What Is Depression?

Depression (Major Depressive Disorder) is a mood disorder characterized by persistent low mood, loss of interest, and reduced motivation. It must last at least two weeks or longer and interfere with daily living.

It affects:

  • Emotions

  • Thinking patterns

  • Sleep

  • Appetite

  • Physical energy

  • Work performance

  • Social interactions

Depression is treatable, and early detection improves outcomes dramatically.

 

 

Common Symptoms of Depression

Symptoms vary from person to person but often include:

Emotional Symptoms

 
  • Feeling persistently sad, empty, or hopeless

  • Reduced interest in activities

  • Irritability or emotional sensitivity

  • Feelings of guilt or worthlessness

Physical Symptoms

 
  • Fatigue or lack of energy

  • Sleep disturbances (difficulty sleeping or oversleeping)

  • Headaches, muscle pains, or digestive issues

  • Changes in appetite or weight

Cognitive Symptoms

 
  • Difficulty concentrating

  • Trouble making decisions

  • Slowed thinking

  • Memory lapses

If these symptoms last more than two weeks, it may indicate clinical depression rather than temporary stress.

Possible Causes of Depression

Depression rarely has a single cause. Instead, it results from a combination of biological, psychological, and environmental factors.

Biological Factors

 
  • Genetics

  • Hormonal imbalance

  • Vitamin deficiencies (e.g., B12, D)

  • Thyroid dysfunction

  • Chronic illness

  • Gut-brain axis imbalance

Psychological Factors

 
  • Past trauma

  • Long-term stress

  • Unresolved grief

  • Negative thinking patterns

  • Low self-esteem

Social and Environmental Factors

 
  • Workplace pressure

  • Relationship difficulties

  • Financial stress

  • Social isolation

  • Major life changes

Understanding the root cause is crucial in selecting the most effective treatment approach.

When to Seek Professional Support

You may consider speaking to a doctor or mental health specialist if you experience:

  • Symptoms persisting longer than two weeks

  • Emotional difficulties interfering with daily tasks

  • Sudden changes in sleep or appetite

  • Concentration problems affecting work or study

  • Persistent fatigue without a clear reason

  • Thoughts of self-harm or overwhelming distress

A professional assessment helps distinguish between depression, anxiety, burnout, hormonal imbalance, or other medical conditions that produce similar symptoms.

How Depression Is Diagnosed

The diagnostic process typically includes:

1. Medical Evaluation

A general practitioner (GP) may assess:

  • Overall health

  • Medication history

  • Sleep patterns

  • Lifestyle factors

Blood tests are sometimes recommended to identify medical causes such as thyroid disorders, anemia, or deficiencies.

2. Mental Health Assessment

This involves documenting symptoms, emotional patterns, and how the condition is affecting daily functioning. Screening tools can help determine the severity of depression.

3. Psychiatric Evaluation

A psychiatrist can confirm the diagnosis, rule out other mental health conditions, and provide guidance on treatment options tailored to each patient.

Evidence-Based Treatment Options for Depression

Treatment varies depending on the severity and underlying causes. Common approaches include:

1. Counselling or Psychotherapy

Therapy helps patients:

  • Understand their emotional triggers

  • Modify negative thought patterns

  • Develop coping strategies

  • Improve communication and self-awareness

This is one of the most effective long-term treatments.

2. Medication (When Appropriate)

Antidepressants may be recommended when symptoms are moderate to severe, or when therapy alone is insufficient. Medication is prescribed and monitored by a psychiatrist.

3. Lifestyle Interventions

These play a meaningful role in day-to-day improvement:

  • Regular exercise

  • Improved sleep habits

  • Balanced nutrition

  • Reducing alcohol

  • Increasing social connection

4. Addressing Physical Contributors

In some cases, treating underlying health issues such as thyroid imbalance, vitamin deficiency, or chronic illness leads to significant improvement in mood.

Types of Depression

Several forms of depression exist:

Major Depressive Disorder (MDD)

 

Marked by intense symptoms affecting daily life.

Persistent Depressive Disorder (Dysthymia)

 

Long-term low mood lasting at least two years.

Seasonal Affective Disorder (SAD)

 

Linked to changes in seasons or light exposure.

Postpartum Depression

 

Occurs after childbirth.

Situational Depression

 

Develops in response to difficult life events.

Each type may require a slightly different treatment approach.

Living With Depression

Recovery from depression is possible with the right support. Many people improve through a combination of therapy, lifestyle changes, self-care, and medical guidance. Progress may feel slow at times, but small steps eventually lead to meaningful change.

It is important to remember:

  • Depression is not your fault

  • You are not alone

  • Seeking help is a sign of strength

  • Treatment works for most patients
