The feeling of always being bloated can be caused by several common factors, including:

• Gas buildup in the stomach and intestines, often due to swallowing air, eating foods like beans, cabbage, carbonated drinks, or having indigestion.
• Fluid retention caused by salty foods, hormone changes (like before periods), or medical conditions such as liver or kidney issues.
• Food intolerances, especially lactose and gluten intolerance, which cause the digestive system to react adversely to certain foods.
• Chronic conditions such as irritable bowel syndrome (IBS) or inflammatory bowel diseases, which can cause bloating alongside other symptoms like diarrhea or constipation.
• Eating habits like eating too fast or chewing gum, which increase swallowed air.
• Other medical causes such as infections, hormonal fluctuations, constipation, and disorders affecting gut motility or bacterial balance.

If bloating is persistent and accompanied by pain, weight loss, or other serious symptoms, it may require medical evaluation to rule out conditions like celiac disease, pancreatic insufficiency, or more serious digestive diseases. In summary, persistent bloating often stems from diet, food intolerances, swallowed air, digestive disorders like IBS, or fluid retention, and may also be influenced by stress or hormonal changes.
