Depression: Symptoms, Treatment, and When to Get Urgent Help
Depression is a medical condition that can affect mood, thinking, sleep, appetite, energy, concentration, physical functioning and relationships. It is more than ordinary sadness, and effective treatment is available.
Common symptoms
Symptoms may include persistent sadness or emptiness, hopelessness, loss of interest or pleasure, irritability, guilt or worthlessness, fatigue, sleep changes, appetite or weight changes, difficulty concentrating, physical aches without a clear explanation, and thoughts of death or suicide. A person does not need every symptom to have depression.
When to seek help
Talk with a health professional when symptoms last around two weeks or longer, are severe, keep returning, or interfere with daily functioning. Other medical conditions and medications can sometimes contribute to depressive symptoms, so an appropriate assessment matters.
How depression is treated
Evidence-based treatment commonly includes psychotherapy, antidepressant medication, or both. The best approach depends on symptom severity, previous treatment response, preferences, medical history, pregnancy status, other medications and other mental-health conditions.
For some people with mild depression, psychotherapy may be tried first. Moderate or severe depression often requires medication as part of the initial plan. If standard treatments are not sufficient, specialist options such as brain-stimulation therapies may be considered.
Psychotherapy
Evidence-based psychotherapies include cognitive behavioral therapy (CBT) and interpersonal therapy (IPT). Therapy is not simply “thinking positively”; it is structured treatment delivered by a trained professional.
Antidepressants
Antidepressants can be effective, particularly for moderate or severe depression. They also have potential side effects and should be reviewed with a prescriber. Do not abruptly stop an antidepressant unless a clinician specifically tells you to do so, because discontinuation symptoms and symptom recurrence can occur.

What lifestyle measures can—and cannot—do
Regular physical activity, adequate sleep, social connection, structured routines and nutritious food can support mental health, but they are not substitutes for treatment when depression is moderate, severe, persistent or associated with suicidality. Chiropractic manipulation, supplements, “brainwave” products and spinal alignment are not established treatments for depression.
If there are thoughts of suicide or self-harm
Seek immediate help if you may act on suicidal thoughts or cannot stay safe. In Singapore, call 995 for an emergency, national mindline 1771, or Samaritans of Singapore at 1767. In the United States, call or text 988. Elsewhere, use your local emergency or crisis service.
