Can Tirzepatide help manage weight after a brain injury at 16?

Question

Hello doctor,

Can Mounjaro help manage weight gain from a brain injury? My daughter is 16 and has gained almost 48 pounds in 11 months, and nothing is working. She had a craniopharyngioma removed last year, and since then, her hypothalamus has not been functioning properly.

The endocrinologist confirmed hypothalamic obesity and said her leptin signaling is basically broken. She feels hungry literally all the time, even right after a full meal. We tried strict calorie restriction with a dietitian, but she cried from hunger constantly and still gained weight.

Her fasting insulin is 128, and she has early signs of fatty liver on ultrasound. Her pediatric endocrinologist mentioned Tirzepatide (Mounjaro) but seemed hesitant because of her age.

Are there any clinical trials or protocols using Mounjaro specifically for hypothalamic obesity in adolescents, and what are the real risks at her age?

Please advise.

Thank you.

Hello,

Welcome to icliniq.com.

There have been case reports of successful treatment of hypothalamic obesity with Tirzepatide (Mounjaro), including in a 21-year-old male patient. Hypothalamic obesity typically occurs due to damage to the hypothalamus, most commonly from tumors such as craniopharyngioma or following surgical treatment in that region.

This damage can disrupt normal appetite regulation, leading to hyperphagia (an uncontrollable increase in hunger) and a reduction in energy expenditure, both of which contribute to rapid and significant weight gain that is often difficult to control with conventional dietary measures alone.

Tirzepatide commonly has gastrointestinal side effects such as nausea, vomiting, diarrhea, constipation, and abdominal pain. Other potential complications include pancreatitis, gallstones, and kidney injury. These complications are not age-specific and can occur at any age, including in adolescents such as your daughter, who is already 16 years old.

You can find several case reports online regarding Tirzepatide use in hypothalamic obesity. Ultimately, the decision to use this medication is entirely yours. These complications do not occur in all patients, but they are potential risks that must be considered.

I hope this helps.

Please feel free to ask any further questions if needed. I will be happy to assist you.

Kind regards.
