I am 93 years old and have been diagnosed with a large sliding hiatal hernia. I try to eat 4-5 small meals a day, but become so nauseous that I am luck to have toast and possibly an egg for breakfast and soup and crackers later. I get too full or too nauseous for more. The barium upper GI test caused many bouts of copious vomiting, followed be diarrhea. My doctor again said to eat small meals 4-5 times a day and to see him again in two months. Because of my age, he will not operate. I have no high blood pressure or cholesterol problems. I am not diabetic. However, I always have a bitter taste in my mouth, belch, and feel constriction at times I my chest at times. I also cannot find a comfortable position in my adjustable bed. My scoliosis and lumbar stenosis seem to put pressure on my mid section as well. Any suggestions?
