What is indigestion?

Indigestion, also known as dyspepsia, is a general term for pain or discomfort felt after meals in the stomach region, associated with difficulty in digesting food. It can strike at any time, but is most common shortly after eating.

Indigestion is very normal and most people will experience it at some point. You could suffer a couple of times a year or feel symptoms regularly. The discomfort or pain of indigestion can range from mild to severe and can last for a few minutes to several unhappy hours.

Unfortunately, indigestion can be unavoidable during pregnancy as the body changes hormonally and physically.

What causes indigestion?

When you eat, your stomach produces acid. Indigestion is often caused by excess stomach acid coming into contact with the sensitive, protective lining of the stomach, the top part of the bowel, or the oesophagus, which can cause soreness and swelling. This produces a feeling of discomfort which can feel like a ‘fire in your belly’, particularly if your digestive lining is especially sensitive to acid.

We all experience indigestion differently, and its triggers are different for each of us. Try looking out for patterns in what you eat and when you suffer. Other common causes are:

  • 1) Drinking alcohol

    alcohol causes your stomach to produce more acid than normal, which can irritate your stomach lining.
  • 2) Smoking

    the chemicals in the smoke can cause the muscle between the oesophagus and stomach to relax, allowing acid to escape in to the digestive system.
  • 3) A busy stressful lifestyle

    symptoms of indigestion usually increase in times of stress, and get better when you’re relaxed. Stress and anxiety can have a huge impact on our digestion, leading to an increased production of stomach acid.
  • 4) Eating heavy meals or fatty foods

    can irritate the belly. Eating too fast also encourages indigestion.

Persistent indigestion sometimes occurs as a result of an ulcer, taking certain medications, or another condition. If you think this might be you, make an appointment with your GP.

Heartburn triggers

Heartburn is an extremely uncomfortable experience that affects thousands of people across Ireland on a daily basis.

Also known as acid reflux, heartburn is a burning sensation in the chest that occurs as a result of stomach acid rising up into the oesophagus.
