Hello. My Name Is Mariana And I Am 16 Years

Hello. My name is Mariana and I am 16 years old and I wanted to know if bloating is normal? Is it caused by food intolerances or my metabolism issues? I am a healthy person . I consume a lot of fruits and veggies with no processed foods and I avoid added sugars and fizzy drinks. I don't consume a lot of dairy and gluten at all. I do eat fibrous veggies like lentils. I wanted to know how I can manage my bloating concerns.
