Causes

Esophageal stricture is typically caused by scar tissue that develops as a result of the following:
  • Ingestion of damaging substances, such as household cleaning agents
  • Treatment of esophageal varices—enlarged veins in the esophagus
  • Injuries caused by an endoscope—a thin, lighted tube used to see inside the body
  • Esophageal cancer
  • Tracheoesophageal malformations

Risk Factors

Factors that may increase your chance of esophageal stricture include:
  • Gastroesophageal reflux disease (GERD)
  • Prolonged use of a nasogastric tube—a tube that is inserted through the nose to the stomach
  • Eosinophilic esophagitis
  • Scleroderma
  • Barrett's esophagus
  • Certain medications, such as those used to treat osteoporosis, or some antibiotics

Symptoms

Esophageal stricture may cause:
  • Difficulty swallowing
  • Pain when swallowing
  • Unintentional weight loss
  • Regurgitation of food—when food flows back from the stomach into the esophagus or mouth
  • Large chunks of food to get stuck in the esophagus

A meta-analysis found that mothers participating in a prenatal exercise group were less likely to have a large newborn, less likely to need a cesarean section, and no more likely to have a low birthweight baby than those who did not exercise. The study supports proper prenatal care advice which advocates for mothers to exercise during pregnancy if allowed by the physician.
