Persistent abdominal bloating may be caused by digestive issues such as irritable bowel syndrome, food intolerances, or slow digestion. Maintaining a high-fibre diet, staying well-hydrated, and avoiding foods that cause excess gas, such as sugary drinks and fast food, may help. Over-the-counter medications, such as antiflatulents (e.g., simethicone or dimethicone) or antacids (e.g., aluminium hydroxide and magnesium hydroxide), may relieve symptoms. If the bloating persists, consult a doctor for further evaluation and treatment.
