Detailed answer

Dark circles and under-eye bags are often associated with thyroid-related issues. Thyroid problems can lead to changes in the skin, including puffiness and discoloration around the eyes. Hypothyroidism, in particular, can cause fluid retention and slower blood circulation, resulting in under-eye bags and dark circles. If you are experiencing persistent under-eye bags and dark circles, it is advisable to consult with a healthcare professional to evaluate your thyroid function and determine the appropriate treatment.
