I was diagnosed with type2 diabetes in 2012 and walked my first
Camino Frances in Nov13.
I did suffer a couple of hypo moments on first day from SJPP but responded with emergency chocolate.
I found myself desperate for sugar at various times. Resisted frequently, succumbed occasionally. But I did get through it.
I am not normally into salads but found myself desperate for healthy food, rather than the typical pilgrim menu and endless bread. So I did search out tomato salads and bean soups wherever possible.
As I got more used to the walking, I was able to leave behind the "emergency Fanta" and used the Acquarius soft drink. Still had some sugar but better by far than Fanta or Kas local equivalent.
Next time I aim to eat more rice and looking to cook it in thermos. Also looking to use more electrolyte replacement as I found I needed more than just water to manage my energy and morale. There were definitely times when my perseverance was challenged by low blood sugar, typically when not eating regularly and skipping breakfast through not being organised. Eventually I recognised that I needed a much better breakfast than typically available in cafe, so attempted to buy from shop night before and make something better than a pastry or a teeny sliver of ham in huge chunk of bread.
Much though I love Spain, it's culture, people and food, I came to despair of the bocadillo - what a culinary disaster !!
I continued to take tablets throughout. I didn't need insulin injections.
Unless you are quite high on blood sugar levels, you shouldn't have many problems with managing your T2 diabetes with some simple diet management. But don't trivialise or ignore it.
