Hi.
Thanks for your query.
Noted the history about a 70 year old male having intense desire of water in night, feel uncomfortable with increased heart beats, have to urgently take water, no stool for 2-3 days, then acidity and stomach twist, pass stool which brings
tiredness. Suffered
heart attack but okay with medicines since 2003...
Your history is suggestive of gastrointestinal disturbance, may be due to IBS or so.
I would advise you the following:
Since you are on medication for hear attack, it is possible that you have developed acidity. Hence it is better to take a course of a PPI like
Omeprazole, antacid and see the effects.
Avoid stress and
anxiety which too can cause or enhance such problems.
Since there is thirst in the night, this can be due to
diabetes and it is better to get the HbA1c and blood sugar levels.
Take the heart medicines regularly since you have increased heart beats in the night, get a review with a Cardiologist so that a proper alternation be done if required.
