Acromegaly is a rare hormonal disorder characterized by excessive GH production. Understanding the causes, recognizing the symptoms, and seeking timely medical intervention are crucial for effective management. By doing so, individuals who suffer from acromegaly can improve their symptoms and reduce potential risks of complications.

What is Acromegaly?

Acromegaly is a hormonal disorder that occurs when body is producing excessive amount of growth hormone (GH). This extra amount of GH leads to excessive growth in the bones and soft tissues throughout the body. In children with this condition, abnormal height and an exaggerated bone structure may occur. Acromegaly primarily impacts the arms, legs, and face. 

Causes of Acromegaly

Generally the main cause of acromegaly is a benign tumor known as a pituitary adenoma. These tumors stimulate the pituitary gland to produce an excess of GH, leading to the development of acromegaly. In rare instances, nonpituitary tumors in other parts of the body may also contribute to the excessive GH production. 

Acromegaly Symptoms

Acromegaly symptoms develop gradually and can change from one person to another. There are some common signs like enlarged hands and feet, changes in facial features such as a protruding jaw or enlarged nose, thickened skin, joint pain and limited mobility, excessive sweating and body odor, fatigue, headaches, vision problems, and menstrual irregularities in women.

Diagnosing Acromegaly

Diagnosing acromegaly involves a combination of medical history evaluation, physical examinations, and specialized tests. Levels of GH and insulin-like growth factor 1 (IGF-1), which is a hormone influenced by GH, can be determined by blood tests. Imaging studies such as X-rays, MRI scans, and sonograms may be ordered to assess bone growth and identify the presence of pituitary tumors. 

Acromegaly Treatment

The treatment of acromegaly aims to normalize GH production, relieve symptoms, and reduce the risk of complications. The primary treatment options include:

  • Surgery: The surgical removal of the pituitary tumor causing excess GH production is often the first-line treatment. This procedure can effectively reduce GH levels and improve symptoms. In some cases, additional surgery or radiation therapy may be required.
  • Medication: Medications such as somatostatin analogs, GH receptor antagonists, and dopamine agonists can be prescribed to regulate or block GH production, shrink tumors, and alleviate symptoms. These medications are often used when surgery is not completely successful or before surgery to reduce tumor size.
  • Radiation Therapy: Radiation therapy may be used to destroy remaining tumor tissue after surgery or when medications alone are insufficient. It can gradually lower GH levels, but the full effects may take several years to be observed. Radiation therapy carries certain risks and potential complications.

Potantial Risks of Acromegaly

Unless being treated properly for a long time, acromegaly can lead to serious health problems and complications. Some common complications include high blood pressure, heart problems, diabetes, osteoarthritis, goiter, sleep apnea, increased risk of cancerous tumors, vision changes or loss, and spinal cord compression or fractures. Early diagnosis and appropriate treatment can help prevent or minimize these complications. 

Frequently Asked Questions

Can Acromegaly be reversed?

Acromegaly cannot be fully reversed, but early diagnosis and treatment can help control symptoms and prevent further progression of the condition.

Is Acromegaly genetic?

Eventhough it is not hereditary, certain gene mutations may increase the risk of developing pituitary tumors, which can lead to acromegaly.

Is Acromegaly fatal?

As mentioned above, without proper management and treatments, acromegaly can lead to severe complications and an increased risk of mortality. However, with timely intervention and appropriate treatment, the prognosis for individuals with acromegaly can be significantly improved, reducing the risk of fatality.
