Investigations[ edit ] Common investigations include blood urea nitrogen BUN and electrolytes, liver function tests , urinalysis ,  and thyroid function tests. Hematological investigations include hematocrit levels, which are usually raised in HG. If conservative dietary measures fail, more extensive treatment such as the use of antiemetic medications and intravenous rehydration may be required. If oral nutrition is insufficient, intravenous nutritional support may be needed. In addition, electrolyte levels should be monitored and supplemented; of particular concern are sodium and potassium. After IV rehydration is completed, patients typically begin to tolerate frequent small liquid or bland meals.
