Depression is one of the most prevalent mental health conditions in the world today. It’s characterized by persistent feelings of sadness and hopelessness, as well as a lack of interest and motivation in everyday life. What many do not realize, however, is that depression is more than “feeling sad.” It can last for several weeks, months, or even years—taking a toll on a person’s mind and body.
In fact, research shows that depression often manifests through physical symptoms, such as aches and pains, and is associated with the development of chronic health conditions.
In this guide, we’ll review the disabling effects of depression on the body and explore why depression and physical health are so closely related. Let’s dive in.
The Link Between Depression and Physical Health
Have you heard the phrase “mind-body connection” before? Mind-body connection refers to the bidirectional relationship between a person’s mental health and physical health. It’s an evidence-based understanding that thoughts and emotions have the power to influence a person’s physical state. For example, chronic stress and sadness can trigger illness and pain.
As we think about the effects of depression on the body, this is especially pertinent.
Depression lives inside the brain, affecting how a person thinks, feels, and behaves. It disrupts the brain’s chemical make-up and reduces hormones like dopamine and serotonin, which help people find pleasure and regulate their moods. On top of this, though, depression causes the brain to function in a state of stress response. It increases cortisol levels, in turn leading to physical issues like chronic inflammation, a weakened immune system, extreme fatigue, and disrupted sleep.
People battling depression often struggle to get out of bed, and when you understand this connection, it’s easy to see why. Depression isn’t just a low mood. It’s not just “all in the head.” Depression can feel physically heavy, exhausting, and even painful for those suffering.
The Physical Effects of Depression
Now that we understand the “why” behind the physical symptoms, let’s get back to the original question: What does depression do to your body, exactly?
The answer can be broken down into two categories: short-term symptoms and long-term effects.
Short-term physical symptoms of depression:
When a person is actively experiencing depressive episodes, their body will feel it. These symptoms make it difficult to function effectively and enjoy daily activities. They can last for two weeks or longer, but often fluctuate in intensity, coming and going over the course of one’s condition.
Short-term physical effects of depression include:
- Extreme fatigue and low energy, even after rest
- Sleep disturbances, including insomnia and hypersomnia
- Frequent restlessness
- Body aches and pains without explicable cause
- Tension headaches and neck/shoulder pain, due to constant stress
- Digestive problems, such as nausea and bloating
- Sudden appetite and weight changes
- Slowed movement, speech, and decision-making
While the bodily effects of depression can ebb and flow, they can quietly build in the background and create long-term issues with a person’s physical health. For example, a lack of sleep over time can contribute to a greater risk of hypertension, heart disease, diabetes, stroke, and other medical conditions. Frequent digestive issues can contribute to disorders like IBS (irritable bowel syndrome). And, beyond these, depression itself has been connected to chronic health conditions, which we detail below.
Long-term effects of depression on the body:
When depression is persistent, chronic, and/or left untreated, its impact can extend far beyond mood. Ongoing changes in stress hormones, inflammation, sleep patterns, and daily behaviors can gradually pile up—disrupting multiple systems in the body and leading to more serious health conditions.
Specifically, depression can increase a person’s risk of long-term health conditions like:
- Alzheimer’s disease
- Autoimmune diseases
- Cardiovascular disease
- Chronic pain conditions
- Diabetes
- Endocrine issues
- Osteoporosis
- Stroke
- Substance abuse disorders
Additionally, untreated depression can interfere with a person’s immune function, making the body more vulnerable to illness long-term. People with chronic depression tend to get sick more often, take longer to recover from infections, and face an increased risk of inflammatory or autoimmune conditions.
Outside of the biological connection between physical and mental health, the National Institute of Mental Health (NIMH) explains that people with untreated depression can struggle to take care of themselves. They may have trouble completing healthy tasks, like eating well and exercising, due to physical symptoms like fatigue. They may not have the energy or motivation to make medical appointments, prioritize self-care, or address physical issues that arise. Over time, avoidance can compile, resulting in a greater risk of physical disease.
Treating Depression is Key to Your Overall Health
If you are here now, you may be familiar with the symptoms of depression. You (or your loved one) might struggle to get two feet on the floor in the morning. You might lack every desire to take a shower, to exercise, or simply to go outdoors. However, taking these steps is important.
To prevent your physical health from deteriorating, you must prioritize your mental health. For many people with depression, this means getting professional support. Depression is highly treatable, and the physical effects of depression can be managed or mitigated over time. This is typically done through a combination of approaches, including:
- Therapy, including evidence-based methods like Cognitive Behavioral Therapy
- Medication, to help regulate and address chemical imbalances in the brain
- Lifestyle or behavioral changes, such as sleeping, eating, and exercise habits
Through these methods, integrated depression treatment can help you heal your mind, restore your energy, improve your sleep, reduce pain, and bring your body back to a healthier baseline.
You do not have to manage the symptoms of depression alone. Your mind, and your body, deserve to heal. Contact Turnbridge today at 877-581-1793 to see how we can help you on the path to recovery.
