What are the causes and symptoms of acid reflux, and can it cause inflammation in the neck region?
Acid reflux happens when stomach acid flows back into the food pipe, usually because the valve between the stomach and esophagus becomes weak. Common causes include spicy/oily foods, overeating, lying down after meals, stress, obesity, smoking, caffeine, and certain medications. Symptoms often include burning in the chest (heartburn), sour taste in the mouth, bloating, throat irritation, cough, and difficulty swallowing. Yes, ongoing acid reflux can cause inflammation in the neck/throat region, leading to throat pain, a lump-like feeling, hoarseness, ear discomfort, and even neck muscle tension. If symptoms are frequent, lifestyle changes and proper medication can help, and a doctor may recommend tests if it persists.
