My father age is 60 years old, he did not have bp issue but had some sort of
sugar flactuation. FBS- 136 mg/dL max. and PPBS - 140 mg/dL max. But he had not taken any medications. Today he had a good snack of peanuts and sugar less tea. Now at 8.00 p.m he says he is feeling discomfortness i.e he is feeling some sort of weakness/ increase in appetite suddenly. When checked with oxymeter his spo2 was 98% and HR was 90-95 bpm. What can be the reason for that?.
