Had upper Endo, found lots 3-6mm Gastric Fundic Polyps, were benign, do they need to be monitored? Doc said no, grandpa died stomach cancer, concerned

If these polyps: were benign, they are not precancerous. Stomach cancer do not necessarily run in families. If you have no other risk factors, such as H. pylori infection, alcohol, or tobacco, your risk is probably baseline. Ask your gi specialist for specific recommendation regarding further monitoring. But your risk of developing malignancy in another organ is probably higher. ...Read more

I had gastric bypass 2 weeks ago Would marijuana smoke do the same harm as cigarettes would to my new stomach?

I had gastric bypass 2 weeks ago Would marijuana smoke do the same harm as cigarettes would to my new stomach?

Not usually: tobacco smoke contains a number of substances that increase stomach acid and reduce the lower esophageal sphincter pressure, which increases reflux and esophagitis, while reducing the effectiveness of gastric mucous. Marijuana smoke does much less of this, but if you have had problems with peptic ulcer, gastritis or esophagitis, you are far better off not smoking ANYTHING. ...Read more

Can I do the duodenal switch with a BMI of 27.5? Had gastric bypass 7 yrs ago. Gaining weight again. I exercise, but my stomach fits a lot of food!

Can I do the duodenal switch with a BMI of 27.5? Had gastric bypass 7 yrs ago. Gaining weight again. I exercise, but my stomach fits a lot of food!

No: Duodenal switch will not work in a patient that has undergone gastric bypass, since the food stream no longer goes by way of the duodenum. If you are gaining weight after a gastric bypass, you should see your surgeon or a specialized GI physician, who can determine the cause for weight gain. This is usually due to enlargement of the connection between the stomach pouch and the intestine. ...Read more
