With age the digestive tract like other bodily systems slows down. The muscles become stiffer, weaker, and less efficient.
As a result some of the digestive tract problems that can occur are: heartburn, peptic ulcers, diarrhea, constipation, gas, stomach pain, and inflammation in the colon.
Fortunately, there are ways to decrease these discomforts by, staying hydrated, limiting fats, consuming fiber, and exercising on a regular basis.
