Sultan Kösen, a Turkish citizen born in 1982, holds the official title of the tallest living person in the world according to the Guinness World Records. His exceptional height results from a pituitary adenoma, a benign tumor of the pituitary gland that causes excessive secretion of growth hormone. This case illustrates a specific medical phenomenon, gigantism, the understanding of which has evolved significantly over the past few decades.
Pituitary Adenoma and Gigantism: The Mechanism Behind Record Height
Gigantism is not simply a genetic trait of tall stature. It is an endocrine pathology related to an overproduction of growth hormone (GH), most often caused by a benign tumor of the pituitary gland. When this tumor appears before the closure of growth plates (during childhood or adolescence), long bones continue to grow well beyond usual limits.

In Sultan Kösen’s case, this tumor caused continuous growth into adulthood. The distinction from acromegaly, which occurs after the closure of the growth plates, is fundamental: in acromegaly, it is not the long bones that lengthen, but the extremities (hands, feet, jaw) that thicken.
The complications associated with gigantism go beyond mere size. Patients frequently experience joint pain, cardiovascular issues, and mobility difficulties. Sultan Kösen uses crutches to move around, which gives a concrete idea of the daily physical impact of this condition.

To better understand the journey of the tallest person in the world, one must consider both the medical aspect and the record itself.
Sultan Kösen: A Record Stabilized Through Medical Treatments
The most underestimated fact in Sultan Kösen’s journey can be summed up in one sentence: his height is now stabilized. Treatments targeting the pituitary adenoma have halted the progression of his growth.
Therapeutic options for this type of tumor include several complementary approaches:
- Transsphenoidal surgery, which aims to remove the tumor through the nasal passage without opening the skull
- Radiotherapy, used when surgery is not sufficient to completely eliminate the tumor
- Somatostatin analogs, medications that inhibit the secretion of growth hormone
Sultan Kösen received treatment at the University of Virginia in the United States. The stabilization of his height represents a medical success as well as a turning point in his daily life, as continued growth would have worsened joint and cardiovascular complications.
This therapeutic journey explains why Sultan Kösen’s height record has not progressed for several years. The Guinness World Records has measured and confirmed his height during successive checks, with each measurement confirming stabilization.
Robert Wadlow, Historical Height Record: Why It Remains Unmatched
The absolute record for human height ever recorded belongs to the American Robert Wadlow, from Alton (Illinois). His height far exceeded that of Sultan Kösen, making him the tallest person in documented history.
Robert Wadlow also suffered from pituitary hyperplasia. Born in 1918, he grew up at a time when modern endocrine treatments did not exist. His growth never stopped.
A Death Related to Gigantism Complications
Robert Wadlow died in 1940 from septicemia. The infection developed from a wound caused by a poorly fitted orthopedic brace on his leg. Untreated gigantism weakens tissues and reduces nerve sensitivity in the extremities, which explains why he did not detect the injury in time.
His case brutally illustrates what gigantism caused before access to specialized care. The comparison with Sultan Kösen, whose growth could be halted, shows the gap between two medical eras.
Extreme Gigantism: Why Cases Are Becoming Rare
Endocrinologists observe a clear trend: cases of extreme gigantism are declining in countries with developed healthcare systems. Medical imaging (brain MRI) allows for early detection of a pituitary adenoma, often before growth exceeds pathological thresholds.
Early screening radically changes the prognosis. A child whose growth curve deviates abnormally undergoes hormonal examinations. If an adenoma is identified, treatment (surgical or medical) occurs before height reaches extreme values.
This means that records like those of Sultan Kösen or Robert Wadlow are becoming less likely to recur in regions where access to endocrine care is assured. New cases of extreme height primarily come from areas where diagnosis remains delayed.
Measurement and Certification by Guinness World Records
The Guinness World Records applies a strict protocol to validate a height record. The measurement is done standing, feet flat, by an independent doctor, and must be reproducible. This rigor allows for distinguishing verified records from undocumented claims.
- The measurement must be taken in a vertical position, without shoes or headgear
- A certified doctor supervises the operation and signs the official document
- Multiple measurements spaced over time confirm the stability or progression of height
Sultan Kösen has been measured several times according to this protocol, which gives his record a reliability that older historical cases do not always have.
The difference between the “tallest living” and the “tallest in history” rests on this requirement for documentation. Some cases reported in ancient sources remain contested due to a lack of measurements conforming to current scientific criteria. Robert Wadlow’s record, on the other hand, benefits from photographs and medical records detailed enough to be considered reliable.
Gigantism remains a rare pathology, and each documented case enriches the medical understanding of growth hormone. Sultan Kösen’s record, frozen by the treatment of his tumor, could hold for a long time, precisely because modern medicine now prevents most patients from reaching such heights.
