In answer to your question...Yes, any medical problems can lead to depression and anxiety disorders. In most cases it can be temporary and treated with a short stint with antidepressants for temporary periods. But for long term long-term illnesses depression is known to hang in there for the long haul.
I have had depression, anxiety and panic since I was a child due to abuse issues. However, I was diagnosed with MS when I was 26 in 2001, which of course made the depression much worse. And harder to be treated with the medication I was already taking at the time. Within the last year I have also developed another serious disorder that messes with my blood pressure and heart rate. So once again depression was at an all time high and had to change meds. The thing for me that was hardest to learn was diet and exercise to maintain health. I have always been thin and never had to watch my weight so what I ate wasn’t a factor before, neither was exercise. My cardiologist and Psychiatrist get together on my medication regime regularly due to the blood pressure factor mostly, but they both push the exercise and diet strongly. And I’m surprised it does help greatly with depression and total overall health.
I do have some stomach problems with the amount of pills I take but I don’t feel it is stress related and all tests have come back fine that have been ran. However, my 10 year old niece who lives in a very unstable home with her single mother who has a drug addict boyfriend that steals all their belongings all the time (he just got out of prison yesterday) has a lot of stomach problems. I do think this is due to her anxiety and nerves. The brain is a very powerful place and it does essentially control every part of our bodies.
