Acid reflux is caused by a weakness in the musculature at the lower end of the food pipe and in the stomach being weak. There is actually no valve per se as there is for example in the bladder or at the other end of the stomach before the duodenum. The muscles of the oesophagus act as a partial valve. If the acid in the stomach travels up the oesophagus, it is due to either a hiatus hernia , an over- filling of the stomach or intra-abdominal fat putting pressure on the stomach contents.
The symptoms are usually a burning sensation or, less commonly, a tightness felt at the top of the abdomen or behind the sternum. The burning can extend into the throat.
Acid reflux occurs when acid from the stomach travels up the oesophagus. The resulting burning sensation is known as heartburn.
Consult your GP if the symptoms persist.
The occasional use of antacids is not unwarranted.
The homeopathic remedies Nux vomica, Carbo vegetans, Lycopodium and Arsenicum should be reviewed in your homeopathic manual.
Milk may give immediate relief but it stimulates acid production and can worsen the condition if taken persistently.
