Elisany, thought to be one of the tallest teenagers in the world, could be suffering from a rare disease that has caused her to tower over the rest of her peers, the Daily Mail reported.
But Elisany and her family are not sure exactly what that condition is because they can’t afford to see a doctor.
Although Elisany has not been diagnosed with any specific condition, an expert told the Daily Mail he believes she could be suffering from gigantism, which is caused by an excess of growth hormone during childhood.
"She might have the symptoms of the disease, which may be the headache, vision problems, and death of some other glands, like the thyroid, adrenals and the ovaries," the expert said. “It might cause serious implications for her health and even death."
The most common cause of too much growth hormone release is a benign tumor of the pituitary gland, according to the National Institutes of Health.
Due to her abnormal height, Elisany said she was forced to quit school because she became too tall to ride the bus.
"It's hard when I'm inside home," she told a local TV station in Brazil. "I get distracted and hit the wood in the ceiling with my head."
Elisany’s mother, Ana Maria Silva, said she just wants her daughter to be like the other girls.
"I want her to stop growing up," Silva said. "I know she feels weird and sometimes wants to be like them."
Elisany talks with her sister Talicia, 12, at her house in Braganca in the Brazilian Amazon state of Para August 29, 2010.
Even though the sisters are just two years apart, you can see the incredible difference in their height.
Although it depends on genetics, the average height of a 14-year-old girl is around 5-feet to 5-feet, 3-inches tall.
If Elisay does have gigantism and it is left untreated, some experts believe she could grow at the rate of six inches a year, which means she could be over 7 feet tall in no time.
Despite her condition, Elisany is looking forward to a bright future.
She dreams of being a famous fashion model, and according to several reports, she will make her runway debut at a bridal show in Belem, Brazil.
It’s hard enough to fit in as a teenager, but for 14-year-old Elisany Silva from Brazil, blending into the crowd is even tougher because she stands at a staggering 6-feet, 9-inches tall!
