Symptoms of Acromegaly That Should Not Be Ignored
Persistent or progressive acromegaly symptoms, particularly when several occur together, should be assessed by a doctor. Here are some symptoms of acromegaly that should not be ignored:
| Symptom | What It May Indicate |
| Persistent or worsening headaches | Possible effects related to a pituitary tumour. |
| Changes in peripheral vision or loss of vision | Pressure on structures near the pituitary gland. |
| Increasing hand and foot size | Excess growth hormone and IGF-1 activity. |
| Breathlessness, especially with swelling or reduced exercise tolerance | Possible heart involvement or sleep apnea. |
| Severe or persistent joint pain | Changes affecting bones, cartilage and joints. |
| Persistent numbness or weakness in the hands | Nerve compression, such as carpal tunnel syndrome. |
| Excessive thirst or frequent urination | Possible high blood glucose. |
| Marked daytime tiredness with loud snoring or breathing pauses during sleep | Possible obstructive sleep apnea. |
Why Do Acromegaly Symptoms Occur?
Acromegaly develop because the body is exposed to high levels of growth hormone (GH) over a long period. In most cases, this happens due to a benign pituitary adenoma, a non-cancerous tumour in the pituitary gland that produces excess GH. The hormone stimulates the liver and other tissues to produce insulin-like growth factor 1 (IGF-1), which promotes the growth of bones, cartilage and soft tissues.
Over time, excess GH and IGF-1 cause the hands, feet, jaw and facial bones to enlarge, leading to noticeable changes in appearance. Thickening of soft tissues and cartilage contributes to enlarged lips and tongue, thicker skin, joint pain and stiffness. Swollen tissues may also compress nearby nerves, resulting in numbness, tingling or carpal tunnel syndrome.
The condition can also affect the heart, blood vessels and other organs. Long-term hormone excess may enlarge the heart muscle, increase the risk of high blood pressure and contribute to breathlessness or reduced exercise tolerance. In addition, GH can interfere with normal glucose metabolism, increasing the risk of insulin resistance and high blood glucose levels. A growing pituitary tumour may also press on nearby structures, causing persistent headaches or changes in vision.
Acromegaly symptoms usually develop gradually and may vary from person to person.
Symptoms of Acromegaly That Require Immediate Medical Attention
Acromegaly itself develops gradually, but some symptoms can indicate a serious complication or another urgent medical problem.
Seek immediate medical care if any of these symptoms appear:
-
Sudden or severe headache, particularly if it is different from previous headaches
-
Sudden loss or major change in vision
-
Severe difficulty breathing or significant breathlessness
-
Chest pain, fainting or severe weakness
-
Sudden confusion or loss of consciousness
-
Sudden neurological symptoms, such as new weakness or difficulty speaking
-
Severe symptoms suggesting a serious heart complication, such as marked breathlessness with chest discomfort
Symptoms of Acromegaly in Men
Men with acromegaly experience certain symptoms that are directly related to hormonal changes. The male-specific symptoms of acromegaly are as follows:
-
Erectile dysfunction
-
Reduced sexual desire
-
Infertility in some men
-
Fatigue and reduced energy levels
Symptoms of Acromegaly in Women
Women may develop the typical physical symptoms of acromegaly along with hormonal and reproductive changes. These symptoms may include:
-
Irregular menstrual periods
-
Absent periods in some cases
-
Reduced sexual desire
-
Changes in facial appearance
Symptoms of Acromegaly in Children
When excess growth hormone develops in children before the growth plates close, the condition is generally referred to as gigantism rather than adult acromegaly.
Possible signs include-
-
Unusually rapid growth in height
-
Height significantly above expected growth patterns
-
Enlarged hands and feet
-
Long arms and legs
-
Soft-tissue swelling
-
Delayed puberty
-
Headaches
-
Possible visual problems if a pituitary tumour affects nearby structures
A child or teenager showing unusually rapid growth should be assessed by a paediatrician or paediatric endocrinologist. Growth patterns should be interpreted using age and sex-appropriate growth charts rather than height alone.
Can You Have Acromegaly Without Symptoms?
Yes. Acromegaly can develop slowly, and early symptoms may be subtle or difficult to recognise. A person may not notice gradual changes in their facial appearance, hand size or foot size, particularly when these changes occur over many years.
Some people may first seek medical attention for symptoms such as headaches, joint problems, sleep apnea, excessive sweating, carpal tunnel syndrome, or changes in blood glucose levels. The condition may sometimes be identified when a healthcare professional notices physical changes or investigates related health problems.
When Can Acromegaly Symptoms Become Life-Threatening?
Acromegaly itself is usually a slowly developing condition, but untreated hormone excess can be associated with complications affecting several organs. These may include:
| Life-threatening Complications | What May Happen |
| Serious cardiovascular complications | Long-term excess GH and IGF-1 may contribute to high blood pressure and changes in the heart, which can increase cardiovascular risk. |
| Heart failure | In advanced cases, changes in heart structure and function may lead to breathlessness, reduced exercise tolerance and swelling. |
| Severe spnea | Significant obstruction of the upper airway during sleep can reduce oxygen levels and place additional strain on the cardiovascular system. |
| Major visual impairment | A large pituitary tumour may press on nearby structures and cause visual field loss. |
| Serious metabolic complications | Acromegaly can affect blood glucose regulation and may contribute to diabetes and related complications. |
How are Acromegaly Symptoms Diagnosed?
Symptoms alone cannot confirm acromegaly. A healthcare professional, usually an endocrinologist, may use a combination of clinical assessment, hormone testing and imaging to diagnose acromegaly. Check out the following table to know the diagnostic tests for acromegaly:
| Diagnostic Test | Purpose |
| IGF-1 blood test | Measures insulin-like growth factor 1, which is usually elevated when GH activity is persistently high. |
| Oral glucose tolerance test (OGTT) | Checks whether growth hormone is appropriately suppressed after glucose intake. |
| Growth hormone testing | Helps assess abnormal GH secretion when clinically indicated. |
| Pituitary MRI | Looks for a pituitary adenoma or other structural abnormality that may be causing excess GH production. |
| Visual field testing | Assesses vision when a pituitary tumour may be pressing on nearby visual pathways. |
| Additional hormone tests | Evaluate other pituitary hormones when pituitary function may be affected. |
FAQs
-
Q1. What is the first symptom of acromegaly?
Ans: There is no single first symptom of acromegaly that occurs in everyone. One or more symptoms may develop gradually over the years, such as changes in shoe or ring size, excessive sweating, headaches, etc. -
Q2. Can acromegaly develop without obvious symptoms?
Ans: Yes. Acromegaly often progresses slowly, and changes may be subtle at first. Some people may not recognise physical changes until they become more noticeable or are identified by a healthcare professional. -
Q3. Which acromegaly symptoms should never be ignored?
Ans: Persistent or worsening headaches, new vision problems, progressive enlargement of the hands and feet, severe joint symptoms and symptoms of sleep apnea should be medically evaluated. Sudden vision loss, severe headache, chest pain or severe breathing difficulty requires urgent medical attention.
