diarrhoea after each exertion

Hello,
for some weeks now I started to have always diarrhoea after each exertion.
I used to dring some choco cow milk + whey after my ride
I tried to replace cow milk by soy milk to see if something changes, but it does not seem to have an impact.

I tried alors to replace my sport drink home made with fructose by another with only simple sugar like dextrose, again does not seem to work

Someone has an idea, or has already experienced that ?
Is it simply a sign of too much training (i almost train every day, about 40 miles by day)

Enzo

Whatever is causing your discomfort, assuming it occurs right after riding, it's probably not what you drink after the ride. It would take several hours, at least, for that to cause problems.

If you can drink plain water during your ride without discomfort, try diluting your sport drink more and see if that is tolerated.

I've had this happen when I work very hard and drink either plain water OR full-strength Gatorade. 1/3 strength Gatorade works ok, but doesn't provide enough electrolytes for me. Have ordered some HEED to see how that works.

I think the seating position and constant movement just favours gastrointestinal motility in some people. A friend of mine has the same problem, but not diarrhoea. You may in fact by consuming too much fluid as your body cannot reabsorb enough by the time it reaches its end point.
Kudos to you though on your training, its intense.

yes, perhaps I am drinking to much as I weight more after my ride than before.
perhaps it is the key.
the diarrhoea appears several hours after the ride

Well, that is typically caused by malabsorption of some sort.

Fructose is a poor choice for sweetener for a sport drink. Unlike other sugars - which can be absorbed fairly rapidly - fructose can only be absorbed at a slow rate, and if you take in too much, it gets beyond the part of your GI tract where it can be absorbed. Different people have different responses to fructose - I'm really sensitive to it, and having any of it during ride makes me feel sick within a few minutes.

It could also be the water you mention - if you drink enough to feel sloshy - though that generally doesn't cause those sorts of symptoms.

Oh, and one other thought - if your homeade drink doesn't have any salt in it, that will also limit absorption.

So, my advice is:

1) Try a commercial drink, and see how that works for you.
2) If you're doing your own drink, make sure it has salt in it (say, 200mg/liter)
3) If you want to use fructose, use it with perhaps a 50/50 mix on some other sugar.

Hey, if I drink ANYTHING with whey in it, I'm racing to the bathroom.

Lot's a people have lactose or wheat, barley, or whey intolerance.
I would try a different drink, I'm betting it's the whey / milk combo.

after a bout with diarrhea, time to rebalance and get your body back to normal. Try Pedialyte. Get on Google and try "pedialyte ingredients"

You can still have problems even without wheat, barley, rye, or milk products in your diet. I have celiac disease and lactose intolerance and still can get diarrhea without being infected with a gastro-intestinal bug. All it seams to take is excess fluids and vibration while sitting upright.

+1

pedialyte is much better if you're having gastrointestinal problems. i think it's the sugar in gatorade/sport drinks that upsets stomachs. and also, physical activity draws blood from your GI tract to your peripheral muscles... which inhibits activity as someone mentioned.

Thanks for your help,
I have already replaced cow milk by soy milk, I will now replace my whey protein by some soy protein
I will also have a look to "pedialyte "

But already replacing fructose by simple sugar and cow milk by soy milk seems to improve the situation

I "use to" have the same problem. I swithced to HEED and limit my on bike calories to around 300/hr on long rides and have stopped the problem. I also use Perpetium on very long rides, no problem. Very short rides I only use H2O. It has also taken me a few years to get a feel for how much to drink on rides, too little it's bad, too much it's bad.

I have already heard that two much water can involve dehydratation, but I have never heard about diarrhoea...

At a certain hydration level you gut slows down or even stops absorbing water from the gut. With nowhere else to go the water continues on down the GI tract and gets expelled with everything else you body didn't want.

But I think I have found the problem: too much cow milk.
I used to drink cow milk, but with my recovery drink I drank too much in quantity and too often (I almost train 6 times a week), my guts did not support.
But I am still not sure, as I stopped cow milk 4 days ago, and only now I start to feel better (problably my guts took time to recover)

Anyway, thanks for your help all, I envoy again riding

Most commercial sports drinks are very poor for hydration. The problem is that to much plain water can lead to hyponatremia ( low sodium), however the actual salt content we would need for electrolyte replacement doesn't taste to good. So most companies add more sugars to make the drink more palatable this then changes the osmolarity of the drink and it's not absorbed properly more fluid is pulled into your gut to try and balance the osmolarity. Not only does this cause more dehydration but can lead to nausea and diarrhoea

Try cutting your sports drink in half with plain water

I had this problem a couple of times and it was immediately after downing a can of pop with ice cubes. Baaaaadddd...

Oh right...40 mile ride shouldn't do that to you...afaik. On the incidents I'm talking about...the distances were over 140 miles.

Try cutting back the mileage for a bit and see if it makes a difference.

As a fellow lactose-intolerant rider, I feel for you. Removing most dairy products from my diet helped me considerably with weight loss, and made me feel better as well.
