Symptoms of GORD: feeling tired
BMJ Group Medical Reference
Having gastro-oesophageal reflux disease ( GORD) can affect your daily activities. Studies have found that people who have GORD say they don't have much energy. They often say they have to change their lives to deal with feeling tired.
Some studies have found that people who have symptoms of GORD most of the time can feel worse than people with arthritis, high blood pressure, mild heart failure or angina, or women going through the menopause. 
Angina is the name that doctors use for a pain in your chest that you get when your heart muscle isn't getting enough oxygen.
When the heart loses its ability to push enough blood through the blood vessels, it is called heart failure.
high blood pressure
Your blood pressure is considered to be high when it is above the accepted normal range. The usual limit for normal blood pressure is 140/90. If either the first (systolic) number is above 140 or the lower (diastolic) number is above 90, a person is considered to have high blood pressure. Doctors sometimes call high blood pressure 'hypertension'.
When a woman stops having periods, it is called the menopause. This usually happens around the age of 50.
