Nipple Discharge: Causes & When to See a Doctor

Nipple Discharge: Causes & When to See a Doctor

Worried about nipple discharge? This guide covers causes in men, women, and children, different types (milky, bloody, clear, green), and when seeing a doctor is essential.


Have you noticed any discharge from your nipples and gotten a little worried? What might be causing it, who typically experiences it, and is it something serious? We’re diving into this topic, and we’ll explore it further in this article.

Causes of Nipple Discharge

Nipple discharge isn’t just a female thing; men can experience it too. When you’re trying to figure out what’s up, consulting a doctor is key, because, um, there’s a wide range of potential reasons for nipple discharge in both men and women, as we’ll see.

Causes of Nipple Discharge in Men

As we mentioned, guys can deal with nipple discharge too. Common, yet sometimes serious, culprits include:

  • Hormone imbalances, specifically, low testosterone.
  • Gynecomastia (enlargement of male breast tissue).
  • An infection in the pituitary gland, which can lead to breast milk production from the nipples.
  • Breast injury.

While nipple discharge is less common in men than in women, it’s still important to get it checked out by a doctor to rule out any serious underlying causes.

Causes of Nipple Discharge in Women

There’s quite a few reasons why women might experience nipple discharge. Often, it’s related to things happening in their lives, like when they’re no longer breastfeeding, which can sometimes last up to three years after stopping.

Other causes of nipple discharge in women include:

  • Breast infection.
  • Overstimulation of the breasts.
  • Breast pump usage.
  • Fibrocystic breasts.
  • Breast injuries.
  • Dilated milk ducts, also known as mammary duct ectasia.
  • Breast cancer.
  • Prolactinoma (a pituitary gland tumor).
  • Side effect from fertility treatments or certain medications like antidepressants.

It’s also vital to consider what medications you’re taking. Some can actually cause nipple discharge as a side effect. Some culprits are:

  • High blood pressure medication.
  • Antidepressants.
  • Anti-nausea drugs.
  • Sedatives.

Causes of Nipple Discharge in Children

In some cases, newborn babies, both boys and girls, might experience nipple discharge shortly after birth. This happens because the hormones from the mother are still circulating in the baby’s bloodstream.

No need to panic, though, as this discharge usually clears up within a few days.

Now, let’s pivot briefly. Something we haven’t covered yet, but is equally relevant, is the connection between stress and nipple discharge. High levels of stress can disrupt hormone balance and may lead to galactorrhea (milky nipple discharge). Managing stress through exercise, meditation, or other relaxation techniques could potentially help regulate hormones and reduce the likelihood of experiencing nipple discharge, particularly for those without other identified causes. Just a thought!

Types of Nipple Discharge

To pinpoint the underlying cause of nipple discharge, doctors often ask questions about the nature of the discharge, including its color and consistency.

Common types of nipple discharge include:

1. Milky Discharge

This is the most common type, and it’s often related to women who’ve recently stopped breastfeeding, or due to hormonal fluctuations before a period.

2. Bloody Discharge

It’s usually caused by non-cancerous growths like intraductal papillomas which are benign tumors inside the milk ducts. However, it could also be a sign of breast cancer.

3. Clear Discharge

This type of nipple discharge typically comes from just one breast, and it could be a sign of breast cancer, but not always.

4. Green Discharge

This type of nipple discharge is often associated with a breast abscess.

Nipple Discharge Treatment

Treating nipple discharge primarily involves addressing the underlying issue. Figuring out the root cause is essential. For both men and women, seeing a doctor is crucial to get to the bottom of things.

It’s also important to see a doctor if the nipple discharge continues after your period ends, or if you’re past menopause and are experiencing discharge from one nipple.

Key takeaways

  • Nipple discharge can occur in both men and women, and has a variety of causes.
  • The type and color of the discharge can provide clues about the underlying cause.
  • It is important to seek medical attention if you experience nipple discharge, especially if it is bloody, persistent, or accompanied by other symptoms.

FAQ, Myth & Facts

Is nipple discharge always a sign of breast cancer?

No, it isn’t. While nipple discharge can sometimes indicate breast cancer, it’s often caused by other, less serious conditions like hormonal changes, infections, or benign growths.

Can certain medications cause nipple discharge?

Yes, some medications, such as antidepressants, high blood pressure medications, and sedatives, can cause nipple discharge as a side effect. It’s important to review your medications with your doctor if you’re concerned about this.

Is it normal for women to experience nipple discharge after breastfeeding?

Yes, it’s fairly normal. Women can experience nipple discharge for up to three years after stopping breastfeeding due to lingering hormonal changes. However, if the discharge is bloody or accompanied by other symptoms, it’s best to consult a doctor.

Should men be concerned if they experience nipple discharge?

Yes, men should seek medical attention if they experience nipple discharge. While it’s less common in men, it can be a sign of hormone imbalances, gynecomastia, or other underlying health issues that need to be evaluated.

Does stimulating the nipples cause discharge?

Yes, sometimes it does. Overstimulation of the breasts, including during sexual activity, can lead to discharge.
