Welcome to icliniq.com.
I read your query and saw the laboratory reports (attachments are hidden to protect the patient's identity). From what you have mentioned, it appears that your father has overcorrected his thyroid. He must take 100 mcg of Thyroxine only. Repeat his thyroid test after three months, only TSH (thyroid-stimulating hormone). His diabetes is not controlled. I would like to know his medication's name, dose, and times per day. He has some urine infection, likely because of high blood sugar. Once sugar gets controlled, the infection will resolve. Drink eight to ten glasses of water daily. Please do not change the dose of Thyroxine on your own, as it can be risky in patients with heart disease like your father.
I hope this helps.
