[|Human|] I am 63 with history of coronary heart disease and diabetes, for some time I have been suffering frequent days of nausea, sometimes physically sick and light headednes. My doctor put me on a course of tablets to supress acid, which helped but I am still suffering albeit less often.
[|AI|]  Hello, It looks like acidity problem only. Also, you check your blood pressure frequently and maintain the chart. Sometimes low BP also lead to same. Try to take pulse rate reading during lightheadedness, it shouldn't be very high like 140-150. Avoid spicy and fatty foods. Avoid smoking and alcohol if any. Also maintain sleep habits regular and also do regular exercises. Have some walk after meals instead of taking rest immediately. You can take acid suppressant like tab pantoprazole. Hope I have answered your query. Let me know if I can assist you further.
