Unintentional Weight Loss
Even without diarrhea, weight loss and abdominal discomfort may indicate a problem with fat digestion and absorption, a condition known as fat malabsorption. A disorder of the small intestine, pancreas or liver could cause this.
With fat malabsorption, there will often be changes in stool color and consistency.
Do your stools show one or more of the following changes:
yellow or beige color
a foul smell
oily, floating consistency?
