As far as I'm aware and I'm only going by my diagnosis and on going battle (let's face it, it can be a battle at times) there isn't a cure. There are certain adjustments you can make in your lifestyle to help make it a little more bearable, I've changed my diet and made BIG adjustments with my lifestyle, I gave up smoking, limited my alcohol and started going to the gym!.
The advances we're making in the medical field are always improving so I'd like to think - in my lifetime - that they will eventually find a cure for this disease.
