The elderly are more prone to acid reflux and tend to have more problems with reflux than younger adults.

As we age the amount of saliva production decreases. Saliva is an antacid in its own right. Reduced saliva means reflux from the stomach could stay longer in the esophagus and potentially cause more harm. In addition swallowing may not be so easy since saliva lubricates food for smooth passage downwards.

As we age, there is an increased risk of developing a hiatus hernia. A hiatus hernia can affect the sphincter and cause acid reflux.

Natural weakness of muscles occur with age. The muscles of the esophagus and the bowels weaken leading to weaker peristaltic contractions. This cause slower clearance of food from the esophagus and the large bowel. Constipation is common in the elderly. Constipation can cause straining. Straining raises the intra-abdominal pressure and may cause the stomach content to reflux up into the esophagus.

There is an increased risk of other illnesses such as hypothyroidism and diabetes. These illnesses increase the risk of GERD.

Generally the elderly are more likely to lead a sedentary life or at times become confined to bed. Lying down is not good for acid reflux.

The elderly tend to accept acid reflux as part of the ageing process and wait longer before getting adequate acid control. In addition they may be on various medications that can aggravate acid reflux.
