What Are the Primary Causes of Depression?
Here’s a breakdown of the causes mentioned and some additional information to help you understand them better:
1. Abuse
According to 2021 research, abuse (especially psychological abuse) is a significant factor in the development of depression. It emphasizes that abuse, especially in childhood, increases the risk of developing various mental and physical health problems, including depression.
Thus, experiencing sexual, physical, or psychological abuse can increase the risk of developing depression later in life. The trauma and emotional toll of abuse can have long-lasting effects on mental health.
2. Aging
As individuals grow older so they tend to face many challenges that may lead to depression. Aging can bring about physical health issues, loss of loved ones and significant lifestyle changes, all of which can contribute to feelings of sadness and hopelessness.
Studies show that more than two million people over 65 in the US experience this mental health challenge. This high number highlights how common depression is among older adults. Factors like chronic illness, reduced mobility, and social isolation can all play a role in this increased risk.
3. Certain Medications
Individuals who take drugs to minimize the pains they are going through eventually become addicted to them. Thus when not available it leads to severe stress that causes depression.
Moreover, people who take steroids for a long time can sometimes make a person feel down and unhappy which contributes to depression.
Additionally, research shows that some drugs can cause depression as a side effect, a condition known as “organic mood syndrome.” Taking specific medications like corticosteroids, interferon-alpha (an antiviral medication), or isotretinoin (used for acne treatment) can promote the risk of depression. It’s important to be aware of the potential side effects of these medications and discuss any concerns with a healthcare professional.
4. Conflict
A study published in 2023 found that depression symptoms are strongly correlated with unhealthy interpersonal relationships. Individuals who are already prone to feeling sad and hopeless get into big fights and arguments with their loved ones frequently. It eventually makes them feel that nobody can understand them and thus gets lonely which is a root cause of depression.
So people with a biological tendency to depression may be more prone to experiencing depressive symptoms when facing interpersonal problems or disagreements with friends and family members. Stressful relationships and unresolved disagreements can contribute to the development or worsening of depression.
5. Loss or Demise of a Loved one
Research suggests that the loss of a loved one is a significant life event that can trigger depression in many people. Individuals who lose someone they love and have a strong bond with them like a family member or close friend, can make them feel incredibly sad for a long time.
Grief and sadness are natural responses to the loss of a loved one. However, the risk of depression may increase during this period. The emotional impact of losing someone close can be overwhelming and may trigger or worsen depressive symptoms. While grief is a normal and expected reaction to loss, prolonged or severe grief can develop into depression.
6. Hormonal Changes
Hormonal changes can play a significant role in causing depression. Hormones are chemicals in our bodies that regulate many functions, including mood. When there are imbalances or fluctuations in these hormones, it can lead to feelings of sadness or depression.
Research indicates that women are more prone to depression because of hormonal changes, especially during times of significant hormonal fluctuations like the menstrual cycle, pregnancy, and postpartum period, as well as menopause. The sudden drop in hormones after childbirth, known as postpartum depression, can be particularly severe.
Similarly, thyroid problems can also cause depression. The thyroid gland produces hormones that control metabolism, and when itās underactive (a condition known as hypothyroidism), it can lead to fatigue and depression.
In men, low levels of testosterone can also contribute to depression. This is especially common as men age, and their hormone levels naturally decline.
7. Genes
Depression often appears in families, suggesting a genetic link. While having a family member with depression doesn’t guarantee you’ll experience it, it does increase your risk. Research suggests a higher risk of depression among relatives of those with the condition. It’s likely that multiple genes work together, rather than a single “depression gene,” to influence a person’s vulnerability to this mental health condition.
If many people in a person’s family have had depression before, they might have a chance of experiencing it too because it could be something that runs in their family. Understanding the genetic basis of depression is complex, and it differs from more straightforward hereditary diseases.
8. Life Events
Major life events, such as starting a new job, graduating, getting married, or experiencing significant changes like moving, job loss, divorce, or retirement, can contribute to depression. While it’s common to feel a temporary sense of sadness or stress in response to these events, clinical depression involves more severe and persistent symptoms.
Other personal challenges, such as social isolation resulting from other mental health conditions or being rejected by family or social groups, can contribute to the development of depression. Feelings of loneliness and lack of social support can hurt mental well-being.
9. Nutritional Deficiencies
A 2023 research suggests a strong link between nutrient deficiencies and the development of depression. While diet alone isn’t the sole factor, specific nutrient shortages, such as those in B vitamins, vitamin D, omega-3 fatty acids, and minerals like magnesium and zinc, can impact brain function and mood regulation. Both the neurological system and the blood vessels are thought to be affected by it.
In terms of mood regulation, B12/B9, or folate, is on the top of the list. People who are depressed typically have reduced blood levels of folate (B12/B9). Omega-3 fatty acids are essential for maintaining mental acuity and a cheerful disposition. Thus its deficiency can cause depression.
Moreover, the lack of probiotics, beneficial bacteria and yeast in the gut, affects billions globally and can lead to serious symptoms, including depression. Probiotics aid digestion, manage stress, enhance mood, and support mental wellness, so their deficiency can contribute to depression, while balanced probiotics reduce this risk.
10. Severe Ailments
Depression may result from a chronic disease in certain individuals. According to research, having a physical illness increases the likelihood of developing depression. The stress and challenges of managing a physical illness can trigger depressive symptoms.
A chronic ailment lasts for an extended period and typically cannot be fully healed. The burden of dealing with a significant health condition can take an emotional toll and contribute to the development of depressive symptoms. Additionally, certain medical conditions themselves can directly cause depression. Diabetes, heart disease, arthritis, renal disease, HIV and AIDS, lupus, and multiple sclerosis (MS) are a few examples of chronic conditions that can lead to depression.
11. Substance Abuse
Research indicates that drug abuse can indeed contribute to depressive disorder. Depression and other mood disorders are commonly found in people with substance abuse problems.
Substance abuse and depression are closely linked. According to PubMed, around 30% of people with substance abuse issues also have significant or clinical depression. While drugs and alcohol may temporarily alleviate negative emotions, they ultimately worsen depression and can lead to a vicious cycle of dependency and worsening mental health.

2. Does a lack of exercise play a role in depression?
Exercise has been indicated to have a favorable influence on mental health. Lack of exercise may contribute to feelings of low mood or depression. Engaging in regular physical activity, even in small amounts, can have mood-lifting effects.
3. Can trauma cause depression?
Yes, experiencing trauma, like a bad event or a difficult situation, can sometimes lead to depression. Trauma can affect our thoughts and feelings, making us more likely to feel sad or down.
4. Can social media use lead to depression?

5. Does stress cause depression?
Yes, stress is among the major causes of depression. When we have too much stress for a long time, it can affect our mood and make us feel overwhelmed, sad, or hopeless.
6. What are the Biological Causes of Depression?
Research shows that individuals with depression often have noticeable changes in their brains compared to those without depressive symptoms. One key difference is that people with depression may have a smaller hippocampus, a brain region essential for memory storage. This smaller hippocampus has fewer serotonin receptors, which are crucial for emotional processing.
The exact reason for a smaller hippocampus in depressed individuals is unknown. However, studies suggest that prolonged sadness and elevated levels of the stress hormone cortisol can have a harmful effect, shrinking the hippocampus over time.
7. Can a lack of sunlight cause depression?
One of the many causes of depression is the lack of sunlight. Yes, sunlight helps our body produce vitamin D, which can affect our mood. Lack of sunlight, especially during darker months, may contribute to a type of depression called seasonal affective disorder (SAD).
8. Are Depression and Grief the Same?
Grief is a typical, acceptable reaction to loss. Losses that can cause sadness include losing a loved one, losing a job, losing a cherished pet, or going through any number of other life transitions like divorce, being an “empty nester,” or retiring.
Everyone can undergo grief and loss, but not everyone has depression. depression differs from grief in that it involves a variety of additional symptoms, such as low self-worth, gloomy thoughts about the future, and suicidal ideation, whereas grief is characterized by feelings of emptiness, loss, and longing for a loved one with an intact capacity to experience pleasure. The way each person handles stress is different.
9. Can Chronic Pain Cause Depression?
Pain that lasts for several weeks to months is referred to as “chronic.” Chronic pain interferes with your ability to sleep, exercise, and be active, as well as your relationships and job productivity. Can you see how suffering from chronic pain may also make you feel down, alone, and depressed?
Depression and constant pain are both treatable. You may prevent your pain, get rid of persistent sadness, and begin your life again with the support of a comprehensive program that combines medication, psychotherapy, support groups, and additional services.
Conclusion.
In conclusion, there are many different causes of depression. It is not just because of one thing, but a mix of genes, body chemistry, environment, and how we think and feel. Some people are more likely to get depressed because of the genes or chemicals in their brains. Different life events like the loss of someone or being unhealthy can likewise make depression happen. Feeling alone, not having help, and society’s expectations can add to depression too.
Understanding the various causes of depression is important so we can find ways to prevent and treat it. We need to find depression early and help people learn about it. This includes using medicine and therapy, but also making changes to our lifestyle, having support from others, and not treating depression like something to be ashamed of.
We should all work together to make sure mental health is taken seriously and that people with depression get the help and support they need to live happier lives.
