An obese patient comes to the clinic complaining of swollen feet and ankles, fatigue, shortness of breath, and often feeling spaced out. She is a cashier in a grocery store, a job that requites her to stand all day. Outside of work, she engages in no physical activity. She confesses that, because of her weight, she finds even walking uncomfortable. Explain how the skeletal muscle pump might play a role in this patients signs and symptoms.

A 56-year-old woman named Cranberry complained during her yearly physical examination of tiredness and difficulty concentrating. She attributed these symptoms to stress at work. She had gained weight over the last year and despite warm weather, she felt chilled without a sweater. Family history was significant for hypothyroidism in her mother and older sister. On physical examination she had a pulse of 58 bpm and a blood pressure of 138/88 mm Hg. Examination of her neck disclosed a small thyroid gland with a palpable pyramidal lobe and a firm, bosselated texture. Serum taken at this time demonstrated a total T4 of 7.0 mcg/dL and a TSH of 22.0 mcIU/ml. In addition, antithyroglobulin antibodies were positive at 1:640 and antimicrosomal antibodies were positive at 1:5120. These results supported the clinical impression of hypothyroidism; also, the texture of her thyroid gland and a positive family history suggested an autoimmune etiological factor.
