Feeling sad, discouraged, or emotionally drained from time to time is a normal part of life. However, when these feelings persist for weeks, interfere with daily functioning and affect your ability to enjoy life, they may be signs of depression, also known as major depressive disorder.
Depression is one of the most common mental health conditions worldwide and can affect people of any age, gender, or background. Fortunately, it is also highly treatable. Early recognition of the symptoms of depression and seeking appropriate support can make a significant difference in recovery.
As a licensed Naturopathic Doctor and primary care healthcare provider with nearly 20 years of clinical experience, I regularly work with patients experiencing depressive disorder, helping identify contributing factors, coordinating appropriate care and addressing the physical, emotional and lifestyle factors that influence mental health.
What is depression?
One of the questions I hear most often is, "What is depression?"
Depression is a medical condition that affects mood, thinking, behaviour, energy levels and physical health. It is much more than simply feeling depressed after a difficult day or stressful life event. Major depressive disorder involves persistent symptoms lasting at least two weeks that significantly interfere with work, relationships, school, or everyday activities. Depression affects how the brain regulates mood and emotions and is influenced by a complex interaction of biological, psychological, social and environmental factors.
Is depression a state of mind?
Many people wonder, "Is depression a state of mind?"
The answer is no.
Although depression affects thoughts and emotions, it is not simply a mindset or a lack of willpower. It is a recognized medical condition involving changes in brain chemistry, nervous system function, hormones, sleep regulation, inflammation, genetics and life experiences. While positive thinking and resilience can support recovery, depression cannot simply be "thought away." Professional assessment and an individualized treatment plan are often essential.
What causes depression?
Another common question is, "What causes depression?" There is rarely a single cause. Instead, depression usually develops from multiple interacting factors. Common contributors include:
- Genetic predisposition
- Chronic stress
- Traumatic life experiences
- Grief or loss
- Social isolation
- Hormonal changes
- Chronic illness
- Persistent pain
- Certain medications
- Sleep disorders
- Substance misuse
- Nutritional deficiencies
- Thyroid disorders
In many individuals, several of these factors occur simultaneously.
Risk factors for depressive disorder
Anyone can develop depressive disorder, but certain factors increase the likelihood.
Risk factors include:
- Family history of depression
- Previous episodes of depression
- Anxiety disorders
- Major life changes
- Chronic medical conditions
- Lack of social support
- Pregnancy and the postpartum period
- Menopause
- Financial stress
- Childhood adversity
Identifying these contributing factors helps guide appropriate treatment.
Common symptoms of depression include persistent sadness, loss of interest in activities, fatigue, sleep disturbances, changes in appetite, difficulty concentrating and feelings of hopelessness or worthlessness.
What are the symptoms of depression?
One of the most important questions is, "What are the symptoms of depression?" The symptoms of depression vary from person to person and may include emotional, physical and cognitive changes.
Common symptoms include:
- Persistent sadness
- Loss of interest or pleasure in activities
- Fatigue or low energy
- Changes in appetite
- Weight gain or weight loss
- Difficulty sleeping or excessive sleeping
- Difficulty concentrating
- Feelings of worthlessness
- Excessive guilt
- Hopelessness
- Irritability
- Restlessness
- Slowed thinking or movement
- Thoughts of death or suicide
Symptoms typically persist for weeks or months rather than improving after a few days.
Signs of depression
Sometimes family members recognize the signs of depression before the individual does.
Possible signs include:
- Withdrawing from friends and family
- Reduced motivation
- Poor work performance
- Neglecting self-care
- Reduced enjoyment of hobbies
- Increased tearfulness
- Low frustration tolerance
- Social isolation
Recognizing these early changes may allow for earlier intervention.
Feeling depressed versus clinical depression
Everyone experiences periods of feeling depressed, especially following disappointment, illness, or loss.
However, clinical depression differs because:
|
Feeling Depressed |
Major Depressive Disorder |
|---|---|
|
Usually temporary |
Persists for at least two weeks |
|
Triggered by a specific event |
May occur with or without an obvious cause |
|
Daily functioning remains largely intact |
Daily functioning is significantly impaired |
|
Mood gradually improves |
Symptoms often worsen without treatment |
Persistent symptoms deserve professional assessment.
Does depression cause mood swings?
Patients frequently ask, "Does depression cause mood swings?" It can.
Many individuals with depression experience fluctuations in mood, irritability, frustration, or emotional sensitivity throughout the day. However, dramatic or rapidly changing mood swings may also suggest other conditions such as bipolar disorder, hormonal changes, certain neurological conditions, or medication effects. A comprehensive assessment is important to establish the correct diagnosis.
Effects of depression
The effects of depression extend well beyond mood.
Depression may affect:
Physical health
- Fatigue
- Headaches
- Digestive problems
- Chronic pain
- Reduced immune function
- Poor sleep
Cognitive function
- Difficulty concentrating
- Memory problems
- Reduced decision-making ability
- Slower thinking
Emotional well-being
- Persistent sadness
- Anxiety
- Irritability
- Hopelessness
- Reduced confidence
Relationships and work
- Social withdrawal
- Relationship difficulties
- Reduced productivity
- Increased absenteeism
- Difficulty managing daily responsibilities
Depression affects the whole person, not just emotional health.
Severe depression
Severe depression may involve symptoms that significantly impair daily functioning.
Warning signs include:
- Inability to care for oneself
- Complete loss of motivation
- Significant weight loss
- Persistent inability to sleep
- Intense hopelessness
- Thoughts of self-harm or suicide
These symptoms require immediate medical assessment and should never be ignored.
The effects of depression extend beyond emotional health and can impact physical health, work performance, relationships and daily functioning, making early assessment and treatment especially important.
How is depression diagnosed?
Healthcare providers diagnose depression through a comprehensive evaluation that may include:
- Medical history
- Mental health history
- Review of symptoms
- Physical examination
- Screening questionnaires
- Blood work when appropriate to rule out contributing medical conditions such as thyroid disorders, anemia, nutritional deficiencies, or other health concerns
Because several medical conditions can mimic depression, identifying underlying physical contributors is an important part of a complete assessment.
The naturopathic approach to depression
Naturopathic Doctors are highly trained primary care healthcare professionals who are well-equipped to recognize depression, identify contributing medical conditions and collaborate with psychologists, psychiatrists, family physicians and other healthcare providers when appropriate.
Rather than focusing solely on symptoms, NDs evaluate the many factors that influence mental health, including sleep quality, nutrition, physical activity, digestive health, hormonal balance, thyroid function, chronic inflammation, stress, medications and lifestyle habits. This comprehensive approach helps uncover potential contributors while ensuring patients receive safe, evidence-informed care that complements conventional mental health treatment.
When should you seek immediate help?
If you or someone you know is experiencing thoughts of self-harm, suicide, or feels unable to stay safe, seek immediate medical assistance by calling emergency services or going to the nearest emergency department. You should also seek prompt assessment if symptoms of depression are significantly affecting your relationships, work, school, or ability to carry out daily activities. Depression is highly treatable and seeking help early often leads to better outcomes.

What is the cause of major depressive disorder?
Major depressive disorder does not usually have one single cause. It can develop from a mix of biological, genetic, psychological, medical and life-related factors. Brain chemistry, family history, trauma, chronic stress, certain medical conditions, substance use, grief, isolation and major life changes may all increase risk. Depression is not a personal weakness and it can affect daily mood, energy, sleep, appetite, focus and motivation.
What is it like having major depressive disorder?
Having major depressive disorder can feel like more than normal sadness. A person may feel empty, hopeless, tired, disconnected, guilty, or unable to enjoy things they once liked. It may also affect sleep, appetite, concentration, work, school, relationships and daily responsibilities. Some people may feel physically heavy or slowed down, while others may feel restless or irritable.
How to overcome major depressive disorder?
Major depressive disorder is usually managed with professional support, not simply willpower. Helpful steps may include speaking with a doctor or mental health professional, therapy, medication when appropriate, regular sleep, gentle physical activity, balanced nutrition, social support, stress management and avoiding alcohol or drug misuse. Recovery can take time and the right plan may be different for each person.
What is the most successful treatment for depression?
There is no single “best” treatment for everyone. The most effective treatment depends on symptom severity, health history, preferences and safety needs. Common evidence-based options include psychotherapy, antidepressant medication, or a combination of both. For moderate to severe depression, a combined approach may be recommended and severe or treatment-resistant cases may need specialized medical care.
How long does depression last?
Depression can last for different lengths of time. Major depression is generally diagnosed when symptoms last at least two weeks and interfere with daily life. Some episodes improve within weeks or months with support and treatment, while others may last longer or come back over time. Early care can help reduce the impact and support recovery.
Final thoughts
Depression is a common but serious medical condition that affects emotional, physical and cognitive health. Understanding what is depression, recognizing the symptoms of depression and identifying the signs of depression can lead to earlier diagnosis and more effective treatment. If you have been feeling depressed for more than a couple of weeks or notice that your mood is interfering with your daily life, don't hesitate to seek professional support.
As a primary care Naturopathic Doctor, I work with patients to investigate both the symptoms and the underlying contributors to depressive disorder, helping develop individualized care plans that support long-term mental and physical well-being while collaborating with other healthcare professionals whenever needed.
