Bed Wetting and The BTD


My son in almost 12 years old and still wets the bed almost nightly. Would typing his blood and following the right diet for his blood help him?


To the degree that a diet specific to his metabolism can have as its effects the elimination of foods your son is allergic or intolerant to.. then yes, following tha appropriate blood group diet could be quite beneficial. Bed-wetting is often caused by food intolerance. (1) Depending on the child's blood group, omitting cow's milk, wheat, corn, carbonated beverages, chocolate, refined carbohydrates (including junk food), and products containing food coloring can make a profound difference.(2)

While this problem can be very frustrating, keep in mind it is very common. The problem occurs in approximately five to seven percent of all 10-year-old children. The problem occurs in two to four percent of children ages 12 to 14. This is a problem that also tends to affect twice as many boys and girls.

Other than a small bladder for his age, some research has shown that a child may have insufficient nighttime quantities of a hormone called antidiuretic hormone (ADH). Generally, ADH levels rise at night and reduce urine production during sleep. However, in some children there is inadequate nighttime ADH production, and so he or she produces more urine. One approach to treating bed-wetting involves increasing ADH. A high wheat diet has been shown to decrease ADH.(3)

Some evidence seems to implicate variations in the body's levels of nitric oxide during the course of the night, and in some people it may drop low enough to cause excessive relaxation of their vascular beds. Since nitric oxide is a least partialy influenced by supplementation with the amino acid arginine, perhaps a trial of L-arginine supplementation could be explored along with dietary changes. Arginine is also part of the ADH hormone arginine vasopressin (AVP), and extra supplenetation may help maintain high enough levels of ADH over night to prevent bed wetting.(4)

The Ask Dr. D'Adamo internet advice column ran from 1996 to 2009, at which time Dr. D'Adamo's teaching and programming responsibilities no longer allowed him to devote time and resources to directly answering visitor questions. However we've recently reorganized this treasure-trove of material and made it again available to his readership. He occasionally posts new entries. These are marked with a NEW tag.
