This patient has hyperthyroidism as shown by her symptoms and laboratory results. Brittle nails are a symptom of hypothyroidism. The reduced metabolic rate in hypothyroidism affects the body's ability to produce and utilise various nutrients. Slower metabolism can lead to impaired circulation to the nail bed, limiting the delivery of vital nutrients. Furthermore, the thyroid hormones also play a role in regulating protein synthesis, including the production of keratin, a key structural protein found in nails.

This patient has hyperthyroidism as shown by her symptoms and laboratory results. Bradycardia is a symptom of hypothyroidism. The slow metabolic rate reduces heart rate. In addition, hypothyroidism may shift our body towards increased parasympathetic nervous system activity, which slows down the heart rate. By contrast, hyperthyroidism is more commonly associated with tachycardia.

This patient has hyperthyroidism as shown by her symptoms and laboratory results. Cold sensitivity is a symptom of hypothyroidism. When thyroid hormone levels are reduced, the metabolic rate decreases, resulting in reduced heat production by the body. The body may also have difficulty maintaining adequate peripheral blood flow, which can lead to cold extremities and an overall feeling of coldness. By contrast, hyperthyroidism is more commonly associated with heat intolerance.

This is the correct answer. This patient has hyperthyroidism as shown by her symptoms and laboratory results. Elevated levels of thyroid hormones can lead to irregular or absent ovulation. Hyperthyroidism may shorten the luteal phase of the menstrual cycle, resulting in a shorter and lighter menstrual flow. Additionally, weight loss can disrupt normal hormonal signalling in the body, impacting the menstrual cycle.
