Hi, thanks for posting the concern in HCM.
As you have posted, your husband had carbonated beverage at empty stomach and developed nausea, pain in back and hand and had a faint like feeling.
Now, you want to know reason behind the same.
This needs evaluation for any cardiac problem like ischaemic
heart disease and ACS, or gi problem like Gastritis etc. For that the following tests are needed.
Ecg,
Complete blood count, urea,
creatinine, electrolytes
If Ecg is normal, TMT may be done.
Your assumption may be partially correct. Carbonated beverages in empty stomach can cause bloating, stomach distension and autonomic response.
UGI endoscopy may also be needed to rule out
acid peptic disease and
peptic ulcer.
Therefore, urgent evaluation is needed by a physician along with the above mentioned tests.
In case you have any other questions, please write back.
Regards
Dr Kaushik Sarkar
