Hi well I have reflux and asthma. Im finding it hard to stay away from tea and coffee. I get regular flare ups. Fortunately it doesn't affect my asthma but I can get coughing. We are suposed to stay off caffeine drinks. How can you do it though when pop isn't good either or alcohol? Theres not much else to drink as chocolate isn't good either. Its not very nice just to have water. I don't know what the answer is. I have a hiatus hernia and so want that fixed then I may be ok I don't know. Keep up your meds especially for asthma.
Yes, black tea can aggravate reflux and yes reflux can aggravate pre-existing Asthma or cause "Asthma-like" symptoms. In fact, black tea contains more caffeine then coffee.
Best to stay away for ANYTHING caffeinated.
