Difference Between Gigantism and Acromegaly Explained Simply

It is important for one to understand the difference between gigantism and acromegaly since both are diseases that occur from hormonal imbalance leading to excessive growth. Gigantism and acromegaly are rare diseases that are triggered by excessive growth hormones associated with a growth hormone disorder.

In this article, we shall try to understand the difference between gigantism and acromegaly, how to identify, symptoms, diagnosis, and treatment of these two illnesses.

What Is a Growth Hormone Disorder?

This is a situation whereby a person experiences hormonal imbalance where there is an increase or decrease in growth hormone levels. GH is produced in the pituitary gland and is vital for growth, metabolism, and body composition among other functions.

In cases like gigantism and acromegaly, excessive GH production is always brought about by a benign tumor in the pituitary gland. They are identified using symptoms like headaches and hormonal imbalance.

Differences Between Gigantism and Acromegaly

The major difference between gigantism and acromegaly is the age at which an individual starts developing excessive growth hormones in their body.

Gigantism

In gigantism, the development of excessive growth hormone happens in childhood or adolescence when the growth plates of the bones are still open. Due to this reason, the individual will develop excessive height.

Acromegaly

The occurrence of acromegaly is seen when an individual is an adult and the growth plates of their bones are already closed. In this case, the patient will not experience excessive height but only enlarged hands, feet, and face.

Causes of Gigantism and Acromegaly

Both gigantism and acromegaly are caused by an overproduction of growth hormones. This condition is often triggered by a benign tumor of the pituitary gland. Learning about the common causes allows one to determine the difference between acromegaly and gigantism.

Causes of Gigantism

An overproduction of growth hormone is the reason for gigantism. The development of this condition may be linked to excessive amounts of the hormone produced before the growth plates close. Gigantism causes issues with the pituitary gland.

Pituitary Tumors: Development of benign tumors increasing the amount of growth hormones

Genetic Disorders: Rare conditions leading to hormone imbalance

Endocrine Dysfunction: Disturbances of hormonal functions require evaluation by an expert endocrinologist for accurate diagnosis and treatment.

These factors lead to rapid and abnormal growth in height and body size.

Causes of Acromegaly

Excessive production of growth hormones that leads to acromegaly takes place during adulthood. In other words, the condition is diagnosed if hormone overproduction occurs when the bones are fully developed. Thus, acromegaly is also referred to as a growth hormone disorder.

Pituitary Tumors: Most frequently found causes for acromegaly

Other Tumors: Rare non-pituitary reasons for hormonal imbalances

Endocrine Disorder: Uncontrolled hormone production

Learning about the causes allows diagnosing and treating acromegaly effectively.

Gigantism and Acromegaly Symptom

The symptoms of these two diseases vary despite both having an overproduction of growth hormone. Understanding these symptoms is crucial for differentiating between gigantism and acromegaly.

Gigantism Symptoms

• Fast growth of height
• Big hands and feet
• Late sexual development
• Painful joints and muscles

Acromegaly Symptoms

• Increased size of hands, feet, and facial structures
• Coarse skin and face structure
• Feeling tired and frequent headaches
• Painful joints and enlarged organs

The symptoms of acromegaly may be gradual, whereas the symptoms of gigantism happen quickly.

Gigantism and Acromegaly Diagnosis

The following methods can be used for the diagnosis of gigantism and acromegaly:

• Growth hormone and insulin-like growth factor-I levels test by blood sampling
• Pituitary tumor screening using an MRI scan
• Insulin hypoglycemia test

Precise diagnosis is necessary to determine the best course of treatment.

Gigantism Treatment Options

Surgery: Pituitary gland tumors are surgically removed to prevent excessive production of growth hormones. Surgery early in life promotes normalization of growth and prevents complications.

Medication: Drugs are administered to control excessive growth hormone levels. They work effectively in managing symptoms.

Radiation: In the case of resistance to surgery, radiation therapy is recommended. Radiation therapy slowly shrinks the tumor to ensure control of hormone levels.

Acmroegaly Treatment Methods

Surgery: The surgical procedure involves removing the tumors from the patient to control excessive production of hormones. It relieves symptoms such as headaches and vision problems.

Medication: Drug therapy controls hormone levels after surgery is ineffective. It works effectively in controlling symptoms.

Radiation: It is employed in the treatment of patients who do not respond to any other form of treatment. Radiation therapy slowly reduces the size of the tumor.

Follow-Ups: Follow-up procedures are critical for the management of the condition. They ensure hormone levels remain normal.

Complications of Untreated Conditions

If left untreated, both gigantism and acromegaly can lead to serious health issues:

• Cardiovascular disease
• Diabetes and insulin resistance
• Joint and bone problems
• Organ enlargement

This is why understanding the difference between gigantism and acromegaly and seeking early treatment is essential.

When to Consult an Expert

If you observe strange growth patterns, facial alterations, or any other signs associated with the disturbance of hormones, then consulting a specialist is highly recommended. Early diagnosis can facilitate better management of such conditions.

Conclusion

Gigantism vs. Acromegaly: The primary distinction between these two diseases is the age of onset due to growth hormone disorders, which is childhood and adulthood, respectively. Although these illnesses are similar in many ways, their physical impacts vary substantially.

The identification of acromegaly symptoms, knowledge about the causes of gigantism, and recognizing the signs of pituitary tumors can help detect these issues at an early stage and enable patients to deal with them more effectively. Proper treatment of acromegaly can be attained by visiting a specialized doctor.

In case of any unusual growth pattern or symptoms associated with hormonal imbalance, it is advised to consult a professional specialist. Schedule an appointment with Dr. Zaar, a prominent endocrinologist in Lahore, to receive a precise diagnosis and adequate therapy.
