ความดันโลหิตสูง
ผนังภายในของเส้นหลอดเลือดของชาวสูงวัย จะเต็มไปด้วยเศษสิ่งต่าง ๆ จากสิ่งตกค้างที่ถูกลำเลียงผ่านเส้นเลือดนั้น เช่น เศษไขมัน เป็นต้น ครับ...
ซึ่งก็จะทำให้รูหลอดเลือดแคบลง เมื่อแคบลงแล้ว ก็จะทำให้ปริมาณน้ำเลือดที่ไหลไปยังอวัยวะปลายทางลดลง ร่างกายจึงปรับตัวโดยการเพิ่มแรงบีบของหัวใจ เพื่อให้เกิดแรงดันในหลอดเลือดเพิ่มสูงขึ้น อวัยวะปลายทางจึงจะได้น้ำเลือดไปหล่อเลี้ยงเพียงพอครับ...
ความดันโลหิตสูง จึงเกิดขึ้น และเป็นมากขึ้น ในผู้สูงวัยครับ...
ลดของเค็มลงให้มากที่สุดนะครับ เพราะความเค็ม จะเพิ่มความดันโลหิตครับ... และพบหมอเพื่อรับการดูแลรักษานะครับ...
ความดันโลหิตสูงนี้ อันตรายมากเลยทีเดียวนะครับ...

I think we should approach our health issues from inquiry rather than I told you so because of the ways our body [systems] work inter-dependently [among organs and systems]. Seeing doctors is a good and safe advice but how many doctors have time to focus on your specific case? The responsibility for our health is ultimately ourselves. To take the responsibility seriously, we have to __observe, ask questions, find answers, test and modify our ‘solutions’ [behaviour], then repeat the process – until we understand all or die!
[Some examples of information from the Internet ]A high salt diet disrupts the natural sodium balance in the body. This causes fluid retention which increases the pressure exerted by the blood against blood vessel walls (high blood pressure).
…low sodium levels in the body can lead to muscle cramps, nausea, vomiting and dizziness. Eventually, lack of salt can lead to shock, coma and death. Severe salt loss is very unlikely to happen because our diets contain more than enough salt.
Drinking water can help normalize your blood pressure but doesn’t necessarily lower your blood pressure unless you are dehydrated. Because your blood is made up of 90% water, the overall volume will decrease when you are dehydrated.
But what if salt isn’t the main culprit? Framed by another common ingredient? It turns out sugar could be the biggest cause of high blood pressure. https://www.webmd.com/hypertension-high-blood-pressure/video/sugar-vs-salt-whats-worse-for-blood-pressure : Don’t fear! Natural sugar in fruits and vegetables is fine. It’s excess amounts of added sugars to watch out for – especially, high fructose corn syrup. Let’s take a closer look. According to a new study, drinking 24 ounces of soda can cause a jump in your blood pressure. And if 25 percent of your daily calories come from added sugar, you almost triple your chances of cardiovascular disease compared to people whose intake is less than 10 percent. The best way to avoid this? Stay away from processed foods, and eat a heart-healthy diet.
https://www.bloodpressureuk.org/your-blood-pressure/how-to-lower-your-blood-pressure/healthy-eating/salt-and-your-blood-pressure/ : Adults should eat less than 6g[-8g] of salt a day [1 level teaspoon max]
[I want to mention that though our body has many effective balancing controls and for most of us these systems work to keep us healthy. But the diet and life style we [collectively] choose –in disregard to our body systems [evolved through many many millions of years] – are at present the main suspects for our ill-health.
And as we have more to interact, we have less understanding of how things work. In our busy life, we pray and hope for the best. So, we are happier but not wiser. ]
Sir, my writing potential mostly like the story teller, these are low academic support. Therefor, your comments are necessary to complete for notes. Thus, thank you very much for your kindly take notes. I am almost agree with you, thanks again.
Can we look at https://www.oecd.org/publication/pisa-2022-results/country-notes/thailand-6138f4af/
(If ‘no time to read the whole report’ then just look at
- Figure 2. Mean performance in mathematics, reading and science in PISA 2022
- Figure 3. Top performers and low-performing students in mathematics, reading and science.)
Shall we do something about this? Can we help? What is a good way to help?…
