It is caused by a decrease in intestinal tract motility leading to dry, potentially painful fecal evacuation. It may results from stress, lack of exercise, or insufficient fiber in the diet.Indigestion: Indigestion also known as dyspepsia refers to condition of impaired digestion and uncomfortable sensations which affect the upper abdomen with burning or pain.

The symptoms of indigestion include a feeling of fullness during a meal and bothersome fullness after a meal, burning or pain in the upper abdomen etc. It could be caused by a condition in the digestive tract such as gastro esophageal reflux disease (GERD).
