unplanned or more strenuous exercise than usual, and have been drinking alcohol without food. Sometimes there is no obvious cause. When a hypo happens the person often experiences 'warning signs', which occur as the body tries to raise the blood glucose level. These 'warning signs' vary from person to person but often include feeling shaky, sweating, tingling in the lips, going pale, heart pounding, confusion and irritability. Treatment is usually very simple and requires taking some fast acting carbohydrate, such as a sugary drink or some glucose tablets, and following this up with some longer acting carbohydrate, such as a cereal bar, a sandwich, piece of fruit, biscuits and milk or the next meal if it is due. If left untreated the person might, eventually, become unconscious and would need to be treated with an injection of glucagon (a hormone that raises blood glucose levels). But in the vast majority of cases the body will release its own stores of glucose and raise the blood glucose level to normal, though this may take several hours. Many people have hypos while they are asleep and come to no harm. However, being unconscious is always dangerous - for example, especially if you are driving and because of the risk of choking. An ambulance should be called immediately if someone with diabetes is found unconscious. You should never try to put food or drink into the mouth of someone who is unconscious. Hypos can be particularly dangerous following alcohol. If you have a hypo after drinking, the body is less able to release stored glucose and the blood glucose level may fall dangerously low. It is recommended that people on insulin should not drink more than three units of alcohol for a man or two units for a woman per day, and that you should always eat when you are drinking and have a bedtime snack, to lower the risk of a hypo.

5The Bristol-Myers Squibb and AstraZeneca collaboration is delighted to have supported Diabetes UK by sponsoring the development and implementation of its online survey investigating the impact of hypoglycaemia among people with Type 2 diabetes. Formed in January 2007, the Bristol-Myers Squibb and AstraZeneca collaboration is dedicated to patient care, improving patient outcomes and creating a new vision for the treatment of Type 2 diabetes. This includes the discovery and development of effective treatments that help to reduce the risk of developing the complications associated with Type 2 diabetes and enhance the lives of both individuals with diabetes and their families.
