I am 19. How do I manage weight gain after brain surgery?

Question

Hello doctor,

I am a 19-year-old woman who had brain surgery two years ago to remove a tumor near my pituitary gland. Since then, I have gained 60 pounds despite eating the same diet and trying to exercise regularly. My appetite feels uncontrollable, especially at night, and I never feel full even after large meals. I also have irregular periods, feel tired all the time, and have trouble regulating my body temperature.

My endocrinologist mentioned that weight gain after brain surgery in this area is common but difficult to treat with a regular diet and exercise. I am frustrated because people think I am just overeating, but I feel like my body's hunger and fullness signals are completely broken since the surgery.

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand your concern.

Weight gain after surgery near the pituitary is often a direct result of hypothalamic disruption, which can significantly disturb the body’s regulation of hunger, satiety, metabolism, temperature, and the menstrual cycle. The hypothalamus acts as the body’s command center for these functions, and when affected by surgery, it can lead to changes that are largely beyond personal control. Standard recommendations like diet and exercise tend to be far less effective because the issue is biological rather than behavioral. Uncontrolled hunger and severely diminished satiety are classic features, compounded by hormonal fluctuations that affect energy levels and reproductive cycles, manifesting as fatigue and irregular periods.

It is important to recognize that hormone levels, especially cortisol, thyroid hormones, and reproductive hormones, may be out of balance and require ongoing monitoring and possibly medical intervention. In such cases, treatments might include hormonal therapies or medicines to address hunger and metabolic disturbances directly. This is a medically recognized condition, and blaming oneself for weight changes is inappropriate.

The solution often involves multidisciplinary care, including endocrinology, nutrition, and sometimes psychiatry, especially if food cravings and mood issues arise. With time and proper support, symptom management and improved quality of life are possible, but progress may be gradual.
