There is no simple way to grow taller in just a week but with diet, exercise and lifestyle changes, it is possible to grow taller. Growth hormones in the body can be stimulated to gain additional height in time, as noted by MDhealth.com.
In order to maximize potential height and add inches, getting plenty of rest, exercising or taking prescription growth hormone treatments are all available options to aid in adding to a person's stature. Eating regularly and providing the body with the proper nutrients is also essential for stimulating growth. Permanent height can be added through surgery, or temporary methods, such as "status shoes" that can discreetly add height are options.
