I am Swapnil Das 21 years old and my lower diastolic bp always reads low, going as low as 45 sometimes but mostly staying with 50-55mmhg range with the systolic pressure mostly within 120-125mmhg. I am currently under medications daily- Amlodipine 10, Levamisole 100mg(alternate days), Avas 20, Telmisartan 40 amd Ecospirin 75. I feel so light headed after I get up from sitting postures mostly during the day. I had coarctoplasty 3 years back in 2018 and I have nephritis (1FRNS). Do i need to get concerned about this or is it normal?
