Why Your Vegan Poop Might Be Green…And What To Do About It

It might feel a bit weird, but looking at your poop occasionally is a good habit.

It can help you gauge how well your body is working.

Something that happens to a lot of vegans is that they look down one day and see green poop (stool).

The good news is that it’s generally not something to be worried about, and is usually just a one or two time occurance.

If it happens a lot, you should go see a doctor.

So why does it happen?

There are generally 2 causes.

Reason #1 – You’ve Been Eating a Lot of Vegetables With Green Pigment

The Mayo Clinic actually has an entry for green stool, where they explain the the most common cause is something you ate.

Something with a lot of green pigment, like spinach or kale, for example.

In small amounts, they won’t turn your poop green, but if you’ve recently had an exceptionally large amount, that’s likely the cause.

It’s not like it’s bad for you, but you probably want to dial back on the leafy greens a bit.

Reason #2 – You’re Not Absorbing Nutrients From Food

This may be cause for concern.

Malabsorption is a digestive disorder that could be indicative of a serious problem, and can cause green stool.

When food passes through your digestive system too quickly, your bile doesn’t break down as it should, which passes the green color on to your stool.

If this is the case, there’s a good chance that you also suffered from diarrhea.

Is this a serious concern?

That’s the tricky part. Several things can cause this, and some are serious, while others aren’t.

If you just ate some contaminated or expired food, you’re likely fine, and this won’t be a reoccurring issue.

However, if you have malabsorption from any other cause, it could cause you to become deficient in other nutrients (vitamins, minerals, essential fats) and cause serious harm.

Regardless, it’s a good idea to be on the safe side and see a doctor if you feel sick.

A doctor can do stool and blood tests to test for deficiencies.

Conclusion

Overall, vegans are at more risk of harmless green poop because we tend to eat a lot of green vegetables.

However, if you feel any sickness, or the green poop carries on for multiple days, it’s a good idea to see a doctor.
