Green Diarrhea In Newborns: Is It Normal?

It is perfectly normal for a newborn to have green diarrhea. Meconium, a newborn's first stool, is greenish-black and varies in consistency. Over the next few days, the stool begins to take on an army green colour, then it turns mustard yellow (if breastfeeding) or tan-brown (if formula feeding). Green diarrhea can be caused by a number of factors, including diet, a food allergy or intolerance, or an infection such as a stomach bug. If you are concerned about your baby's health, it is always best to consult a doctor.

Green diarrhea in newborns is usually not a cause for concern

Causes of Green Diarrhea in Newborns

The most common cause of green diarrhea in newborns is the rapid movement of stool through the digestive tract, not allowing enough time for stomach bile to turn it brown. This is often the case with diarrhea, which travels more quickly through the intestines than regular stool.

Green diarrhea can also be caused by certain foods in the mother's diet if the newborn is breastfed, or in the newborn's diet if they have started solids. These include green, leafy vegetables like spinach, peas, and green beans, as well as foods containing green dye.

Other causes include iron supplements, which are sometimes found in formula or supplements, and phototherapy treatment for jaundice.

When to Be Concerned

While green diarrhea is usually harmless, it can sometimes indicate a viral or bacterial infection, a food allergy, or intolerance. If your newborn has green diarrhea and is also showing signs of illness, such as fever, vomiting, and/or diarrhea, it is important to call your healthcare provider to ensure they do not become dehydrated.

Additionally, certain stool colours may warrant a call to your doctor. These include white, red, or black stools, which can indicate an infection, gastrointestinal bleeding, or a problem with bile production.

Green diarrhea can be caused by a mild infection

Green diarrhea in newborns can be alarming for parents, but it is usually not a cause for concern. It is common for babies to have green stools when transitioning from meconium—the first black, tarry, and sticky bowel movements after birth—to regular baby stool. During this transition, the stool can be dark green for a day or two.

However, green diarrhea can also be caused by a mild infection. Diarrhea occurs when the small intestine cannot absorb enough water, often due to a virus. It can also be caused by bacterial infections, such as salmonella, or parasites, such as giardia. Diarrhea can lead to dehydration, so it is important to monitor your baby for signs of dehydration, such as a dry mouth, lips, and tongue, as well as a lack of tears when crying. If your baby has diarrhea that lasts for more than a day or shows any signs of dehydration, it is important to consult a doctor.

To prevent dehydration, ensure that your baby is drinking enough fluids. For babies younger than 6 months, this should be in the form of breast milk or formula. For older babies and toddlers, you can offer pediatric electrolyte drinks in addition to breast milk or formula. It is also important to avoid over-the-counter anti-diarrheal medicines, as these can be harmful to young children.

In most cases, green diarrhea in newborns is not a cause for concern and can be managed by monitoring your baby's fluid intake and keeping them hydrated. However, if the diarrhea persists or is accompanied by other symptoms, it is important to seek medical advice.

Green diarrhea can be caused by a food allergy or intolerance

Green is a common colour for baby poop, and it's usually not a cause for concern. However, if your baby is also ill, or if you're concerned that something is wrong, it's best to call the doctor.

Green baby poop can be caused by a number of things, including:

• Diet: Once your baby starts eating solids, anything that's green in their diet can turn their poop green, including pureed foods such as spinach, peas, green beans, and other leafy greens.
• Food allergy or intolerance: Your baby may have an allergy or intolerance to milk proteins, for example, in their formula or in breast milk if the lactating parent has eaten dairy. If your baby has a food intolerance, they may also develop eczema and act irritable after feeding.
• Infection: Your baby may have a viral or bacterial infection, like a cold or stomach flu, which can cause green diarrhea.
• Medication or supplements: Iron supplements and certain medications (taken by your baby or you, if you're breastfeeding) can turn a baby's poop dark green.
• Foremilk-hindmilk imbalance: Breast milk changes throughout a nursing session. The breasts first produce low-fat and high-sugar "foremilk", which gradually turns into high-fat, high-calorie "hindmilk". If your baby tends to have short nursing sessions or you have an oversupply of breast milk, they may be getting more foremilk than hindmilk, which can lead to gassiness and green, frothy stools.
• Phototherapy: If your baby is being treated with phototherapy for jaundice, it may turn their poop greenish.

When to see a doctor

While green baby poop is usually nothing to worry about, it's important to call the doctor if your baby has green diarrhea and is also showing signs of dehydration, such as:

• Peeing less often (fewer wet diapers) and the urine is dark
• Acting fussy or irritable
• No tears when they cry
• Unusual drowsiness or sluggishness
• Sunken soft spot on the top of the baby's head
• Skin that isn't as elastic as usual (doesn't spring back when you gently pinch and release it)

Dehydration is a risk of diarrhea and can be dangerous for newborns

Diarrhea is the body's way of getting rid of germs. It happens when the small intestine cannot absorb enough water, which is often due to a virus. It can also be caused by bacterial infections, medications, or parasites. While it is usually not a cause for concern, it can be dangerous for newborns.

The primary risk associated with diarrhea is dehydration, which can be life-threatening. Dehydration occurs when the body loses more fluid than it takes in, and it doesn't have enough water and other fluids to function normally. Newborns are especially vulnerable to dehydration because they have a higher surface area-to-volume ratio, so they lose a higher proportion of fluids from a high fever or burns. Additionally, young children often cannot communicate that they are thirsty or get a drink for themselves.

Signs of dehydration in newborns include:

• Absence of a wet diaper for three or more hours
• Crying with no tears
• Sunken eyes or cheeks
• Sunken soft spot on the top of the head
• Dry mouth, lips, and tongue

If you suspect your newborn is dehydrated, it is important to seek medical attention immediately. Mild dehydration can be treated at home with oral rehydration solutions like Pedialyte, but more severe cases may require treatment in the ER or hospital. To prevent dehydration, ensure that your newborn is taking in enough fluids, especially during hot weather or when they are ill.

While green diarrhea in babies is usually not a cause for concern, it can sometimes indicate an infection or allergy. If your newborn has green diarrhea, monitor them closely for any signs of dehydration and contact your doctor if you are concerned.

Green diarrhea can be caused by certain medications

Green diarrhea in newborns can be alarming but is usually not a cause for concern. A newborn's first bowel movements are black, tarry, and sticky stools known as meconium. After a few days, you should see a transition to green poop that is less tacky than meconium. This green poop is normal and is caused by the transition from meconium to regular baby stool.

Medications that can cause green diarrhea may include:

• Antibiotics
• Anti-parasitic drugs

It is important to monitor your baby for dehydration if they are experiencing diarrhea, as this can become a concern if it lasts for more than a day. Signs of dehydration include a dry mouth, lips, and tongue, as well as a lack of tears when crying. If your baby is less than 6 months old and has diarrhea, it is recommended to bring them to a pediatrician.
