A person with which of the following conditions tends to become overweight and has trouble with balance and posture due to lack of muscle tone in their limbs?

Down syndrome is associated with a range of physical and cognitive traits, and it is commonly recognized that individuals with Down syndrome may have lower muscle tone, also known as hypotonia. This reduced muscle tone can lead to difficulties with balance and posture, which can contribute to challenges in physical activities. Consequently, these difficulties can sometimes result in a tendency to become overweight, especially if physical activity levels are lower than recommended.

Individuals with Down syndrome often require support in physical fitness and muscular development to help mitigate these issues. The combination of hypotonia, balance challenges, and potential sedentary lifestyles can create barriers to maintaining a healthy weight. This understanding of the physical characteristics of Down syndrome clarifies why this condition is linked to the symptoms described in the question.
