Humankind symptoms and conditions

Hi, I have been taking lisinopril 2.5 mg for a little over a year now. I am 20 years old and had high blood pressure for my age so my doctor prescribed me to a low dose (2.5 mg) of lisnopril. I didn't think much of it at first because I figured my doctor had prescribed it and knew what was best for me, so I have been taking it over a year now.
The past couple days, I've started to think more about things and am wondering if the lisinopril has anything to do with it. I have definitely noticed that my hairline is receding faster and my hair, especially in the front of my head, is thinning. I have also gained weight over the past year and cannot seem to get any weight off. I never had these problems of losing hair or gaining weight before I started lisinopril.
My question is could the lisinopril, even with the low dose of 2.5 mg that I'm taking, actually cause these types of things to happen?
If anyone reading this could please reply to me and let me know, I would appreciate it so much because I am really worrying about this. Thanks.
