Acromegaly often goes unnoticed for years. People slowly develop larger hands, wider faces, and joint pain, and those changes get blamed on aging. The most common cause is a small pituitary tumor that pumps out extra growth hormone. Treating it early reduces the risk of heart, sleep, and metabolic problems.
If you or your doctor suspect acromegaly, testing starts with a blood test for IGF-1 (insulin-like growth factor 1). High IGF-1 suggests excess growth hormone. Next is an oral glucose tolerance test: growth hormone normally drops after sugar — if it doesn’t, that’s a strong sign. Finally, an MRI of the pituitary checks for a tumor and guides treatment planning.
Don’t ignore common early clues: thicker skin, increased shoe or ring size, frequent headaches, vision changes, sleep apnea, and new-onset diabetes or high blood pressure. Bring photos from years ago if you can — they can make changes obvious.
Surgery is often the first step. A neurosurgeon can remove the pituitary tumor through the nose (transsphenoidal surgery). Many people see hormone levels drop quickly after a good resection.
If surgery doesn’t cure the condition or can’t be done, medicines help. Somatostatin analogs (like octreotide or lanreotide) reduce growth hormone release. Pegvisomant blocks hormone action at the liver and lowers IGF-1. Dopamine agonists (e.g., cabergoline) work for smaller tumors or milder cases. Radiation therapy is an option when surgery and drugs aren’t enough, but it works slowly and needs long-term follow-up.
Living with acromegaly means regular checks: IGF-1 tests, MRI scans, and monitoring for heart disease, sleep apnea, diabetes, and joint problems. Ask your team about screening schedules and whether you need specialist referrals (cardio, sleep clinic, dentist, or orthopedics).
Simple steps help day-to-day: manage blood sugar, get tested for sleep apnea if you snore or feel very tired, and tell dentists about jaw changes before dental work. If you’re starting medical therapy, learn the side effects (gut upset with somatostatin drugs, rare injection-site issues, or changes in liver tests with pegvisomant) and report them early.

If you notice growing features, persistent headaches, or new metabolic issues, see an endocrinologist sooner rather than later. Early diagnosis makes treatment simpler and cuts the chance of long-term problems.
