Much better would be to eliminate the high blood pressure.

Most high blood pressure, at least in UK and its former colonies (US particularly included), is a product of uric acid poisoning, itself caused mainly by the massive excess of sugar pumped into stuff sold as if it were food. (Excess alcohol has identical effect.) Cut stuff with sugar added from your diet, and take up exercise, and your blood pressure comes down.

Excess uric acid also causes most type-2 diabetes.

I never considered doing a tattoo, but this looks like a great idea. As for decorative tattoos, I'll wait for e-paper version, so I can change it when I want to. And yes I know this beats the purpose of a tattoo being something permanent, but, if I ever do something like that, I'll be forever an Etch-a-Sketch

That would be cool but can I ask what makes you think it's something that will ever actually exist? Or do you just mean that regardless of whether or not it ever exists, it's the only thing that would result in you getting a tattoo?

Thank you. I discovered I have an adrenal nodule via another medical investigation. No one has ever suggested it might be linked to my high blood pressure.

Here's a story of a gentleman whose blood pressure issues were cured once they removed the offending adrenal gland. https://www.washingtonpost.com/health/2022/04/23/high-blood-...

If you do find out you have a high Aldosterone/Renin ratio, join this Facebook group

Conn's Syndrome / Hyperaldosteronism Support Group

https://www.facebook.com/groups/652067311558303

They're very supportive with personal stories, what has worked for others, and guidance with the whole process of getting diagnosed with Primary Aldosteronism.

I'm sure parts of the body mod/biohacking community are already working on it. People are already doing things like embedding RFID into their hands. When I read the headline I thought they had somehow managed to get an actual tattoo to respond to blood pressure changes through the pressure itself, similar to how the cells in Octopi change colour.

my actual tattoo reacts to something (allergens?) occasionally and raises up (I can feel the lines when i touch it). i can imagine that an electronic tattoo of some sort would feel really strange. I almost embedded an RFID a few years back but chickened out.

I read that as “I embedded an RFID in a chicken”.

Reminds me I went to a dairy the other week where chipped cows trigger feeding and milking bots for detailed monitoring, dietary microadjustments, etc. I’ll see if there’s info worth posting.

Livestock seems like it would be the place to start with permanent medical data implants, including batteries and a computer.

Just to share another data point, I had similar numbers several years ago and tried the same thing, didnt want to take meds so made significant changes to my diet and exercise. My cholesterol was getting to the point of needing medication too. I dropped something like 20-30 lbs, cut out a lot of carbs and most sugar. Felt great, but my bp and cholesterol numbers didnt move at all. started meds for both and theyre bot…

Thanks for sharing. That's why I was careful to label it as personal anecdata. I don't want to assume it works for everyone. But I believe losing weight is a good first step/test if you want to avoid taking meds.

there is a catch 22 with some meds, like lisinopril, which can make you gain weight..my doctor told me If I lost 15-20 pounds my BP would drop, but it's the lisinopril that made me gain that weight

My personal anecdata, I would like to share: I developed blood pressure problems last year (140-160/85-95). My doc told me I needed to start meds. I didn't want to though. So in January, I started reducing my Caloric intake. I lost 7 kilos, down from 83kg to 76kg (I am 1.70m tall). My blood pressure went down to (110-120/60-75). No meds required. Just ate less.

Note that "cholesterol getting to the point of needing medication" is not a thing.

The statin pushers tried for decades to demonstrate that statins do any good for people not in imminent danger of (another) heart attack. They have failed. So, instead, they hector physicians to prescribe statins when they find a slightly "elevated" level of LDLs. Your body needs cholesterol, and makes exactly as much as it needs. If your level is "elevated", you are doing something that makes you need to make more. Suppressing it means you don't have enough.

If you worry about an elevated LDL level, the best response is to cut sugar intake.

Works for some. I have family members with no excess body weight - bmi in the single digits - and high blood pressure. There are like 50 variables. Weight is a big one, but not the only one.

For most Americans the main cause of high blood pressure is excess uric acid, itself a product of excess sugar intake. Advanced imitation food substitute producers pack sugar into practically everything nowadays. It is hard to avoid it when buying anything processed.

Did you change your micronutrient makeup, or reduce sodium more than proportionately to the caloric drop?

Sugar intake is more important than salt, as a cause of high blood pressure.

> The device takes its measurements by shooting an electrical current into the skin and then analyzing the body’s response, which is known as bioimpedance. There is a correlation between bioimpedance and changes in blood pressure that has to do with blood volume changes. However, the correlation is not particularly obvious, so the team had to create a machine learning model to analyze the connection to get accurate b…

The article said "researchers at The University of Texas at Austin and Texas A&M University have developed an electronic tattoo that,..., and deliver continuous blood pressure measurements at an accuracy level exceeding nearly all available options on the market today". But yeah they didn't dive into specifics.

“0.2 ± 4.5 mm Hg for diastolic pressures and 0.2 ± 5.8 mm Hg for systolic pressures, a performance equivalent to Grade A classification” per the Nature abstract linked in the article: https://www.nature.com/articles/s41565-022-01145-w

You could probably calibrate it to each person, and maybe recalibrate every couple months. Still leaves you with a bunch of factors, but maybe those can be controlled for (measuring skin conductivity in addition to impedance?).

Sounds prone to errors from moisture, activity, salt, and all kinds of things.

A direct proxy to BP seems valuable, could save many lives. I agree we'll want clinical studies to validate how precise/accurate this measurement is.
