I have had several symptoms for years. Primarily severe fatigue, concentration difficulty, brain fog, speech difficulties, and weight gain. 6 months ago I was diagnosed with low vitamin d, low t, and sleep apnea(mild to moderate). I have had treatment for all of these and never noticed the first bit of improvement. I went to an internal med specialist recently and had lower testosterone than before the first treatment. Very low lh levels. Tsh was 2.8, t4 was 6.9, and anti thyroglobulin was 50. Iron was 204 and bilirubin 1.4. My questions are can low t and low lh cause these problems? Is my thyroid normal? And why would my testosterone drop to lower than before treatment(316 to 280)? 24 year old male
