How can hypothalamic obesity be managed in a teenage girl?

Question

Hello doctor,

My 19‑year‑old daughter developed hypothalamic obesity after having a craniopharyngioma removed three years ago. She has gained over 80 pounds since the surgery. Her periods stopped completely about a year ago, and her endocrinologist believes it is related to the weight gain and hormonal issues. She now weighs 240 pounds and has developed insulin resistance with a hemoglobin A1c of 6.8%.

The Metformin is helping slightly, but she is still gaining weight despite eating very little. Her leptin levels are extremely high at 45 ng/mL, yet she is constantly hungry and cannot control her appetite. She has developed sleep apnea, and she now requires a CPAP machine. Her self‑esteem is very low, and she rarely leaves the house anymore.

We have tried multiple diets and even worked with a nutritionist, but nothing has been effective with this type of obesity. Is there any medication or treatment that can help with hypothalamic obesity in young women? She wants to lose weight before starting college next year.

Please help.

Hello,

Welcome to icliniq.com.

I read your query and understood your concern.

The hypothalamus is one of the centers for appetite and weight control. If there is a problem in its functions due to surgery or trauma, one is likely to develop obesity, known as hypothalamic obesity. The hypothalamus also controls thyroid function and hormones that regulate menstruation, growth, stress response, water balance, and blood pressure. Because of this, you may experience irregular or erratic periods.

I suggest, along with Metformin, which you are already taking, using GLP‑1 (glucagon‑like peptide‑1) receptor agonists (RAs). GLP‑1 receptor agonists are safe and can improve hypothalamic obesity while also maintaining glycemic control. You can consider Liraglutide, Exenatide, or Dulaglutide.

The probable causes are as follows:

Tumors (Craniopharyngioma, as you mentioned).
Surgery to the brain near the hypothalamus.
Trauma.
Radiation therapy.
The hypothalamus also controls thyroid function and hormones involved in menstruation, growth, stress control, water regulation, and blood pressure. Because of this, you may have irregular or erratic periods.
I suggest you undergo an MRI (magnetic resonance imaging) of the head or brain. I suggest you follow the below mentioned treatment plan:Metformin 500 mg twice daily.
GLP‑1 agonists: Semaglutide subcutaneously as a weekly dose or Liraglutide subcutaneously as a daily dose (avoid in patients with thyroid cancer or pancreatitis).
Hormone replacement therapy to address menstrual irregularities.
If medical therapy fails, bariatric surgery may be considered as a last option.

I also suggest you adopt some lifestyle modifications as below:

Diet control.
Yoga and meditation.
Learning new hobbies and participating in outdoor activities.

Kindly follow up if you have more doubts.

I hope this helps.

Thank you.
