Ulcer Danger Signs: When Stomach Pain Is an Emergency

HealAlright Editorial Team · · 2 min read

Most stomach ulcers are uncomfortable rather than dangerous, and they heal with treatment. But a small number cause serious complications that need emergency care. Knowing the signs can save a life.

Signs of a bleeding ulcer

  • Vomiting blood, which may be bright red or look like coffee grounds
  • Black, sticky, tar-like stools, or stools with dark red blood
  • Feeling faint, dizzy or light-headed, especially when standing
  • Unusual paleness, sweating or a racing heartbeat
  • Sudden tiredness or breathlessness, which can signal significant blood loss

Signs of a perforated ulcer

A perforation is a hole through the wall of the stomach or duodenum. Signs include:

  • Sudden, severe, sharp pain in the abdomen that spreads and keeps getting worse
  • A hard, rigid abdomen
  • Fever, vomiting and feeling very unwell

Signs of a blockage

Swelling or scarring near the outlet of the stomach can block food from passing. Signs include:

  • Repeated vomiting, sometimes of food eaten hours earlier
  • Feeling full after a few bites
  • Unintended weight loss

What to do

  1. Seek emergency care immediately. Go to the nearest emergency department or call your local emergency number.
  2. Do not drive yourself if you feel faint.
  3. Do not eat or drink until you have been assessed, in case you need a procedure.
  4. Take a list of your medicines, especially painkillers, aspirin and blood thinners.

Who should be extra careful

  • People over 60
  • Those taking aspirin, NSAIDs, blood thinners or steroids
  • Anyone with a previous ulcer or bleed

Other symptoms that need a prompt doctor's visit

Not emergencies, but they should be checked soon: unexplained weight loss, difficulty swallowing, persistent vomiting, anaemia, or new indigestion that starts later in life.

Key takeaway

Most stomach pain is not an emergency. But blood in vomit, black stools, fainting or sudden severe pain always are. Act fast, then treat the underlying cause so it does not happen again.
