The short answer is “many”.
The long answer however, is somewhat variable; because the severity of different psychological conditions can have varying effects on your health. Recently, the most widespread psychological illness sweeping most of the world is depression.
Aside from being one of the toughest ailments to diagnose, it’s harder to treat as well. The fundamental reason behind this fact is how frequently depression and physical ailments can combine together to hide each other’s symptoms; making the assessment of the core issue an even more difficult matter. Similarly, minor physical ailments can trigger depression which further increases the severity of the condition.
According to one study, 65% of people suffering from depression complain of pain on different parts of their bodies. These chronic pains are manifestations of continued depression that has been observed among a large portion of the world’s population. And this inadvertently triggers a vicious cycle where the depression and physical ailment feed off each other. It’s been said that the rate of depression in patients with chronic diseases tends to be 3 times higher than normal individuals.
More than 69% of individuals suffering from depression consult their doctors for pains. Some of the most common ones are Migraines, digestive problems, joint pains, chest pain and back pain. However the most worrying manifestation of depression is anxiety which directly affects the rhythm of your heart. If left untreated, this ailment can expand and may put you at risk of coronary heart disease due to increased blood pressure, cholesterol and stress hormones.
However all is not lost. The power of your psychological states can significantly help reduce the perceived effects of any physical ailments you may be suffering. Although that’s easier said than done, we must ensure to keep ourselves engaged in hobbies that directly speak to our sense of self-worth, which will keep us positive and avoid having a minor physical sickness spiraling out of control.
