I have acid reflux/gerd I feel fatigued alot I have figured out it is the acid so I take antacid and it goes away I feel dizzy to sometimes so I stop walking and just stop for a second and it goes away
Did this start after starting the Omeprazole OR have you been on the Omeprazole then this started?
I would definitely recommend seeking medical attention ASAP for this.
Omeprazole can cause these symptoms OR can make these symptoms related to something else worse.
Seek medical attention and get this sorted ASAP.
I am aware that a flu is going round, so not sure if u have a touch of that, if this continues u should see ur PCP and get checked to see what is going on.
