Acidity, also known as acid reflux or gastroesophageal reflux, is characterized by stomach acids backing up into the esophagus, resulting in symptoms like heartburn and nausea. Dr. Aravind Badiger, Technical Director at BDR Pharmaceuticals, explains that skipping breakfast can significantly contribute to acidity. When individuals fast overnight for 8-10 hours, their stomach produces acids in anticipation of food. If breakfast is skipped, these acids can irritate the stomach lining, leading to discomfort. Common signs of acidity include a burning sensation in the chest, bloating, and a bitter taste in the mouth. To mitigate acidity, it is recommended to eat a balanced breakfast within an hour of waking, consume easily digestible foods like oats and fruits, and avoid caffeine in the morning. If symptoms persist, seeking medical advice is crucial, as chronic acidity can lead to more serious health issues.
