Sorry to hear about your daughter's problem. Her increased cholesterol
can be explained because of the Hashimoto's disease. Hashimoto's diseaase leads to hypothyroidism
, which is evident by her high TSH
levels and hypothyroidism leads to increase in cholesterol levels.
These levels will come down as her thyroid levels normalise. This has no relationship with consumption of food after the medicine.
Hoping for the best.
