What Are The Symptoms Of Depression And How To Prevent Them?

LanternVector Updated: 2025-08-08

Symptoms

Depressive episodes include sadness and/or hopelessness, fatigue, weight gain or loss, changes in sleep patterns, feelings of worthlessness, or suicidal thoughts. Depression can last for weeks or months and affect work, social life, and family relationships.
Sometimes it takes friends or family to recognize the warning signs of a possible depressive episode. They can tell you when you're feeling bad and suggest you see a doctor for further evaluation.

causes

Depression can be caused by a variety of factors, such as genetics, brain chemistry, and stressful life events. It is more common in women than men.
Depressive episodes are characterized by overwhelming sadness and loss of interest in activities that you once enjoyed. They usually last at least two weeks and affect your ability to work or care for yourself.

Treatment

Treatment for depression does not always result in a complete disappearance of symptoms, but it can help you live a more normal life and prevent depression from returning in the future.
Your doctor may prescribe antidepressants, which improve the function of neurotransmitters in your brain that control mood. They may be combined with other treatments, such as psychotherapy.
Cognitive behavioral therapy (CBT) teaches you how to change negative thoughts and behaviors that contribute to depression. It can be effective for moderate to severe cases of the disorder, but should always be used in combination with an antidepressant for the most benefit.

prevention

Depression is a chronic illness that can affect your mood, behavior, and health. Although it is not always easy to diagnose and treat, effective treatment can reduce symptoms and prevent them from recurring.
Major depressive disorder can recur, but people who have had a depressive episode before can prevent future episodes by sticking to their treatment plan and paying attention to potential triggers. Recent research suggests that maintaining a sleep schedule and avoiding unhealthy foods can also reduce the likelihood of relapse.
