11 Endocrine Disorder Symptoms You Should Not Ignore

10. New or worsening headaches, blurred vision, or peripheral vision loss

Headaches and vision changes that appear together should prompt consideration of pituitary gland issues. The pituitary sits at the base of the brain near the optic nerves, so growing pituitary lesions or hormone imbalances originating there can cause headaches and subtle changes in side vision. You might notice bumping into things on one side, difficulty reading the same line of text, or blurred vision that slowly worsens. Because many headaches are benign, the key is progression or accompanying visual field changes. Your clinician may perform a simple visual field test and, if results are concerning, order MRI imaging and hormone testing. Early diagnosis allows for targeted treatment—medical or surgical—depending on the cause, and often prevents permanent vision loss. If new vision problems come with a sudden, severe headache, seek emergency care.
