[|Human|] hi my son is 4 years old and he has JIA and Rheumatic fever and about 2 months ago he started having a really bad odor to him we tried deodorant thinking it was him sweating and nothing helped we spoke to 2 different doctors and they think its a metallic smell but don t know what could be causing it
[|AI|]  Hi, Welcome to the ChatDoctorBrief answer... it could buy hyperthyroidism or metabolic disorder. Detailed answer... Since sweating can occur normal when there is increased temperature outside and body responses by increasing sweating to balance the body temperature. But if there is particular odor, it can be disbalance of metabolism which can cause metallic odor. As thyroid hormones have crucial roles in controlling metabolism, and if there is hyperthyroidism it can cause sweating and anxiety. Other cause can be amino acid metabolic disorder. I would suggest that get thyroid function test, blood electrolytes , urine test to detect amino acid metabolites, and follow accordingly. Chat Doctor.
