I am a diabetic patient for last 20 years. I am taking medicine a) dianorm-m and vingyle-50 after food, b) storvas-10 once daily, and c) losartan-20 one daily for blood pressure. For the last one month, I am suffering from stomach problem (bubbling sound in the stomach after food) and getting burning sensation in the chest. Recently I have done a blood test which is reported as follows:- a) glucose postprandial - 175 b) fasting blood sugar - 88 c) haemoglobin a1c [hba1c] - 6.2 d) creatinine - 0.9 e) sodium - 133 f) potassium - 5.8 what is the treatment for stomach problem i.e. Bubbling sound, and burning sensation in chest? Is the potassium level fine or it should be lowered?
