“Why do I feel bloated all the time?”

Many possibilities. If the condition is chronic then I suggest you consult a specialist.

Most bloating is caused by carbohydrate malabsorption. Chances are that you eat a lot of vegetables. These are notorious for causing bloating because they are not digested well, enter the small intestine and draw fluid into the lumen, resulting in bloating. I suggest that you first consider following a low FODMAP diet. It is a low carb diet with great success at reducing bloating.

If this doesn't help then get evaluated by a GI doctor. You might need testing for specific carbohydrates or look for other possible causes of bloating that are much less common (e.g. bacterial overgrowth).
