Can brain tumors cause weight gain?

I've been gaining weight suddenly without changing my diet or activity. My friend recently told me that sometimes brain tumors can cause unexplained weight gain, and now I'm a bit concerned.

Yes, actually! If the tumor is in the pituitary gland or hypothalamus, it can mess up your hormones and metabolism, which can lead to sudden weight gain. It's wild how much the brain controls our weight.

Yes, specific types of brain tumors affecting the pituitary gland can cause sudden weight gain. Please do not ignore this if it is accompanied by vision changes or headaches. It is extremely important to consult a neurologist for a proper safety checkup.

At this age, my metabolism is already slow, but yes, certain brain tumors can cause severe weight gain by disrupting the body's fullness signals. If you are gaining weight without eating more, don't just blame your diet—get a medical opinion.

Since I manage high BP, I know how hormonal changes can impact weight. Tumors in specific brain regions can alter thyroid function or cortisol levels, leading to rapid weight changes. Regular health checkups and proper scanning are essential if you suspect this.

I didn't know this was possible. My friend has been gaining weight rapidly along with bad headaches, and we thought it was just stress. Should we be asking a doctor for an MRI, or are there other symptoms we should look out for?
