In simple words

Indigestion is discomfort in the upper tummy or chest that can include fullness, burning, bloating, nausea, or burping after eating.

Clinical Meaning

It is common and may be linked to reflux, certain foods or drinks, medicines, or stomach irritation. Persistent symptoms should be assessed rather than self-diagnosed.

Common Causes

  • Gastroesophageal reflux disease (GERD)
  • Gastritis or peptic ulcer disease
  • Irritable Bowel Syndrome (IBS)
  • Dietary intolerance or food allergies

Clinical Red Flags

Seek urgent medical attention at an emergency department or primary care clinic if you present with any of the following symptoms:

  • Unexplained weight loss or persistent vomiting
  • Difficulty swallowing (dysphagia) or gastrointestinal bleeding (melena)
  • Severe overnight abdominal pain waking the patient

Lifestyle & Diet Support

Try smaller meals, avoid lying down soon after eating, and notice whether particular foods, drinks, or medicines trigger symptoms. A pharmacist can advise on suitable short-term treatments.
