The presence of white discharge when you squeeze your nipples, a condition known as galactorrhea, is often due to elevated levels of prolactin, a hormone primarily responsible for milk production.
Understanding Galactorrhea
Galactorrhea refers to nipple discharge that is not related to pregnancy or breastfeeding. While it can occur in women, it can also affect men and even newborns. The discharge can vary in consistency and color, but is often milky white.
Causes of White Nipple Discharge
Several factors can contribute to galactorrhea and the resulting white nipple discharge:
- Hormonal Imbalance: The most common cause is an overproduction of prolactin.
- Pituitary Gland Issues: The pituitary gland, located in the brain, produces prolactin. Tumors (usually benign), or other disorders affecting this gland can lead to excess prolactin production.
- Hypothyroidism: An underactive thyroid can also indirectly increase prolactin levels.
- Medications: Certain medications can stimulate prolactin release.
- Antidepressants: Some antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), are associated with galactorrhea.
- Antipsychotics: These medications can also increase prolactin levels.
- Blood Pressure Medications: Certain blood pressure medications may be a contributing factor.
- Nipple Stimulation: Excessive or frequent nipple stimulation can sometimes trigger prolactin release and discharge.
- Other Medical Conditions:
- Chronic Kidney Disease: Can disrupt hormone balance.
- Liver Disease: Similar to kidney disease, liver issues can impact hormone regulation.
What To Do
It's crucial to consult with a doctor to determine the underlying cause of the discharge. They will likely:
- Take a detailed medical history: This includes information about medications, other symptoms, and past medical conditions.
- Perform a physical exam: Including a breast exam.
- Order blood tests: To check prolactin levels and thyroid function.
- Consider imaging studies: Such as an MRI of the brain, to evaluate the pituitary gland if high prolactin is detected.
Treatment
Treatment will depend on the identified cause. Options may include:
- Medication Adjustment: If a medication is the culprit, your doctor might adjust the dosage or switch you to an alternative medication.
- Medication to Reduce Prolactin: If a pituitary tumor is the cause, medication can often effectively shrink the tumor and lower prolactin levels.
- Surgery: In rare cases, surgery may be necessary to remove a pituitary tumor.
- Treating Underlying Conditions: Addressing conditions like hypothyroidism can resolve galactorrhea.
In conclusion, white nipple discharge when squeezing your nipples (galactorrhea) can have various causes, most commonly related to hormonal imbalances, medication side effects, or excessive nipple stimulation. Consulting a healthcare professional for proper diagnosis and treatment is essential.
