- addison’s disease- Inadequate hormone production by the adrenal cortex
- cushing’s syndrome- Same as addison’s disease and results in distribution
- diabetes mellitus- Caused by inadequate insulin production
- hyperparathyroidism- Caused by excessive parathormone that results in an increased calcium blood levels
- hypoparathyroidism- Caused by inadequate parathormone that results in decreased calcium blood levels
- acromegaly- Enlargement of extremities
- diabetes- the body doesn’t properly process glucose
- hyperthyroidism- nervousness, increased HR, weight loss and irritability
- hypothyroidism- obesity, lethargy, decreased HR, thinning of hair
