Unexplained sadness can have various causes, ranging in severity from 'worrying' to 'very serious'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose unexplained sadness, we could:
premenstrual abdominal bloating
occasional racing thoughts
very low free T4
elevated TSH
missing outer third of eyebrows
history of frequent dieting
depression with some anxiety
yellow/yellowish fingernails
T3-only thyroid hormone use
much reduced sense of smell
regular sleep paralysis
frequent colds/flus| Cause | Probability | Status |
|---|---|---|
| Depression | 99% | Confirm |
| PMS D | 29% | Unlikely |
| Bipolar Disorder | 1% | Ruled out |
| Hypothyroidism | 0% | Ruled out |
|
Do you cry or become teary/sad for no reason?
