Struggling with stubborn weight gain or an inability to lose weight? Have you tried fad diet after fad diet, and the scale still won’t budge? I’m here to tell you that it may not be your diet alone that’s preventing you from losing weight… at least not entirely.
We tend to look at weight loss as black and white: calories in versus calories out. However, we’ve come to understand that it is not that simple. There can be many things contributing to weight gain, including your hormones.
When was the last time your doctor checked your bloodwork? Weight gain has so many hidden causes, and it is important to assess the aetiology of your symptoms so you can make the best diet and lifestyle decisions uniquely for you.
Comprehensive Testing for Stubborn Weight Gain
To get to the root of your weight loss struggles, you and your physician should consider comprehensive testing. Important markers include:
- Complete Blood Count (CBC) and Complete Metabolic Panel (CMP)
- Fasting Insulin and HbA1c
- Thyroid Stimulating Hormone (TSH), Free T4, Free T3, and Reverse T3
- Cholesterol and hsCRP (inflammation markers)
- AM Cortisol and DHEA-S
- Vitamin D, Vitamin B12, Folate, Vitamin C, and Ferritin
- Estradiol, Estrone, Progesterone, and Testosterone
Other specialty testing, including a Comprehensive Stool Analysis, Salivary Cortisol Test, and Food Sensitivity Test may also be indicated. Of the many causes of stubborn weight gain, Adrenal fatigue or adrenal insufficiency is a primary suspect.
What Are Your Adrenal Glands?
To understand adrenal fatigue, we first need to look at the Endocrine system. Your adrenal glands are a pair of two glands located right above each kidney. They produce several hormones responsible for essential bodily functions, including regulating your immune system, stress response, metabolism, and blood pressure.
The adrenal glands have two main parts, each responsible for producing different hormones:
1. The Adrenal Cortex
The adrenal cortex makes up most of your adrenal gland and is the outermost part. It is made up of three zones:
- Zona Glomerulosa: Secretes aldosterone, a steroid responsible for regulating the salt and water in your body (which affects blood pressure).
- Zona Fasciculata: Secretes cortisol.
- Zona Reticularis: Secretes androgens (like DHEA and androstenedione) and a small amount of glucocorticoids. DHEA is a precursor to other hormones, like testosterone and estrogen.
2. The Adrenal Medulla
The innermost part of the adrenal gland secretes primarily Adrenaline (epinephrine) and norepinephrine. These are your stress hormones and neurotransmitters that are released when you are in a “fight or flight” state. These chemicals cause your blood pressure and heart rate to increase and your blood sugar to spike.
What is Cortisol?
Cortisol is a glucocorticoid hormone produced and secreted by your adrenal glands. Known as your primary stress hormone, your cortisol plays a large role in regulating your blood sugar, blood pressure, circadian rhythm, energy, metabolism, and inflammation.
What Are Ideal Cortisol Levels?
In normal adrenal function, cortisol should be highest in the morning and reduce as the day progresses. Morning cortisol levels should be between 6.2−19.4 μg/dL. If your cortisol is below that or at the absolute bottom range of “normal,” it indicates you have a low cortisol awakening response.
Causes for low cortisol can include physiological burnout, chronic fatigue, poor sleep, or chronic pain—all of which contribute to adrenal fatigue.
Identifying Adrenal Fatigue
Adrenal fatigue is a condition whereby your adrenal glands have endured a lot of stress and have been overworked, causing them to eventually produce less cortisol. When this happens, you experience symptoms associated with low or suboptimal cortisol, including:
- Severe fatigue and sluggishness
- Insomnia or trouble falling asleep
- Stubborn weight gain
- Brain fog
Ruling out Addison’s Disease
Your physician should also assess you for a more serious medical condition known as Addison’s disease, as the medical treatment will vary significantly. Signs of Addison’s Disease include:
- Extreme salt cravings
- Unexplained weight loss
- Muscle weakness and fatigue
- Loss of appetite
- Skin discoloration or hyperpigmentation
- Lightheadedness and dizziness
How to Lose Weight with Adrenal Fatigue
If you are struggling to lose weight and suspect your hormones are to blame, addressing the root cause of your adrenal stress is the first step. By working with an integrative health specialist to regulate your cortisol output, balance your endocrine system, and reduce chronic inflammation, your body can finally exit “survival mode” and begin releasing stubborn weight safely and naturally.
