High blood pressure and problems?

Blood pressure consists of two numbers, something like 120/80 for example. The top number is the pressure while the heart is contracting. The lower number is the pressure in your system while your heart is between beats, or refilling. The lower number is more usually the concern, and only starts to be a concern as it climbs above 90. You're unlikely to have a problem from hypertension at your age, but to set your mind at ease ask your doctor if he or she is concerned. Then do try to fix the lifestyle problems you mention, because yes, they can contribute to the problem. And you don't mention nicotine, but that can contribute as well. Check your blood pressure once in a while to make sure it isn't climbing over time, and try to relax.

First of all, you shouldn't worry. That makes everything worse. It is normal to have an elevated blood pressure reading when you are in the doctor's office. It makes us feel stressed. It's called "White Coat Syndrome." Blood pressure varies all through the day. If you are stressed it can spike up some, even if you have normal blood pressure. What you need to do is take better care of yourself and then you will feel less stressed, and you can handle what you do have. I imagine you normal blood pressure is in the 121 range for the top number. Try to stop worrying about that. You're young, healthy and fine. Stop the caffeine, drink a lot of water and eat a healthy diet. Lose the sodas and junk foods. If you are stressed and not sleeping, you need to do the things that will relieve the stress. Do deep breathing. Whatever you like to do most for exercise. If you don't like to exercise, then walk a lot. Yoga is good for relaxing. If you continue having panic attacks and are unusually stressed, talk to your doctor about medication. But your life will be much better if you can handle those things without medication.
