Diagnostic Criteria
History and symptom
The common symptoms and signs of clinical hypothyroidism are listed in the table below. The appearance of symptoms depends on the degree of hypothyroidism severity: [1][2][3][4]

Laboratory Findings
Laboratory findings consistent with the diagnosis of euthyroid sick syndrome include

|---|---|
| Mild euthyroid sick syndrome |

| Moderate euthyroid sick syndrome |

Imaging Findings
Other Diagnostic Studies
In euthyroid sick syndrome the thyroid gland appears normal. Therefore, there is no role of thyroid uptake scan in euthyroid sick syndrome.
Treatment
Medical Therapy
Ill patients may have normal to low TSH depending on the spectrum of illness. Total T4 and T3 levels may be altered by binding protein abnormalities, and medications. Reverse T3 are generally increased signifying inhibition of normal Type 1 enzyme or reduced clearance of reverse T3. Measurement of free T4 and/or free T3 levels will be normal.
