You are having sub-clinical hypothyroidism
- a small decrease in thyroid hormone production. Since your cholesterol levels are high you have to start on thyroxine tablets after consulting a doctor. Thyroid hormone treatment
will help to bring down your cholesterol levels.
The change in thyroid function and elevated urine ketones may be related to atkins diet as the diet is low in carbohydrate
Hope I have answered your query. If you have any further questions I will be happy to help
