Overview

Indigestion is a term used to describe a feeling of fullness or discomfort during or after a meal. It can be accompanied by burning or pain in the upper stomach. It is a condition that is frequently caused by eating too fast, especially by eating high-fat foods quickly. There are many possible causes of indigestion, of which some are related to lifestyle.

Historical Perspective

Indigestion is an old english word meaning lack of digestion. Dyspepsia like symptoms have been recognized since the birth of medicine, however, the underlying pathogenesis of dyspepsia only began to be appreciated when Baillie in 1799 first described the anatomy and symptoms of gastric ulcer disease. The development of barium x-ray radiology, by Cannon in 1897, led to the clinical recognition of peptic ulcer disease and its relationship with its symptoms. Walter Alvarez at the Mayo Clinic in Rochester, MN was the first to apply the term functional dyspepsia in 1916 to describe patients with ulcer-like symptoms and a normal X-ray.

Diagnosis

History and Symptoms

Discomfort or pain in the upper abdomen, early fullness while eating, bloating, sense of fullness after eating are the usual symptoms expressed by the patients. Sometimes indigestion is accompanied by heartburn which is a separate condition.

Laboratory Findings

People without risk factors for serious causes of dyspepsia usually do not need investigation beyond an office based clinical examination.

Other Diagnostic Studies

People over the age 55 years and those with alarm features are usually investigated by esophagogastroduodenoscopy (EGD). People under the age of 55 years with no alarm features do not need EGD but are considered for investigation for peptic ulcer disease caused by Helicobacter pylori infection.

Treatment

Prevention

Avoiding foods and situations that seem to cause it may help. Indigestion can be a sign of a more serious problem. Seeing a health care provider if it lasts for more than two weeks and involves severe pain or other symptoms is very important.

Pathophysiology

Overview of Physiology

  • In humans, digestion begins in the mouth where food is chewed. Salivary amylase aids in the chemical breakdown of polysaccharides such as starch into disaccharides such as maltose.
  • The chewed food is pushed down the esophagus to the stomach through peristaltic contraction of these muscles.
  • Food enters the stomach where it is further broken apart and thoroughly mixed with gastric acid, pepsin and other digestive enzymes to break down proteins.
  • After consumption of food, digestive tonic and peristaltic contractions begin, which helps break down the food and move it through. Gastric emptying is the release of food from the stomach into the duodenum. Gastric emptying has attracted medical interest as rapid gastric emptying is related to obesity and delayed gastric emptying syndrome is associated with diabetes mellitus, aging, and gastroesophageal reflux.
  • After being processed in the stomach, food is passed to the small intestine. The majority of digestion and absorption occurs here after the milky chyme enters the duodenum. Here it is further mixed with three different liquids:
