What are these unusual noises my stomach makes?

Hello doctor,

I am concerned about the unusual noises my stomach makes. Anytime I eat or drink anything even if it is small, my stomach keeps making loud gurgling and rumbling sounds. I only drink water or fruit smoothies and avoid drinking soda, dairy, or any juice. I eat a very healthy diet and stay away from processed foods. I incorporate chia seeds, flax seeds, and oats in my diet for better digestion. I eat small meals and my stomach still does not settle. I try to exercise and do not see any changes. I wake up bloated and it remains the same throughout the day. I am not constipated or experiencing any symptoms like nausea, diarrhea, or pain in my stomach. I consulted a doctor two months back, he told me I had indigestion and prescribed medicines but that did not work. I am worried if this could be something else as I have been having this issue for four months already. Please help.
