Gastrointestinal Diseases: Symptoms, Treatment & Causes

Gastrointestinal diseases

Gastrointestinal diseases are conditions that affect the gastrointestinal (GI) tract. GI diseases can occur anywhere from your mouth to the anus and can be with or without symptoms.

Gastrointestinal problems can manifest in two ways: functional and/or structural. When affected with the functional diseases the GI tract will appear normal upon examination but it will not move properly. In case of structural diseases the bowel will appear abnormal when examined and the GI tract will have issues as well. At times structural abnormalities may need surgical removal.

Common functional manifestations of Gastrointestinal Diseases are-

  • Constipation
  • Feeling of wanting to pass stool and nothing coming out
  • Nausea
  • Gassiness
  • Bloating
  • Belching / reflux
  • Diarrhea
  • Jaundice

Common examples of structural Gastrointestinal diseases are –

  • Hernia
  • Strictures
  • Stenosis
  • Gallstones
  • Hemorrhoids
  • Diverticular disease
  • Colon polyps
  • Colon cancer 
  • Inflammatory bowel disease

Causes of Gastrointestinal diseases

Factors that may trigger  Gastrointestinal tract issues are
