This “Dangerous” Hormone Can Wipe Out Fatigue and Boost Your Energy

We live in a stressful world. Between work, the news, traffic, and all of life’s other pulls, we’re so over-extended it’s affecting our health. Unfortunately, we can’t do much about the world around us, but there’s hope.

Wouldn’t it be great if there was a way to help us respond to stress even better? What if it could wipe out our fatigue and boost our energy levels so we could handle all of that stress better?

Well, there is. Some people think this secret is a drug. But it’s not. It’s a very natural way to help your body become “stress resistant.” And most doctors are completely ignoring it. Here’s what you need to know.

You probably know that vitamin deficiencies can wreak havoc on your body. They can cause all sorts of problems that you wouldn’t normally attribute to deficiency. But vitamins are not the only deficiencies you need to consider. Mineral and hormone deficiencies are just as common. But most people don’t know what symptoms to look for.

This is also true for hormones. Many hormone deficiencies won’t show up on your lab test. That’s because the “normal” ranges for hormone levels only reflect the extremes found in the general population. Just because a lab value for a hormone falls in between these extremes does not mean that it represents an optimal value for the person being tested. So it’s vital you know what symptoms are common for certain hormone deficiencies.

I’ve told you in the past that thyroid hormone deficiencies will rarely show up on a lab test. But it’s not the only one. There’s another hormone deficiency that your local lab won’t tell you about. It’s hydrocortisone.

If you’ve ever had poison ivy or a very itchy rash, you may have used hydrocortisone cream to reduce the irritation. But there’s a lot more to hydrocortisone that you need to know.

Why You Need Hydrocortisone

Hydrocortisone is not a drug, it is a hormone. Your adrenal glands make hydrocortisone every minute of your life. You already have blood levels of this hormone. The problem is that you may not have enough. Many doctors and pharmacists mistakenly equate hydrocortisone with steroid drugs like prednisone. They also attribute the same list of side effects that are seen with these synthetic steroids to hydrocortisone. This is a poor comparison, because unlike these drugs, hydrocortisone is something your body needs to function well.

Since hydrocortisone is natural and your body makes it every day, the question then becomes, “Is your body making enough?” If it is, then there is no need to give it to you. But if your body cannot make enough, then the appropriate dose will dramatically improve your health.

You may have heard of hydrocortisone by a different name: cortisol. This is just a different term for the same hormone. And here’s what you need to know about this hormone.

Hydrocortisone is the master anti-stress hormone. Stress refers to any influence on the body that it has to adapt to. This includes mental stress, such as anxiety and depression. But it also refers to physical stresses like allergies, infections, pain, not enough sleep, drugs, excesses, etc. When the body faces stress, it must adapt in order to maintain balance (homeostasis). The key to maintaining this balance is the hormone hydrocortisone. As long as the body can manufacture enough hydrocortisone, it will continue to maintain balance in the face of stress.

In normal situations, the body makes about 20 mg of hydrocortisone per day. But in stressful situations, it needs much more – often in the order of 200+ mg per day. As long as the adrenal glands can keep on manufacturing the needed amount of hydrocortisone, the body will be able to deal with its stressors.

However, with persistent stress, for example a long-term illness, your adrenal glands will eventually become exhausted. When that happens, your adrenals will not be able to keep up with the body’s needs, and you have what Hans Selye, MD (the scientist who first described the long-term effects of stress) called adrenal exhaustion.

It is at this point that the stress becomes overwhelming, and the body loses its potential to heal. And the only way out of this trap is to supply the body with the hydrocortisone it needs while at the same time working on decreasing the stress.

“But wait a minute, Dr. Shallenberger, I’ve heard that excessive hydrocortisone can be dangerous.” That’s true, excessive hydrocortisone over a long period of time is dangerous. That’s why it’s important to get the dose right, and to stop the hydrocortisone when it’s no longer needed – i.e. the stress is resolved. Doctors trained in the physiological dosing of hydrocortisone know how to do that.

Here Are Several Things You Need to Know About Hydrocortisone

Hydrocortisone maintains a healthy mood in the face of stress – One of the surest ways to diagnose if a patient needs hydrocortisone is if their mood is changing. People with insufficient hydrocortisone levels often complain of a feeling of being easily overwhelmed. This can lead to depression, anxiety, frustration, and other emotional symptoms.

Hydrocortisone maintains a normal blood sugar and blood pressure – Hydrocortisone is the primary hormone that maintains healthy blood sugar and blood pressure levels. So two common signs of a deficiency are low blood pressure, which manifests as dizziness, and low blood sugar, which manifests as fatigue. The fatigue of hydrocortisone deficiency is one that is usually much worse in the afternoon than it is in the morning.

Hydrocortisone is instrumental in the breakdown and burning of fat – Without an adequate amount of hydrocortisone, the body will not be able to break down fat for energy production. This will lead to an over dependence on sugar metabolism, which leads to energy drops, and a marked craving for sugar and carbohydrates.

Hydrocortisone is instrumental in energy production – Without hydrocortisone, the body would not be able to produce the energy it needs to live, and it would quickly die. The organ most dependent on hydrocortisone is the brain. So when hydrocortisone levels are low, some of the first symptoms reflect decreased brain metabolism. This includes mental fatigue, along with a decreased ability to concentrate, remember, and focus.

Hydrocortisone is instrumental for thyroid metabolism – The thyroid hormones cannot function without enough hydrocortisone. So many times, when the patient has symptoms of low thyroid function, the real problem is a deficiency of hydrocortisone. Likewise, hydrocortisone cannot function without an adequate amount of the thyroid hormones. Because of this, most doctors usually give hydrocortisone with thyroid replacement.

Hydrocortisone is instrumental for immune system function – A deficiency of hydrocortisone is one of the major reasons why many people cannot stop getting repeated colds and flus. It is also the single most common cause of allergies.

Hydrocortisone protects against inflammation, allergies, fatigue, and autoimmune diseases. And lack of replacing the hormone is one of the reasons that people cannot get over these diseases.

Hydrocortisone is often needed on a continuous basis – In many cases, after a combination of using hydrocortisone for several months, along with eliminating the stresses that depleted the adrenal gland in the first place, the adrenal gland will be able to manufacture enough hydrocortisone by itself, and there will be no need to continue taking the hormone. However, it is also quite common for many people to need to take hydrocortisone for the rest of their lives in order to be optimally healthy. This lifetime need is something that is very common with all hormones.

Most doctors and pharmacists don’t know any of this – All of what you have just read here is unknown to most doctors and pharmacists. This is true for several reasons. First, they have never studied the physiological use of hydrocortisone. In school, they are only taught about the pharmaceutical use of synthetic cortisone steroids, and they don’t realize that hydrocortisone is different.

Second, they think that hydrocortisone is toxic in any dose. This is also because they keep thinking of hydrocortisone as a drug, and forget that it is a hormone that is naturally present in your body.

Third, they falsely believe that a deficiency of hydrocortisone is rare. They also believe the only time a deficiency occurs is when you have Addison’s disease. This is what they taught me in medical school. And like many of the things I learned there, it is wrong.

Hydrocortisone is safe – A deficiency of any hormone is dangerous, and an excess is also dangerous. This is also true of hydrocortisone. Getting the dose right is very important. Too little will not work. On the other hand, too much over too long a period of time is also bad. Fortunately, the doses that doctors use who are trained in the proper use of hydrocortisone are entirely safe.

So if you have any of the symptoms I’ve mentioned here, talk to your doctor about hydrocortisone therapy. Make sure you’re talking to a doctor who understands the proper use of this hormone. You can do this by asking if he’s ever prescribed it and what kind of success he’s seen. If he’s never prescribed it or seen any success, find another doctor. Many of the doctors at can help you.

And, finally, the best way to take hydrocortisone to fix a deficiency is in tablet form, not the over-the-counter cream. There’s nothing wrong with the cream, it just won’t fix a deficiency. There’s just not enough of it. So make sure your doctor gives you a prescription for the tablets.
