Case analysis:

A 56 year old female, is experiencing chronic fatigue, headache, weight gain, constipation, and milky discharge from the breasts. The doctor prescribed higher doses of drugs,what are the possible reasons for the higher dose?

The standard drug treatment for hypothyroidism is a daily dose of a synthetic thyroid hormone called levothyroxine. This drug helps normalize blood levels of T4, TSH, and a third thyroid hormone called triidothyronine(T3).

Many prescription medications can interact with levothyroxine and either increase or decrease its potency. (Be sure your doctor knows all medications you are currently taking.) Large amounts of dietary fiber can also interfere with levothyroxine treatment. People who eat high-fiber diets.

These hormones can also alter the actions of other hormones and drugs.

thyroid-stimulating hormone (TSH)test for antithyroid antibodies and check your cholesterol levels. Based on these test results, the doctor will decide whether to prescribe

  8. Hi Dia!

    The good point - you wrote the questions again!

    At least I know what you're talking about ;)

    The 'needs improvement' point - spacing & presentation

    I'm sure you read all the comments.
    Suggestions:
    - Spaces between each numbers
    - Boldface the questions and italized the answers
    - to give emphasiz to an item, you can still boldface it, even though it's already italized

    Good luck!
