    RENNIE AND ANATACIDS FAQ

      What are alginates?

      Alginates are active ingredients that form a protective layer on top of the stomach contents to help reduce acid reflux.

      What happens if I keep taking antacids for a long time?

      Antacids will only manage your symptoms rather than curing a problem. If your symptoms persist for longer than 14 days in a row you need to see your GP just to check there is no underlying cause.  Your doctor will be able to advise you on an ongoing management approach.

      What is the difference between heartburn & indigestion?

      Although people often use the terms interchangeably, there is a difference between heartburn and indigestion.

      Indigestion causes heartburn - the burning feeling or heat that begins in your chest or throat and occurs in waves. Most often this happens when acid from the stomach rises into the oesophagus and upwards to cause pain and discomfort.

      Indigestion is literally an ‘inefficient digestion’ and is a general term used for a collection of symptoms that include heartburn, but covers any pain or discomfort felt in the stomach region after meals. It is often triggered by eating or drinking things that make the stomach produce large amounts of acid, such as spicy foods or alcohol.
