Gastrointestinal (GI) Disorders
Gastrointestinal (GI) disorders affect millions of people worldwide and can range from mild, temporary discomfort to serious chronic illnesses. These disorders impact the digestive tract, which includes the oesophagus, stomach, small intestine, large intestine (colon), rectum, and anus. Understanding the common signs, symptoms, causes, prevention, and treatments can help you take control of your digestive health.
What Are Gastrointestinal Disorders?
Gastrointestinal (GI) disorders are conditions that affect the normal functioning of the digestive tract. They are broadly classified into two categories:
- Functional GI Disorders: The GI tract appears structurally normal but doesn’t function efficiently. Example: Irritable Bowel Syndrome (IBS).
- Structural GI Disorders: Involve visible physical damage, such as ulcers, tumors, or inflammation (e.g., Crohn’s disease, ulcerative colitis).
Common Causes of Gastrointestinal Disorders
- Unhealthy Diet: Low in fibre and high in fats or processed foods.
- Infections: Pathogens like H. pylori or noroviruses.
- Stress and Anxiety: Impacts gut motility and sensitivity.
- Poor Lifestyle Habits: Sedentary behavior, smoking, and alcohol.
- Medications: Long-term NSAIDs or antibiotics.
- Genetic Factors: Hereditary conditions like celiac or Crohn’s.
- Autoimmune Conditions: Immune attacks on digestive tissues.
