Check what

A

Hypothyroidism

Check serum TSH

Hypothyroidism causes decreased LDL turnover due to decreased expression of LDL receptors —> elevated circulating levels of total cholesterol and LDL

Decreased activity of lipoprotein lipase —> hypertriglyceridemia

[If untreated hypothyroidism and statin started —> statin myopathy, can cause worsening on hypothyroid myopathy]

258
Q

DKA caused by

A. Fatty acid breakdown in the liver
B. Glycogenolysis in the skeletal muscles
C. Impaired bicarbonate reabsorption in the Proximal renal tubules
D. Impaired urine acidification in the distal renal tubules
E. Increased renal excretion of ketoacids
F. Peripheral lipolysis due to decreased catecholamine levels

A

A. Fatty acid breakdown in the liver

Insulin deficiency —> increased lipolysis of peripheral fat stores due to high catecholamine levels

Fatty acids are delivery to the liver and broken down into ketones

Ketone accumulation responsible for clinical manifestations of DKA
