Acromegaly is a rare hormonal disorder caused by a benign tumor (adenoma) on the pituitary gland that produces too much growth hormone (GH), which in turn drives the liver to overproduce insulin-like growth factor-1 (IGF-1). The excess GH and IGF-1 cause gradual physical changes, including enlarged hands and feet, coarsened facial features, joint pain, and complications such as sleep apnea, high blood pressure, diabetes, and heart problems. Acromegaly is genuinely rare, affecting roughly 3.8 people per million each year, with total prevalence now estimated around 120 per million. Because the changes develop so slowly, many people live with symptoms for 5 to 10 years before they are correctly diagnosed, a diagnostic delay that can take a real emotional toll long before treatment even begins.
What the Research Shows
A 2025 study published in Pituitary followed 105 people with acromegaly and compared them to 211 people with a different, hormone-inactive type of pituitary tumor (NFPA), a comparison group that let researchers isolate the effect of growth hormone excess itself, not just having a pituitary tumor. People with acromegaly were nearly twice as likely to be diagnosed with depression (relative risk 1.9, 95% CI 1.2–3.2), with about 1 in 4 people with acromegaly in this study receiving a depression diagnosis. They were also far more likely to need inpatient psychiatric hospitalization: 5.7% versus just 0.5% of the comparison group. The same research team pooled their findings with seven other studies (over 1,300 people total) and found a consistent pattern: depression risk nearly double (RR 1.8, 95% CI 1.3–2.5) and anxiety risk nearly double as well (RR 1.9, 95% CI 1.1–3.2) compared to other pituitary tumor patients. Notably, the anxiety link did not reach statistical significance in this research team's own smaller study alone (RR 1.4, 95% CI 0.5–4.4), a reminder that single studies can be underpowered even when the broader body of pooled evidence points clearly in one direction.
Coping Strategies
- Track your symptoms and your mood together. Keeping a simple log of physical symptoms like joint pain, fatigue, and sleep quality alongside your mood can help you and your care team see patterns and know when a dip might be linked to a physical flare rather than just stress.
- Build a care team that talks to each other. Acromegaly care usually centers on an endocrinologist, but asking them to loop in a mental health professional, ideally one who understands chronic hormonal conditions, can help catch psychiatric symptoms earlier.
- Do not dismiss joint pain as something you just have to live with. Persistent arthropathy, or joint damage, is common in acromegaly and is strongly linked to depression risk in research, so treating the pain itself is often a meaningful step toward protecting your mental health too.
- Connect with others who have acromegaly specifically. Because the condition is so rare, many people have never met another person with it. Patient organizations and online communities can meaningfully reduce the isolation that comes with a rare, often invisible illness.
- Give yourself permission to grieve physical changes. Changes to your hands, feet, and facial features are real losses, even after your hormone levels return to normal, and it is okay to feel sad or frustrated about them.
A Surprising Pattern: Symptoms That Emerge After Treatment Succeeds
One of the most striking findings in acromegaly research is a kind of delayed reaction. In the 2025 cohort study, the median time between a person's pituitary diagnosis and their psychiatric diagnosis was about 6 years, and by that point roughly 90% of participants had already achieved biochemical control, meaning their GH and IGF-1 levels were back to normal. Strikingly, IGF-1 levels at the time did not differ between people who went on to develop a psychiatric diagnosis and those who did not. In other words, it was not ongoing active disease driving the mental health symptoms; something else was happening well after the tumor was successfully treated. The study's authors raise an intriguing hypothesis: a withdrawal phenomenon, in which the body and brain, having adapted to years of excess growth hormone, struggle during the transition back to normal hormone levels. They compare this to the emotional crash some people experience after stopping long-term androgen use, or after surgery for a different hormone-excess condition called Cushing's disease. If you have successfully treated your acromegaly but notice your mood declining years later, this research suggests you are not imagining things, and it is worth raising with your care team even if your hormone levels look perfect on paper.
Pain, Body Image, and Emotional Wellbeing
Two connected threads stand out in the research. First, chronic pain: in the same cohort, 28% of people with acromegaly who also had a psychiatric diagnosis were using opioid medication daily, usually for joint pain linked to arthropathy, and researchers describe pain and depression as feeding into each other, with pain often predicting worsening depression over time rather than simply the reverse. Second, body image: the visible physical changes caused by acromegaly, including enlarged hands and feet and a coarsened facial appearance, can be genuinely distressing, and earlier research found that women with acromegaly reported significantly more body image concerns, weight-related worry, and avoidance behaviors than men. A small number of people in the 2025 study had a co-occurring eating disorder, and all of them were women who also had depression. If you notice your relationship with food, your body, or physical pain shifting alongside your acromegaly, these are not separate issues to push aside; they are worth raising directly with both your endocrine and mental health providers.
Advocating for Yourself
- If changes are gradual, trust what you notice. Because acromegaly develops slowly, friends and even doctors sometimes miss it for years. If your hands, feet, or facial features have changed, or rings and shoes no longer fit, ask your doctor specifically about a growth hormone and IGF-1 blood test.
- Ask for an IGF-1 test by name. This is the standard screening blood test for acromegaly. It is inexpensive and can be requested even if you are unsure acromegaly is the cause of your symptoms.
- Mention snoring, fatigue, and joint pain together. These symptoms are common and easy to dismiss individually, but mentioning them as a cluster, alongside any changes in hand or foot size, gives your doctor more to work with.
- Mental health symptoms years after treatment still count. If you were treated for acromegaly years ago and are now struggling emotionally, do not assume it is unrelated just because your hormone levels are normal now. Bring your full history to a mental health professional.
- Seek support designed for rare conditions. Because acromegaly is rare, general chronic illness support groups may not fully capture your experience. Look for acromegaly-specific patient organizations when possible.
