1

Patho of Hypothyroidism

-TH production decreases

-Thyroid gland enlarges in attempt to produce more hormone

-hypothyroid state leads to myxedema

2

myxedema

swelling of the skin and underlying tissues giving a waxy consistency, typical of patients with underactive thyroid glands.

3

Primary etiology of Hypothyroidism

-defects in gland (congenital), loss of thyroid tissue, antithyroid meds, thyroiditis, endemic iodine deficiency

4

Secondary etiology of hypothyroidism

-pituitary TSH deficiency or peripheral resistance to TH

-medications can cause

-common in women 30-60 yrs

5

Risk factors for hypothyroidism

-women older than 50

-relatives with autoimmune disorders

-hx of thyroid surgery

-radiation of neck

-iodine deficiency

-hashimoto thyroiditis

6

Hashimoto Thyroiditis

-common cause of goiter and primary hypothyroidism

-Autoimmune disorder

7

Hashimotos Clinical Manifestations

-fatigue and sluggishness
-weight gain
-difficulty swallowing
-pale, dry skin
-puffy face
-constipation
-depression
-slowed HR
-feeling cold
-jt and muscle pain
-difficulty getting pregnant
-irregular or heavy menstruation

8

Hypothyroidism Clinical Manifestations

-slow onset
-goiter
-fluid retention and edema
-decreased appetite, weight gain
-constipation
-dry skin
-dyspnea
-pallor

(Levothyroxine)

12

Hypothyroid Health Hx

-onset, severity of symptoms

-diet, use of iodized salt

-pituitary dz

-tx of hyperthyroidism

13

Hypothyroid Physical Assessment

-muscle strength, deep tendon reflexes

-VS, Cardio, integument

-thyroid gland, weight

14

Hypothyroid Planning

-pulse and BP
-arrhythmias controlled
-skin remains intact, warm, dry
-free of edema
-activities resumed with normal HR
-elimination pattern returns to normal

15

Hypothyroidism Implementation

-Monitor Cardiac output
-prevent constipation
-encourage fluid intake of 2000mL/day
-high fiber
-increase activity
-maintain skin integrity
