I have acid reflux and a newly found small hiatal hernia, if i am careful can i still shovel snow?

Yes you can: Acid reflux (gerd) is a common condition, and often associated with a hiatal hernia. Lifestyle modifications are recommended, including reduction of caffeine, alcohol, chocolate, spicy foods, and elevation of the head of your bed. Sometimes tight waistbands can increase abdominal pressure and worsen the symptom. Shoveling snow shouldn't bother you if done calmly and occasionally. Good luck!

Yes: You can do all of your normal activities with a small hiatal hernia without fear of making it worse. It can enlarge over time, but this usually takes years, and is probably independent of your activity. There are obviously exceptions to every rule, but you should be ok to shovel snow.
