Depression is a common but serious mental disorder that affects emotions, thoughts, and behaviors, and may even cause physical discomfort. It is not just a temporary low mood but a persistent mental illness that can impact daily life and social functioning. Below are the main symptoms of depression:

Detailed Symptoms of Depression

1. Persistent low mood

The most typical symptom of depression is long-term sadness, emptiness, or hopelessness, which cannot be relieved by positive external events. Patients may feel life is meaningless, and may also experience inferiority or helplessness.

2. Loss of interest or decreased pleasure

Individuals with depression often lose interest in previously enjoyable activities such as socializing, exercise, entertainment, or hobbies. They may feel that nothing brings joy, and even basic life needs become tedious.

3. Low energy and easy fatigue

Depressed patients often feel listless and easily fatigued, even without intense physical activity. Simple daily tasks such as getting out of bed or washing may become extremely difficult.

4. Sleep disorders

Sleep problems are common symptoms of depression, including insomnia or hypersomnia. Irregular sleep further aggravates mood problems, forming a vicious cycle.

5. Appetite and weight changes

Depression may cause a significant decrease in appetite, leading to weight loss; however, some patients may develop emotional eating, leading to weight gain. These changes are often related to individual coping mechanisms for stress.

6. Decline in concentration and cognitive ability

Patients may find it difficult to concentrate, have memory decline, struggle with decision-making, and appear slow in daily communication. They may feel mentally sluggish, with slowed thinking that impacts work and study efficiency.

7. Feelings of worthlessness or excessive guilt

Depressed patients often have strong negative thoughts, believing themselves to be useless or failures. They may repeatedly recall past mistakes and excessively blame themselves. Such negative thinking worsens depression and may lead to more serious psychological problems.

8. Self-harm or suicidal thoughts

In severe cases, patients may develop self-harming or suicidal thoughts and even take extreme actions. This is the most dangerous manifestation of depression and requires immediate professional help.

Conclusion

Experts at United Life International Medical Center emphasize that if you or someone around you shows the above symptoms, it is essential to seek psychological counseling or professional treatment in time. Depression cannot be resolved simply by “thinking positively.” It requires scientific interventions such as psychotherapy, medication, or lifestyle adjustments. Support from family and friends is also crucial in helping patients rebuild confidence and overcome difficulties.
