Last few times we have been on strenuous walks (last one was yesterday), DH has to stop with chest pains and dizziness. However he has had what seems to be indigestion almost constantly for the last 4/5 days. We've been on holiday and he has been almost continuously belching, farting, and complaining of his stomach feeling tight.
Is it his digestion or is it something more serious?
He is overweight and tends to chomp his meals which I have told him about- just slow down and chew properly - he guzzles as if he needs to catch a bus!
