In simple words

Acid reflux happens when stomach acid travels up into the food pipe, causing heartburn, a sour taste, or food and fluid coming back up. Repeated troublesome reflux may be called GORD or GERD.

Clinical Meaning

Symptoms often worsen after eating, when bending, or lying down. Persistent symptoms need review because other conditions can look similar and treatment may be needed.

Common Causes

  • Reflux or a hiatus hernia
  • Pregnancy, increased abdominal pressure, or being overweight
  • Personal food and drink triggers, smoking, or alcohol
  • Some medicines or a delayed stomach emptying pattern

Clinical Red Flags

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

  • Call emergency services for new or severe chest pressure or pain with breathlessness, sweating, faintness, or pain spreading to the arm, jaw, shoulder, or back.
  • Arrange prompt advice for food sticking, painful swallowing, frequent vomiting, vomiting blood, black stools, or unexplained weight loss.
  • Book a review if heartburn happens most days or pharmacy treatment and lifestyle changes are not helping.

Lifestyle & Diet Support

Avoid lying down for two to three hours after eating, identify personal triggers rather than using a universal ban list, stop smoking, and consider weight support if relevant. A pharmacist can advise on antacids or alginates; do not use them regularly for long periods without advice.
