Final answer:
Synthroid is prescribed to treat hypothyroidism, and it must be taken 30 minutes before a meal for proper absorption. It replaces the thyroid hormone that the underactive thyroid gland cannot produce sufficiently.
Step-by-step explanation:
Synthroid, a pill form of thyroid hormone, is commonly prescribed to treat hypothyroidism, a condition where the thyroid gland is underactive. This medication must be crushed and taken 30 minutes before a meal to ensure proper absorption and effectiveness. Hypothyroidism can occur due to various reasons, including the body's failure to produce enough thyroid hormones (T3 & T4) or due to a disease that affects the thyroid gland directly.
When the body lacks sufficient thyroid hormones, metabolism slows down, leading to symptoms such as weight gain, fatigue, and cold sensitivity. These symptoms correspond with Patient A's condition as described in the context provided. Treatment with Synthroid replaces the missing thyroid hormones, thereby helping to regulate the body's energy use and metabolism. It is essential to monitor and adjust the level of hormone replacement carefully to avoid any adverse effects and ensure appropriate treatment.
