The people we talked to had different ideas about what might have caused diabetes. Many believed that a family history of diabetes had predisposed them to the condition, others said it was caused by a combination of factors which included being overweight, being a heavy smoker or drinker, and not having done much exercise for years. Some people said that eating too much over many years hadn’t affected them until they became middle-aged and had stopped being so active. Eating too much of the wrong kind of food and ‘comfort’ eating were said by several people to have contributed to their diabetes (see ‘Food, Eating and Diet’).

Duncan thinks that his old habits of eating lots of takeaways and heavy drinking may have caused…

Eating too much of the ‘wrong thing’ such as food that was rich in sugar, salt, fats and having a habit of drinking fizzy ‘pop’ or fruit juice as opposed to water was also said by the people we interviewed to lead to diabetes. Eating sweets and sugar does not cause diabetes, but eating a lot of sugary and fatty foods can lead to being overweight, which is a risk factor.

Not everyone was interested in what had caused their diabetes and said that what mattered more was accepting the diagnosis and getting to grips with what it would mean for them in the long-term. A few people said they had no idea why they had developed diabetes and wondered if glandular problems or an unknown virus may have been responsible.

He feels resigned to having diabetes and prefers to focus on controlling it as much as possible.
