Urinary accidents and foul smell to the urine can be the first signs of a urinary tract infection. Uti's can go on undiagnosed for months before they work their way up into the kidney..if they do it is at this point a fever will start, they sleep excessively,won't eat, and basically become pretty ill. So don't rule out a UTI if there is no fever.
If a uti is ruled out, another thing that can cause bedtime incontinence is an imbalance in the calcium to magnesium ratio. Milk has 8 times the CA compared to MG. Children with high dairy and milk diets can have increased incontinance issues. Also some breads have calcium propionate which affects bedwetting. Calcium is now added to many foods. Watch the labels. Calcium is a necessary and good thing, but too much calcium causes hypocalcification and depletes Magnesium. Supplementing magnesium and decreasing breads and dairy, increasing hormone free meat and organic veggies, helped for our son. Everytime he drinks milk at night - he pees the bed.
The pituitary gland is part of the endocrine system, and it is responsible for secreting ADH (antidiuretic hormone), which regulates water reabsorption. Low ADH is connected to bedwetting. Diabetes can be a cause for bedwetting. Deficiency of ADH causes diabetes and excessive loss of water, which is an edocrine disorder.
There are endocrine disrupting chemicals in our environment. They bind to steroid receptors and mimic normal hormones. Mercury is included, and so is SOY. 70% of processed/produced foods have some form of soy. Percholate in milk, bromine in breads and baked goods, chlorine in tap water are endocrine disruptors. I am not saying they are to blame because I don't know, but they are something to consider.
All communications in the body are regulated either by the endocrine system or the nervous system. Many hormone chemicals are extensions of the nervous system.
The B complex vitamins are nervous system supporters and again so is MG. I give my kids liquid b complex drops under the tounge.
There are herbal and prescription sublingual sprays available. I have never used them and personally I would try to improve the diet and get out as much chemical additives, food colorings, etc, before I went the other route.
Some presecription incontinence meds have Imaprine in them, which is a tricyclic antidepressant.
Please use this as a springboard for your own research and consult your doctor.
