I have food allergies, Hypokalemic Periodic Paralysis, and SPD. If my food allergies or Hypokalemic Periodic Paralysis are out of control, so is my SPD. SPD can also make the other two much worse.

It took me a few years of hard work, but by getting each condition better under control I was able to improve the others.

For my food allergies, I had to do 100% avoidance and stop cheating so much because some of my food allergens taste real good. Trying to manage my Hypokalemic Periodic Paralysis actually helped with that, since a lot of my food allergies are in sweets and due to the Hypokalemic Periodic Paralysis I had to keep the number of carbohydrates in general real low (sweets have a lot of carbohydrates).

Once I got those two conditions mostly under control, my SPD stopped getting worse on a seemingly daily basis. With the exception of smell, my senses have not gotten worse in about a year and a half and have actually gotten much better. Prior to that, at least every 3 months I would see a big increase in my sensitivity levels.
