What causes acid reflux, what are its symptoms, and can it cause neck inflammation?
Acid reflux occurs when stomach acid flows back into the oesophagus (food pipe) due to a weakened lower oesophageal sphincter. It is often triggered by overeating, obesity, certain foods (such as spicy, fatty, or acidic items), smoking, or lying down shortly after eating. Common symptoms include heartburn, regurgitation, chest discomfort, throat irritation, and difficulty swallowing. In some cases, refluxed acid can irritate the larynx (voice box) or surrounding tissues, potentially causing neck inflammation.
