How to treat hypothalamic obesity in a 34-year-old woman?

Question

Hi doctor,

My 34-year-old wife has hypothalamic obesity that started after she had a craniopharyngioma removed three years ago. Since the brain surgery, she has gained 95 pounds, going from 140 to 235 pounds, and nothing seems to stop the weight gain, no matter what we try. Her endocrinologist says the damage is causing uncontrollable hunger and metabolic problems that regular diets cannot fix.

She is on hormone replacements, including Levothyroxine 125 mcg for thyroid, Hydrocortisone 20 mg for adrenal insufficiency, and Desmopressin for diabetes insipidus. She tried 2000 mg of Metformin daily and Phentermine, but neither helped with the hypothalamic obesity at all. Her leptin levels are extremely high at 78 ng/mL, and her insulin resistance is severe, with a fasting insulin of 45 µIU/mL.

The weight gain has caused sleep apnea requiring CPAP machines, high blood pressure, 165/98 mmHg, and prediabetes with an A1c at 6.2%. She is so depressed about her appearance, and we are trying to conceive, but her periods are irregular, coming every 45 to 60 days. Her gynecologist says obesity and hormone imbalances are preventing ovulation. She tried the GLP-1 agonist Liraglutide, but insurance will not cover it for hypothalamic obesity. Is there any way to manage this type of obesity? Can she safely get pregnant with all these complications?

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I understand your concern.

Yes, there are ways to manage hypothalamic obesity (HO), and pregnancy is possible, but it must be carefully planned. Management strategies:

Targeted medication: Seek Setmelanotide. It is FDA (Food and Drug Administration)-approved for certain genetic obesities affecting the same brain pathway damaged in HO. It is the most promising drug and may be tried off-label.
Optimize hormones: Work with a reproductive endocrinologist. Her irregular periods need addressing (possibly ovulation induction).

Pregnancy:

Requires pre-conception optimization: Blood pressure, blood sugar, and weight must be stabilized first.
Manage medications: Some drugs (like Setmelanotide) have no pregnancy data and must be stopped before conceiving.
High-risk pregnancy: She will need a maternal-fetal medicine specialist due to obesity, hypertension, diabetes insipidus, and adrenal insufficiency.

Action plan now is:

1. Specialist: Find an endocrinologist specializing in hypothalamic obesity.

2. Medication: Push for Setmelanotide or get a GLP-1 agonist.

3. Pre-conception counseling: See a reproductive endocrinologist soon to create a safe plan.

So, focus on finding a specialist for targeted HO treatment (Setmelanotide), then carefully plan pregnancy with a high-risk obstetrics team.

I hope this answers your query.

Revert in case of queries.
