Let us look into the concept of acromegaly. It is a condition in which your body produces too much growth hormone (GH). GH is a hormone that regulates the body’s physical growth and is produced mostly in the pituitary gland. When this hormone is overproduced in adults, it causes bones, cartilage, bodily organs and other tissues to grow in size. Acromegaly symptoms include an increase in the size of the hands and feet. An expansion of the forehead, jaw and nose is also possible.
Other signs and symptoms include joint discomfort, thicker skin, a deeper voice, headaches and eyesight issues. Type 2 diabetes, sleeplessness and high blood pressure are all possible complications of the condition. Acromegaly is caused by an adenoma, a benign pituitary gland tumor that produces too much growth hormone. As these tumors grow larger, they create an over-abundance of growth hormones and squeeze the surrounding brain regions.
They may compress the optic nerves in rare circumstances. The treatment aims to lower GH production to normal levels, reversing or improving the signs and symptoms of acromegaly, relieve the pressure that the developing pituitary tumor imposes on the surrounding brain regions, and retain normal pituitary function.
Acromegaly can be defined as a hormonal condition that happens when the pituitary gland generates an excessive amount of STH/ growth hormone in maturity. Your bones develop in size when you have too much growth hormone. This causes gigantism in children, defined as an increase in height. In adulthood, however, there’s no variation in height. Instead, acromegaly refers to an increase in bone size restricted to the bones of your hands, foot and face.
The disease is not passed down from one’s parents. A tumor causes acromegaly in another body section only in rare cases. Growth hormone is measured when a person drinks a glucose solution or insulin-like growth factor I is measured in the blood. Following a diagnosis, diagnostic imaging of the pituitary gland is performed to see if an adenoma is present. When too much growth hormone is generated throughout childhood, it causes gigantism rather than acromegaly.
A tumor causes the overproduction of growth hormone that is linked with acromegaly.
The most frequent form of a tumor in the pituitary gland is a pituitary adenoma, a non-cancerous or benign tumor. The pituitary gland produces too much growth hormone (GH), promoting abnormal growth. Pituitary tumors are not passed down through the generations. They can arise due to a tiny genetic mutation in one gland cell. This cell will multiply over time and produce an adenoma, a type of tumor. Adenomas are not cancerous since they do not spread to other body regions, but their size and placement might create difficulties. Cancer can exert strain on adjacent brain tissue as it develops. Because the skull is a confined region, this expansion can induce headaches and visual issues by crowding the remaining tissue. Because of the tumor’s location, it may potentially impact the synthesis of other hormones. Due to the hormone involved, the effect might differ between men and women. It may influence a woman’s menstrual cycle, while some males may have impotence.
A tumor in another part of the body, such as the lungs, adrenal glands or pancreas, might cause GH overproduction, leading to acromegaly symptoms.
The tumors themselves may release growth hormone or the pituitary gland may be reacting to a signal by producing GH. Some hypothalamic tumors, for example, may create growth hormone-releasing hormone (GHRH), which instructs the body to make GH.
Increased growth hormone production outside the pituitary gland, such as from neuroendocrine tumors like small cell lung cancer or carcinoid tumors can cause acromegaly.
Enlarged hands and feet are a common symptom of acromegaly. You may notice for example, that you can no longer put on rings that used to fit and that your shoe size has gradually grown. Acromegaly can also lead to progressive changes in the form of your face, such as a projecting lower jaw and brow bone, an expanded nose, thickening lips and wider tooth spacing. Early indications of acromegaly may not be seen for years due to the gradual progression of the disease. However, individuals might sometimes see bodily changes when comparing old and new images.
Acromegaly signs and symptoms vary from person to person; however, they might include any of the following:
Because the symptoms of acromegaly arise gradually, a diagnosis might take months, if not years. However, acromegaly can be detected early if the hands and feet swell and expand to a bigger size. In addition, people usually become aware of it when their gloves or shoes no longer fit.
A range of tests can be used to confirm acromegaly.
For example, an oral glucose tolerance test (OGTT) can provide a more precise GH level readout.
Before consuming concentrated glucose solution and delivering a blood sample, the patient must fast overnight. Normally, consuming glucose causes a drop in hormone levels. However, the hormone levels in a person with acromegaly would remain high because the body produces too much GH.
Treatment for acromegaly differs from person to person. The location and size of your tumor, the intensity of your symptoms and your age and overall health will all influence your treatment approach.
Treatment options for lowering GH and IGF-1 levels often involve surgery or radiation to remove or shrink the tumor causing your symptoms, as well as medicines to assist in restoring your hormone levels. In addition, if you’re dealing with acromegaly-related health issues, your doctor may suggest additional therapies to assist you in managing your symptoms.
