Energy balance

Higher BMI (specifically >40 kg/m2) is associated with a significantly increased risk of severe vision loss and more severe papilledema in IIH patients.

If you have IIH, maintaining a lower BMI is crucial to protect your vision. A BMI over 40 kg/m2 significantly increases your risk of severe vision loss. Prioritize weight management to mitigate this risk.

GoodSupportsHIGH confidence
Each 10-kg/m2 increase in BMI confers a 1.4 times increased risk of severe vision loss.
