This Is What Happens When You Drink a Coffee on an Empty Stomach

October 2, 2019

You might think drinking coffee in the morning
is a great idea. You may even think it’s a great way to get yourself going in the morning. But you’d be surprised to learn that drinking
coffee first thing in the morning- especially on an empty stomach- is a terrible idea. Why? Let’s take a look at a few reasons. 1. Stomach Acid Your stomach has hydrochloric acid, which,
at the right level, helps your body digest food properly. When your stomach is empty,
this acid doesn’t have much to work with, so it can slosh around and hurt your stomach. Drinking a cup of coffee on that empty stomach
adds to the problem by putting more acid in your body. Always having too much stomach acid will harm
your stomach and digestive tract, leading to problems like heartburn, irritable bowel
syndrome, and stomach ulcers. 2. Bad Digestion Having caffeine on an empty stomach ruins
digestion, leading to a bloated feeling and other signs of irritable bowel syndrome, like
pain and irregularity. How? Caffeine acts like your adrenal glands, which
create stress hormones called cortisol and adrenaline. When these hormones flood your body, they
raise your heart rate and blood pressure, and your liver starts letting out blood sugar
to give energy to muscles so that you can run away. Your digestive system also shuts down to send
energy to where it is needed most. 3. Anxiety When you go through your morning on an empty
stomach, you lower your brain’s power to properly break down serotonin. Serotonin is the “happy, calm hormone”.
When your brain is unable to break down this hormone properly, it causes anxiety and depression. Throwing a cup of coffee on top of that empty
stomach causes anxiety by boosting your body’s cortisol and adrenaline levels. That will leave you feeling shaky, nervous,
and weak. 4. Dehydration Drinking coffee on empty stomach raises the
amount of fluid that your body passes, and can cause dehydration. If you’re like most people, you’ll likely
answer to that dehydration by reaching for yet another cup of coffee, making things even
worse for yourself. 5. Low Levels of Serotonin Very few people know about this, but coffee
will make you feel less hungry. People who drink coffee right away in the
morning sometimes end up skipping breakfast. Skipping your first meal of the day can ruin
your body’s power to make serotonin, a neurotransmitter in charge of making you feel happy and calm. Also, serotonin is very important for a good
night’s sleep. Your body changes serotonin into melatonin
at night. Low levels of melatonin usually lead to insomnia
problems. If you like drinking coffee, make sure to
always have it after breakfast. If you like the video, give it a thumbs up

    Ok so question. I drink 24-32 oz of water first thing when i wake up. I practice intermittent fasting so all i consume is the water first then I drink my black coffee. 12-20 oz depending on cold brew or what not. Do these same aspects apply even though i drank water first?

    I am a medical doctor, and I gotta say that whenever I drink coffee very early in the morning, and specially when I haven't eaten anything, my gastritis worsens, and I also get loose stools (irregularity in my stools). Every time I watch videos like this I always doubt myself to totally believe everything they say because i don't know their source of information. There are not a lot of actual scientific studies out there to prove that coffee is as harmful as this video states. I still love coffee though, don't get me wrong. I wish it didn't mess with my peristalsis.

    NEVER do this. I almost died from drinking 440z of coffee, sugar and creamer. It only took an hour till I got a severe headache, uncontrollable shaking, sweating, and rapid heartbeat.

    Sadly, it was at the time I didn't have PE at school so I was basically sitting in class. It took me 3 hours for my body to calm down but for a month, I had to take pain relievers for my chest pains. In addition, the mental trauma of the whole event basically ruined my likeness for coffee only.

    As far as I am aware Hydrochloric acid doesn't just sit sloshing around in the stomach. If it did it would burn a hole! Hydrochloric Acid is produced IN RESPONSE to food or drink entering the stomach.

  • Reply Nikolaos Peterson October 4, 2018 at 11:10 pm

    Coffee I think empties my stomach. I am one of those who should not partake in coffee, as it is the number one cause of severe diarrhoea with me. (No it is not bloody, but looks like milk coffee in the toilet (or my clothing, or floor , or shower, or bed! It is the most stimulant for me and ALWAYS gives me that urgent calling that can and does occasionally turn out rather embarrassing! Chocolate is another culprit to me but fortunately not as severe. I am from Switzerland (we make the BEST chocolate on the planet!) Belgium is number two. We as Swiss are VERY impartial to our chocolate. Thus to me it is worth the little diarrhoea attacks I get as side effects. I would not be caught dead without my Swiss chocolate — diarrhoea or no diarrhoea! So those are basically the two foodstuffs that turn my organic plumbing system into a 'Shinkansen' (high-speed train).

    Cant speak for everyone, but the other day i had two cups at a friends house on an empty stomach and had my first meal until lunch time. hour or so later I literally thought i was going to have a heart attack, got terrible anxiety, palpitations and numb face and feeling. I usually have low blood pressure and anxiety problems so i do not know if there is a correlation. either way for some it might be fine but for others always try to eat something first before you drink two cups of coffee straight.
