Is watery discharge from one nipple normal?

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Here is a quick overview of what might be going on:

Watery nipple discharge from one side (left). Here are the possible causes (from most to least common):

1. Hormonal fluctuations: It can be related to stress, irregular cycles, thyroid imbalance, or elevated prolactin. Squeezing the nipple can also trigger discharge in sensitive cases.

2. Fibrocystic breast changes: A benign condition where breasts feel lumpy or tender, sometimes causing discharge.

3. Duct ectasia: Mild inflammation of the milk ducts may cause watery, clear, or even greenish discharge, more common with age but can happen earlier.

4. Medications or herbs: Some herbs (like fennel or fenugreek) or medications (especially antidepressants) can affect hormone levels.

5. Less likely, but worth ruling out: High prolactin levels (for example, prolactinoma (a non-cancerous tumor of the pituitary gland that causes high levels of prolactin)).

6. Thyroid dysfunction: Infection or a breast mass (especially if the discharge is bloody, foul-smelling, or occurs without squeezing).

Next steps:

1. Avoid squeezing as it can worsen or prolong the discharge.

2. Monitor for pain, lumps, fever, skin changes, or spontaneous discharge.

See a doctor if it continues for several days or happens on its own (without touch). They may recommend:

1. A clinical breast exam.
2. Blood tests (prolactin, thyroid function).
3. Breast ultrasound.

I hope this helps.

Kindly revert so I can assist you further.

Thank you.
