Write on the effect of hormonal changes on metabolism

Hormonal changes significantly affect metabolism, which is the sum of chemical processes that occur in living organisms to maintain life. Key hormones involved include: Thyroid hormones (T₃ and T₄): Produced by the thyroid gland, these hormones are crucial for regulating the basal metabolic rate (BMR). They increase oxygen consumption and heat production in most tissues. Low levels (hypothyroidism) slow metabolism, leading to weight gain, while high levels (hyperthyroidism) accelerate it, causing weight loss. Insulin: Secreted by the pancreas, insulin plays a central role in glucose metabolism. It promotes glucose uptake by cells, storage as glycogen in the liver and muscles, and conversion to fat. It also inhibits the breakdown of fat and glycogen. Imbalances, like in diabetes, disrupt glucose metabolism and can lead to altered energy storage. Glucagon: Also from the pancreas, glucagon counteracts insulin's effects by stimulating the breakdown of glycogen in the liver to release glucose into the bloodstream, thus raising blood sugar levels. Cortisol: Released by the adrenal glands, cortisol influences carbohydrate, fat, and protein metabolism. It promotes gluconeogenesis (glucose production from non-carbohydrate sources) and can increase appetite, potentially leading to weight gain, especially abdominal fat, when chronically elevated. Growth hormone: Produced by the pituitary gland, it promotes protein synthesis, increases fat breakdown, and influences glucose metabolism, generally increasing BMR. Adrenaline (Epinephrine) and Noradrenaline (Norepinephrine): Released by the adrenal medulla during stress, these hormones rapidly increase metabolism by stimulating the breakdown of glycogen and fat, increasing heart rate and blood pressure, and boosting energy availability. These hormones work in a complex, interconnected system to maintain energy balance and respond to the body's needs for fuel and growth. Send me the next one 📸
