My thought was thyroid weakness as well. However, I spent nearly 6 months (last year) taking over 100MG of Iodine daily in the form of Lugol's solution. Absolutely no aid for constipation or basal body temp which is still too low; along with cold hands/feet. After working on strengthening the liver, I'm now thinking adrenal. I hate this self diagnosis stuff. I was not satisfied with my previous ND. I'm not comfortable with this weak economy to try another.
Thanks for your info regarding aloe ferox. I knew it had some differing properties with aloe vera. I thought it might be a stronger laxative than aloe vera. It seems to be in my experience.
I'm currently using magnesium hydroxide for constipation with occasional use of aloe ferox.
I have not given up on your suggestions of lifestyle change and diet. I just need extra help it seems.
