Why have i been tired,light-headed, and nauseated for so long?


I'm a healthy, active, 15-year-old boy (5'9", 132 pounds) that is experiencing something that really frustrates me, and I'm curious for answers as to what may be causing it.

About three weeks ago, I was sick (it is just a normal sickness, tiredness, sore throat, mild coughing) but what was the most outstanding symptom was my tiredness. I am a high-school wrestler, and I am extremely fit, but every time I would try to practice, my muscles would become fatigued quickly, and I was extremely tired and nauseated to the point where I could barely run. About a week had passed after that, and I would have sore throats in the morning that would require that I drink water immediately upon waking up. The sore throat would subside throughout the day but come back the next morning. As of today (February 7), I have been tired, every day, for the past three weeks (but no sore throat for about 1 week). I get tired fast during practice, and I have trouble focusing. I experience a lot of light-headedness when standing or doing anything physical really. I used to be able to run for miles without much fatigue at all, but now I can't even do a slow jog for gym class without feeling very heavy and wanting to quit. I don't feel like I want to do ANYTHING that requires much physical exertion. This frustrates me because I'm a very active person normally and I love getting work done, staying motivated, being physically capable of many things. I've collected some stats that were recorded today if they may help answer my questions: 96.8 degrees F temperature. 98 over 57 resting heart rate. Although this sounds like someone who is very sleep deprived, I can guarantee you that I get plenty of sleep.

Thank you for reading, because I can't wait to get back into a normal, active (and non-tired), life.

Hello and welcome to MedHelp's forums. Thanks for your question and we are sorry for the delay of a response.  How are you feeling now?  Sometimes after recovering from a virus, it can take a bit of time to bounce back. This could be the case for you.  If you are still suffering fatigue, weakness, dizziness and occasional nausea, please speak to your doctor.  As you are very active, sometimes there can be an issue with dehydration and taking in enough calories to support your activity. Dehydration can sometimes happen because of a few things and if you had a fever when sick, this is fairly common.  Here's info on the symptoms of dehydration. https://www.webmd.com/a-to-z-guides/dehydration-adults#1.

If you are not eating enough, you will also have some of these symptoms.  Athletes need a minimum of 2,000 calories a day and often more especially a young man during the growing years.  Here's some other tips on eating for athletes. https://www.webmd.com/fitness-exercise/features/nutrition-tips-athletes#1.

Hopefully you are fully recovered by now but if not, please see your doctor.
