Green Poop Causes

What Causes Green Poop?

Here is a list of the most common green poop causes:

  • Eating lots of green leafy plants

Most plants contain chlorophyll (a green pigment) and by eating an excessive amount of greens you may get a green stool. In most cases it’s only temporary and nothing to be worried about.

Eating a lot of greens may be healthy but you need to have a balanced diet.

  • Consuming a lot of iron

Excess iron in your body caused by taking iron supplements or by eating a large quantity of food that is rich in iron such as liver, mussels, sardines, spinach and broccoli may cause green poop. It is normally only temporary and not harmful.

Speak to your dietician if you are concerned that your diet is not balanced and cut down on iron supplements if you continue to experience green stools.

  • Artificial food coloring

Many products contain color additives such as dyes or lake pigments. The artificial food colorants that are normally added to candy, popsicles, ice-cream, cake frosting, etc. may cause a discoloration in your stool.

Even if the actual food coloring is not green in color but say blue or purple it may still cause your feces to look green.

Artificial food coloring is not healthy and if you are consuming a lot of it on a regular basis you should seriously consider changing your diet.

  • Bile from diarrhea

Green poop is often the result of bile (green in color). When bile passes through your large intestine it turns brown in color but if it passes through your large intestine too quickly as is often the case if you have diarrhea or as a side effect of using laxatives it may remain green.

If you are suffering from diarrhea your green poop should be temporary but make sure you drink enough water to avoid dehydration. It’s recommended that you consult with your doctor as soon as possible if you have chronic diarrhea.

  • Bile from eating fatty foods

Bile also gets released after a fatty meal to help break down the fat particles. In this case excess bile may also be the cause of your green poop.

If you consume lots of fatty foods and experience green stools as a result of the excess bile produced in your body you should really see this as your body sending you an early warning sign that you urgently need to change your eating habits.


Green poop is normally only temporary and not harmful. However, if you are experiencing other symptoms in combination with your green poop such as chronic diarrhea, pain, vomiting, etc. then please consult your doctor as soon as possible.

In most cases green poop can be attributed to a poor diet. This may include eating lots of junk food, fatty food or not following a balanced dieting plan. By eating more balanced and healthy meals, drinking lots of water and doing regular exercise you should be able to prevent recurring green stools.

Most people with digestive disorders have a long history of eating food that are not beneficial to them and may even be toxic. In such cases, regular exercise and following a healthy eating plan are recommended as a positive step in the right direction.
