The types of HT seen in DM are listed in Table 1. HT in IDDM is closely related to nephropathy. The earliest ,manifestation of the letter is in the form of microalbuminuria. Microalbuminuria is absent in the first 5-10 years, increases by 15-40% annually and overt nephropathy was noted in the past after 9-12 years of diabetes. However, presently it is on the decline. HT in IDDM preceeds or parallels microalbuminuria. It is seldom more than 160/95mm Hg. In those with DM of around 30 years duration, frequency of HT is 50 percent. HT is rare without nephropathy. Familial HT is 4 times more common in those with HT and nephropathy. Table 1 Hypertension in Diabetes
