- Myxedema
- Slowed neuro functioning
Describe lipid metabolism with hypothyroidism
Increase in serum cholesterol and triglycerides that leads to atherosclerosis and coronary heart disease
What is myxedema?
Non-pitting boggy edema around the eyes, hands, and feed
What is the treatment for hypothyroism?
Synthetic thyroid hormone replacement therapy
Where are the inner adrenal glands located?
