Mental health has many interactions with other areas of health. Sometimes symptoms from different diagnoses are similar, which is why it is not possible to make a diagnosis directly. Therefore, there can also be interrelationships with other diseases. For example, a life-threatening illness such as cancer can also trigger depression, or an anxiety disorder can be the trigger for stomach problems or pain.
Just as there is a connection between mental and physical illnesses, mental illnesses can also reinforce or condition each other. For example, depression can increase other phobias or issues.
