Recurring stomach issues for two years

I'm a fit 60 year old male who eats right and exercises daily but is cursed with a recurring stomach ache that haunts me at least once a week. My churning noisy gut wakes me at daybreak and hangs around for around twelve hours. I had an endoscopy/colonoscopy two years ago and they found nothing., also a negative H. Pylori Test I've tried so many over the counter products and none seem to work. Any suggestions would be greatly appreciated. thanks Chris

Try drinking less sugar for a few weeks. It could be an acid issue within the stomach, and digestive system problems. Make sure to speak to your GP about it.
