Gastroparesis symptoms can include early satiety, nausea, vomiting, bloating, abdominal pain and involuntary weight loss. If you have constipation or diarrhea as well, there is a newly described clinical entity that is a limited manifestation of autoimmune dysautonomia called Autoimmune Gastrointestinal Dysmotility (AGID), the prevalence of which is not known yet.

For constipation in general, colorectal surgeon, Dr Michael Levitt, promotes the use of magnesium sulfate before resorting to surgery. He has developed an encapsulated magnesium sulfate product, COLOCAP Balance as his protocol for treating constipation and as a way to avoid the chemical taste.
His plan for relieving constipation is to take it in large dose, 15 tablets over 1/2 an hour, but only once or twice a week. His book, “The Other Women's Movement” explains his thoughts on the subject. Some centres here in Australia are also now using this as a colonoscopy prep.
The idea is to promote a strong urge that can clear the bowel completely in one go so that it can relax from being empty. This can then enable the bowel to shrink back in size and become more sensitive to the natural urge to move your bowels.

Personally, I just use plain Epsom Salts, between 6 and 10 grams daily depending on the previous day's response, something I've been doing for close on 20 years. You can mix it in to juice, cordial etc to mask the taste.
You can combine it, or some other form of magnesium, with cayenne pepper capsules, something which I find too powerful as it moves my bowels too much.

There are a couple of other products I've come across for constipation relief using magnesium and also incorporating an oxygenation process that is said to aid in the digestive process. They are Colosan and Homozon. Ageless Hydro-C is another thing that I have seen some positive press about.

A novel idea I came across recently was nicotine patches placed on the abdomen near the ileocecal valve which helps if the valve is not opening in response to the nicotonic acetylcholine signalling process.
