What causes hypothalamic obesity in a six-year-old child?

Question

Hello doctor,

My neighbor’s daughter is six and a half years old and looks very obese, and is taking a lot of medications at this age. I got to know that the child is affected by hypothalamic obesity.

I wanted to know in detail about the disease. Can you please explain? Also, my kid usually plays along with that child, and I am afraid that it could affect my kid as well.

Is that possible?

Hello,

Welcome to icliniq.com.

I understand your concern.

The hypothalamus is the part of the brain that regulates body weight, hunger, thirst, temperature, and hormones. When there is an injury or damage to this area, often due to brain surgery, trauma, tumors, infections, or genetic disorders, the normal signals for hunger and satiety can be impaired, leading to excessive, uncontrollable weight gain.

The condition is not contagious. The cause of hypothalamic obesity is damage or dysfunction in the hypothalamus, after surgical removal of a hypothalamic tumor, craniopharyngioma- a common benign brain tumor in children, genetic mutations (such as Prader-Willi syndrome), traumatic brain injuries, and radiation therapy.

When the hypothalamus cannot regulate energy balance, patients experience hyperphagia or intense hunger, which leads to rapid and often severe weight gain. Parents should be aware of sudden and unexplained weight gain that does not improve with diet or physical activity.

Children with hypothalamic obesity might display constant hunger and struggle with self-control around food, as the usual feeling of fullness is not properly signaled to their brains. Other symptoms may include low energy, sleep disturbances, behavioral changes, and hormonal imbalances.

Preventing hypothalamic obesity is challenging because it is a secondary condition resulting from another medical issue. Careful monitoring by endocrinologists and neurologists can help. Medications to regulate appetite or metabolism, and hormone therapy if other hormonal imbalances are present. Behavioral therapies, nutritional guidance, and regular physical activity can provide some support.

If you have further questions, please do not hesitate to reach out. Wishing good health to your family and your neighbor’s child. Get well soon.

I hope this helps.
