Stomach Acid
Since the entire mystery of heartburn causes rests with
stomach acid it is
best that we discuss it in additional detail as well. After all don’t forget, our plan is to learn as much as
possible about the condition so that we can regain control. This will also help us understand how our
physician came to the conclusion that we in fact do have acid reflux. For that we will have to skim over how
a normal digestive process works, and how that differs from what is going on in your
body.
Before we even swallow the first bite off our meal, the
sight and smell senses of our body engage and begin producing acid which is released into the stomach. As we start
chewing and breaking down our food, a mucus or saliva is also released into the mouth. Our saliva contains an
enzyme which helps break down the food and also lubricates the upper gastrointestinal tract. Our tongue is a large
muscle which moves the food around and finally pushes it down the back of our throat, a place also called the
pharynx.
This is where gravity gives a helping hand and along with the
muscular contractions inside of the esophagus moves the food downward. The food then passes through a narrow
opening of the esophagus also known as the lumen. The stomach
is made out of many different layers which work alongside each other in order to extract all of the carbohydrates,
vitamins, minerals, reabsorb electrolytes and other nutrients from the food and fluid which we provide it. This is
why it is so important to eat the right things, as otherwise your stomach is working very hard and not replenishing
the energy. As with a car if it doesn’t get the right fuel or enough fuel it will eventually start breaking
down.
The stomach
can change shape depending on whether it is full or empty and a normal digestive process takes between minutes and
several hours depending on the food. This is why we do not want to eat too much right before going to sleep as the
acid is released and can cause additional damage while we are laying down. The gravity is not working in our favor
and the stomach acid can easily find its way up the throat
and to the back of our mouth burning everything along the way. This is one of the reasons why some people call it
the silent acid reflux.
The most important part we need to understand is how the
stomach walls work and this will allow for us to see what the medication does. The parietal cell or the wall is the
origin of the stomach acid and it releases it based on one of three different triggers. The first one is
acetylcholine, which neurotransmitter triggered by the vagus nerve based on our sense of smell, look and taste. It
activates very small proton pumps to release the acid into our stomach. The second one is
histamines which are activated as the food
begins to stretch the stomach, and they also turn on the proton
pumps to start acid production. Our last trigger is gastrin, a hormone,
which moves through the blood stream and activates the proton
pumps.
If everything is working correctly the food in its liquid form
makes its way into the intestines. There are many reasons why things do not work as smoothly as they should but it
is great to at least understand the regular process. This will come handy when we talk about the different types of
medications, how they work and why they work.
