Constipation: Difficult, delayed and infrequent defecation (elimination of solid, semisolid or liquid waste material from the digestive tract via the anus) caused by insufficient water in the feces is called constipation. 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. It can appear with heartburn, belching, bloating, or nausea.
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 gastroesophageal reflux disease (GERD).
