What are the differential diagnosis of hyperthyroidism?

Hello,

Welcome to icliniq.com.

I read your query and understand your concern.

You have mentioned pallor on physical examination. Hence investigation with CBC (complete blood count) and peripheral smear examination has to be done. If the Hemoglobin level is low and macroovalocytes are seen then vitamin B12 deficiency has to be ruled out by serum B12 estimation. Second other causes for peripheral neuropathy has to be ruled out if B12 deficiency is not present. These other causes include diabetic neuropathy, calcium deficiency, potassium-like electrolyte deficiency, and hypothyroidism also have to be ruled out by serum TSH, and T4 estimation. History regarding liver disease, kidney disease, and alcohol has to be ruled out. If on physical examination radiculopathy like nerve compression is suspected then CT (computed tomography) spine investigation might be needed. According to the cause. further specific treatment can be given. If vitamin deficiency is found then treat with vitamin tablets or injections. Consult your specialist doctor, discuss with him or her, and take the medicines with their consent. As far as primary diagnosis is concerned without physical examination it is difficult to reach one cause, but as pallor is present vitamin B12 deficiency seems most likely here.

Take care.Hope your concern is solved.

Regards.
