Hello, Good day. May i know what was your thyrxine dose before your current blood test? You have to take thyroxine everyday in the mornng before food and keep the tablet protected aay from light , sun and heat. Once your TSH levels normalize, there are chances that the cholesterol also can become normal. Hypothyroidism is often not cured, but can be effectively controlled by taking medicines. For toning your body, you need a supervised exercise program. Eat less carbohydrates and exetrcise daily. Get a personal trainer in a gym. He will help you to get the body toned Regards binu
