Palpitations after coffee or even chocolate?

[Toastandjams]

Hi, is it possible to get palpitations or fast heartbeat after eating chocolate which contains coffee?
A bit of my health history:
I usually can’t drink a coffee from Coffee shops like Costa or Starbucks as that is too strong for me, I always feel sick, heart pounding, dizzy.

I only drink now coffee at home, so I can see how strong Or weak I make it.
I am usually ok with those Nescafé sachets in a box, where is different flavours coffees like Irish coffee, Vanilla..
Anyway in this last month I had some stomach troubles like too much acid so I was taking Omeprazole for a full month- just stopped two days ago.
On Saturday and Sunday yesterday) I had my usual Nescafé sachet coffee and then later I had a few bars cappuccino chocolate bars from M&S ( I love these and never had problem with these)
As soon as I had the bars my heart got a such a bad palpitations and fast racing that I thought I’m having a heartbeat attack!
It lasted the whole Sunday( I had 3 of these chocolate bars)
It was a very unpleasant feeling, I could feel my heart in my stomach, ears..
at the evening I was ready to call Dr a I thought my heart is failing.
Than I check the wrapper of the chocolate bar and it says it contains real coffee.
Is it possible that I could be suddenly sensitive these chocolate?
I ate lots of these in a past and never had a problem!
I mean how much coffee it can be in a small chocolate bar?
Or the taking of Omeprazole maybe made me are too sensitive to it?
I have a leaky valves as for heart condition but don’t need follow up, as only minor..

I have leaky valves and only have decaf now as I had episodes over the past five years or so where after coffee or Coke my heart rate was close to 200. Can I ask how you know about the valves?

I had some palpitations about 6 yrs ago and GP sent me to Echo test.
That’s how they found it. Apparently 3 out of 4 leak but consultant said it’s no dangerous as lots of people have these without even knowing it.
I also had another echo test in 2018 and another consultant was not concerned. So no follow up.

But I can not have a normal coffee like even from coffee machine tassimo or Nespresso, these make me sick, dizzy, heart pounding..
As I said those Nescafé sachets are usually ok for me as I weaken it with milk..
but a choco coffee bar?

Coffee and chocolate both contain caffeine, the chocolate you've had will only contain a very small amount of coffee but that combined with the amount found in chocolate was possibly enough to trigger your palpitations.
I'd avoid coffee and potentially chocolate for a while, or switch to decaf coffee.
I'm quite sensitive to caffeine, can't drink normal tea or coffee (only have decaf) but luckily for me I am not affected by chocolate. I do avoid coffee flavoured / filled chocolates for that reason though.

Maybe try a small amount of non coffee chocolate to see if you are ok with chocolate normally?

@claireb707
Thank you.
I have to look into it.
As I said I had these chocolate bars in a past and never had problem, also cola is usually ok for me.
I was thinking maybe the Omeprazole made me so susceptible to it as had problem with my stomach lining as too much acid..

This morning I foolishly had a choco Moka coffee, which has low caffeine and my heart races again like yesterday..
oh god..

I think you're going to have to go with caffeine altogether, which I had to do. I started having side effects from caffeine a few years back which at first I could mitigate by mixing half decaf and half normal, but over time my sensitivity has increased so I just have decaf now.
And yes, dark chocolate and anything with real coffee in it has that effect.

I get palpitations/racing heart if I eat anything with high sugar in it. Even white rice causes me to have this. I sometimes get blood rushes at the same time.

Yesterday I had espresso martinis (2) in the afternoon. My heart was racing all night - I have had zero hours sleep.

I did go to the doctor years ago - I have a mitral valve prolapse (minor) but he didn't think it was serious, and I'm not sure that it caused the racing heart. He just told me to avoid eating that stuff! I love coffee (and today need it) but just avoid caffeine after about 11 am as I'm so sensitive to it. I avoid high sugar/carb stuff too.

I would to be on the safe side fine a very good decaff and switch to that.

I’ve had palpitations usually after a late coffee or too much sugar! Maybe it’s the sugar overload? I always get them when I’m overtired too.

Either way, you body is trying to tell you something, listen to it

My friend is the same. She was told to stop coffee and chocolate completely. She very occasionally has a ‘real’ coffee and a bit of chocolate and seems ok but daily coffee is off her menu.

I'm the same with caffeine, tea,coffee, energy drinks really make me feel unwell, like I've done cocaine or something! Then it gives me anxiety attacks, so I don't bother anymore x
