Which factors are cited as possible contributors to IIH?

• A. Underweight and dehydration
• B. Overweight and birth control
• C. Age over 80 only
• D. High cholesterol without other risk factors

Answer: (B)

Idiopathic intracranial hypertension is most consistently linked to factors that raise intracranial pressure through hormonal and metabolic pathways. The strongest and most commonly cited contributor is overweight, especially in women of childbearing age, which is why obesity is a key risk factor. Hormonal influences from birth control pills have also been implicated in some cases, so use of estrogen-containing contraception is considered a possible contributor. In contrast, being underweight or dehydrated isn’t typically associated with IIH, age being over 80 is not a recognized driver, and high cholesterol by itself without other factors doesn’t fit the pattern seen with IIH.
