If u have GERD and just had the flu...that all makes sense.
R u on ne GERD meds...other then the tums?
There r many things u can do to help....one, talk to ur Dr about taking a probiotic to get ur digestive track back in balance.
Avoid foods and bevs that will trigger GERD.
Greasy ,spicy, acidic foods, carbonated bevs, and those with caffeine.
We do have a GERD forum and the Health Pages have tips on how to modify ur diet and lifestyle...all of which will help GERD symptoms.
