The outcome of this is I was diagnosed with GORD (Heartburn and gastro-oesophageal reflux disease).
From doing further reading into what GORD is, I found treatment is fairly easy as it mainly involves small life changes.
The following is extracted from the GORD information link.
"You may find the following measures can help reduce heartburn and other symptoms of GORD:
- Eat smaller and more frequent meals, rather than three large meals a day – don't eat or drink alcohol within three or four hours before going to bed, and avoid having your largest meal of the day in the evening.
- Avoid anything you think triggers your symptoms – common triggers include coffee, chocolate, tomatoes, alcohol, and fatty or spicy food.
- Don't wear tight clothing – clothes that are tight around your tummy may make your symptoms worse.
- Raise the head of your bed by up to 20cm (8 inches) – placing a piece of wood or blocks underneath one end of your bed may reduce symptoms at night; don't just use extra pillows, as this can put a strain on your tummy.
- Try to relax – stress can make heartburn and GORD worse, so learning relaxation techniques may help if you're often feeling stressed.
- Maintain a healthy weight – if you're overweight, losing weight may help reduce your symptoms.
- Stop smoking – smoke can irritate your digestive system and may make your symptoms worse.
Different medicines may be available, but don't stop taking any prescribed medication without consulting your GP first."
From looking at this, the action I need to take is eat smaller and more frequent meals. So this is my new years resolution to avoid the complications of GORD.
