Grave's disease occurs due to hypersecretion of thyroxine from the thyroid gland. This patient will have a high metabolic rate. Thus their heart rate and blood pressure will be high. It increases the energy production by mitochondria thereby increasing the temperature. Due to increased metabolism they use up their reserve food material easily and this leads to weight loss.
