I am 23 years old male and I would like to ask you for some help about my problem. A couple years ago I started getting tired when I do some physical activity. Unfortunately, this fatigue escalated as time passed by. Today I get really exhausted by doing normal stuff like climbing stairs, riding a bike or slow running, which is absolutely not normal, because I am an athlete in perfect physical shape. I feel the fatigue only when I do any physical activity and the feeling is like my body cannot supply my cells with enough energy or oxygen. My pulse is increasing very fast and I just get tired too quickly. At first, I thought that my hemoglobin levels are low, but they are just fine.
I did a lot of medicine tests. I started with complete blood test, minerals, hormones, liver enzymes (ALT, AST, ALP, GGT), heart holter monitoring, etc. Everything is perfect. I am completely healthy. My thyroid gland is fine too. I don’t have Hashimoto.
Recently I did another blood test which showed the following results, which are not normal:
Iron (Fe) – 40.6 (normal range: 11.6 – 31.3 μmol/l)
SHBG – 83.52 (normal range: 14.5 – 48.4 nmol/l) – That is almost twice as the highest normal range
Free testosterone - 0.49 (normal range: 0.204 - 0.657 nmol/l)
Total testosterone – 40.22 (normal range: 7.6 – 31 nmol/l)
Total bilirubin - 23.1 (normal range: 3.4 - 21 μmol/l)
Direct bilirubin - 8.5 (normal range: 0 - 8.6 μmol/l)
Glucose on empty stomach – 6.1 (normal range: 3.5 – 6.1 mmol/l)
My glucose levels on empty stomach are high, but I don’t have diabetes. I did an oral OGTT (drinking 75 glucose) and everything is fine. The test showed that my glucose and insulin levels are fine. Glycated hemoglobin is okay too – 5.3% (normal range: 4 – 6 %).
I eat well, I am in pretty good physical shape, I don’t have fat, I have no stress issues, I have no depression. If the fatigue is based on stress, I just don’t know where this stress is coming from.
So, my question is, do you think that my elevated levels of iron, SHBG and testosterone can cause this extreme fatigue or the problem is somewhere else? And if yes, what do you suggest me to do about it?
If you need any other information, I will provide it. The doctors have different opinions about my condition, that’s why I am searching for different opinions here, because I know that in this forum there are people with exceptional knowledge. And yes, as many of you already know, some doctors tell me that my blood tests are completely fine, even though I don’t feel well.
I really appreciate you taking the time to read about my problem and give your suggestions how to deal with it. Thank you to all of you!
