What Causes Headaches

 



Once in our lifetime we have had a headache, you know that

it can feel like your brain is trying to

push its way out of your head and while

that may make for a cool sci-fi movie it

throbs and it is generally a pretty bad

time so what the heck is going on here

Well, let's start off with a common

misconception: your brain is not actually

the thing that is hurting is, in fact, your

brain doesn't even have pain receptors

like the other parts of your body do

this is why it's possible for surgeons

to operate on a patient's brain while

they're still awake so if it's not the

brain that's hurting

What works well for most migraines? Blood.

Vessels seem to be the main culprit.

The theory is that serotonin and the other

Chemical messengers cause blood vessels

around the brain and head to swell this

increases blood flow and stretches

nearby nerve cells which send pain

signals to the brain and thus our heads

hurt along with vomiting and nausea, the

only Silver Lining is that migraines

only tend to affect one side of the head

Tension headaches, on the other hand

affect both sides and feel like a tight

band is squeezing the top of your head

as the name suggests these headaches are

the result of tension in the muscles of

your head and sometimes neck and if

you've ever gotten a headache after

wearing glasses with the wrong

prescription it's because the eye strain

triggered it lastly if you're going to

take painkillers to relieve the pain be

careful if you take them for too long

you may develop a medication overuse

headache Yes, you heard me right.

medication to treat headaches may cause

even more headaches kind of defeats the

purpose, doesn't it? Scientists aren't

exactly sure what causes them but it

seems to be connected to headache

specific pain Pathways and changes in

neuronal excitability.

  All kinds of digestive problems starting from the top of digestion all the way to the bottom and with elimination also people who are looking to have better metabolism and maybe work on their weight management So there are a couple of things that i notice one should overlook when it comes to improving their digestion and that is how they eat so Number one, we think of digestion as a processing of information, okay?

What causes heartburn?

Image
  Just between your chest and abdomen is where you’ll find one of the most important muscles you probably didn't know you had: the lower esophageal sphincter, or LES. When functioning properly, This ring of tissue plays a crucial role in helping us eat. But when the LES malfunctions, it becomes the main player in heartburn --a searing, sometimes sour-tasting chest-spasm that many people will experience at some point in their lives. We know that humans have been battling heartburn for hundreds, if not thousands, of years. But recently the incidence has risen, making it a common stomach complaint worldwide. When the symptoms of heartburn become more more regular and intense —such as twice a week or more-- It’s diagnosed as gastroesophageal reflux disease, or GERD. But what causes this problem? And how can it be stopped? Heartburn starts in an area called the gastroesophageal junction, where the LES resides. This smooth, muscular ring of the LES is moderated by an intricate tree of ne...
