What causes green poop in adults

The truth is that the color and texture of your baby’s poop can be an excellent indicator of the overall health. In most cases, green poop is considered normal and can result from eating green foods.

There are however some isolated cases when the green poop can be a sign of an underlying condition.

In toddlers, green poop may result from any of the following:

1. Dietary Causes

Just like in adults, your child’s diet can greatly affect the color and texture of the stool. Such foods may include, green vegetables or food dyed with green, blue or purple food coloring.

To be sure that the green poop is only the result of dietary causes, avoid these foods for about three days to see if the stool returns to normal.

2. Excess mucus and bile

Decrease colonic time or rapid transit, which is the time when bile travels faster than normal to reach the intestine is also a possible cause of green poop in both adults and toddlers.

With this condition, the bile does not have time to change from its regular green color to brown.

3. Supplement and medication

Your toddlers’ poop can also turn green as a result of taking some medication and iron supplements. Also, speeding up the bowel activity through the use of laxatives can change the stool to green.

Indomethacin, a non-steroidal anti-inflammatory medication is one of the medications that can cause your baby’s stool to turn green.

4. Food poisoning

Food poising is also a possible cause of green poop in toddlers. For a child, the digestive system is very sensitive to a variety of different foods. In children, E Coli, a bacterial infection is the most common cause of food poisoning.

Green bowel movements

Bowel movement often varies from person to person. The truth is, there is no one complete description of a normal bowel movement.

Lack of a daily bowel movement does not mean that your baby is constipated, just like having more than one bowel movement a day does not mean that your baby has diarrhea.

For a toddler, a bowel movement should be soft and easy to pass. In most cases, the stool should be brown or golden brown. Thee poop should have a texture similar to peanut butter and size and shape close to a sausage.

In children with diarrhea, the gastrointestinal passage time is very rapid, in such cases, the stools will often come out the same color as the fluid of food that they consumed.

In most of the cases, a green bowel movement or that which varies a bit from the above description is often not a cause for alarm, especially for isolated cases.

However, if your child’s poop suddenly changes and persist for more than three bowel movements, is important you have him or her checked by a professional healthcare practitioner.
