Barretts Esauphagus, Slight Hiatel Hernia, 3 Ulcers. Been On Omneprazal

Barretts Esauphagus, slight hiatel hernia, 3 ulcers. Been on omneprazal 40mg. Concerned about my bones, I am a small framed white female, 77 years old in good health. Would rather take something natural for this. What do you suggest and what is the long range outcome for my bones. I walk regular.
