[|Human|] Hello my nan keeps complaining of having gas around her heart which resolves to her going light headed and dizzy.She is 77 and has had a operation on her heart and had a new valve.She tells her doctor but wont do anything and Im concerned as it makes her go dizzy and she is not stable on her feet as it is. Can you help what is causing this and anything what could help.Thank you
[|AI|]  Hello, I passed carefully through your question and would explain that it is necessary evaluate her heart function and exclude possible heart failure, which may mimic this clinical situation.Gastroesophageal reflux may mimic this situation too, although the dizziness is not typical of this disorder. Coming to this point, I would recommend performing a cardiac ultrasound and NT-pro BNP levels to investigate for heart failure. Other tests to consider would be:- A chest X-ray study-Blood electrolytes- Kidney and liver function tests would also recommend trying an anti-acid or PPI (Omeprazole, Pantoprazole, et cetera). If her symptoms improve, a fibro-gastroscopy may be necessary. Hope I have answered your query. Let me know if I can assist you further.
