Blood thinners and diarrhoea

Broseley profile image
52 Replies

Hi, I've been on blood thinners since about 2012. I have had slowly increasing problems with morning diarrhoea since then. I was on apixaban but was changed to edoxaban for safety reasons on the advice of the GP's pharmacist. No change noted. I've been trying to track down the cause of my diarrhoea, and the only pattern I can find is it occurs most when I move more. So this affects my weekly shop on a Wednesday morning but always when we're on holiday, and at weekends when I'm out more.

I learnt today from my cousin that she also had daily diarrhoea after being prescribed blood thinners. She tried every type, no difference, so she stopped them, for quality of life. The diarrhoea stopped and she's had no more problems since.

Has anyone else made this connection?

I'm on blood thinners for suspected AF which has never been confirmed. I have never had any symptoms, just a 1 second glitch on an ECG which was suspicious of AF. A Holter monitor for a week failed to confirm it, yet they still want me on blood thinners!

Hi Brosley.

Yes, it can and does happen. I have quite a good link to this but the new forum rules won't allow me to post it.

Google 'Blood thinners and diarrhoea'. You'll soon find it it. (MedinePlus).

Read the post quickly before it's deleted 👍

Thanks. I was wondering if anyone else on this forum has had this issue?

Actually Paul, I sometimes wonder if these forum rules would tend to make the forum increasingly irrelevant nowadays. Anything useful, as is your comment, I tend to 'Screenshot' it immediately in case the thought police nobble it. Then do my own research independantly later.

It depends which particular forum it is. I think they're all moderated by their own people. I'm on the PMR forum and they allow links to be posted.

Paul,

What's the point of life (or even this Forum) if you can't say what's in your heart.

Take heart and publish the link young man (as Brian Clough might have said!) ... and perhaps add the following words at the end of your Reply (as previously suggested to me by Admin) ...

"Warning from Admin:

If anyone has any questions regarding the article and how it may apply to them to please speak with their doctor or healthcare professional for advice".

Hi Bob.

I'll play it by the rules although it is a little frustrating. What if I wanted to reply to a post now and include a link? At this time I wouldn't get approval until tomorrow would likely not bother replying to the post.

Paul

ozziebob in reply toPaulbounce

Exactly, the Forum is now full of frightened members too scared to post honest information and then making pathetic excuses for their reticence.

Publish and be damned!

Better to die honourably than live in fear as many on the Forum now seem to have chosen.

It's Medline Plus. But all it says is that diarrhoea can be a side effect.

I know that anticoagulants can cause gastro problems in some people. I’m curious as to why you’re on them if Afib has not been confirmed, but presumably your doctor considers you to be in a high risk group - maybe family history, age, other heart condition? If I was you I’d seek a second medical opinion.

Broseley profile image
Broseley in reply toRainfern

It was the cardiologist at the hospital. I think they're covering their backs, that's all.

They have to go by NICE guidelines.

Yep, had two years of misery on Warfarin with severe diarrhoea but couldn't get the medics to take it seriously. As a result, I developed hemmeroids, which still cause me problems. Eventually persuaded them to switch me to Apixaban and that solved the problem. Been on Apixaban for about two years now without any problems.

Broseley profile image
Broseley in reply toBrotherThomas

I was on apixaban, now on edoxaban. No difference.

Sunnyday2022 profile image
Sunnyday2022 in reply toBrotherThomas

That is very helpful to me so thank you. I was put on Edoxoban a few months ago and have had nothing but problems with my digestion since. Acid reflux (despite being on Lanzoprazole) and frequent bouts of diarrhoea which have also caused haemorrhoids! My GP was very sceptical that any anticoagulant would cause digestive issues so hearing that someone else has had problems is useful. Going to see cardiology tomorrow actually so will ask if I can change to something less likely to cause problems.

BrotherThomas profile image
BrotherThomas in reply toSunnyday2022

Yes, I think you have to stand your ground and insist that they give you something else. Beware of being fobbed off with a P P I, proton pump inhibitor, such as imaprazole, which are prescribed for diarrhoea and excess acid. Despite being prescribed for that, diarrhoea is a known side effect of them and people can suffer other problems when they stop taking them. Good luck.

Broseley profile image
Broseley in reply toBrotherThomas

I was put on omeprazole when I started on steroids for PMR. They insisted on it. I did try stopping them for a few weeks to see if it helped my diarrhoea, but it didn't.

I have experienced this, and it is always important to ensure you have the anticoagulant dose with plenty of food.

Broseley profile image
Broseley in reply toStato308

Thanks, I take mine about 20 mins before breakfast. The diarrhoea starts about half an hour to an hour after breakfast.

I too have had changes in bowel habits since I was diagnosed and started meds. I had assumed it was a change in my bp meds, but maybe I was wrong.

I have detected afib with a Kardia Mobile. Cardiologists have not managed to after running 2 holters each for a week.

However I am on edoxaban. Initially I tried Rivaroxaban but 3 weeks later I had bad lower GI pain which kept me awake at night. I changed to Apixaban, then warfarin, and now edoxaban, but the pains persist.

I cannot attribute them to anything other than the anticoagulants.

I have no solutions, but it's clear to me that for some people blood thinners cause gastric problems

Hi Brosley,

I have confirmed Paroxysmal AFIB, my chad score is 0, so no Blood Thinners.

I am not giving you medical advice, but if I were you I would have a long talk with your EP about why you are on blood thinners.

I take two aspirin during an AF event. Nothing otherwise.

Broseley profile image
Broseley in reply toAustinElliot

What's a CHAD score please? I've never had an AFib event, though apparently they are not all evident. My Fitbit has never detected anything either.

AustinElliot profile image
AustinElliot in reply toBroseley

Hi Brosley,

CHAD score is your risk of a stroke, its best if you google it.

However, again I am not a doctor and don't know your full medical, but in my opinion it is highly suspect (verging on malpractice) to have prescribed a blood thinner for you when you 1. Don't appear to have had an AF event in 11 years, 2. Were never conclusively diagnosed with AF.

Most people on this forum have official diagnosis (Doctor Ekg, holter monitor, ER room visit), or have a device that can determine they are having an AF event (i.e. an apple watch or kardiamobile)

Some folks won't take a blood thinner even with a higher CHAD score, right or wrong.

But in your case you need to find out why your doctor put you on blood thinners (this does not prevent AF, only the 'risk' of stroke during/after an AF event.

Good luck

(there are others on this forum that have a better grasp on the risk/rewards of blood thinners for folks diagnosed with AF)

Broseley profile image
Broseley in reply toAustinElliot

Thanks. I think CHAD is not used in the UK. It was not my GP who prescribed blood thinners etc but a cardiologist via a letter with results of a Holter monitor that picked up a 1 second glitch "suspicious of atrial fibrillation". The follow up Holter test 5 years later picked up nothing over a week but the cardiologist, a different one, said to continue on blood thinners anyway. GPs here in the UK are pretty clueless in my experience and always refer you elsewhere!

Redactrice profile image
Redactrice in reply toBroseley

Hello there. CHADs is absolutely used in the UK (my score is 1, only because I'm female). I've had lone paroxysmal AF for 12+ years (formally diagnosed 12yrs ago), and every time I encountered a GP in the early days they'd panic and say 'You need to be on blood thinners!' All four of the cardiologists I saw in that time frame agreed with each other and with me that I did NOT need to be on blood thinners because I was at relatively low risk of a stroke (CHAD score). The consensus was that 'blood thinners are nasty and you want to avoid them until you really need them', which unfortunately is now (probably in persistent AF since I had Covid last May...still waiting for cardioversion...now taking daily drugs for the first time in 12yrs, alas). Do investigate with a cardiologist. Good luck.

As for diarrhoea, yup, I've never had the squits so much in my life as I have since I began taking daily rivaroxaban/Xarelto three months ago. I divide my dinner and take the rivaroxaban approx halfway through so that it isn't hitting an empty stomach and is still accompaned with food going down (to minimise heartburn, which I'm also having for the first time in my life -- bad enough to wake me up; I hope it's gastric, not cardiac!). Several times a week, between 90min--2hrs after eating and taking the dose, I'm doing the quickstep to the toilet, often several times within the next few hours. Oh joy.

Broseley profile image
Broseley in reply toRedactrice

You poor thing! I am convinced it's the blood thinners causing this. The gastro consultant pooh poohed the idea and said it must be diet. I take omeprazole because I'm also on steroids for PMR though I've also never had any issues with acid reflux.

Cavalierrubie profile image

l would not be happy with that diagnosis. I cannot tolerate any of the new anticoagulants and as a last resort had to go on Warfarin, which l just manage to tolerate. You could of just had an ectopic cluster picked up on your ecg. You need to get yourself a monitor. My blood pressure monitor tells me when l am in AF. A heart symbol appears, but l can also feel my heart in my chest going all over the place. I suppose they were being cautious putting you on anticoagulants, but you will probably feel much better if they are not necessary and stopped. I think a firm discussion with your GP/EP is needed. All the best.

Broseley profile image
Broseley in reply toCavalierrubie

Thanks. My Fitbit has never detected AFib, but the GP put that down to the meds I'm on - edoxaban and bisoprolol. Though only 1.25mg of the latter at my request because it lowered my heart rate too much and made me feel sluggish. I didn't think the AFib could be prevented by these meds?

One GP said "You can stop blood thinners if you want". But the cardiologist letter said to stay on them so if I stop them, then have a stroke it's my fault not theirs.

Cavalierrubie profile image
Cavalierrubie in reply toBroseley

I know it’s difficult for you being in this situation but you haven’t had an accurate diagnosis which is very worrying for you especially being given all these drugs. The meds you are on don’t always stop AF. You are between a rock and a hard place. I can’t take Bisoprolol regularly as it lowers my blood pressure too much and also made me very ill with the side effects. I use it as a PIP. I really don’t know what to advise you to do as it’s your personal decision and you have probably been scared by it all, l know l would be. I hope somewhere along the line you are able to catch this monster, if you have it, and either way put your mind at rest. I really didn’t think they would put someone on these drugs unless an accurate diagnosis was obtained as we are not talking about sugar pills. Hope it works out for you soon.

Broseley profile image
Broseley in reply toCavalierrubie

Thank you gor your encouraging words. I'll definitely look into it.

Redactrice profile image
Redactrice in reply toBroseley

Bisoprolol had the same effect on me. It turned me into a zombie even at that same very low dose (1.25mg), because they made my normally lowish heart rate drop much too low. For that reason, I abandoned bisoprolol after six weeks with my regular cardiologist's approval. But that was several years ago when I was only having very occasional paroxysmal AF, like once or twice a year, never lasting longer than 12hrs. If your episodes are similarly infrequent, I'd question with a cardiologist (not a GP) whether you really need daily BBs.

Due to being in persistent AF I'm now stuck with 25mg metoprolol twice a day. I'm not a complete zombie (because my heart rate is higher than normal due to being in persistent AF), but I've been told by others that BBs 'make it hard to get out of first gear', and that is definitely true for me.

Broseley profile image
Broseley in reply toRedactrice

I have never had an episode, to my knowledge. I do get palpitations which respond to vagus nerve stimulation, and ginger pills so I think that's gut related too.

marcyh profile image

I read this with interest. I'm on Apixaban (5 years) and am slowly developing problems. It is also diet related but I have to wonder if my anticoagulant has anything to do with it.

Broseley profile image
Broseley in reply tomarcyh

That's what this forum is for, glad you found it useful. I hope your problems get sorted. My gastro consultant told me to try the low FODMAP diet, but I'm dubious as I know some things on it disagree with me. But something is causing me to get high levels of inflammation in my colon, as a calprotectin test showed. Funny too, how it always happens mornings only, after I've taken my pills.

marcyh profile image
marcyh in reply toBroseley

My doctor gave me the FODMAP diet too and much of it wasn't useful. We all different and we have to keep experimenting. I journal daily to help understand what the triggers are but it's not consistent. I've started taking as many pills and supplements as I can with food.

Broseley profile image
Broseley in reply tomarcyh

Yes, I do too. I recently started on aloe vera which is supposed to help with gut inflammation.

Redactrice profile image

Just this week I learned that there are slow-acting (once a day) and fast-acting (twice a day) blood thinners, and the slow/once a day doses are not diet-dependent like fast/old style blood thinners. I had been wondering why I was given no dietary advice when I began taking rixaroxaban/Xarelto -- this is why (and have yet to be called in for blood test monitoring in the 90 days I've been on it?) .

It came up in a completely different context so I'm going to start another post about it.

Broseley profile image
Broseley in reply toRedactrice

Interesting. I was put on apixaban which is twice a day, no dietary advice. Then put on edoxaban which is once a day. I was told that edoxaban is safer if you miss a dose. I presume then that edoxaban is slow acting? It's made no difference to my diarrhoea problem though.

I had to cease NOAC medication because it had such a toxic effect on my IBS-d symptoms. I'm afraid gastric tract trauma is a very common side-effect with these drugs. You have to make a personal risk assessment about gastric bleeds and diarrhoea and stroke risk during AF attacks.

Hi Brosely,

I have diarrahea with my blood thinners and my doctor recommended that I take Florastor and it works.

I hope this helps.

Linda.

Thanks, just had a look at them. They are £241 on Amazon UK. A bit pricey! Why can't you get them on prescription if doctors are recommending them?

Hi Broseley,

In Canada, it is not that expensive to buy it. Maybe you should ask your doctor for the prescription.

Sorry.

Brosley. Have you considered natural blood thinners? That's all I take since 2015.

See one of my replies here:

healthunlocked.com/afassoci...

Nattokinase is my primary thinner, enhanced by Vitamin "E", "D3" and Turmeric.

Plus, no side effects that I know of. Good luck.

Broseley profile image
Broseley in reply tosolarjdo69

Thanks, I already take turmeric. I didn't know it can be used as a blood thinner. I also take D3 as part of Calci-D for osteopenia. I'll look up nattokinase.
