It is common knowledge that people suffering from depression often end up with addiction and substance use disorder problems. This is because these individuals often take these drugs to help them manage their depressive symptoms. However, when taken long enough, this can result in depression.
This article explores the relationship between addiction and depression, looking at how and what causes these conditions to co-occur in patients.
Addiction and depression are both challenging conditions and can be somewhat complex to manage.

Depression is a common condition among people battling alcohol and drug addiction. It is a disorder that causes a continuous feeling of emptiness and sadness. It is not the same as the regular mood swings people experience; thus, it shouldn't be confused for those "transient" negative emotions people feel in response to difficult situations.
Depression can last for weeks, months, and sometimes years despite a change in circumstances and results in more intense and persistent feelings that tamper significantly with a person's life, including their ability to maintain a healthy lifestyle and work.

Diagnosis of depression and addiction usually follows a somewhat "stepwise" pattern, starting with a physical examination.
It is important to recognize the symptoms of depression in order to recognize a potential condition, but to then present the issue to a medical professional.
Your doctor will conduct a physical examination to check whether any underlying medical issues might be connected to any depressive symptoms you might be experiencing.
Blood tests can rule out numerous underlying medical disorders that can cause depressive symptoms. For instance, a thyroid test or complete blood count will ensure that various body hormones are balanced and are operating correctly.

Depression and substance abuse are related in the sense that one must happen for the other one to happen, although sometimes they might occur simultaneously. Research has shown that there is a relationship between depression and substance abuse.
Most people with depression also have addictions because these two disorders are connected and co-occur, creating a cycle. To self-medicate depression symptoms, patients use drugs excessively; however, this often leads to dependence on these drugs and, thereafter, addiction.
