I'm 67. Extremely Fit And Eat A Healthy Diet. For

I'm 67. Extremely fit and eat a healthy diet. For 2 weeks I have had mid abdominal discomfort, mild bloating, no change in appetite, normal stools but increased gas and burping. Today I am drinking a lot of aloe juice, 6 x8 oz glasses and have skipped lunch. I'm thinking I should see a gastroenterologist in the next few days. I have no history of GI problems. Do you agree?
