Hello,
Please look into Postural Orthostatic Tachycardia Syndrome (POTS). It is a very unheard of nervous system disorder that prevents the body from being able to properly adjust to the pull of gravity. Therefore, symptoms arise, such as: rapid heart rate upon standing, low or high blood pressure, dizziness, fainting, fatigue, sweating, anxiety-like symptoms, headaches, shortness of breath, inability to exercise, digestion problems, etc. The symptoms are endless and vary person to person day to day. Very few doctors are familiar with this illness and often misdiagnose patients. It primarily targets young females.
Please feel free to contact me if you have any questions.
Best wishes,
Brandi
This doesn't sound like heart problems at all and on a side note, if this makes you feel any better, ALL babies are born with a heart murmur and most murmurs cause no problems. talk to your mother about the way you feel so she can help take care of the situation. take care and go enjoy your life! have fun!
Please discuss all unusual physical (and mental ) symptoms with your parents and thus with your doctor if they agree.
At the age of 14 I believe your body is still undergoing growth and development and the lung capacity may increase. Did your doctor recommend any physical exercises - I think young people who engage in regular physical exercise will develop stronger bodies and organs specifically from the exercise. Us old folks need to exercise too, I keep telling myself.
The food symptoms may be indigestion - and should also be discussed with your parents. They may suggest just using an antacid or some other help. Then too, it seems we each have different reactions to foods and some foods are very dangerous for some people (peanuts come to mind), and if we know of any food sensitivities then it would seem wise to stay away from such foods.
Please discuss with your parents.
