Patients with depression should consult psychology or psychiatry, but many patients who first get depression do not know it is depression, such as some patients who have headaches and consult neurology, some people who are depressed manifest as bad digestive system, such as not wanting to eat, bloating, nausea, and repeatedly see gastroenterology. Some other patients have throat discomfort and feel that they cannot spit out or swallow something in their throat, and they suspect esophageal cancer or pharyngitis, so they may consult the department of quinturology and stomatology again. Many people see TCM repeatedly because they cannot find out the cause. TCM may solve part of the problem, but patients with major depression must be treated by Western medicine. If there is no organic disease and it cannot be explained by modern medicine, we should consider whether it is depression or not, and then we should choose to go to psychology or psychiatry.
