I can't comment on your bp readings, as I would imagine other risk factors have to taken into consideration, such as present long-term complications, family history etc. What I can say is that I am type 1, and have had retinopathy for some 10 years. About 3 years back I was put on low medication for bp to help prevent further complications with my eyes. This was despite having normal bp readings of around 130/70. Although my doctor said that for a non-diabetic this would be very satisfactory, he said the lower I could get my bp, would benefit my eyes and prevent other complications in the long-term.
At present my bp is 115-120/60-65 range, and some time back I bought a blood pressure monitor to test myself at home. These machines are so inexpensive now, you can buy them for as little as £10, and are great for getting a true bp reading. My readings are always lower at home than at my doctors, there is a condition called ''white coat syndrome'', this is where a person attending their doctors surgery is nervous and uptight, and therefore their bp is elevated and hence the higher readings. I get this and my doc says this is very common indeed.
At 33, and you seem to be pretty well active, may I suggest that you look at foods that help with lowering bp, oats are great for reducing bp, and I take a strong garlic supplement (Kwai one-a-day) to help with cholesterol and heart health. Google foods that reduce bp for further reccomendations. Long-term, the lower your bp, the less chance of strokes, heart disease, kidney damage, the list is endless. Hope all goes well and hope the above has been helpful.
