Hello lesleyarkinson,
Feeling of
tiredness and lack of energy may indicate that your blood count
is low. This may be due to slow blood loss from the digestive tract. Since you
do mention stomach problems and
heartburn symptoms , the two could be
related. I would recommend that you first have blood tests including complete
blood count, iron levels and also have your stool tested for hidden blood.
If you have not had an X-ray of the
esophagus and stomach, you should
get that. (Upper GI series). After that ,depending on results you may need
an endoscoppic examination of your stomach with a
biopsy.
Temporarily for relief, instead of
gaviscon, try over the counter Omeprazole
20 mg. twice a day an hour before meals.
Wish you well.
