Stomach aches after running?


Recommended Posts

Do any of you runners ever get these? The stomach ache usually comes an hour or so AFTER I run, not during or immediately after. I usually eat at least 2 hours before I run so I never run on a full stomach. I read an article that fiber could be causing the stomach ache but I thought fiber was good for you? I'm confused.

 

Any advice?

I'm sure that it could be any of a high number of problems, but if I were you, the first thing I would do is try upping your post run water intake (be sure to combine your water intake with a little food to help replenish your glycogen stores). It's possible that you're dehydrating yourself during the run to the extent that digestion of your pre workout (even if it's hours before) meal becomes more difficult for your system.

 

That's really just a wild ass guess though.

Ohhh, I almost started a thread on this exact subject a couple of weeks ago. I've been on and off with the gym recently, but a few weeks back I ate a PB&J then went to the gym about 30 minutes later. I power walked/ ran for about 30 minutes, came back home and immediately scarfed down an Activia yogurt. My stomach started hurting within 10 minutes and lasted almost all night.

 

Did a google search and came up with an article that said dairy and fiber consumption could be the culprit. I did a double whammy on by body with the sandwich (100% whole wheat bread) and the yogurt (obviously dairy).

 

Usually before exercising I eat a tablespoon of peanut butter. Exercising almost always kills my appetite so that's often my last food for the day (I workout in the evening). It was unusual of me to eat the yogurt, but I've learned my lesson.

Yeah, I read the same thing that diary and fiber consumption can cause it. I used to work out late at night and STILL got stomach aches, but I was eating sandwiches (whole wheat) and pudding (dairy). I was also drinking milk.

 

I have since switched my workout to the late morning (around 11:00 am) because I work 1-9 pm now. I usually will eat a fiber one bar and a yogurt in the morning so that may be the reason for these stomach aches. What breakfast foods would be good to eat in the morning? I usually get up around 9 am and eat breakfast then go to the gym around 11 am. I did a search on the internet and it said toast, but I only eat 100% whole wheat so that would not work.

I agree with this. Our unit doc told us that dehydration is a very common cause of stomach aches

So it was definately the fiber/dairy that was causing the stomach ache. I experiemented today and ate some grapes and white toast for breakfast instead of my usual yogurt and fiber one bar. I did not have any stomach ache at all, HOWEVER I felt like I had less energy to run.

 

What are good foods to eat for breakfast that are NOT fiber and will give me energy?

About 20 minutes before exercising I usually eat a tablespoon of peanut butter. Seems to shoot me with energy.

 

Does that sustain you through your workout though? I run for like 45-50 minutes, I don't want to get hungry while I'm running, that is the worst! I eat breakfast around 9 am and then workout around 11 am.

 

I was sooooo glad not to have a stomach ache today, it was wonderful! They are so painful.

Generally it does, I can easily go 45 minutes on that, but keep in mind I work out very late at night. I have eaten dinner and snacked by the time I hit the gym.

I've never gotten a stomach ache after a run, but on occasion I do get nauseous.

 

I tend to snack on nuts and fruit immediately beforehand. I'm always worried I will get cramps but so far, so good.

 

I think protein is the best way to start one's day. I like having an omelet. It seems to fill me up with energy that stays level throughout the morning.

An omelet has dairy in it unfortunately. :( Too bad, because I really love them.

Maybe I'm a little hazy on my definition of "omelet", but where exactly does dairy come into the picture here?

Cheese is considered a dairy product...

Ah but of course we can make an omelet sans cheese?

 

I see where you're coming from now though.

So I got another stomach ache today!!! I can't figure out what is going on. I spoke with my coworker who used to be a marathon runner and she said it might be the muscles in my stomach that are hurting due to the strain I am putting on them..especially since I run on inclines on the treadmill. My stomach muscles have to work a lot harder then running on a level incline. It might be that, but I also have trouble going to the bathroom as well, so is it indegestion? I don't know. I'm thinking about seeing my PCP and seeing what he has to say about it. Maybe there is something wrong with me...

Combination or series of good techniques can help reduce and stop your stomach pains after a jog. First, check your nutrition and hydration before and after your run. Do not eat too much or the wrong things too early before your race. Be sure to avoid dairy products, rich in fiber and fat, heavy foods, preferably up to 24 hours before hand.

Stomach ache as in, you feeling like going to the toilet?

 

That's actually a very normal byproduct of exercise. Some people just habitually **** after their daily exercise, in fact. Exercise stimulates certain muscles, which in turn eases the movement of food down your gastrointestinal tract. That is why people with constipation are advised to, in addition to eating fibre-containing food and drinking lots of water, to exercise regularly.

 

I wouldn't cut down on the fibre if I were you. Dairy products, on the other hand, could be potential culprits, but ONLY if you're lactose-intolerant or have IBS.
