Unfortunately hypertension can cause great damage if left untreated for a long time: kidney disease and heart disease most obviously but from my understanding, any organ that has blood vessels can be affected and damaged, including brain, eyes, liver, lungs... The OP is not catastrophising, but trying to be pragmatic (although I hope that with treatment they will be able to live as long as they would have without the…

As a hypertension sufferer I know the harm it can cause but as a 140/100 for over twenty five years aged 59 with intermittent treatment, I'm struggling with the idea it's an imminent problem in and of itself compared to eg untreated 160/120 or worse. Reading around, health standards vary by economy. Maybe australia has a different cutoff bp to the USA. The nih say you need five visits to be assessed on 140/100. Many…

Reading the OP's comment again, they did not talk of an "imminent demise". They said that their genetics "puts a cap" on their "life expectancy". Hence my own comment about hypertension causing damage if left untreated "for a long time".

Can confirm. I cook a salt-free cuisine for my relative [1] who has kidney disease and must aggressively control their blood pressure and I can go entire months without eating anything with any salt at all. There was a bit of an adjustment to be had in the first few months, from what I recall, but I was surprised to what degree my taste buds adjusted after a while. Nowadays, I can't enjoy normally salted food because…

Maybe I wasn't looking hard enough for butter. I was mainly using it for cooking and ended up using olive oil for most things. I used to have a bread machine, and bread seemed to bake just fine without salt. Store bought bread without salt was impossible to find.

Well, olive oil is supposed to be better anyway. Although it seems to me that everytime I find a study that claims health benefits from olive oil consumption it's conducted by a Spanish or Greek university (I'm Greek btw, so made of ~80% olive oil).

I can find salt-free bread from local bakeries in Greece. Also, salt-free rusks (popular in Greece) seem to be a trend, there's three or four different brands that sell them in supermarkets.

> It's a chore that takes minimum 10 minutes twice a day 10 minutes sounds like a lot, I have a pretty common OMRON automatic pressure measuring device[0], and it takes about a minute to do the actual measuring, plus, say, another two to take off my sweater and put it back on. I suppose I am missing something, how come it takes much longer for you? EDIT: have you tried meditation? As a fellow person with genetic disp…

>> I suppose I am missing something, how come it takes much longer for you? Not the OP, but at a guess (one of my relatives has kidney disease and take their blood pressure twice a day every day), it takes about 5' to relax, then another 5' to take two readings and combine the results. My relative takes three readings and keeps the last. From my understanding this is common with electronic devices, where the measured…

ah, that makes sense, thank you.

I used to take multiple readings too, but then concluded it was somewhat pointless: my measurements seem to be pretty consistent, and I would only be alerted when I noticed a shift over multiple days, but I understand how this can vary by person.

> It was actually a bit depressing to see how much stuff is available, just not available in the US One reason for this is strict regulations. U.S. FDA Title 21 CFR Part 11 is very strict as to what a medical device company needs to do, and it's not easy to meet those requirements. Most people do not realize that even in the early startup stage, if you build something that is a medical device, there are rules to foll…

I would be interested in knowing more about the tradeoffs between their system and ours, if you could expand a bit?

What do you mean by "their system"?

Similar restrictions exist in the EU, Canada and Japan — I'm not familiar with the rest of the world. I suspect developing new products in China is much easier, and you can showcase them anywhere.

I think they are just saying the data is more likely to be secure if it is recorded at your doctor's office, which seems reasonable to me. Let's say it is a blood pressure reading taken by your Fitbit and uploaded to Google's servers. That data is not subject to HIPAA regulations. When your doctor takes your blood pressure and records it in your chart, it is subject to those regulations (as you say, it would be wildl…

"Separately, even if the two scenarios were subject to the same regulations, I would still expect the doctor's office scenario to be more secure. I think that any given patient's home network/device/security practices are more lax than those of most healthcare organizations." For the most part security for healthcare systems is like security for government systems. A lot of checkbox marking and little real security.…

Yeah that’s fair, I do think organizational ineptitude is a concern. I guess it’s just different threat models. A medical office has locking file cabinets, password-protected devices/networks, more robust building security, the standards of hipaa, etc. (granted all of those are subject to proper implementation)

If I needed to get one person’s medical information, I think I’d I have a higher likelihood of getting it from their medicine cabinet or snooping on their devices or search history.

If I needed the information of many people, I’d target the doctor. But even then, the goal typically isn’t to leak anyone’s information, it’s to get money from the healthcare provider and the information stays secret, theoretically.

Not really disagreeing with you just rambling.
