Top 10 Causes Of High Blood Pressure

As Dr. Frita Fisher explains, these are actually the top 10 known causes of high blood pressure. Number zero on the list would be “primary hypertension”, which means high blood pressure with no clear underlying cause.

Superficially, this feels a little like the sometime practice of writing the catch-all “heart failure” as the cause of death on a death certificate, because yes, that heart sure did stop beating. But in reality, primary hypertension is most likely often caused by such things as unmanaged chronic stress—something that doesn’t show up on most health screenings.

Dr. Fisher’s Top 10

  • Thyroid disease: both hyperthyroidism and hypothyroidism can cause high blood pressure.
  • Obstructive sleep apnea: characterized by snoring, daytime sleepiness, and headaches, this condition can lead to hypertension.
  • Chronic kidney disease: diseases ranging from diabetic nephropathy to renal vascular disease can cause high blood pressure.
  • Elevated cortisol levels: conditions like Cushing’s syndrome or disease, which involve high cortisol levels, can lead to hypertension—as can a lifestyle with a lot of chronic stress, but that’s less readily diagnosed as such than something one can tell from a blood test.
  • Elevated aldosterone levels: excess aldosterone from the adrenal glands causes the body to retain salt and water, increasing blood pressure, because more stuff = more pressure.
  • Brain tumor: tumors that increase intracranial pressure can cause a rise in blood pressure to ensure adequate brain perfusion. In these cases, the hypertension is keeping you alive—unless it kills you first. If this seems like a strange bodily response, remember that our bodily response to an infection is often fever, to kill off the infection which can’t survive at such high temperatures (but neither can we, so it becomes a game of chicken with our life on the line), so sometimes our body does kill us with one thing while trying to save us from another.
  • Coarctation of the aorta: this congenital heart defect results in narrowing of the aorta, leading to hypertension, especially in the upper body.
  • Pregnancy: pregnancy can either induce or worsen existing hypertension.
  • Obesity: excess weight increases blood flow and pressure on arteries, raising the risk of hypertension and associated conditions, e.g. diabetes etc.
  • Drugs: certain medications and recreational drugs (including, counterintuitively, alcohol!) can elevate blood pressure.

  • How Much Can Hypnotherapy Really Do?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Sit Back, Relax, And…

    In Tuesday’s newsletter, we asked you for your opinions of hypnotherapy, and got the above-depicted, below-described, set of responses:

    • About 58% said “It is a good, evidenced-based practice that can help alleviate many conditions”
    • Exactly 25% said “It is a scam and sham and/or wishful thinking at best, and should be avoided by all”
    • About 13% said “It works only for those who are particularly suggestible—but it does work for them”
    • One (1) person said “It is useful only for brain-centric conditions e.g. addictions, anxiety, phobias, etc”

    So what does the science say?

    Hypnotherapy is all in the patient’s head: True or False?

    True! But guess which part of your body controls much of the rest of it.

    So while hypnotherapy may be “all in the head”, its effects are not.

    Since placebo effect, nocebo effect, and psychosomatic effect in general are well-documented, it’s quite safe to say at the very least that hypnotherapy thus “may be useful”.

    Which prompts the question…

    Hypnotherapy is just placebo: True or False?

    False, probably. At the very least, if it’s placebo, it’s an unusually effective placebo.

    And yes, even though testing against placebo is considered a good method of doing randomized controlled trials, some placebos are definitely better than others. If a placebo starts giving results much better than other placebos, is it still a placebo? Possibly a philosophical question whose answer may be rooted in semantics, but happily we do have a more useful answer…

    Here’s an interesting paper which: a) begins its abstract with the strong, unequivocal statement “Hypnosis has proven clinical utility”, and b) goes on to examine the changes in neural activity during hypnosis:

    Brain Activity and Functional Connectivity Associated with Hypnosis

    It works only for the very suggestible: True or False?

    False, broadly. As with any medical and/or therapeutic procedure, a patient’s expectations can affect the treatment outcome.

    And, especially worthy of note, a patient’s level of engagement will vastly affect it treatment that has patient involvement. So for example, if a doctor prescribes a patient pills, which the patient does not think will work, so the patient takes them intermittently, because they’re slow to get the prescription refilled, etc, then surprise, the pills won’t get as good results (since they’re often not being taken).

    How this plays out in hypnotherapy: because hypnotherapy is a guided process, part of its efficacy relies on the patient following instructions. If the hypnotherapist guides the patient’s mind, and internally the patient is just going “nope nope nope, what a lot of rubbish” then of course it will not work, just like if you ask for directions in the street and then ignore them, you won’t get to where you want to be.

    For those who didn’t click on the above link by the way, you might want to go back and have a look at it, because it included groups of individuals with “high/low hypnotizability” per several ways of scoring such.

    It works only for brain-centric things, e.g. addictions, anxieties, phobias, etc: True or False?

    False—but it is better at those. Here for example is the UK’s Royal College of Psychiatrists’ information page, and if you go to “What conditions can hypnotherapy help to treat”, you’ll see two broad categories; the first is almost entirely brain-stuff; the second is more varied, and includes pain relief of various kinds, burn care, cancer treatment side effects, and even menopause symptoms. Finally, warts and other various skin conditions get their own (positive) mention, per “this is possible through the positive effects hypnosis has on the immune system”:

  • Why Adult ADHD Often Leads To Anxiety & Depression

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    ADHD’s Knock-On Effects On Mental Health

    We’ve written before about ADHD in adult life, often late-diagnosed because it’s not quite what people think it is:

    ADHD… As An Adult?

    In women in particular, it can get missed and/or misdiagnosed:

    Miss Diagnosis: Anxiety, ADHD, & Women

    …but what we’re really here to talk about today is:

    It’s the comorbidities that get you

    When it comes to physical health conditions:

    • if you have one serious condition, it will (usually) be taken seriously
    • if you have two, they will still be taken seriously, but people (friends and family members, as well as yes, medical professionals) will start to back off, as it starts to get too complicated for comfort
    • if you have three, people will think you are making at least one of them up for attention now
    • if you have more than three, you are considered a hypochondriac and pathological liar

    Yet, the reality is: having one serious condition increases your chances of having others, and this chance-increasing feature compounds with each extra condition.

    Illustrative example: you have fibromyalgia (ouch) which makes it difficult for you to exercise much, shop around when grocery shopping, and do much cooking at home. You do your best, but your diet slips and it’s hard to care when you just want the pain to stop; you put on some weight, and get diagnosed with metabolic syndrome, which in time becomes diabetes with high cardiovascular risk factors. Your diabetes is immunocompromising; you get COVID and find it’s now Long COVID, which brings about Chronic Fatigue Syndrome, when you barely had the spoons to function in the first place. At this point you’ve lost count of conditions and are just trying to get through the day.

    If this is you, by the way, we hope at least something in the following might ease things for you a bit:

    It’s the same for mental health

    In the case of ADHD as a common starting point (because it’s quite common, may or may not be diagnosed until later in life, and doesn’t require any external cause to appear), it is very common that it will lead to anxiety and/or depression, to the point that it’s perhaps more common to also have one or more of them than not, if you have ADHD.

    (Of course, anxiety and/or depression can both pop up for completely unrelated reasons too, and those reasons may be physiological, environmental, or a combination of the above).

    Why?

    Because all the good advice that goes for good mental health (and/or life in general), gets harder to actuate when one had ADHD.

    • “Strong habits are the core of a good life”, but good luck with that if your brain doesn’t register dopamine in the same way as most people’s do, making intentional habit-forming harder on a physiological level.
    • “Plan things carefully and stick to the plan”, but good luck with that if you are neurologically impeded from forming plans.
    • “Just do it”, but oops you have the tendency-to-overcommitment disorder and now you are seriously overwhelmed with all the things you tried to do, when each of them alone were already going to be a challenge.

    Overwhelm and breakdown are almost inevitable.

    And when they happen, chances are you will alienate people, and/or simply alienate yourself. You will hide away, you will avoid inflicting yourself on others, you will brood alone in frustration—or distract yourself with something mind-numbing.

    Before you know it, you’re too anxious to try to do things with other people or generally show your face to the world (because how will they react, and won’t you just mess things up anyway?), and/or too depressed to leave your depression-lair (because maybe if you keep playing Kingdom Vegetables 2, you can find a crumb of dopamine somewhere).

    What to do about it

    How to tackle the many-headed beast? By the heads! With your eyes open. Recognize and acknowledge each of the heads; you can’t beat those heads by sticking your own in the sand.

    Also, get help. Those words are often used to mean therapy, but in this case we mean, any help. Enlist your partner or close friend as your support in your mental health journey. Enlist a cleaner as your support in taking that one thing off your plate, if that’s an option and a relevant thing for you. Set low but meaningful goals for deciding what constitutes “good enough” for each life area. Decide in advance what you can safely half-ass, and what things in life truly require your whole ass.

    Here’s a good starting point for that kind of thing:

    When You Know What You “Should” Do (But Knowing Isn’t The Problem)

    And this is an excellent way to “get the ball rolling” if you’re already in a bit of a prison of your own making:

    Behavioral Activation Against Depression & Anxiety

  • The Truth About Statins – by Barbara H. Roberts, M.D.

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    All too often, doctors looking to dispense a “quick fix” will prescribe from their playbook of a dozen or so “this will get you out of my office” drugs. Most commonly, things that treat symptoms rather than the cause. Sometimes, this can be fine! For example, in some cases, painkillers and antidepressants can make a big improvement to people’s lives. What about statins, though?

    Prescribed to lower cholesterol, they broadly do exactly that. However…

    Dr. Roberts wants us to know that we could be missing the big picture of heart health, and making a potentially fatal mistake.

    This is not to say that the book argues that statins are necessarily terrible, or that they don’t have their place. Just, we need to understand what they will and won’t do, and make an informed choice.

    To which end, she does advise regards when statins can help the most, and when they may not help at all. She also covers the questions to ask if your doctor wants to prescribe them. And—all so frequently overlooked—the important differences between men’s and women’s heart health, and the implications these have for the efficacy (or not) of statins.

    With regard to the “alternatives to cholesterol-lowering drugs” promised in the subtitle… we won’t keep any secrets here:

    Dr. Roberts (uncontroversially) recommends the Mediterranean diet. She also provides two weeks’ worth of recipes for such, in the final part of the book.

    All in all, an important book to read if you or a loved one are taking, or thinking of taking, statins.

    Dr. Devi’s Spectrum of Hope

    This is Dr. Gayatri Devi. She’s a neurologist, board-certified in neurology, pain medicine, psychiatry, brain injury medicine, and behavioral neurology.

    She’s also a Clinical Professor of Neurology, and Director of Long Island Alzheimer’s Disease Center, Fellow of the American Academy of Neurology, and we could continue all day with her qualifications, awards and achievements but then we’d run out of space. Suffice it to say, she knows her stuff.

    Especially when it comes to the optimal treatment of stroke, cognitive loss, and pain.

    In her own words:

    ❝Helping folks live their best lives—by diagnosing and managing complex neurologic disorders—that’s my job. Few things are more fulfilling! For nearly thirty years, my focus has been on brain health, concussions, Alzheimer’s and other dementias, menopause related memory loss, and pain.❞

    ~ Dr. Gayatri Devi

    Alzheimer’s is more common than you might think

    According to Dr. Devi,

    ❝97% of patients with mild Alzheimer’s disease don’t even get diagnosed in their internist offices, and half of patients with moderate Alzheimer’s don’t get diagnosed.

    What that means is that the percentage of people that we think about when we think about Alzheimer’s—the people in the nursing home—that’s a very, very small fraction of the entirety of the people who have the condition❞

    ~ Dr. Gaytatri Devi

    As for what she would consider the real figures, she puts it nearer 1 in 10 adults aged 65 and older.

    Source: Neurologist dispels myths about Alzheimer’s disease

    Her most critical advice? Reallocate your worry.

    A lot of people understandably worry about a genetic predisposition to Alzheimer’s, especially if an older relative died that way.

    See also: Alzheimer’s, Genes, & You

    However, Dr. Devi points out that under 5% of Alzheimer’s cases are from genetics, and the majority of Alzheimer’s cases can be prevented be lifestyle interventions.

    Lastly, she wants us to skip the stigma

  • Shredded Wheat vs Organic Crunch – Which is Healthier?

    Our Verdict

    When comparing Shredded Wheat to Organic Crunch, we picked the Shredded Wheat.

    Why?

    In this battle of the cereals, it comes down to the ingredients:

    • The Shredded Wheat cereal has two ingredients: wheat (shredded), and BHT. The latter is a phenolic compound and antioxidant.
    • The Organic Crunch cereal has lots of ingredients, of which the first two are wheat flour, and sugar.

    This means that, per serving…

    • The Shredded Wheat cereal has 7g fiber and 0g sugar
    • The Organic Crunch cereal has 3g fiber and 12g sugar

    Quite a difference! Sometimes, the “Organic Crunch” of a product comes from crunchy sugar.

    You can check them out side-by-side here:

  • Watermelon vs Cucumber – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing watermelon to cucumber, we picked the cucumber.

    Why?

    Both are good! But in the battle of the “this is mostly water” salad items, cucumber wins out.

    In terms of macros they both are, as we say, mostly water. However, watermelon contains more sugar for the same amount of fiber, contributing to cucumber having the lower glycemic index.

    When it comes to vitamins, watermelon does a little better; watermelon has more of vitamins A, B1, B3, B6, C, and E, while cucumber has more of vitamins B2, B5, B9, K, and choline. So, a modest 6:5 win for watermelon.

    In the category of minerals, it’s a different story; watermelon has more selenium, while cucumber has more calcium, iron, magnesium, manganese, phosphorus, potassium, and zinc.

    Both contain an array of polyphenols; mostly different ones from each other.

    As ever, enjoy both. However, adding up the sections, we say cucumber enjoys a marginal win here.
