Physical Effects of Depression
We tend to think of depression as being a wholly mental illness. However, you might be surprised to know that there are also many physical effects of depression. Consequently, it’s worth knowing how these physical symptoms present so that you can recognize the warning signs should they affect you.
Fatigue
Feeling tired is a really common symptom of depression, but it’s also a really common symptom of a whole host of other illnesses including anemia and lupus too. This is why it’s a good idea to speak to a medical professional if you’re feeling tired. Once the physical causes have been ruled out, you can explore the possibility that you may be feeling depressed. From there you can get the help and treatment you need to start feeling better again.
Digestive problems
The gut and the brain are far more closely linked than you might have imagined. In fact, digestive specialists like Dr. Shakeel Ahmed of St. Louis often refer to the gut as the second brain. This means that, quite often, issues in the gut or with the digestive system, can actually cause depression. So, if you’re constantly suffering from abdominal pains, diarrhea, constipation, or other common digestive issues, don’t rule out the possibility of depression. However, you should also get checked out for physical illnesses too.
Pain
Some people, when they are experiencing a period of depression, notice that their pain tolerance is a lot lower than it usually is. They get far more aches and pains than usual. These seem to have no cause. No one quite knows why this should be the case, but if you’re feeling low and you’re hurting physically, it may be that the two things are linked.
Headaches
We all get headaches from time to time. Most of us ignore them apart from taking some sort of relief or taking a nap. However, we may want to rethink that approach. Headaches can be one of the physical effects of depression. If you notice that you’re having more headaches than usual, it’s easy to panic but you may not actually be physically ill. It could be a mental problem that you need help with, Again, it is important that you rule out all possibilities both physical and mental as a precaution.
Addiction
The sad truth about depression is that addiction often gets linked with it. Figures from the Substance Abuse and Mental Health Services Administration suggest nine million American adults have a dual depression and addiction diagnosis.
Getting the right therapy for addiction will help ease and eventually eradicate the damage it physically causes the body. For example, alcohol addiction can lead to many long-term health risks like liver cancer, high blood pressure, and strokes.
When getting treatment for addiction, part of the therapy process that can help includes looking at sober living homes for men and women.
Vision issues
Some people with depression report that the world around them looks more blurry than it did before. One German study concluded that depression can indeed affect eyesight. Scientists call this phenomenon “contrast perception” and it is much more common than you may think. Contrast perception gives the world a hazy look.
There are many physical effects of depression but it is important not to ignore any physical problems you may be experiencing too. Explore all avenues and you’ll get the best results for your health and wellbeing.

Vision and digestive problems are so apparent. I experienced it lately when I was depressed. We should really take mental health seriously!
We really should. Physical and mental health are completely intertwined but when someone is physically sick they get much less judgment than when they are having an issue that is in the mental realm of wellness.
Thank you for the insightful information, Dr. Elise! I know depression has big physical impacts on a person but it’s good to know how it is manifested.
You are very welcome, Ivan. Knowledge is power.
Thank you for sharing this! I can then use this list to ask a friend who might be going through something.
You’re welcome. You are a very caring friend.
Your post gave some insight that I think needed to recheck myself… I been seeing things blurry… I may have to rethink this thanks!
You are very welcome. Definitely look into that blurry vision. Even if yours is not an indicator of something emotional it is still much nicer to see the world clearly.
I have all of these! It’s interesting to know how much depression really affects you physically.
Heather, it really does. The body and mind are completely intertwined. Take care and reach out if I can be of help.
You are correct- we don’t normally think of depression as something that impacts our physical health. But now that I read this, certain things make sense, like digestion. I would never have guessed that it impacts vision, but now I know!
Isn’t it fascinating, Bryan? Everything is so intertwined.
I’m so glad you shared this. So many people look at depression is simply being sad or blue, but there is so much more to it than that.
Kuntala, you are so right. The thing is that it is really a spectrum and it can look different from one person to the next.
Can relate. I had a time when I couldn’t eat well, and I couldn’t figure out why. Eventually figured that it’s because of my mental and emotional state.
You are connected to your body and were able to recognize the issue. It is wonderful to hear that you are much better now.
Very insightful read! I think we can take preventative steps if we do experience these symptoms.
Yes, we absolutely can take preventative steps. Prevention is actually the best as that is much easier than recovery.
Great read. I have learn a lot from this article and understanding the symptoms helps us to manage depression in a right way. Thank you!
I am happy that you found value here. Thank you.
