What condition is characterized by weight gain, fatigue, constipation, and delayed relaxation on reflex?

• A. Hypothyroid
• B. Hypercholesterolemia
• C. Diabetes Mellitus
• D. Cushing's Syndrome

Answer: (A)

The condition characterized by weight gain, fatigue, constipation, and delayed relaxation on reflex is indeed hypothyroidism. In hypothyroidism, the thyroid gland is underactive and produces insufficient amounts of thyroid hormones, which play a crucial role in regulating metabolism.

Weight gain occurs because a lack of thyroid hormones slows metabolic processes, causing the body to burn fewer calories. The fatigue experienced is also directly related to this slower metabolism, as the body becomes less efficient in energizing itself. Constipation is a common symptom, as thyroid hormones are important for proper gastrointestinal motility; without adequate hormone levels, digestive processes slow down, leading to constipation.

Delayed relaxation on reflex – often referred to in the context of deep tendon reflexes – is another hallmark sign. In hypothyroidism, patients may show a slowed or prolonged response when assessing reflexes, reflecting the overall decreased metabolic activity and neuromuscular function.

Thus, all these symptoms align perfectly with hypothyroidism, making it the correct condition associated with the mentioned symptoms.
