However if Lactose intolerance/malabsorption to one, probably Lactose intolerance/malabsorption to another, like food and
other drugs. Many other conditions, including stomach
irritable bowel syndrome can have similar symptoms, as well as some foods and drugs.
So switching from Synthroid to Levoxyl may not solve a 100% of the problems, but it should help ease some, that is, if it is from Synthroid. Hey worth a try!
Hope this helps.
Thank you for your faith and confidence.
