Gastroparesis testing is very easy. It's called gastric empty study and consists of eating some contrast laced scrambled eggs (you cannot taste the contrast) and then lay down on the imaging table for 2-3 hours while they scan and track the contrast to see how long it takes to completely empty form your stomach. It's this time period that determines whether you have gastroparesis.

If you do, then treatment is mostly lifestyle changes. Start by eating small meals and walk after eating (so gravity helps empty the stomach). Also avoid raw fruits and veggies that are hard to digest...like oranges, broccoli, salads, etc (there are gastroparesis diets online). Also avoid nuts and eating after 5-6 pm to help with nighttime symptoms (so your stomach can empty before you lay down for the night). Raising the head of the bed or using a wedge pillow will also help at night.

If your symptoms are really bad, then grind your food in a blender (the flavor is still there and only the texture changes). This helps to speed up the disgestion process by breaking down the food before it gets there.

If your lifestyle changes don't help (it takes a little time to get things going again), then there are medications to help. Unfortunately, the US has NO authorized medications for GI motility. Domperidone is the best medication for this and is available ANYWHERE else in the world, but not the US. Your doctor can write an RX for you to order online.

Hope this helps.
