Constipation

Constipation is common in autism due to the lack of gastric motility.  H2 receptors stimulate the production of gastric acid and digestive enzymes, which in turn stimulate intestinal motility.  So if the MAO-A activity is deficient, the H2 receptors don’t get adequate stimulation.  Many children or adults with autism are taking magnesium supplements orally or in the form of Epsom Salts baths to counteract the constipation. 

 Many parents have reported that their child’s constipation is resolved within days of starting the Respen-A.  It is recommended to stop the increased magnesium supplements when starting Respen-A as these can result in loose stools or diarrhea.  Also the increased magnesium intake can interfere with the calcium absorption that is necessary when using Respen-A.
