Why Does the Aging Process Differ From Person to Person?
The aging process does not progress at the same speed or in the same way for everyone. Two individuals of the same age may show significant differences in physical resilience, energy levels, and overall health. This variation is primarily influenced by genetic factors, hormonal balance, stress levels, lifestyle habits, and environmental influences. The longevity approach recognizes these differences and does not treat aging as a uniform process.
At Ebru Ünal, MD’s clinic in Istanbul, Turkey, the Hertoghe Vitality approach is based on the understanding that the aging process is shaped by individual physiological dynamics, offering a personalized perspective on healthy aging.
According to the longevity perspective, the rate of aging is influenced by hormonal balance, metabolic health, and lifestyle factors. Chronic stress, poor sleep, and hormonal imbalances may accelerate aging, while balanced habits support healthier aging. At Ebru Ünal, MD’s clinic in Istanbul, aging is evaluated holistically and managed through personalized care, positioning Istanbul, Turkey as a center for medical wellness and longevity care for international patients.

Why do some people age more slowly than others?
