Could this be an anxiety issue? I have issues with my breathing going back to way before I started 5:2 - doctor gave me a leaflet on generalised anxiety disorder. Felt a bit embarrassed about it but I do find my job quite stressful.
Hi there, just noticed your post as I have experienced exactly the same..in fact this morning I posted the same question in the 5:2 diet forum. This was my first experience of prolonged palpitations (about 6 hours yesterday evening, it wasn't a fast day) Quite scary! I don't drink coffee, wasn't dehydrated...did you find out any more?
Has anyone else experienced this? Have had heart palpitations for about a month and one dizzy spell. Been on 5:2 in varying degrees of enthusiasm for about 6 months, on and off. I get the palpitations when I'm resting, not exercising.
Is it just me or is this a common side effect?
(btw obviously I've been to GP, had ECG which was normal, and waiting for blood results)
