10 Important Causes of Exhaustion

In this article, we’ll cover the top ten reasons why you may be exhausted or fatigued.

I’ve experienced fatigue in the past, and I did not know the leading cause until now. I’ll share my experiences with you in this article.

What to do for exhaustion

The first thing you should do whenever you’re exhausted is to go back in your mind and try to recall when it started, and then look at what happened just before to get a clue. Was it diet? Was it stress-related? Was there some medication you got on, and you’ll know the exact cause? It’s simple but effective.

Now, let’s get on to what causes fatigue or exhaustion.

The most common causes of exhaustion or fatigue

Medication side effects

There are so many tired people around the world on medications. Unfortunately, they are not connecting the dots.

I’m not sure if there’s any medication that doesn’t give you side effects like lethargy, fatigue, or even lowered energy.

They all cause tiredness because they inhibit neurotransmitters.

This happens mostly when using antidepressants, anti-anxiety medications, or even high blood pressure medications. Those definitely will make you tired. So, you’re better off finding another solution.

I’m not advising that you come off your medication, but you can find another doctor and see if you can do something more natural. It doesn’t make sense to fix one problem and then trigger another one.

You may be running your body on the wrong fuel

It is important to note that burning fat fuel gives you a lot of energy. On the other hand, burning sugar fuel will make your roller coaster with your energy.

Consider starting a low-carb, healthy ketogenic diet. As always, discuss with your doctor before attempting.

Poor sleep

This is a huge one. If you are not sleeping as well as you should and are not feeling rejuvenated when you wake up, it could be your stress level; it could be something you’re deficient in.

So there are probably many reasons you may not sleep well enough. But it is important to note that if you are low in vitamin D or zinc, that alone will keep you from sleeping. And here’s a little tip. If you take vitamin D3 and zinc right before bed, you may sleep a lot better right off the bat.

An underlying or hidden infection

Getting rid of stress will help you. Stress activates cortisol. Cortisol paralyzes your immune system, that is, your white blood cells.

When you are heavily stressed, the cortisol will shut down your immune system, and the pathogens will come out and create many problems. So, you have to take care of your stress very well.

Post-Covid fatigue

A lot of people are complaining about post-covid fatigue. What you need at this time is a lot of vitamin B1. COVID-19 depletes your vitamin B1 stores. One of the significant side effects is a lack of energy because your mitochondria (your energy factories) need vitamin B1 to create energy, and you’re better off with the natural and not the synthetic version.

People with gastric bypass surgery are usually low in vitamin B1 and fatigued. Also, people who drink a lot of coffee and tea throughout the day are B1 deficient, which can cause fatigue and the need for more caffeine.

Keto fatigue

If you tried the ketogenic diet and you get keto fatigue, that’s mere that you’re missing either electrolytes, specifically potassium or B vitamins. The best supplement for B vitamins is nutritional yeast, unfortified.

Every cell in the body has this little pump called the sodium-potassium pump. These pumps generate energy for the nervous system and the muscular system. So it would be best if you had a lot of potassium to run that system. And if you add keto on top of it, the demand for these nutrients will go up.

Feeling very tired is one of the most common symptoms of iron deficiency anemia.

Unfortunately, this symptom is also common in people who don’t have enough iron, even if they haven’t received a deficiency diagnosis (12).

This fatigue happens because your body lacks the iron it needs to make a protein called hemoglobin, which helps carry oxygen around your body.

Without enough hemoglobin, less oxygen reaches your tissues and muscles, depriving them of energy. Your heart also has to work harder to move more oxygen-rich blood around your body, making you tired (1).

Since tiredness is often considered a part of a busy, modern life, it’s challenging to diagnose an iron deficiency based on this symptom alone.

Nonetheless, tiredness related to iron deficiency may go hand in hand with weakness, irritability, or difficulty concentrating (3).

Low thyroid

Low thyroid can make you tired. It could mean that you need a little bit of iodine or selenium, but most hypothyroid situations are autoimmune, where you have a lot of inflammation, and that could be causing the fatigue.

A natural remedy for Hashimoto’s thyroid problem and all other autoimmune diseases involves taking more vitamin D3. Take at least 30,000 IU per day. That is going to help reduce the inflammation and increase your energy. Talk to your doctor before consuming..


Mycoplasma is a stealth microbe that can hide in little calcium igloos called biofilms. Oregano oil works well against it.

Several measures can help lessen fatigue caused by daily activities. To help boost your energy levels and overall health:

  • drink enough fluids to stay hydrated
  • practice healthy eating habits
  • exercise regularly
  • get enough sleep
  • avoid known stressors
  • avoid work or social schedules that are overly demanding
  • take part in relaxing activities, such as yoga
  • abstain from alcohol, tobacco, and other illicit drugs

These lifestyle changes may help ease your fatigue. However, following your doctor’s recommended treatment plan for any diagnosed health condition is also essential.

If left untreated, fatigue can take a toll on your physical and emotional well-being.
