Gastrointestinal (GI) conditions may affect your digestive tract, as well as organs such as your liver, pancreas and gall bladder.

Upper gastrointestinal tract

The upper GI tract consists of the mouth, oesophagus, stomach and the first part of the small intestine. It digests your food and prepares it for processing in the lower GI tract. Common conditions affecting the upper GI tract include:

Gastritis

Vomiting

Heartburn

Indigestion

Peptic ulcers

Celiac disease

Barrett’s oesophagus

Acute abdominal pain

Bleeding in the upper GI tract

Gastroenteritis (food poisoning)

Gastro-oesophageal reflux diseases (GERD)

Stomach acid conditions

Helicobacter pylori

Stomach cancer

Lower gastrointestinal tract

The lower GI tract begins at the midsection of the small intestine and extends throughout the large intestine until the anus. It is involved in the digestion and absorption of food nutrients, as well as the processing of waste products for excretion. Conditions associated with the lower GI tract include:

Diarrhoea

Constipation

Colon polyps

Lactose intolerance

Diverticular disease

Haemorrhoids (piles)

Bloating or abdominal pain

Bleeding in the lower GI tract

Irritable bowel syndrome (IBS)

Inflammatory bowel diseases (e.g. Crohn's disease and ulcerative colitis)
