Abdominal Pain


Stomach ache or abdominal pain is a common complaint. Abdominal pain by itself is not a disease but is a symptom of a variety of underlying disorders. May have symptoms of heartburn, gas, bloating and burping.

Causes of Abdominal Pain

  • Psychogenic causes
    The abdominal pain occurs in non-diseased organs. Pain is believed to arise from stress, anxiety and depression. The real mechanism by which this process happens is not known.
  • Functional causes
    In this type, the affected organs are not diseased but there is an abnormal or changed functioning as a result of certain interactions between the body and the environment. Examples include:

    • Lactose intolerance
    • Dysmenorrhoea
    • Constipation
    • Diarrhea
  • Organic causes
    This type of abdominal pain is secondary to an underlying disease in the body. Examples include :

    • Inflammatory bowel disease
    • Peptic ulcer disease – up to 50% is related to Helicobacter pylori disease
    • Worm infestation
    • Pelvic inflammatory disease
    • Ovarian cyst
    • Urinary tract infection
  • Direct Injury – accident to the abdomen


Most of the time pain improves with home treatment. If you have abdominal pain without other symptoms, try the following :

  • Rest until you are feeling better
  • Drink plenty of fluids to prevent loss of fluid (frequent sips of beverage is easier on your stomach)
  • Avoid carbonated or caffeinated drinks such as soda pop, tea or coffee
  • Try eating small but frequent meals
  • Avoid spicy foods, fruits, alcohol
  • Avoid foods that are high in fat
  • Avoid aspirin and nonsteroidal anti-imflamatory medications

Other treatment would depend on the underlying cause.

  • Goals of treatment
    Return to normal function and relief of symptoms

    • Try simple pain killer such as paracetamol for dysmenorrhea (period pain).
  • When to see a doctor?
    • Pain following injury or accident
    • Your pain does not improve in 24 to 48 hours
    • Pain becomes more severe or frequent
