Hello Doctor, I am a 27-year-old female and currently weigh 80 kg. I recently had a full health checkup. My reports show hypothyroidism with TSH 10.2 while T3 and T4 are normal. I have severe Vitamin D deficiency (3.34 ng/mL), low Vitamin B12 (185 pg/mL), and blood indices suggest iron deficiency anemia. I am experiencing extreme hair fall, fatigue, low energy, and weight gain. My HbA1c is 6.0% (prediabetic) though fasting glucose is 94 mg/dL. My lipid profile shows low HDL (33 mg/dL) with normal LDL and triglycerides. Liver function, kidney function, urine test, ESR, prolactin, FSH, LH, testosterone, and CA-125 are normal. I would like to know if this condition is treatable and reversible, and whether with proper treatment and lifestyle changes I can safely lose 20 kg from my current weight. I would appreciate your guidance on treatment for thyroid, deficiencies, hair fall, and weight loss. How much time it will take to lose weight and cure thyroid?
