タイムライン

  • 00:00:00 - 00:05:00

    The video discusses the complexity of inflammation, noting that it's a natural immune response that serves to protect the body. While many health products claim to reduce inflammation, it is highlighted that inflammation is necessary for healing and survival. The five signs of inflammation—heat, redness, swelling, pain, and loss of function—are explained as integral to the body's healing process. Acute inflammation occurs quickly due to injury or infection, whereas chronic inflammation can last longer and cause health issues like heart disease and organ dysfunction. The video emphasizes that while inflammation can be harmful if prolonged, it is essential for recovery and body defense.

  • 00:00:00
    whenever i hear that a new health
  • 00:00:01
    product claims to reduce inflammation
  • 00:00:03
    some red flags go up in my brain it's
  • 00:00:06
    one of those words that's gotten more
  • 00:00:07
    popular in health marketing in the last
  • 00:00:09
    few decades and people are willing to
  • 00:00:10
    pay
  • 00:00:11
    real money to do something about it but
  • 00:00:13
    inflammation is a normal biological
  • 00:00:15
    process that our bodies use to keep us
  • 00:00:17
    safe
  • 00:00:17
    we don't want to get rid of all
  • 00:00:19
    inflammation so today
  • 00:00:20
    we're going to dig into the inflammatory
  • 00:00:22
    response and come away understanding why
  • 00:00:24
    those health claims need a little bit
  • 00:00:25
    more nuance attached to them
  • 00:00:28
    inflammation itself is an immune
  • 00:00:30
    response to some kind of problem in the
  • 00:00:32
    body
  • 00:00:33
    that response might be acute which means
  • 00:00:35
    it comes and goes quickly
  • 00:00:36
    or chronic it stays around longer it
  • 00:00:39
    could be triggered by
  • 00:00:40
    any kind of infectious or non-infectious
  • 00:00:42
    problem in the body
  • 00:00:43
    anything from bacteria in a dirty cut to
  • 00:00:45
    frostbite to a splinter
  • 00:00:47
    regardless of what initiates it though
  • 00:00:49
    the response is similar
  • 00:00:50
    from just living and being a human
  • 00:00:52
    you're probably familiar with the five
  • 00:00:53
    signs of inflammation firsthand
  • 00:00:55
    heat redness swelling pain and loss of
  • 00:00:58
    function
  • 00:00:59
    and they range from mildly annoying to
  • 00:01:02
    seriously debilitating but they actually
  • 00:01:04
    serve a specific role in protecting you
  • 00:01:06
    from further harm
  • 00:01:08
    and kicking off the healing process
  • 00:01:09
    contrary to what some may think
  • 00:01:11
    the increased heat is not there to try
  • 00:01:13
    to bake the infectious agent
  • 00:01:15
    it's there because the blood vessels
  • 00:01:17
    around the inflamed body part expanded
  • 00:01:19
    bringing more blood to that area
  • 00:01:21
    that's also why the area gets more red
  • 00:01:23
    you're passing more red blood cells
  • 00:01:24
    through the inflamed tissue
  • 00:01:26
    just like how your cheeks get warm and
  • 00:01:27
    red when you blush our blood is warm
  • 00:01:30
    and with more blood flow we feel more
  • 00:01:31
    heat along with more blood
  • 00:01:33
    the vessels that transport that blood
  • 00:01:35
    expand and become more permeable
  • 00:01:37
    which fills that area with fluid and
  • 00:01:39
    shows up externally as swelling
  • 00:01:42
    pain comes from the stimulation of pain
  • 00:01:43
    receptors from the initial injury
  • 00:01:45
    or from the inflammatory response itself
  • 00:01:48
    finally the loss of function could come
  • 00:01:49
    from either increased swelling which
  • 00:01:51
    reduces mobility
  • 00:01:52
    or from healthy tissue being replaced
  • 00:01:54
    with less flexible scar tissue over time
  • 00:01:57
    and that's only what we see from the
  • 00:01:59
    outside our immune systems orchestrate
  • 00:02:01
    all these different chemical messengers
  • 00:02:03
    called cytokines cyto for cell
  • 00:02:06
    kine for movement they're chemicals that
  • 00:02:08
    get cells to move to the inflamed
  • 00:02:10
    area you may have heard about cytokines
  • 00:02:12
    in the context of a cytokine storm
  • 00:02:14
    before
  • 00:02:15
    when these messenger molecules recruit
  • 00:02:17
    more immune cells which release more
  • 00:02:18
    cytokines which recruit more immune
  • 00:02:20
    cells and you get this feedback
  • 00:02:22
    loop that can cause sepsis or death and
  • 00:02:24
    during the normal acute inflammatory
  • 00:02:26
    response
  • 00:02:26
    they're recruiting mostly white blood
  • 00:02:28
    cells to the area to attack
  • 00:02:30
    any pathogens and all of this is a thing
  • 00:02:32
    so that your body can stomp out
  • 00:02:34
    whatever's trying to hurt it whether
  • 00:02:35
    it's a bacterial infection or a sprained
  • 00:02:37
    ankle
  • 00:02:38
    but sometimes this process takes a
  • 00:02:40
    little bit longer
  • 00:02:41
    our bodies continue to ship chemical
  • 00:02:43
    messengers and white blood cells to the
  • 00:02:44
    site
  • 00:02:45
    and if that creeps into the multiple
  • 00:02:46
    week long territory it's classified
  • 00:02:49
    as chronic inflammation you don't always
  • 00:02:51
    need an acute inflammatory response to
  • 00:02:53
    develop chronic inflammation though
  • 00:02:55
    like rheumatoid arthritis is an
  • 00:02:56
    autoimmune disease that causes
  • 00:02:58
    inflammation of the joints there was
  • 00:03:00
    never one big injury that kicked it off
  • 00:03:02
    either way chronic inflammation is where
  • 00:03:04
    this whole inflammatory response gets
  • 00:03:06
    more problematic
  • 00:03:07
    for instance patients with
  • 00:03:08
    atherosclerosis a narrowing of the
  • 00:03:10
    arteries around the heart that
  • 00:03:12
    predisposes folks to heart attacks
  • 00:03:13
    will have elevated cytokines and
  • 00:03:15
    inflammatory proteins in their blood
  • 00:03:17
    because of that
  • 00:03:18
    healthcare providers might look for
  • 00:03:19
    inflammatory markers in your blood as a
  • 00:03:21
    way of predicting your risk of heart
  • 00:03:23
    disease
  • 00:03:24
    if your liver experiences too much
  • 00:03:25
    inflammation you can permanently damage
  • 00:03:27
    the hepatocytes
  • 00:03:29
    cells that play a big role in metabolism
  • 00:03:31
    and immune function
  • 00:03:32
    your lungs are in the same camp one of
  • 00:03:34
    the reasons that cigarette smoking is so
  • 00:03:36
    lethal is because it causes a constant
  • 00:03:38
    inflammatory response in the lungs
  • 00:03:40
    that can narrow and stiffen the tiny
  • 00:03:42
    airways in your lungs making it harder
  • 00:03:43
    for air to pass through
  • 00:03:45
    so in the case of livers and lungs
  • 00:03:47
    chronic inflammation
  • 00:03:48
    literally leads to worse organ function
  • 00:03:50
    with that in mind
  • 00:03:51
    you can see why people would want to
  • 00:03:53
    reduce inflammation and certain drugs do
  • 00:03:55
    that but
  • 00:03:56
    through different mechanisms like if
  • 00:03:57
    you've gotten injured
  • 00:03:59
    you might have taken ibuprofen a
  • 00:04:01
    non-steroidal anti-inflammatory drug
  • 00:04:03
    or nsaid for the pain it works by
  • 00:04:06
    inhibiting certain enzymes in your
  • 00:04:07
    stomach that make compounds called
  • 00:04:09
    prostaglandins
  • 00:04:10
    those prostaglandins keep the
  • 00:04:11
    inflammation process going so
  • 00:04:13
    by inhibiting the enzyme that makes them
  • 00:04:16
    ibuprofen reduces inflammation
  • 00:04:18
    or people with rheumatoid arthritis
  • 00:04:20
    might take a drug that reduces
  • 00:04:21
    inflammation by inhibiting one of those
  • 00:04:23
    chemical messengers
  • 00:04:24
    called tumor necrosis factor alpha both
  • 00:04:27
    drugs result in a reduced inflammatory
  • 00:04:29
    response
  • 00:04:30
    but take different paths to get there
  • 00:04:32
    knowing all that we can't say that
  • 00:04:34
    inflammation is clearly bad or clearly
  • 00:04:36
    good
  • 00:04:36
    we need this process in order to survive
  • 00:04:39
    but too much for too long
  • 00:04:40
    can be harmful thanks for joining us for
