Hi Simon from a fellow Type 3c, distal pancreatectomy, splenectomy and gall bladder whipped out! All this happened 11 and a half years ago. I didn’t go away for about 16 months after my op, I just googled travel insurance for pre existing conditions then I called them didn’t try and do it on line. I obviously told them everything but because I didn’t have cancer ( my tumour, thankfully, was pre cancerous so no treatment needed) and my spleen had been healthy before they removed it, just in case, I was covered. I don’t remember how much it was but if it had been extortionate I would have remembered! After 2 years it gets easier and cheaper my last trip abroad in March to Portugal for 8 nights cost me £8! I don’t have any diabetic complications haven’t seen a doc about my pancreas ( or the bit I have left) for donkeys years. All insurance companies will cover you but at a cost. Do not EVER think about not declaring anything, I was a travel agent in another life and have seen the consequences of this. Hope this helps.
