Hi. Thanks for your query. Noted the history of pains for the last 6 months, mostly the joints and arms and legs, like sciatica and so on. Presently have pains in the stomach and diagnosed as diverticulitis and gastritis and wants to go natural way. This is a great idea to have natural cure but is not possible in all the diseases or disorders. In Gastritis you can have natural remedy by the following: Soft bland diet. 4 equal meals with proper spacing. No stress or anxiety Early to bed and early to rise. Regular exercises. These will act nicely to recover you from gastritis , the treatment to be supplemented by PPI to start with. About Diverticulitis; Natural fibers and regularity as above helps here too. There are many cases wherein there is diverticuli but no inflammation and are found as incidental finding. But whenever required you need to have clinical evaluation and proper diagnosis and treatment.
