Birthdays, weddings, Christmas and other special occasions and religious holidays all bring different eating patterns and unusual food; and often quite a lot of it!
Similarly, some religions have periods of extended fasting, like Ramadan and Yom Kippur. Although fasting is not compulsory where it may risk health, some people with diabetes do choose to observe the ritual, increasing their risk of hypoglycaemia, or DKA and dehydration if they do not take their medication.
There is no right or wrong approach, just what works for you. You may need to be a little flexible – accepting a slightly elevated blood glucose reading at a feast, or treating a hypo during a fast – or simply choosing to mark these occasions in different ways.
The most important thing when facing either situation is to discuss it with your healthcare team in advance and have a plan, and also not to beat yourself up if the day doesn’t go according to that plan.
Diabetes UK has more information on fasting, and here is a blog from Nadeem Masood about how he approaches fasting.
