Helo maam
Sorry to hear about your concern
Looks like she might have to change the dose of her medication depending upon her comorbidities and along with diet restrictions.
Next Steps
1. Diet changes
2. Eltroxin 75 or 88 depending on her symptoms
3. Some investigation required ( which can be helped by two way communication)
