Conversation: The conversation between human and AI assistant.
[|Human|] Tonight I was a restaurant outside and after eating I felt lightheaded and did pass out. This has happened before and my blood pressure was low. Not sure about tonight. I am female 59 years old and in pretty good shape. Didn t eat much today and had a wine sangria before dinner didn t know if potassium or magnesium might also cause this type of symptom. There was a nurse their and kept telling me this is not normal
[|AI|]  Hello! Your symptoms could be related to postprandial hypotension. This disorder can be related to autonomic nervous system dysfunction. The changes in blood electrolytes can lead to cardiac arrhythmia, but they are not related to eating (symptoms occurring after eating are not explained by these changes). I would recommend consulting with your attending physician for a careful physical exam and some tests: - a resting ECG- a chest X-ray study- a Head Up tilt test-some blood lab tests (complete blood count, fasting glucose, blood electrolytes). I would also recommend performing a fibro-gastroscopy if these symptoms persist, or you have other gastrointestinal symptoms to exclude possible hiatal hernia. Meanwhile, I would recommend avoid large meals, hypercaloric meals and try to eat more frequently during the day in small portions, in order to avoid distension of your stomach and blood sugar overload. Hope to have been helpful! Best wishes,
