Jab Mein Thaa, Tab Guru Nahin‚ Aub Guru Hai, Mein NahinSabAndhiyaraMit Gaya‚ Jab Deepak DekhyaMahin When "I“, the Ego, was with me, then I couldn’t realize the almighty within; Now, the Almighty "is" ever with me and there is no place for this Ego. All the darkness (illusion) within me is mitigated, on realizing the light (illumination) within. SK

How Common is this Duo? HTN is twice as common in DM New onset DM is 2.5 times in HTN 20 to 40% of IGT pts have HTN 40 to 50% of Type 2 DM have HTN Only 1/4 of HTN in DM is controlled DM + HTN – CV Risk 3 fold
What Causes HTN in DM • Metabolic Syndrome – Mainly IR, ED, BG • Excessive RAAS activity is the main mechanism • HTN due to nephropathy in T2DM – GS - KWL • Renal scarring - Recurrent pyelonephritis • Endocrine causes for both HTN & DM • Cushing’s, Conn’s, Pheochromo, Acromegaly • Coincidental – DM on existing HTN • Diabetogenic antihypertensive drugs (D and B) • Drugs causing both HTN & DM – OCP, CS
Relative Risk of DM + HTN Diabetes + HTN versus Diabetes • Neuropathy 1.6 • Nephropathy 2.0 • Retinopathy 2.0 • Stroke 4.0 • CHD 3.0 • Mortality 2.0
Difficulties of HTN in DM • Systolic HTN more common in DM • S-HTN is a stronger predictor of CVE • 65% of T2DM have S-HTN • S-HTN is more difficult to control • Depression is more in DM – Adherence Rx • ‘Clinician Inertia’ is a big problem • Glycemic control only is the focus – No VP

HTN – Lifestyle modifications • Regular 30’ of moderately intense exercise • No tobacco and minimizing alcohol • Na restriction to < 6 g of Nacl per day • Avoiding high salt foods – pickles, savouries • Four adult family – 6 x 30 x 4 = 720 g (500 g) • Use of K containing foods – fruits, vegetables • Weight reduction – goal ideal weight • Reducing coffee consumption
