  2. Oral glucose tolerance test. To confirm the diagnosis, your doctor will order an oral glucose tolerance test.

What is screening test for acromegaly?

Acromegaly is a rare condition where the body produces too much growth hormone, causing body tissues and bones to grow more quickly. Over time, this leads to abnormally large hands and feet, and a wide range of other symptoms. Acromegaly is usually diagnosed in adults aged 30 to 50, but it can affect people of any age.

How is acromegaly treated?

Purpose: Growth hormone (hGH) suppression by a glucose load is the classic screening test for acromegaly. In addition, the test may be used to monitor the progress of treatment.

What is the most common cause of acromegaly?

The goal of treatment is to restore the pituitary gland to normal function, producing normal levels of growth hormone. Treatment may include removal of the tumor, radiation therapy, and injection of growth hormone blocking drugs. Left untreated, acromegaly can lead to worsening diabetes mellitus and hypertension.

Is acromegaly an autoimmune disorder?

Is acromegaly painful?

In adults, a tumor is the most common cause of too much GH production: Pituitary tumors. Most acromegaly cases are caused by a noncancerous (benign) tumor (adenoma) of the pituitary gland. The tumor produces excessive amounts of growth hormone, causing many of the signs and symptoms of acromegaly.

How long can you live with acromegaly?

Conclusion: We found a high prevalence of thyroid autoimmunity in our patients with acromegaly as compared to the normal population. Thyroid autoimmunity seems to be an additional mechanism for the development of thyroid disorders in acromegaly.

What organs are affected by acromegaly?

Life expectancy may be reduced by approximately 10 years, especially when growth hormone levels are uncontrolled and diabetes and heart disease are present. Patients who are successfully treated for acromegaly and whose growth hormone and IGF-1 levels fall to normal generally have a normal life expectancy.

What happens if acromegaly goes untreated?

As acromegalic skeletal abnormalities are rather irreversible, apneic episodes may persist after normalization of hormonal levels. Aggressive therapy, including surgery, pharmacological treatment and, in some cases, pituitary irradiation, aiming at normalization of IGF-1 levels, is required for arthropathy management.

Is acromegaly a chronic condition?

Additional symptoms of acromegaly may include abnormal enlargement of the liver (hepatomegaly), spleen (splenomegaly), intestines and/or kidneys. The thyroid (goiter) and/or the adrenal glands may also become abnormally enlarged.

How can acromegaly be prevented?

Does acromegaly cause low testosterone?

Can pituitary tumors cause hair loss?

The results indicate that hair loss is indeed a problem experienced by many patients who undergo surgery for acromegaly. Of those included in the study, more than half of participants (54%) experienced some level of hair loss between 3 and 6 months following their procedure.

What is the most effective cure for acromegaly?

Hair loss done not usually occur. The most common side effect is loss of normal pituitary function. This may occur within a year or many years after treatment. One study reported that 50% of patients treated with conventional radiation developed deficiency of one or more pituitary hormones within 2 years of treatment.
