As your parents grow older, it's perfectly natural to be concerned about them. The roles often reverse, with you beginning to show your parents the same level of worry that your parents had for you when you were coming of age. The situation can be a bit more tremulous if your parent happens to live alone. They might seem to be perfectly okay and refrain from expressing their need for care.
If you have not been feeling well lately and are suffering from pain in your throat, unusual weight gain, mood swings, and pain in your joints, there is a good chance that you might have an issue with your thyroid. A visit to a medical clinic will help you determine what is going on with your body, and you might discover that your thyroid is not working as it should.
