Well, I'm just wondering what is the matter with dark shadows or circles under the eyes? They look fine. Maybe we've just inherited them?
At the time of her diagnosis, I remember the PM looking unwell - no surprise there. She carried on working.
Bags under the eyes tend to happen with age certainly.
However, as an aside, recently my GP told me, after a blood test, that I was 'overcompensated with thyroxine' for my hypothyroidism and that I needed to reduce my daily dose of levothyroxine. Since reducing my dose, I've noticed that the bags or slight swelling under my eyes has almost gone away. Just a thought. It's quite common for thyroid problems to be associated with diabetes. Weight loss as a result of changes in diet for diabetes might mean your GP wants to adjust your thyroxine medication.
