The truth about why it’s so hard to poo on holiday revealed

So why do we get vacation constipation? And how can get rid of it?

It's usually because of the sudden change in eating routine, gastroenterologist Vijaya Rao explained.

Your body is used to the foods you regularly eat at home, so when that changes, your digestive system gets confused and reacts differently.

"A lot of times it's just the change in routine, coupled with the extra stress of travelling," Dr Rao, a professor of medicine at The University of Chicago School of Medicine, told 

The constipation can start when you're on your way - whether it's on the plane or a long road trip.

Toilet access is somewhat limited while travelling and this can disrupt your digestive system, Dr Vijaya explained

And chances are you also feel less comfortable pooping in a hotel toilet, so you hold on a little longer than normal.

Your sleep also plays a role in the digestive process.

Normally when we travel our sleep is disrupted a bit, meaning our bodies don't process food as well as they usually do.

have actually linked sleep disorders to digestion issues.

All of this, coupled with the different foods you are eating, can wreak havoc with your insides.

But, luckily, there are ways you can beat the bloat and get back to enjoying your holiday.

1. Protect your gut

Before your trip, take some probiotics (live bacteria and yeasts, usually added to yoghurt or available as supplements) to keep your guy happy and healthy.

Some research suggests probiotics can soften stools and ease constipation.

Dr Rao said more research is needed into how probiotics work, but it can't hurt to take them.

2. Keep it moving

Moving around can actually help your bowels, so get walking!

Even when you're on the plane you should try to get up and move as much as you can.

This will get your blood flowing to keep your digestive system working, the doctor said.

3. Eat right

Keeping your bowel healthy starts with what you are putting in it.

If you're indulging and eating lots of high-fat, unhealthy junk foods coupled with too much booze - hey no judgement, you're on holiday - then you're likely to have some toilet trouble.

That doesn't mean you can't enjoy a few on your holiday though, just make sure you are also drinking plenty of water and eating lots of high fibre foods like fruit and vegetables to get everything moving.

And if you are still struggling to poop, a laxative can help get your bowels moving again, the expert explained.
