Not seeing your symptoms? No worries!
A condition caused by abnormally high levels of growth hormone in the blood. It is typically caused by benign (non-cancerous) tumors in the brain. It can present as abnormally large hands and feet and greater than average height.
Your doctor may ask these questions to check for this disease:
Treatment generally aims to remove the tumor and stop its effects - this can be done by surgery or radiation therapy. Medications can also be given to shrink the tumor and block the effects of high growth hormone levels.

Q.
Hormones Off? Why Hypothalamus Function Matters + Medical Next Steps
A.
Hormone symptoms can start in the hypothalamus, the brain’s control center that directs the pituitary and influences thyroid, cortisol, growth and sex hormones, fluid balance, metabolism, sleep, fertility, and temperature, so issues may appear as weight changes, fatigue, sleep disruption, irregular periods or libido changes, fertility problems, temperature intolerance, or gradual enlargement of hands and feet. There are several factors to consider. See below to understand more. Key next steps include tracking symptoms, asking your clinician for a comprehensive hormone panel (TSH/Free T4, morning cortisol and ACTH, LH/FSH, sex hormones, prolactin, IGF-1), pursuing a pituitary-focused MRI and endocrinology referral if central causes are suspected, considering an acromegaly symptom check for gradual enlargement, and seeking urgent care for sudden severe headache, vision changes, confusion, severe dehydration, or rapid unexplained changes.

Q.
Is it a Habsburg Jaw? Why your jaw protrudes and medical next steps.
A.
There are several factors to consider. A protruding lower jaw is usually mandibular prognathism, most often inherited or due to growth or dental alignment, but new or worsening changes in adulthood with signs like enlarged hands, tooth spacing, headaches, or vision issues can signal treatable acromegaly that needs prompt evaluation. Next steps include seeing a dentist or orthodontist for bite assessment and imaging, and if adult-onset changes are suspected, asking a doctor about IGF-1 blood tests and a pituitary MRI; treatments range from no treatment to orthodontics to jaw surgery, with important details and decision points explained below.

Q.
Is your body changing? Why your features grow and Acromegaly next steps.
A.
Progressive enlargement of your hands, feet, or facial features in adulthood can signal acromegaly, a rare excess growth hormone condition usually from a pituitary tumor, which can also bring headaches, joint pain, carpal tunnel, snoring or sleep apnea, high blood pressure, and diabetes. Next steps: compare old and recent photos, write down symptoms, and ask a clinician to check IGF-1 with possible glucose suppression testing, followed by a pituitary MRI if indicated; early treatment with surgery, medication, or radiation can prevent complications and often restores near normal life expectancy. There are several factors to consider that could change your plan, including red flags like vision changes or severe headaches that need urgent care, so see the complete guidance below.
