About the symptom

Lactation is the secretion and yielding of milk through the mammary glands, which are located in the breasts.

When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Breast milk outside pregnancy or as a man

Possible causes

  • Hypopituitarism

    The pituitary gland is a part of the brain that controls hormone levels in the entire body. In hypopituitarism, this control is disrupted, causing hormone levels to drop and organ function to decrease. Causes include tumors, previous radiotherapy, infections and autoimmunity (body's immune system attacking itself).

  • Hyperprolactinemia

    Excessively high prolactin (hormone that releases milk) levels in the blood. Causes include medications and brain tumors.

  • Acromegaly

    A condition caused by abnormally high levels of growth hormone in the blood. It is usually caused by benign (non-cancerous) tumors in the brain.

  • Pituitary adenoma
  • Mastopathy
