In May 2024 we published a detailed article that explains why acromegaly often causes muscle weakness and what you can do about it. If you noticed growing fatigue, weaker grip, or trouble climbing stairs, this summary points you to practical steps and the tests doctors use.
Acromegaly happens when the pituitary gland makes too much growth hormone, usually from a small tumor. The extra hormone slowly changes your bones, skin, and muscles. Signs you might recognize: larger hands or feet, coarser facial features, and joint pain. Muscle weakness often shows up as tiredness, trouble rising from a chair, or lower strength in the hips and shoulders.
Diagnosis starts with a blood test for IGF-1, a marker that stays steady through the day. If IGF-1 is high, doctors usually do an oral glucose suppression test to see if growth hormone levels fall as they should. An MRI of the pituitary confirms whether a tumor is present and helps plan treatment. Vision checks are common because tumors can press on the optic nerves.
Early detection matters because the changes are slow but progressive. If you have persistent symptoms — worsening muscle weakness, new headaches, or changes in vision — see a specialist. Treating the cause often helps the muscle problems over time.
Surgery to remove the pituitary tumor is the most common first step when feasible. Many people feel relief after surgery, but some need medication or radiation too. Medicines include somatostatin analogs (like octreotide or lanreotide), dopamine agonists, and a growth hormone receptor blocker called pegvisomant. Your doctor will tailor the plan to your test results and symptoms.
Alongside medical treatment, physical therapy is very useful. A focused program can rebuild strength in the hips, shoulders, and thighs — the places most affected. Simple, consistent exercises done three times a week help more than sporadic effort. Aim for a mix of resistance work, balance practice, and light aerobic activity to fight fatigue and prevent falls.
Diet and supplements can support recovery. Prioritize protein and ensure you have enough vitamin D and calcium if bone or joint issues are present. Sleep apnea is common with acromegaly, so if you snore loudly or wake gasping, get evaluated; treating sleep apnea often improves daytime weakness and energy.
The May 2024 article breaks down symptoms, the testing pathway, treatment options, and realistic at-home steps to stay stronger. If you or a loved one is coping with unexplained muscle weakness and other signs mentioned above, read the full post for clear next steps and questions to ask your doctor.
