I think that 9-10 BMs per day would technically be considered diarrhea if we're not talking little pellets. Where do they fall on the Bristol Stool Scale
? If he is having that many BMs and they are in the 5-7 range, it would be considered diarrhea even if the stools aren't completely liquid.
I used to think that it wasn't really a problem BM unless it was actually watery. But after dealing with my DD's GI issues I've learned to look at (and chart) texture, content (i.e. chunks of undigested food, mucous, traces of blood, etc.), smell and frequency as well as just whether it was liquidy or not.
The standard definition of diarrhea
is based on both texture and frequency:
|Diarrhea is defined as stool weight in excess of 200 grams per day. However, this definition is of little clinical value, since collecting and weighing stools is neither practical nor required except in a clinical research setting. A good working definition is three or more loose or watery stools per day or a definite decrease in consistency and increase in frequency based upon an individual baseline.
(200 grams is for an adult, I assume. I'm sure it would be less for a baby.)
I was reading a while ago that studies show many cases of "toddler's diarrhea" (chronic diarrhea in toddlers with no other symptoms) are caused by too much fruit and fruit juice.
Something you may want to look into is a sugar intolerance--lactose intolerance or fructose malabsorption (a.k.a. dietary fructose intolerance, not to be confused with hereditary fructose intolerance) would be the most likely possibilities, but there are other types of sugar intolerances or malabsorption as well. Of course there are other issues such as gluten intolerance that could be possibilities, but my guess would be it's just a matter of either lactose intolerance or too much fruit.
Apples and pears are the worst for fructose malabsorption, but other foods (even some vegetables and grains) can also be a problem, depending on the level of intolerance. Sometimes we crave the foods we don't tolerate well, and it sounds like he eats a LOT of apples. So that might be something to keep an eye on.
My DD's GI specialist said that anything that contains sugar can cause more frequent and softer BMs because sugar draws water into the intestines.
Baby E does much better if we give her more proteins, avoid too much sugar of any kind, and keep the amounts of fruit very small unless they are barely-ripe bananas or citrus fruits. We're pretty sure she has a sugar intolerance of some sort. 6 grams of sugar is enough to give her a bellyache and sweet-smelling softer stools, and her reducing substances stool test was positive (she had sugar in her stools). 2-3 blackberries will give her a stage 6 BM that smells like blackberries within 30 minutes, and larger amounts of more sugary fruits can give her severe watery diarrhea.
Does your DS like eggs? Adding eggs or meat to more of his meals and cutting back on the fruit and/or dairy products might help.
