The signs and effects of depression include feelings of hopelessness and sadness, listlessness, unexplained aches and pains, and more, as reported by HelpGuide.com. Depression differs from normal sadness in that it interferes with a person's day-to-day life. Symptoms can vary per individual.
Some other signs of depression include the loss of interest in daily activities, changes in appetite and weight, sleeping too much or too little, and anger or irritability, states HelpGuide.com. A depressed person may display excessive self-loathing, may engage in reckless behavior, such as gambling or drug use, and may not be able to concentrate even on simple tasks. Different people may have different symptoms and behaviors based on gender, age and circumstances.
In the worst case scenario, an individual with depression may attempt suicide. Some of the warning signs for a possible suicide attempt include an unusual preoccupation with death, calling or visiting people to say good-bye, and a sudden change from being angry or sad to being calm and happy, claims HelpGuide.com. In some cases, depression can be a sign of an underlying disorder, such as bipolar disorder. Determining the cause of the depression helps determine the course of treatment, which can include therapy, medication and alternative treatments.
