@lauretta16, If you have a large hiatal hernia, I'm surprised that you don't have GERD/acid reflux. That seems to accompany a hiatal hernia everywhere I've seen. I have a sliding hiatal hernia, but I don't know if it is the cause of my SOB. It's always in the back of my mind that it could be the cause or a contributor but I'm just not sure. Regarding your anxiety/depression, you should enroll in a Cognitive Based Therapy program either in person or online. Very effective for long-term treatment of anxiety/depression. It will be one less thing to deal with, so you can focus on other aspects of your health like getting rid of the SOB. I too have been anemic though lately blood tests seem to show that I'm no longer anemic. If you take iron, it should be done carefully as your body can absorb too much iron which can cause problems. Take it with food to help alleviate the stomach issue. But do get tested again to see if the iron supplements are helping with the anaemia and to make sure your iron levels are right. It certainly wouldn't hurt to get tested for allergies. I think that will be my next step.
