Acromegaly is a rare disorder caused by excessive secretion of growth hormone. Excessive hormone secretion of the pituitary gland leads to the tumor. This tumor causes overgrowth in various organs of body, especially in the bone structure, especially in hands, feet and face. Acromegaly can affect the bones and heart negatively, as well as triggering many diseases. It is usually seen in middle-aged people, but is likely to occur in children. Acromegaly may cause effects such as menstrual irregularity. The main treatment of acromegaly is surgery, but medication and radiotherapy also support treatment. Patients’ lifespan may vary but late diagnosis may lead to a significant reduction in lifespan. Early diagnosis is very important for treatment success.

Acromegaly is a rare disease that causes the body tissues and hormones to grow faster than they should. Abnormal growths occur in the bone structure, especially in the hands and feet. In addition to this, abnormal growth in the eyebrows, nose, lips and tongue occurs. This disease can lead to severe joint pain, fatigue, sleep apnea, headache and impaired vision.
It can also cause irregularity of menstruation period in women and erectile dysfunction in men. Since it is a slowly progressing disease, it may not be noticed immediately. This can lead to a significant loss of time for the initial stage of treatment.
Acromegaly occurs when the pituitary gland produces excessive hormones that balance and regulate the physical development of the body. Most patients with acromegaly have a benign tumor that affects the pituitary gland. Although these tumors are common in many people, they may affect the person and cause them to catch this disease.
The growth of the pituitary gland may be the cause of environmental factors (air pollution, stress, radiation, etc.). In rare cases, a tumor in the lungs, pancreas, brain or other part of body may also cause acromegaly. Sometimes it passes through family, but most of time it is not hereditary. It is most common in middle-aged people, but might be seen at any age.
As the symptoms are usually slow, people may not realize the disease. If you notice one or more of these symptoms, necessarily go to a doctor.
Since acromegaly is a slowly progressing disease, it can take a long time to diagnose. The patient’s history is important for diagnosis. Blood-glucose tests, MRI (magnetic resonance imaging) and tomography (CT scan) may also be necessary for diagnosis of acromegaly.
The recommended treatment for acromegaly depends on symptoms you have. The aim is to reduce the growth hormone production to normal levels and to alleviate the effect of tumor on tissues. In the treatment of acromegaly, surgical intervention method has highest probability to achieve a definite solution. However, surgical operation may not be sufficient if the tumor is larger than expected. Then, radiotherapy, drug therapy or other methods are used.
The patient sleeps with general anesthesia. The surgeon makes a small incision under the nose or under the upper lip to reach the pituitary gland. Uses an endoscope to see the tumor. He then removes the tumor with the help of surgical instruments.
With the removal of the tumor from the body, the level of growth hormone decreases immediately as well as the pressure on the surrounding tissue. Usually the swelling will begin to descend within a few days and the face will get the normal appearance.
As with any surgical intervention, there are of course certain risks. There is a little chance of damaging the healthy parts of the pituitary gland during surgery yet, it is amongst the possibilities. It may also be possible that the fluid protecting the brain will leak out during the intervention. Meningitis is another rare risk. Ask your doctor about possible risks before going into surgery.
If there is no decrease in post-operative growth hormone level, drug treatment may be applied. If tumors are large, preoperative medication may be required to shrink them and reduce problems during general anesthesia.
These drugs are used to regulate hormone levels. However, it can rarely cause gastro-intestinal disorders or elevated liver enzymes.
Radiation is used to destroy large tumors or parts of the tumor after surgery or when the drugs alone are not effective. It may be effective in lowering growth hormone levels when combined with the drug.
Radiation is performed in sessions at intervals of 4 to 6 weeks. It may take about a year to get results from this treatment. Radiation may have a negative effect on fertility. It can rarely cause vision loss, brain damage and secondary tumors.
Some plants have therapeutic properties against metabolic diseases that acromegaly patients bear high risk to get. These are;
However, side effects may occur as a result of the interaction of some plants with some drugs. Thus, consult your doctor before using any plant.
Untreated acromegaly can cause serious health problems. These;
Acromegaly can also cause the accumulation of fluid in the heart, lung and various body tissues.
If acromegaly is not treated, it may trigger a number of metabolic diseases. These are;
Although the effects of acromegaly have similar characteristics in every individual, it affects women from different perspectives. The disease can cause menstrual cycle irregularity, excessive hairiness, and abnormal milk flow from the breast apart from the pregnancy or breast-feeding.
There is no definite information in the medical literature about how long acromegaly patients can survive. However, patients’ life expectancy decreases by approximately 10 years. The risk of diabetes and heart disease is higher, especially in severe patients. This may decrease the life quality and decrease the life expectancy.
Acromegaly can cause fatal consequences if left untreated. However, early diagnosis positively affects treatment success.
Gigantism is a disease caused by the non-cancerous tumor which is caused by the growth of the pituitary gland just like acromegaly. The only difference between acromegaly and gigantis is that gigantism is visible in children. The symptoms of gigantism are almost identical to those of acrogemaly.
In children with this disease, excessive height length and early and rapid growth are seen comparing to their peers. Puberty initiates later than their peers. Symptoms of the disease may not be immediately apparent. Especially for children from a family having tall members, it is even more difficult to detect the disease immediately.
Early diagnosis for children is very important to prevent irreversible overgrowth.
