Hypertension is a greater risk factor in diabetics than in non-diabetics.
Even stricter control may be necessary in younger patients with early nephropathy. In diabetic patients hypertension may have different causes, most commonly essential hypertension and nephropathy. Thereafter drugs which do not interfere with the treatment of diabetes should be used. Combinations of drugs may be used. The choice of anti-hypertensive drug will be influenced by concomitant disease e.g. myocardial ischaemia, congestive cardiac failure.
