Have hiatal hernia. lately i'm having soft pale-colored stools that float, diarrhea, stomach pain, gas, nausea. are these symptoms related to hernias?

Some are: Stomach pain, gas, nausea could relate to hiatal hernia and coexist ant conditions(e.g. Reflux). Unlikely that diarrhea would be related to hiatus hernia.

No: These symptoms sound more like a gallbladder problem. Usually, hiatal hernias give you heartburn or acid reflux type symptoms. You should see a doctor and have this checked. Good luck!

Hiatal hernia: The hernia can cause malabsorption of fat which in turn can give you pale yellow stools that float and can be diarrhea in nature

No: These are not typical symptoms of having hiatal hernia. Most patient with hiatal hernia have problems with heartburn and symptoms related to reflux. Your symptoms sound more like they are related to irritable bowel disease except the pale colored stools. Hopefully, you are not jaundiced because that would indicate a more serious condition requiring examination by a physician.
