Introduction
Occasional nipple discharge may consist of sebum, coagulated substances, or galactorrhea. Sebaceous glands on the skin of the nipple secrete oil to protect the skin around the areola and nipple. This secretion can sometimes result in occasional discharge on the nipple. Additionally, physical exercise or drinking large amounts of water may increase bodily fluid production, potentially leading to increased nipple discharge.

Occasional nipple discharge may be sebum, debris, or true nipple discharge.

1. Sebum

The skin of the nipple contains sebaceous glands that secrete oil to protect the areola and surrounding skin. This natural secretion may occasionally result in visible discharge on the nipple.

2. Debris

After exercise or drinking large amounts of water, increased bodily fluid secretion may occur. As these fluids evaporate through body heat, small flaky residues may form. These could also be accumulations of shed skin cells from around the nipple area.

3. Nipple Discharge

In women, long-term use of oral contraceptives may lead to nipple discharge due to the hormonal effects of progestin in the medication. Additionally, conditions such as mastitis or mammary gland hyperplasia cannot be ruled out as potential causes.

When occasional nipple discharge occurs, it is important to maintain cleanliness in the area and regularly change undergarments.
