### Patient: Doctor, I have been experiencing weight gain, long menstrual periods, nosebleeds, and nausea. What could be the problem?
### Doctor: Based on your symptoms, you could be suffering from a pituitary adenoma. This is a tumor that develops in the pituitary gland, which can cause hormonal imbalances leading to symptoms such as weight gain, menstrual irregularities, nosebleeds and nausea.
