Hi welcome to Healthcare magic forum. Now you child of 8 years is feeling difficulty during night, she told it is only an acid reflux
. Don't worry she is right it is only an indigestion
. caused by some foods. Other causes are amoebic infection or worms in the stomach. You need not worry, what ever it is curable.
She had kidney
reflux as a child , that is a different thing and it has nothing to do with the present acid reflux. that is due to diversion of the mood towards games etc, post poning the urination it happens. The remedy is to make habit of urination frequently.
For the present problem i advise you some diet recommendations for her. Avoid giving excess of spices , chillies, junk foods, oily foods, citrous fruits, and juices.
give more of green leafy vegetables, pulses, sprouts, milk, egg, meat, fleshy fruits , juices, and dry fruits. Wishing for a quick recovery and thanks for calling.
