Am I missing something?Having low testosterone just means you're not producing as much testosterone as you used to. However, the testosterone you are producing might be releasing in your body's tissues (like fat cells) and turn into estrogen, or DHT.Dr. Mike suggests getting another test just to make sure there wasn't an error. You may also want to look at your free testosterone level and sex hormone-binding globulin (SHBG).I've been on thyroid medication for two years but I still have constipation and fatigue. Should I check reverse T3?Dr. Mike thinks you might want to consider looking into to T3. A test called reverse T3 may offer some insight to why some people with hypothyroid remain symptomatic even while taking medication.If you have a health question or concern, Dr. Mike encourages you to write him at askdrmikesmith@radiomd.com or call in, toll-free, to the LIVE radio show (1.844.305.7800) so he can provide you with support and helpful advice.
