A Closer Look at Depression: Physical Effects and Long-Term Health Risks

More than 18% of American adults experience depression, making it the most common mental health condition in the country. Although depression primarily affects your mental well-being, did you know that it can also seriously impact your physical health, too?

Depression is far more than sadness or lack of motivation, and it can have real, long-lasting effects on your entire body. This Mental Health Awareness Month, our team at Ross Medical Group is taking a closer look at the lesser-discussed symptoms of depression and how seeking help is the first step to feeling better mentally, emotionally, and physically.

Understanding the physical effects of depression

Depression doesn't just make you feel sad — it changes how your body functions. Persistent fatigue and exhaustion, low energy, and changes in sleep patterns are common symptoms. Changes in appetite, unexplained aches and pains, and even stomach problems can develop.

These physical symptoms are just as real and debilitating as the emotional ones, yet they're often dismissed or attributed to other causes. Here are a few different ways depression impacts your body.

Cardiovascular health

Depression increases your risk of developing heart disease, even if you don't have traditional cardiovascular risk factors. That’s because depression can elevate your blood pressure, increase inflammation throughout your cardiovascular system, and affect how your blood vessels function. If you already have heart disease, depression can increase your risk of serious complications.

The stress hormones your body releases when you experience depression strain your heart, alter your heart rhythm, and promote the formation of arterial plaque. Depression also makes you less likely to follow heart-healthy behaviors like exercising, eating well, and taking medications as prescribed, which compounds your cardiovascular risk.

Metabolic and endocrine changes

Depression interferes with metabolic processes throughout your body. It can increase your risk of developing type 2 diabetes, because it changes how your body processes insulin and regulates blood sugar.

Untreated depression can also impair thyroid function, which often creates a vicious cycle where thyroid problems worsen depression and depression affects thyroid health. Chronic stress from depression can put your body’s inflammatory response into overdrive, which impacts your weight, immune function, and more.

Neurological and cognitive effects

Along with the characteristic feelings of sadness, depression actually changes your brain structure and function. Chronic depression can shrink certain brain regions, particularly those involved in memory and emotional regulation.

You might experience difficulties with concentration, decision-making, and memory that go beyond simple distraction. Depression may also increase your risk of developing dementia later in life, particularly if it goes untreated for many years.

Pain amplification

Depression affects pain in two ways. It both lowers your pain threshold and amplifies pain signals throughout your body.

If you have chronic pain conditions like arthritis, fibromyalgia, or migraine, depression may make that pain worse and harder to treat. Conversely, chronic pain often triggers or worsens depression, creating a feedback loop where each condition intensifies the other.

Immune system compromise

Depression can also suppress immune function, making you more vulnerable to infections and slower to heal from injuries and illnesses. The chronic stress and inflammation associated with depression interfere with your immune system's ability to protect you effectively.

If you think you might have depression

The physical impacts of depression might sound worrisome, but the good news is that depression is treatable — and treating it often brings improvement in mental, emotional, and physical symptoms.

If you are experiencing persistent sadness, a loss of interest in activities you once enjoyed, feeling worthless or hopeless, or having thoughts of death or suicide, you need to seek help, and your primary care provider is an excellent starting point.

Our team at Ross Medical Group is equipped to screen you for depression, discuss your symptoms, evaluate for physical conditions that might be contributing to your symptoms, and provide initial treatment, including medication and lifestyle recommendations. You don't need to see a psychiatrist first or navigate complex mental health systems on your own.

We also coordinate referrals to mental health specialists when needed, monitor your progress and adjust treatment as necessary, and address the physical health consequences depression may be causing. Depression often coexists with other chronic conditions we manage, so we take a comprehensive approach to your overall health.
