It depends on your underlying reason for having IIH. I find relief by cutting out caffeine and strength training. I think working on muscle strength not only helps stabilize your blood sugar levels, but it also helps in hormone regulation. Some people find that weightloss helps. I lost 100 pounds and got worse. Also, apparently certain strains of marijuana decrease pressure.

There are also 2 surgeries that can be done, but usually in cases where nothing else helps. The more common one is the LP Shunt, which basically involves a tube from the cavity around the brain into your stomach/bladder/abdominal cavity. It’s a pretty invasive surgery. More recently, there’s research on the VP Stent, which involves a device that helps open up a specific blood vessel that has been known to help reduce pressure in some cases. That one is more minimally invasive, but also less common
