Pain and body image drive Cushing’s depression more than hormones
Addressing physical changes promptly could protect a patient's mental health

Chronic pain and body image issues, not hormonal shifts, are the primary drivers of depression in people with Cushing’s syndrome, a new study finds.
For many patients, the mental health toll of the rare disorder is shaped more by physical suffering and self-perception than by high cortisol levels. Therefore, treating their depression requires not only balancing hormones, but also a focused approach to managing physical pain and the psychological impact of the disease’s physical changes, researchers note. By addressing these factors early, healthcare providers may be able to prevent long-term mental health challenges for people living with Cushing’s.
The study, “Changes in Body Image and Pain in Patients with Cushing Syndrome: A Predictor for Depression and Vice Versa,” was published in the Journal of the Endocrine Society.
Cortisol levels and physical measurements
Cushing’s syndrome refers broadly to disorders marked by high levels of the stress hormone cortisol, which drive symptoms such as weight gain, skin changes, and fatigue. Cushing’s disease is a specific form of the syndrome and is caused by a tumor in the pituitary gland.
Although depression is one of the most common Cushing’s symptoms and can take a major toll on patients, not everyone who has the condition develops depression, and it’s not clear why.
Seeking to better understand the triggers for depression in Cushing’s, scientists analyzed data from the German Cushing registry. The study included 90 people with Cushing’s syndrome, most of whom had Cushing’s disease, and 200 people who were thought to have Cushing’s based on symptoms but were ruled out by laboratory tests.
At the time of their diagnosis, nearly half (44%) of the Cushing’s patients met diagnostic criteria for depression based on standardized tests. However, 30% of these individuals self-reported any history of depression. This discrepancy “highlights the importance of depression screening in patients with [Cushing’s syndrome],” the researchers wrote.
The scientists conducted statistical tests to see if depressed patients tended to show differences in clinical measurements, such as cortisol levels and weight. However, these tests failed to identify any statistically meaningful associations.
“When analyzing patients with [Cushing’s syndrome] by depression status at time of diagnosis, no statistically significant differences were found in biochemical parameters, sex distribution, or body measurements,” the researchers wrote. These data suggest that physical changes like altered cortisol levels can’t be the only thing that determines whether or not Cushing’s patients develop depression.
The link between pain and body image
The researchers then analyzed long-term data from 25 patients — 15 with persistent depression and 10 without — who were followed for four years on average. The scientists found that Cushing’s patients with depression were much more likely to report chronic pain. Patients who were not depressed generally didn’t report any pain, whereas those with depression rated their pain as 5 out of 10 on average, and were more likely to report substantial body image issues.
The researchers also noted that pain and body image issues were closely correlated. In other words, patients who reported more pain also tended to report feeling worse about their body, and vice versa.
“The findings of our study indicate a statistically significant relationship between pain, body image perception disturbance, and the development of depressive symptoms,” the researchers concluded.
Based on their findings, the scientists called for efforts to give better support to people with Cushing’s who are coping with pain and/or body image issues, as dealing with these problems could help improve long-term mental health.
“Pain and dissatisfaction with physical changes, particularly with the altered functionality of the body in daily activities, should be promptly addressed,” the researchers wrote. “This approach may help to prevent the manifestation of persistent depression and its associated consequences.”
