From the age of 4 months, Chahad began to ask for food constantly, causing his body to become obese quickly. 

The Indian baby girl was named Chahad Kumar by her parents, when she was born as normal as many other children, but 4 months after birth, Chahad suddenly gained weight rapidly and by 8 months old, her weight was up to 20kg, equal to the average weight of a 6-year-old baby. 

Worried about her daughter’s health, Chahad’s father took her to the hospital for a checkup. After several tests, the doctor said the baby had “Leptin deficiency”, a rare disease with only 51 similar patients worldwide.
