Key Takeaways
- The most common symptom is enlargement of hands and feet, reported in 88-100% of patients
- Facial changes such as coarsening of features occur in 95% of acromegaly patients
- Excessive sweating (hyperhidrosis) is present in up to 80% of cases
- Diagnosis of acromegaly requires elevated insulin-like growth factor 1 (IGF-1) levels above age- and sex-matched normal ranges
- Random growth hormone (GH) levels greater than 1 ng/mL after oral glucose tolerance test (OGTT) confirm diagnosis in 95% sensitivity
- IGF-1 measurement has a sensitivity of 96-100% for acromegaly diagnosis
- Acromegaly has a prevalence of approximately 40 to 130 cases per million population worldwide
- The annual incidence rate of acromegaly is estimated at 3 to 4 new cases per million people per year
- In the United States, about 3,000 to 4,000 new cases of acromegaly are diagnosed annually
- Untreated acromegaly reduces life expectancy by 10 years
- Cardiovascular disease causes 50-60% of deaths in acromegaly patients
- Normalized IGF-1 levels increase 10-year survival to near-normal
- Transsphenoidal surgery achieves biochemical remission in 50-70% of microadenomas
- Somatostatin analogs like octreotide reduce GH/IGF-1 by >50% in 50-70% of patients
- Cabergoline normalizes IGF-1 in 30-40% of mild cases
Acromegaly affects about 40 to 130 per million people, with swollen hands and feet reported in up to 100%.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
