My father is not on diabetes medication except for BP (twintel 10/40) and prostrate (urimax f). His age is 80 years and physically active. My concern is that every time his fasting blood sugar remains higher (within normal limits) than his pp sugar. Examples are fasting 99, pp 88 (3 months back) and fasting 98, pp 87 (1 month back). Kindly advise. Thanks.
