Possible Hypothyroidism

Hey everyone! I hope everyone is having a good night. I usual post on the adrenal forum because I suspected AF for the longest time. But after fully investigating and educating myself, I suspest a slow thyroid. Im hoping the experts here can help me. I know the symptoms of both AF and thyroid problems can be similar. I am a male and 22 years young. I started to really fall deep about a year ago.

My symptoms are as follows:

-Dry skin on face..well its more like oily and scaly. It flakes alot.
-dandruff that I never have been able to solve
-Very skinny and cant gain weight
-Always freezing cold including hands and feet. Sometimes my finger nails get purple underneath
-Shrunken testicles and never have any sex drive
-Losing muscle mass.
-Feels like I am losing bone mass. Probably from not digesting food.
-Constipation. Always slow at passing food. About 3 bowel movements a week
-Vision loss
-Low basal temp. 96.4 degrees


I have more symptoms too. The reason I believe this is thyroid problems that lead to AF is because of my history. About 10 years ago I was told by my dentist that my water had fluoride in it when I was a baby. They noticed this because I have white spots on my teeth. I also have very good tooth health which would explain the fluoride. But fluoride messes with the thyroid I heard. I never had any problems growing up other than, always had dry skin, always had dandruff, and I was always cold. Notice though, I wasnt as cold when I was younger and I had a lot more energy. I think my thyroid progressively depleted as I got older.

What do you guys think?
