I'm quite a sportive guy and I like every evening to go for a short bike trip around 60km. I like to push the bike a bit harder but sometimes something is happening. I became in one minute very very week, have a sensation of the need of biting something strong as my maxillary muscle feels contracting. I feel all the body very week and and is like I'm in different reality - I feel de-phased, some feeling as I would be drank, the vision is following the head with a short delay. A sensation as I need to stop biking and just go to sleep on the side of the road. What is strange is that sometimes I can pedal more than 100km at very dificult level and have no problem and sometimes after 20 km I drop dead like this.
I did all usual blood analysis, and they are normal, including the activity of the glands. My blood pressure doctor says is low and when on bike I compare the BPM with an older friend, in repaus I will have 100bpm and he is having always 20bpm less, same with my GF.
I forget to mention that I feel very nervous all the time and I can never take on weight. 1.89 with 73kg 29years.
Anyone have any ideea what could cause this fast droppings in energy?
