Bone size increases when you have an excessive amount of growth hormone. In childhood, this leads to raised height and is named gigantism. However, in adulthood, a change in height does not occur. Instead, the increase in the bone size of hands, feet, and face occurs and is named acromegalia.
The condition generally takes an extended time to acknowledge as acromegalia is rare, and also, the physical changes occur slowly over a few years. There will be an adverse effect of Untreated, high levels of growth hormone in different parts of the body, in addition to your bones. This may result in serious — sometimes even grave — health issues. However, treatment can cut back your risk of complications and considerably improve your symptoms, including the enlargement of your features.
Symptoms
Gradual changes might occur in face structure like a projected jawbone and brow bone, an enlarged nose, thickening of lips, wider spacing between your teeth, etc., due to acromegaly.
Early signs might not be evident for years, as acromegaly progresses slowly. Sometimes, individuals notice the physical changes solely by scrutinising recent photos with newer ones.
The signs and symptoms of acromegaly tend to vary from one person to another and might embody any of the following:
- Feet and hands Enlargement
- Facial structure changes such as Enlarged facial bones, lips, nose, and tongue
- Weakness of muscles and joints
- Fatigue
- restricted joint mobility and pain
- Deep or husky voice because of enlarged vocal cords
- sinuses
- thickened and oily skin
- Excessive sweating and body odour
- Small outgrowths of skin tissue such as skin tags
- Irregular Menstrual cycle in girls
- Erectile dysfunction in men
- Severe snoring because of obstruction of the upper airway
- Eye problems such as Vision issues
- Headaches, which can be persistent or severe
- Low or no sex drive, low libido
Causes-
Over an extended period of time, due to the excess production of growth hormones by the pituitary gland, the condition called acromegaly occurs.
The pituitary is a tiny gland at the base of your brain located behind the bridge of your nose. It is responsible for the production of growth hormones and a variety of different hormones in the body. GH plays a critical role in managing your physical growth.
When the Growth hormones are released into your blood by the pituitary gland, it triggers your liver to supply a hormone known as insulin-like growth factor-1 (IGF-1) — generally known as insulin-like growth factor-I, or IGF-I. IGF-1. It is what causes your bones and alternative tissues to grow. An excessive amount of IGF-1 is due to an excessive amount of GH, which might cause acromegalia signs, symptoms, and complications.
A tumour is the most common reason for an excessive amount of GH production in adults.
Treatment-
The treatment for acromegaly varies from person to person. The treatment plan will rely upon the situation and size of your tumour, the severity of symptoms, and the age and overall health of the individual.
To lower growth hormone levels, treatment choices are generally surgery or radiation to get rid of or cut back the size of the tumour that’s inflicting your symptoms and drugs to assist in normalising your hormone levels.
If a person is facing health issues due to acromegaly, the doctor could recommend further treatments to assist in managing the complications.

Surgery
In this procedure, the Doctors, with the help of a technique known as transsphenoidal surgery, will remove most pituitary tumours. Throughout this procedure, the operating surgeon works through the nose to remove the tumour from the pituitary gland. The doctor will suggest another sort of surgery to get rid of the tumour. If the tumour inflicting symptoms is not situated in your pituitary,
In several cases — particularly if your tumour is small — removal of the tumour returns your GH levels to normal. If the tumour was putting pressure on the tissues around your pituitary, removing the tumour conjointly helps relieve headaches and vision changes.
In some cases, there is a possibility that the operating surgeon might not be ready to remove the whole tumour. If this is the case, the patient will still have elevated growth hormone levels after surgery. However, The doctor could suggest another surgery, medications, or radiation treatments.
Medicines used for treatment-
The doctor could suggest one among the subsequent medications — or a mixture of medicines — to assist the hormone levels to come to normal:
Drugs that cut back growth hormone production, e.g. somatostatin analogues. In the body, a brain secretion known as somatostatin works against GH production. The medication octreotide and lanreotide are artificial versions of somatostatin. Taking one among these medications signals the pituitary to supply less GH and will even cut back the size of a pituitary tumour. Typically, these medications are injected into the muscles (gluteal muscles) once a month.
-
Radiation
If the doctor fails to remove the complete tumour by surgery, they might suggest radiation treatment. Radiation slowly reduces GH levels by destroying any lingering tumour cells. It will take years for this treatment to improve acromegaly symptoms perceptibly.
Not just GH, but radiation treatment typically lowers alternative pituitary hormones as well. By receiving radiation treatment, in order to ensure that the pituitary gland is functioning properly and to examine hormone levels, one will probably need regular follow-up visits with the doctor. This follow-up care could last for the entire life.
Types of radiotherapy include conventional radiation therapy and stereotactic radiosurgery.
Conclusion-
Acromegaly is a Greek word meaning enlargement of the extremities. It’s a hormonal disorder that results once the pituitary body produces excessive growth hormone (GH) in adulthood after the attainment of puberty. The incidence of acromegaly is about 3-4 cases per million population per annum. The illness largely affects middle-aged adults, and the mean age of diagnosis is 40-45 years. It may end up in serious illness and premature death. In other words, acromegaly is caused by prolonged overproduction of growth hormones by the pituitary adenoma or benign growth. Acromegaly is caused by prolonged overproduction of GH by the pituitary.
