I have big time constipation problem. I have fatty liver
Make sure you are euthyroid....
First, check TSH values (if it hasn't been tested recently). You will not be able to solve digestion issues / constipation if you are not in euthyroid state (normal TSH value).
If TSH value is in limits, I'd suggest drinking plenty of fluids. Added fiber diet with fruits and vegetables will help. If it doesn't you can try Ispaghula husk that is available over the counter. Taking it every day should be able to solve constipation issues.
Hope this helps. Let me know if you need clarifications.
