Final answer:
Symptoms like intolerance to cold, constipation, bradycardia, and brittle nails and hair match with hypothyroidism, whereas exophthalmus, intolerance to heat, diarrhea, and tachycardia are indicative of hyperthyroidism.
Step-by-step explanation:
Matching the signs and symptoms with the correct disease process is essential to understanding different medical conditions. Hypothyroidism and hyperthyroidism are two diseases with distinct but sometimes overlapping signs and symptoms. Intolerance to colds, constipation, bradycardia, and brittle nails and hair are symptoms commonly associated with hypothyroidism, a condition characterized by insufficient thyroid hormone production that slows metabolism. Exophthalmus, intolerance to heat, diarrhea, and tachycardia are typically found in individuals suffering from hyperthyroidism, where the thyroid gland is overactive, increasing metabolism. It's important to be aware that various illnesses might present similar symptoms, and proper medical evaluation is crucial for an appropriate diagnosis and treatment plan.
