When Anxiety Isn't "Just Stress"
Many people think of anxiety as purely psychological.
They assume that if they feel anxious, nervous, overwhelmed, or emotionally reactive, the explanation must be stress, personality, life circumstances, or mental health alone. While these factors certainly matter, there is another piece of the puzzle that is often overlooked: hormones. Over nearly two decades of practice as a Naturopathic Doctor, I have seen countless patients who initially sought help for fatigue, menstrual irregularities, sleep concerns, or hormonal symptoms only to discover that anxiety was an important part of the picture. Conversely, many patients who present primarily with anxiety symptoms ultimately reveal patterns that strongly suggest a hormonal component.
The relationship between hormones and mood is complex, but it is also remarkably common. Understanding that connection can help explain why anxiety may worsen at certain times of the month, during perimenopause, after childbirth, or during periods of significant hormonal change.
Understanding the Anxiety Hormone Connection
The brain and endocrine system are constantly communicating. Hormones influence neurotransmitters, stress responses, sleep quality, energy production, inflammation & many other physiological processes that affect emotional well-being. This is why anxiety is rarely isolated to the brain alone. Hormonal fluctuations can alter how calm, resilient, focused, or emotionally stable a person feels from day to day.
When patients ask me about the role of the anxiety hormone, I explain that there is no single anxiety hormone. Rather, several hormones can influence anxiety symptoms either directly or indirectly.
These include:
- Cortisol
- Progesterone
- Estrogen
- Thyroid hormones
- Testosterone
- Insulin
Each of these hormones affects the nervous system in different ways.
Anxiety & the Menstrual Cycle
One of the clearest examples of hormone-related anxiety is the relationship between anxiety and menstrual cycle changes. Many women notice that their mood changes predictably throughout the month.
They may experience:
- Increased worry
- Feeling overwhelmed
- Irritability
- Emotional sensitivity
- Panic symptoms
- Sleep disruption
These changes often occur during specific phases of the menstrual cycle rather than randomly. For some women, anxiety symptoms are minimal for most of the month but become significantly worse during the week before menstruation. Others notice anxiety increasing around ovulation or during periods of hormonal transition. When anxiety follows a cyclical pattern, hormones deserve careful consideration
When patients ask, "Can low progesterone cause anxiety?" research suggests that progesterone influences receptors in the brain involved in mood regulation, which may help explain why declining progesterone levels are associated with increased anxiety symptoms in some women.
Can Low Progesterone Cause Anxiety?
One of the most common questions I hear is: Can low progesterone cause anxiety?
The answer is that low progesterone may contribute to anxiety symptoms in some individuals. Progesterone is often thought of as a reproductive hormone, but its effects extend far beyond fertility and menstrual cycles. Progesterone interacts with receptors in the brain that influence mood, emotional regulation & the nervous system. When progesterone levels are adequate, many women report feeling calmer, more resilient & emotionally balanced.
When progesterone declines, some women notice:
- Increased anxiety
- Heightened stress sensitivity
- Poor sleep
- Restlessness
- Mood instability
This does not mean low progesterone is the sole cause of anxiety, but it may be an important contributing factor.
This is particularly relevant during:
- The late luteal phase of the menstrual cycle
- Perimenopause
- Menopause transition
- Certain hormonal conditions
Cortisol: The Classic Anxiety Hormone
If one hormone is most commonly associated with anxiety, it is cortisol. Cortisol is produced by the adrenal glands and plays a central role in the body's stress response. When faced with a challenge or threat, cortisol helps mobilize energy and increase alertness. This response is essential for survival. The challenge arises when stress becomes chronic.
Persistent elevations or dysregulation of cortisol can contribute to symptoms such as:
- Anxiety
- Difficulty relaxing
- Sleep disruption
- Racing thoughts
- Increased vigilance
- Feeling "wired but tired"
This is why chronic stress and anxiety frequently occur together.
Estrogen & Mood
Estrogen is another hormone that significantly influences emotional well-being. Its effects on neurotransmitters such as serotonin and dopamine help explain why fluctuations in estrogen can affect mood.
Many women notice emotional changes during times when estrogen levels are shifting, including:
- Puberty
- Pregnancy
- Postpartum
- Perimenopause
- Menopause
Rapid changes in hormone levels may be more impactful than the absolute hormone level itself. This helps explain why hormonal transitions are often accompanied by increased anxiety symptoms.
Thyroid Hormones & Anxiety
The thyroid gland also plays an important role in mood regulation. When thyroid hormones become imbalanced, symptoms can sometimes mimic anxiety disorders.
Individuals with thyroid dysfunction may experience:
- Nervousness
- Restlessness
- Heart palpitations
- Difficulty concentrating
- Sleep disturbances
Because of this overlap, evaluating thyroid health is often an important part of understanding persistent anxiety symptoms.
Why Hormonal Anxiety Is Often Missed
One reason hormone-related anxiety is frequently overlooked is that symptoms can appear psychological even when biological factors are contributing.
Patients may be told:
- "It's just stress."
- "You're worrying too much."
- "This is normal."
While emotional and psychological factors are important, it is equally important to recognize that physiology matters. Hormones influence how the brain functions, how stress is perceived & how the nervous system responds to everyday challenges. Ignoring this connection may leave important pieces of the puzzle unexplored.
There is no single anxiety hormone, but hormones such as cortisol, estrogen, progesterone, thyroid hormones & insulin can all influence the nervous system, stress response & emotional well-being, highlighting the important relationship between hormones and mental health.
Why Naturopathic Doctors Are Well Suited to Assess Hormonal Anxiety
Naturopathic Doctors receive extensive training in:
- Hormonal health
- Mental health care
- Stress physiology
- Nutrition
- Lifestyle medicine
- Natural medicine
- Primary healthcare assessment
Because anxiety can arise from multiple overlapping causes, NDs are trained to evaluate both the physical and emotional factors that may be contributing. In clinical practice, this means looking beyond symptoms alone and considering how hormones, stress physiology, sleep, nutrition & overall health may be influencing mental well-being. This comprehensive perspective is one reason many patients seek naturopathic care when anxiety and hormonal concerns appear interconnected.
Persistent anxiety, mood swings, sleep problems & panic symptoms may be signs of an underlying hormonal imbalance not just stress. Identifying the root cause is the first step toward lasting relief.

What hormones cause panic attacks?
Fluctuations in cortisol, estrogen, progesterone & thyroid hormones can contribute to panic attacks and anxiety symptoms. Imbalances in these hormones may affect the body's stress response and nervous system regulation.
Can an increase in estrogen cause anxiety?
Yes, rapid changes or elevated estrogen levels can influence brain chemicals like serotonin and may contribute to anxiety, mood swings & emotional sensitivity in some individuals.
What hormone is triggered by anxiety?
Anxiety activates the release of cortisol, often called the stress hormone. Adrenaline is also released, causing symptoms such as a racing heart, rapid breathing & heightened alertness.
How to stop hormonal anxiety?
Managing hormonal anxiety often involves improving sleep, reducing stress, balancing blood sugar, exercising regularly & addressing underlying hormone imbalances with personalized care and nutrition.
