My mom's sugar is high today what can she do to lower it instead of going to the ER?

So she is hyperglycemic? How high is she running? There are natural remedies online that seem to work, just depends on the duration of running high and how high of glucose levels she is running. Nuts and water are great to lower GI (glucose intake), and one of the first things the ER would do is hydrate her with fluids (more likely). Hope this helps

I would still take here to the E.R., it could be something else other than her sugar.

Nothing that i can prescribe always better to seek medical help
