Hormones, Part 2: Cortisol, Adrenaline & Insulin

Now that we know about biochemicals and that hormones play an important role in keeping the biochemicals balanced, let’s learn more about these specific hormones.

Cortisol

Cortisol’s many functions include preventing blood sugar from falling too low, aiding the liver in energy storage and new sugar production for energy, mobilizing energy to the brain so we can think and act more efficiently, and fighting inflammation throughout the body. All good things! However, too much cortisol can lead to a serious imbalance within the body. Cortisol production can become out of balance as a result of STRESS: emotional stress, nutritional stress, chemical stress, physiological stress, or hormonal stress. When we have excess cortisol production, we use up our structural and functional biochemicals very quickly and become depleted. This leads to symptoms such as depression, memory loss, loss of lean body tissue, bone loss, type II diabetes, high cholesterol and triglycerides, redistribution of fat to midsection, high blood pressure, weakened immunity, and inflammation throughout the body.

Adrenaline

Adrenaline is also known as the “fight or flight” hormone, which I write about every now and then. It is secreted in large amounts when we are under any type of stress, and is secreted in smaller, more regularized amounts constantly to help the body do things like maintain heart beat, access biochemicals, break down food for energy, and break down old cells to rebuild new ones. High adrenaline levels can be addicting in the short-term, because they demand the use of all of our biochemicals which leads to a false sense of optimal health. This is why people may experience a “high” or energy burst when they are under tight deadlines or when they are in a dangerous situation and must act quickly and smartly. However, over time too much adrenaline production can lead to the body using up its storage of biochemicals faster than it can rebuild them. This leads to any of the following symptoms: agitation, anxiety, nervousness, bladder urgency, blurred vision, emotional intensity, excessive sweating, heart palpitations, inability to fall or stay asleep, loose bowels, headaches, mental exhaustion, and flulike symptoms.

Insulin

I write about insulin often in relation to blood sugar imbalances. Insulin is another very useful hormone, as it helps keep the body from using up too many biochemicals and is a major rebuilding hormone (assuming one is eating the proper nutrients). However, lifestyle-based insulin disorders are caused by the under- or over-secretion of insulin due to daily poor nutrition and/or lifestyle habits. These can include a diet too high in refined carbohydrates or processed foods; over-exercising OR not enough exercise; over-consumption of alcohol; smoking or drug use; and more. High levels of insulin lead to oxidation, which is the forming of free radicals inside the body. Eventually one will become insulin-resistant, which causes chronic high insulin levels. The following are symptoms of insulin-resistance: fatigue, brain fog, heart palpitations, difficulty sleeping, irritability, anxiety, loose bowels or constipation, panic attacks, severe sugar cravings, acne, depression, infertility and/or irregular menstrual cycles, and weight gain. If left untreated, insulin resistance will eventually lead to poor health and disease, including things like high cholesterol, high triglycerides, hypertension, type II diabetes, coronary and cerebral atherosclerosis, and even cancer.

Now that we know a little more about these three important hormones, we need to know how to rebalance them! On Friday, I will address this issue, including nutritional protocols for rebalancing the hormones.

Adrenal Fatigue: Part 2

Yesterday I talked about adrenal fatigue: what it is, what the symptoms are, and why it happens. Today, let’s look at some of the solutions.

The best way to approach this is to look at the stressors in our lives. Stress can include having a demanding job that soaks up too much of our time; feeling financially burdened because we have a family to support; emotional stress from our family life or personal issues; stress on our bodies due to poor diet or lack of adequate sleep; physical stress from training for races or other activities; and more. We all experience some level of stress. The difference is in how we approach this stress. I believe some level of stress is actually good – it helps motivation levels and keeps someone going. However, when we overreact to stress our body takes a toll, and we can start to show signs of adrenal fatigue.

Some stress is beyond our control, so let’s focus on the thing we can control: our diet. Diet is a great way to balance your adrenals and get your body in the best shape it can be to deal with the other stressors in life.

Since cortisol helps us to regulate our blood sugar, keeping blood sugar in balance will in turn keep cortisol levels more balanced. I’ve talked before about blood sugar and insulin resistance. Eating more protein at breakfast is the first step in balancing blood sugar. For someone whose blood sugar is out of whack, a fruit and yogurt parfait will just not cut it in the morning. Instead, they should be eating things like eggs, vegetables, nuts, and even a little meat or fish. In addition, mid-morning and mid-afternoon snacks are important. If someone with adrenal fatigue gets too hungry, more stress is put on the adrenals and they’ll experience increased symptoms. Snacks should be composed of whole foods and should include a fruit or vegetable as well as some protein and a little healthy fat. Examples: apples with almond butter; veggies with hummus; whole grain crackers topped with pesto; or berries and nuts with plain yogurt.

Since eating will give your cortisol levels a boost, it’s best to eat your biggest meal in the morning and a smaller meal in the evening. This will not only get you going in the morning, but will prevent unwanted energy bursts late at night that keep you from falling asleep when you get into bed. I often tell people not to be afraid to make breakfast their biggest meal of the day. It really sets the tone for your day and can be a powerful tool in weight loss, balancing hormones, increasing energy levels, and more.

Finally, someone who is experiencing some level of adrenal fatigue will find it very helpful to eliminate or reduce nutritional stressors such as caffeine, alcohol, refined or processed sugars and fats, and other processed foods. People with adrenal fatigue often have food sensitivities, especially to dairy or gluten, so eliminating these for a few weeks to see if there is a difference is often recommended. I know these things are difficult, so taking it slowly is a good idea. Focusing on whole foods, especially fresh fruits, vegetables, and lean protein, can really make a difference for people!

I know this is just a brief overview, but hopefully it gives you some idea of the direction you need to take and (more importantly) why you need to make the changes. I think it’s empowering to understand what is going on inside your body and make a conscious decision to make changes, rather than just follow a doctor’s or nutritionist’s orders without really understanding the “why”. The more people can educate themselves, the easier it will be for them to make decisions that are supportive of health and balance. I have seen the above nutritional recommendations make amazing changes for individuals, so I know that they work!

Have a great weekend!

Adrenal Fatigue

We talked briefly about adrenal fatigue in class this week. I’ve been learning bits and pieces about adrenal fatigue throughout the past year, and it’s something that, in my opinion, many people experience. I’m not going to go into a lot of detail here, but I want to give you an overview of what adrenal fatigue is and what some of the symptoms are. I believe that if you have it, you should know how to recognize it and how to go about dealing with it.

Adrenal fatigue occurs when we experience chronic stress. Under stress, our adrenals increase production of the hormone cortisol. When the hormone is released, certain receptors on our cells need to process the cortisol. However, when we have prolonged periods of stress, our receptors experience “burnout” and fail to respond to the cortisol. This leads to fatigue and exhaustion. Besides chronic stress, other items that can lead to adrenal fatigue include too much caffeine, sleep deprivation, severe trauma, some prescription medications, and prolonged physical exercise.

Some symptoms of adrenal fatigue include the following: difficulty waking up and becoming alert and energized in the morning; afternoon “crash” between 2:00 and 4:00 pm; energy burst in the early evening, and possibly again later at night (some people refer to this as their “second wind”); cravings for foods high in salts, sugar, or fats; sensitivity to cold or always feeling chilled; mild depression; mood swings; feeling rundown; lack of ability to deal with stress; prolonged sickness or inability to kick a cold or cough; decreased sex drive; increased food allergies or sensitivities. Obviously there are different degrees of adrenal fatigue, and if you are experiencing one or two of the above symptoms that does not necessarily mean you have adrenal fatigue. However, if you are experiencing a few of them, you may want to find out how you can better support your adrenals.

When left untreated, adrenal fatigue can lead to many different health problems. It is something that will drain your energy and weaken your bodily systems, to the point that they are not functioning properly and are more susceptible to disease.

Someone with health adrenals will have a daily energy curve that is something like this: medium energy in the morning that slowly rises to its peak level; a slight dip around lunchtime but then an increase right after lunch; a gradual decrease in early evening until bedtime. This person will wake up easily and fall asleep easily, because their body is balanced.

Someone with adrenal fatigue will have a daily energy curve that looks more like this: very low energy in the morning; huge energy spike after morning coffee and breakfast, but then huge dip right before lunch; slight spike after lunch but then another huge dip; gradual decrease until bedtime; possible spikes right before bed or while that person is trying to sleep. This person has a hard time getting going in the morning and tends to be more of a night owl or sleep more restlessly.
